I was recently writing some OpenGL 3.3 code with Vertex Array Objects (VAO) and tested it later on Intel graphics adapter where I found, to my disappointment, that element array buffer binding is...

I want to use VAO in my native-c application for Android. The problem is, that GL_OES_vertex_array_object is supported and I can even get the addresses of glBindVertexArrayOES and glDeleteVertexAr...

Which is the best way (lowest memory, fastest speed) to texture a cube? after a while i have find this solution: data struct: GLfloat Cube::vertices[] = {-0.5f, 0.0f, 0.5f, 0.5f, 0.0f, 0.5f, 0.5...

I'm currently using the GLTools classes that come along with the Superbible 5th edition. I'm looking in the GLTriangleBatch class and it has the following code: // Create the master vertex array o...

I'm trying to draw a terrain with GL_TRIANGLE_STRIP and glDrawElements but I'm having a really hard time understanding the indices thing behind glDrawElements... Here's what I have so far: void T...
