• Unity 3D coding language, C# or JavaScript [on hold]

  - by hemantchhabra

  Hello to the gaming community. I am a budding game designer, learning to code for the first time in my life. I did learned c++ in school, 8 years back, so I sort of understand the logic when people are doing coding and I can suggest them the right route also, but to an extent I can't code. I am beginning to learn coding for Unity 3D. Which one do you suggest is more versatile and easier to work on for future, because I am a game designer not a coder, I would do coding until I don't have anyone else to code for me. It should be easy and fast to learn, functional and universal to apply, and innovative at the same time. C# or JavaScript ? Thank you for your time Ps- if you could suggest me steps to learn and tutorials to look for, that would be just awesome.

• Rotate 3D Model from a custom position

  - by Nipuna Silva

  I have a 3D Model like above in which i want to rotate it from a given location(pointed in red) but I can only rotate it from the middle. How can I rotate it from a custom point. Edit: I successfully able to rotate the model from the below position by getting the radius of the model and applying it to the world matrix Vector3 point = new Vector3(-radius, 0, 0); world = Matrix.CreateTranslation(-radius, 0, 0); But now I cannot change the position of the object and it always centered in middle of the screen. I think that's because i applied the above code. How can I place it anywhere I want?

• Unity 3D not Working on Acer D270 w/ Intel GMA 3600

  - by amol.kamath

  I recently bought myself an Acer Aspire One D270 with the GMA 3600 graphics chipset thinking I would get some lovely graphics. However, I am stuck using Unity 2D and I cant figure out how to enable 3D. None of the fixes I have found so far have worked. Another effect of this is that I cant change the backlight brightness. So whenever I open the lid, looking at the screen is like staring into the sun. Is there a driver for it in the works? Does the 3.4 kernel support the chipset and most of all is there a way to fix this? Please help

• Simple 3D Physics engine as a part of graduation project [on hold]

  - by Eugene Kolesnikov

  I am working on my graduation project and one part of it is to simulate the motion of a rigid body in 3D space. I can use either already written physics engine or to write it myself. It's quite an interesting challenge for me, so I would like to do it myself. I am able to use either C++ or Java for programming (prefer C++). I am using Mac OS X and Debian 7. Could you suggest any guides or tutorials how to do it, can't find it anywhere... More precisely, I need a very simple engine, without collision detection, and many other things that I do not know, I just need to calculate the forces and move my body, depending on the resultant force. If you think that this task is still very difficult or there is no such tutorial, please suggest me some good and simple engine.

• 3D Paint tool in Maya

  - by Joris

  Hey everyone, could someone help me out on this question? When I am trying to texture objects in maya (for example a barrel) I want to texture it with a brush. When I try to use the 3D painting tool it al gets black even when I have a image file selected. Also the resolution is very very low of the models and textures in maya, though the texture image is very high quality. Can someone please help me? Thanks so much for helping.

• Render a 3D scene in multiple windows - extended panoramic view

  - by teodron

  Is there any resource location on how to view a 3D scene from an application or a game on multiple windows or monitors? Each window should continue drawing from where the neighbouring one left off (in the end, the result should be a mosaic of the scene). My idea is to use a camera for each window and have a reference position and orientation for a meta-camera object that is used to correctly offset the other camera. Since there are quite some elements to consider (window specs, viewport properties, position-orientation of each render camera), what is the correct way to update the individual cameras considering the position and orientation of the central, meta-camera? I currently cannot make the cameras present the scene contiguously (and I am reluctant in working out the transformations without checking whether this is the actual way of doing things).

• 3D Collision help

  - by Taylor

  I'm having difficulties with my project. I'm quite new in XNA. Anyway, I'm trying to make 3D game and I'm already stuck on one basic thing. I have terrain made from a heightmap, and an avatar model. I want to set up some collisions for game so the player won't go through the ground. But I just don't know how to detect collisions for so complex an object. I could just make a simple box collision for my avatar, but what about the ground? I already implemented the JigLibX physics engine in my project and I know that I can make a collision map with heightmap, but I can't find any tutorials or help with this. So how can I set proper collision for complex objects? How can I detect heightmap collisions in JigLibX? Just some links to tutorials would be enough. Thanks in advance!

