In our last lesson, we learned how to use vertex buffer objects on Android. We learned about the difference between client-side memory and GPU-dedicated memory, and the difference between storing texture, position and normal data in separate buffers, or altogether in one buffer. We also learned how to work around Froyo’s broken OpenGL ES 2.0 … Continue reading Android Lesson Eight: An Introduction to Index Buffer Objects (IBOs)»

In this lesson, we’ll introduce vertex buffer objects (VBOs), how to define them, and how to use them. Here is what we are going to cover: How to define and render from vertex buffer objects. The difference between using a single buffer with all the data packed in, or multiple buffers. Problems and pitfalls, and what … Continue reading Android Lesson Seven: An Introduction to Vertex Buffer Objects (VBOs)»
This is the first tutorial for learning OpenGL ES 2 on the web, using WebGL.
