• Copying 2D lists in python

  - by SuperString

  Hi I want to copy a 2D list, so that if I modify 1 list, the other is not modified. For 1 D list, I just do this: a = [1,2] b = a[:] And now if I modify b, a is not modified. But this doesn't work for 2D list: a = [[1,2],[3,4]] b = a[:] If I modify b, a gets modified as well. How do I fix this?

• How do you make a 2-d array in Matlab?

  - by Ben Fossen

  I want to make a 2D array dij(i and j are subscripts). I want to be able to do dij = di,j-1+(di,j-1 - di-1,dj-1)/(4^j-1) My idea for this it to make to 1D arrays and then combine them into a 2D array. Is there an easier way to do this?

• As a code monkey, how to discuss programming with a guy who almost has a doctorate in computer science

  - by Peter Turner

  A friend of my wife's is coming over for dinner tonight and he is a lot smarter than me. What do we have in common, well... A Bachelor's in Computer Science, and that should be enough of a conversation starter. But he's nearly completed his doctoral studies and is light years ahead of me in his particular area, which I find fascinating but…

• How do I become a programmer and not some guy that can type some C?

  - by Phoxxent

  From what I understand, programming has a lot more to it than learning syntax, that it involves an understanding of what happens under-the-hood and even more. Currently, I am just a guy that can pump out a few loops in Python or C and maybe make a small-scope Zork clone as the hight of skill. So, what can I do to become an actual programmer?…

• How do I protect my company from my IT guy?

  - by Jesse

  I'm going to hire an IT guy to help manage my office's computers and network. We're a small shop, so he'll be the only one doing IT. Of course, I'll interview carefully, check references, and run a background check. But you never know how things will work out. How do I limit my company's exposure if the guy I hire turns out to be evil? How…

• Solid Edge ST6 - 2D Modeling: dimensions

  - by juFo

  I'm currently making some 2D drawings in Solid Edge ST6. I have several circles which I need to change so that they have an equal diameter and equal space between both circles, etc... Currently my drawing looks a bit messy with all the dimensions that I use: I use the Smart Dimension tool and the Distance Between tool but I have no clue…

• Render a 3D image as a 2D vector image

  - by Clinton Blackmore

  Is there any software that will take a 3d model (in any format) and allow you to render it as a 2D vector image (preferable as either an .SVG or .PDF)? My intention is to render LEGO building instructions this way. While there are many tools that let you view them or generate nice, rasterized output, I'd really like to be able to generate…

• Transition from 2D to 3D later in game development

  - by Axarydax

  Hi, I'd like to work on a game, but for rapidly prototyping it, I'd like to keep it as simple as possible, so I'd do everything in top-down 2D in GDI+ and WinForms (hey, I like them!), so I can concentrate on the logic and architecture of the game itself. I thinking about having the whole game logic (server) in one assembly, where the…

• How to move positions within an array?

  - by Jade Mulholland

  A program that simply moves array elements. Two variables: userInputVariable and blankSpaceVariable. I have a 2D array named table. Defined as table[userInputVariable + 1][6] I am printing out this array in a table format, and the far left column is numbered by whatever number the user entered at the beginning of the program. I then…

• two arrays defining 2d coordinates, as array indices, in matlab/octave

  - by Jason

  Hi, I have a 2D array, call it 'A'. I have two other 2D arrays, call them 'ix' and 'iy'. I would like to create an output array whose elements are the elements of A at the index pairs provided by x_idx and y_idx. I can do this with a loop as follows: for i=1:nx for j=1:ny output(i,j) = A(ix(i,j),iy(i,j)); end end …

• Calculating 2D angles for 3D objects in perspective

  - by Will

  Imagine a photo, with the face of a building marked out. Its given that the face of the building is a rectangle, with 90 degree corners. However, because its a photo, perspective will be involved and the parallel edges of the face will converge on the horizon. With such a rectangle, is it possible to calculate the angle in 2D of the…

• Interpolating 1D Gaussian into 2D Gaussian

  - by Drazick

  Let's say I have a 1D Gaussian function. Its length is 600 for that matter. I want to Interpolate it into 2D Gaussian of the size 600 X 600. This is the code I wrote (OTFx is the Gaussian Function, OTF - 2d Interpolated Function): [x, y] = meshgrid([-300:299], [-300:299]); r = sqrt((x .^ 2) + (y .^ 2)); OTF = interp1([-300:299],…

  I have a 2d vector which represents a 2d grid; so grid[0][2] for example. I am needing to 'insert' -might not be the right word here. a vector at a specific location say grid[3][2] there will definitely be a grid[0][0] but when im needing to insert into grid[3][2] there may be nothing before it other than grid[0][0] and there…

• 2D Engine scrolling on OpenGL via hardware?

  - by drudru

  hi, I'm using OpenGL as the bottom end for a 2D tiling engine. When everything is 2D, it is simple to optimize certain issues. For example, scrolling. If I know a certain section of the screen needs to scroll off the bottom, then I can just blit over that portion. I'm evening moving more than 1 pixel at a time. Without…