• Android how to get opengl 3D coordinates in ontouch event

  - by Sandy

  I created a cube in opengl and it rotates in ontouch event. To to this I created a CustomSurfaceView as follows public class CustomSurfaceView extends GLSurfaceView { @Override public boolean onTouchEvent(MotionEvent e) { float x = e.getX() float y = e.getY(); } } Here x and y are screen coordinates. How can I get 3D coordinated from this? I have already looked gluProject and NeHe. But I dont know how to implement this in my project, it shows that there is no GLdouble,GLfloat class.

• 3D architecture app for Android or iPhone

  - by Manixate

  I want to make an app for 3D modeling on iPhone/Android. I cannot get the basic idea of how to get started. I have various options such as learning OpenGL ES, UDK or Unity3d but I want to create models(e.g architecture etc) in my app and then render them when user is finished modeling. I do not know if I am able to design models and then render them in the same app with various effects on the iPhone/Android using UDK or Unity3d. (Note: If you find this question unclear please ask, I may have skipped some vital information).

• Cursor seems to freeze in the first attempt to type - Unity 3D, 12.04

  - by Denis

  It happens in the first attempt of typing, no matter is after the startup, or 5 minutes later, or then after. The cursor (or maybe it's the system) seems to freeze, no matter the application I use, taking up 4 to 5 sec to appear what is typed. Subsequently, everything is normal, using another applications. @Anwar Shah suggested it could be a daemon waiting to run before the lauching of the first application. Turning off Zeitgest didn't help. It occurs only with Unity-3d. Tested with Unity-2d, everything is fine. Tried to change some Compiz settings, nothing worked, although not tested with every single parameter. Also I deactivated Ati proprietary driver, no effect. My system: AMD E350 1.6Gh, 2G-Ram, ATI graphics - Ubuntu 12.04, 64bits. Is that what I should expect, or can be fixed or improved? Thanks.

• Tunnels in pseudo 3D racing game

  - by Nicholas

  How would one go about doing tunnels in a pseudo 3D racing game ? The main problem I have at the moment is perspective - I cant think of a way, beyond having to Z sort the sprites and tunnel coordinates, so that vehicles are displayed in front of the tunnel entrance and somehow block the display when out of site. I would like my tunnels to be used on both flat, curved and hills and slopes. The tunnel enterance/exit is made up of 3 separate graphics, (left, right and top), whilst inside the tunnel it is just one line graphic along the top (the idea being its supposed to be a set distance above the current vertical road position). As you can see from the picture, the vehicles are still being rendered whilst in the tunnel. I've converted the Code Incomplete road system to GLBasic.

• Drawing flaming letters in 3d on OpenGL ES 2.0

  - by Chiquis

  I am a bit confused about how to achieve this. What i want is to "draw with flames". I have achieved this with textures successfully, but now my concern is about doing this with particles to achieve the flaming effect. Am I supposed to have a Path in where i should add many particle emitters along the path that will "be emitting flames"? I understand the concept for 2d, but for 3d are the particles (that are quads) always supposed to be facing the user? Edit: Something else im worried about is the performance hit that will occur by having that many particle emitters, because there can be many letters and drawings at the same time. And each of these elements will have many particle emitters.

