I have a 2D VBO object that represent points in 2D space. What is the be开发者_高级运维st way to draw an arbitrary shape at that point? Lets say I wanted to draw a red \'X\' at each.
I use PyOpenGL to draw a 2D Image. Then I want to use the Python Imaging Library (PIL) to store this image to disk. I use GLUT to display the image which works perfectly. But when I use PIL to store t
I have an interleaved array format and I want to render it in open GL. It is an array of triangles. The vertices are 2D floating points and the colors are RGBA floating points. That is, a single trian
I\'m new to Python and PIL. I am trying to follow code samples on how to load an image into to Python through PIL and then draw its pixels using openGL. Here are some line of the code:
I have the following code: import pyglet from OpenGL.GL import * from OpenGL.GLU import * class Window(pyglet.window.Window):
I\'m writing an application that is looking to draw basic polygons and ellipses on the Windows 7 desktop using OpenGL. According to this 开发者_StackOverflowprevious question, this is possibly by gett
So the question is: when I switch from ColorPointers to Textures, it seems that the lightning/shadows effects are greatly reduced. Some solution that I have found but doesnt do that much is setting gl
I have a running program that uses glVertexPointer, glNormalPointer etc to draw a large number of elements. This works around 30 FPS. Now I\'ve reach a point where integrating shaders would be a viabl
I\'m still trying to get a grasp of using textures and now I\'m trying to use glTexCoordPointer in order to give each vertex a color specifi开发者_StackOverflow中文版c to it\'s class. I\'ve made some
EDIT Ok I added some changes to my texture rendering, and I\'m now at a point that it doesn\'t look how I want it but before I try to change anything I just want to be sure I\'m on the right path. Th
