what is the best way to create a gradient for a 2D polygon in OpenGL, (Linear, and Radial)?
Thanks
How can you generate textures for radial gradients on the fly?

OpenGL 3 equivalent of GLUTesselator?
- by user146780
I was wondering, since things like display lists are now deprecated, I'm thinking the GLU polygon tesselator is probably also deprecated. What is the new and correct way of creating concave or complex polygons and complying with the new GL 3 standard? Thanks.Read the article

Google Maps newbie (GIS newbie), I'm looking at a solution to map an overlay (number of polygons) on-top of Google maps and wondered if using a KML file was a viable solution? Basically, I have a number of address (address data) that I will pass to our internal GIS system, the GIS system hands me back a KML file (one file with a number of…Read the article

GoogleMaps API extracting building shape information.
- by manionml
Hi, I'm looking for a way to extract building shape (polygon) information from google maps automatically. It appears that you can only downloaded information relating to shapes you've created yourself. Example here. Information relating to building shape and height is stored by google, so I'm hoping there's a way to extract it.Read the article

How do I use ST_Contains in following case?
- by Z77
I have two tables. First with points, and second with polygons. I need to find out which points are in required polygon according to the attribute gid. Using query: SELECT table1.* FROM table1, table2 WHERE table2.gid=1 AND ST_Contains(table2.geom2, table1.geom1); What I get is empty table (only columns without data)... TnxRead the article

Make openGL lines connected
- by user146780
Right now I'v created a polygon, then I do the same thing but with line_loop to draw the outline. My issue right now is if I set the line thickness to high, the lines arn't connected. Their ends would need to be (linewidth) longer... is there a way to fix this? ThanksRead the article

500 Metro Style WP7 Icons

I was inspired by The Noun Project, a project that offers up “Metro-style” icons in SVG format. The project is licensed under a public domain license and while it’s a great project, all of the content is in SVG format. Jon Galloway has a great post (from 2007) talking about the differences between SVG and XAML so I highly recommend that…Read the article

Are there any font rendering libraries for games development that support hinting?
- by Richard Fabian
I've used angel code's bitmap font generator quite a bit and though it's very good, I wondered if there would be a way of using the hinting information to provide a better readable result by using hinting to provide differing thickness based on size/pixel coverage. I imagine any solution would have to use the distance field tech…Read the article

How to fix bad Collada produced by FBX?

I tried to use the FBX SDK (2011.3.1) to load FBX files and save them as Collada files in order to be able to import FBX files in Panda3D. Unfortunately the resulting Collada files are not usable for several reasons, among them: There's a Maya specific extra technique diffuse <diffuse> <texture…Read the article

Slick2D + LWJGL collision system

So I've been learning java for a while and have explored slick and lwjgl before but went away from using Slick for a while. But I've recently gone back to using it (as I'm making a platformer and Tiled will be really helpful). But here's where my problems begin: collision. I have a player polygon and I check…Read the article

How can I calculate a vertex normal for a hard edge?

Here is a picture of a lovely polygon: Circled is a vertex, and numbered are its adjacent faces. I have calculated the normals of those faces as such (not yet normalized, 0-indexed): Vertex 1 normal 0: 0.000000 0.000000 -0.250000 Vertex 1 normal 1: 0.000000 …Read the article