• How to tell what part of a 3D cube was touched

  - by user2539517

  I am writing a rather simple android game and I am implementing Open GL to draw a 3D cube that spins upon the X, Y and Z axis and I need to know where the user has clicked on the texture of the cube. The texture is a simple square bitmap (100x100) that has a smaller square in the center. I need to know if the user touches the inner square. As well was tell which face of the cube the user touches. Does anyone know how this can be accomplished if not can anyone give some pseudo code on how to tell where the ray correlates to the texture? Or at least point me in the right direction. The textures of each face are like this: The code I am using is from: http://www3.ntu.edu.sg/home/ehchua/programming/android/Android_3D.html2.9 It is a port to android from Lesson 6 NeHe. Example 6a: Photo-Cube

• 3D RTS pathfinding

  - by xcrypt

  I understand the A* algorithm, but I have some trouble doing it in 3D to suit the needs of my RTS Basically, in the game I'm making, there will be agents with different sizes of OBB collision boxes. I can use steering behaviours for avoiding other agents, so I don't need complete dynamic pathfinding. However, there is a problem because different agents have different collision geometry, and structures can be placed in almost any place. This means that there might be a gap between two structures where some agents can go through and some can't. A solution I have found to this problem is to do a sweep of the collision geometry of the agent from start node of the edge the pf algorithm is currently testing, to the end node of that edge. But this is probably a bit overkill since every edge the algorithm tests would also have to create and test with a collision geometry sweep. What are some reasonable approaches to this problem? I should mention that I'd prefer not to use navmeshes, I prefer waypoints because my entire system is based on it atm.

• Chrome 18 : la 3D pour tous et amélioration de l'accélération de Canvas2D

  Chrome 18 : la 3D pour tous Et amélioration de la prise en charge de Canvas2D Chrome 18 vient de passer en version stable. Au menu, une amélioration de la prise en charge de Canvas2D qui tire parti de l'accélération matérielle (et du GPU donc). Elle devrait permettre à des applications web, comme les jeux, de tourner plus rapidement. Pour Google, avec cette prise en charge, les versions 100% Web des applicatifs pourraient même être aussi performantes que les versions traditionnelles. L'accélération matérielle appliquée à Canvas2D était jusqu'ici réservée au « beta channel » de Chrome. La fonctionnalité peut donc avoir encore quelques petits ratés. [IMG]http:/...

• 3d js map rendering

  - by gotha

  In the past I've done a 2D tile map using HTML, CSS and Javascript. Now I have the task of creating a 3D version using the same technologies - think of it like a space map where all planets have x/y/z positions. Currently, I have no idea to do this. Is there an existing library or something I can modify to do my job? If not, what method of rendering the map should I use? It needs to be as browser independent as possible, so I can't use webgl, flash or canvas. I'm considering plain JS & HTML or SVG (using Raphael for compatibility).

• writing 3d game [closed]

  - by user1432980

  I want to write a game as my final year diploma project.(I'm a 4th-year-student now so I've got a year and several months). But I don't know what to choose: either write my own game engine using DirectX9(10)(I don't like OpenGL) or use OGRE + PhysX(Don't like Unity) I'm more interested in writing my own game engine(but I wonder if I'll create engine on the same level as even Unreal 1.0 hah) but on the other side with PhysX I'll have advanced physics in my game and with OGRE I'll have good grahics. For 3d models I want to use Maya. What do you advise me to choose? As for me I've got a little DirectX experience,not bad C++ programming skills(but not expert's) and a little knowledge of Maya. My English isn't perfect either hah...

• Cross-platform & 3D mobile game development [on hold]

  - by Sylvia MBemba

  I am not a developer or programmer and, I am planning an educative project that will involve having students to develop a cross-platform, 3D mobile game, similar to the SimCity concept. I need to write a project requirement and I'd like to pick someone's brain to understand what's involved in developing such a project: Is it realistic to have one or two students to do it? and along their other modules at uni? How much time can it take to develop from scratch? what are the different skills required?

• 3D primitive rendering library

  - by tomzx

  Hi, I am looking for a library which would easily allow me to render shapes (cubes, spheres, lines, circles, etc.) in 3D3 and OpenGL if possible. I want to be able to rapidly design visual debugging tools and I am not proefficient enough in graphics rendering to do it myself (writing the low level stuff that is). The library would have to be for C/C++. I've already taken a look at the open-source 3d engine, but I feel those are too big for what I really need. Do any of you know if such library exist? If so, links would be appreciated!

