Does interleaving in VBOs help or hinder proformance?

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.[详细]

OpenGL ES: glBufferSubData fills meshes into VBO/IBO, then glDrawElements renders only the first mesh instead of all of them

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[详细]

Problems displaying transparent textures with OpenGL ES on Android

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[详细]

OpenGL VBO not displaying

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[详细]

OpenGL: How to design efficient rendering system using vertex arrays with depth sorting?

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.[详细]

Is using Vertex Buffer Object's for very dynamic data a good idea performance-wise?

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[详细]

Mesh deformation and VBOs

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[详细]
