Context I am doing swarm simulation using GPU programming (both OpenCL and CUDA, but not at the same time of course) for scientific purpose.
When using OpenGL VBOs you can interleave your开发者_开发知识库 data You can even interleave vertex data with other data that is for use by the CPU rather than GPU, for example.
My problem seems to be really simple but I just can\'t get the reason behind it: I have a vertex and an index buffer that get filled in with glBufferSubData. There are a couple of meshes that get fi
I\'ve invested now more than a day looking for a solution on how to render transparent textures with OpenGL on Android. Obviously others had more luck than I but after trying various solutions (e.g. T
I\'m having trouble drawing with VBOs.Using immediate mode, I can easily draw a cubic grid of points, but its quite slow.I wanted to use a VBO to try and speed up the drawing.I\'m using SDL/glew.My ou
People constantly tell me to use at least Vertex Arrays. But i think its not a good idea since i\'m using glPushMatrix() with glTranslatef/glRotatef to position an object in the 3d world.
I\'m pretty new to OpenGl and am having trouble displaying a VBO based grid mixed with normal 3D objects.
I\'m creating a tile-based game in C# with OpenGL and I\'m trying to optimize my code as best as possible.
I have many particles who\'s vertices change every frame.The vertices are currently being drawn using a vertex array in \'client\' memory.What performance characteristics can I expect if I use a verte
In my current project I render a series of basically cubic 3D models arranged in a grid. These 3D tiles form the walls of a dungeon level in a game, so they\'re not perfectly cubic, but I pay special