• Ideas for extending tic-tac-toe game?

  - by pimvdb

  I'm building a 3D tic-tac-toe game and this is what I've implemented so far: 3D renderer with texture mapping Playing against the computer Playing online (multiplayer) Now I'm a little lost what I could add. Obviously, tic-tac-toe isn't that exciting or advanced, but I just miss something to salt it a little bit. Therefore, could anyone please suggest some ideas that would be worth implementing? Thanks!

  I know that a cube is actually a 3d shape , but i have some other problem over here. I have been doing 2D Game dev using libgdx but have never touched 3D rendering. Now what I want in my 2D game is that instead of coins I make my player collect magical cubes. But those cubes need to be spinning on one Diagonal, same can be seen in popular game Vector. Here is a screenshot. Can someone explaing the mathematics of such an animation

• Issuse with multiple student result printing request

  - by dotman14

  I'm not really sure about how to ask this question but i'll try my best to make it clear enough. I have a Student Result Application where by students result are managed, over several academic sessions, all having two semesters each. During each semester students take different courses and have results based on the semester. The application is done now and i'm using a PDF Libaray to crop the final result page to hand over to the students each semester. If a student request a particular semester result it's a straight forward issue and there are no complications when it comes to printing out the result. My issue is this: in a case where a student requests to have a combination of semesters...say 3rd year rain semester , 4th year rain semester and 5th year hamattarn semester. Please how can i handle this issue? Does the user picks these options at the user interface level or there's a special way to handle issues like this? Also, if i'm to display these multiple student result how could this be be done, knowing fully well that i'll have to print the different result seperately. Hopefully i've being able to make my situation clear enough. Thanks for your time and patience. Expecting your comments and answers. Thanks.

• Activist shared printing material gallery

  - by Dave

  What would you say would be the best way to do this: We would like to create a section on our activist community FB page and website in order to share with everyone images and files ready for printing panflets, brochures, t-shirts, stickers, etc. Let's say we have some cool slogans for t-shirts, so we would like to show them on a gallery, and offer for download the original design files needed for a print shop to create the t-shirts. And the same thing for all other kinds of media. We want to enable anyone to be able to just download the files for free, and easily create printed materials with them. But besides offering this hybrid between picture gallery and downloads manager, we would also like to make it very easy for anyone to upload and share their own files with the community, to make it a true collaboration initiative, be it that they get posted automatically, or that we first review and approve all uploads. Cafepress or Spreadshirt let you upload your design and sell your own merchandise. We need something similar, but where people can then download working files for making quality printings and materials. What apps, tools, services or methods are out there with which you think this could be best done?? We have some ideas, but we would like to hear some more!!

• UEFI Boot Failure - Hang after Printing USB Information

  - by James

  I'm experiencing a really weird boot problem. With both 12.10 and 12.04LTS, the vast majority of kernels (and initrds) that I've tried boot, but hang immediately after printing out information about USB devices. This isn't exactly a full "hang" so to speak, as if I plug in a flash drive, I see information and a /dev/sd* entry printed to the screen. Post/pre-init scripts are not run, there is no handoff, nor busybox or VT prompt. Virtual terminals can't be changed (with Ctrl-Alt-Fx). For what I can see, init may have not been executed yet. With certain kernel and OS combinations however, (specifically 3.2.0-29), I get a full boot and am able to use the OS as if there is no problem. After 3.2.0-29, I've been hard pressed to find a kernel that works. Any idea what's happening or how to fix this? Or even a road to take? I've exhausted the first five pages of Google for every search term I can think of. This is a Lenovo Z580 (i5-3210M) with Phoenix SecureCore Tiano firmware, if that helps any.
