Excellent tutorial, you explain these stuff really well. I don’t know much about openGL and it’s the first tutorial I feel I really understood

When I ran the app, it always said The (app name) has stopped unexpectedly.

What might be the problem???

I find this an excelent tutorial.

I have several objects, including a torus as in this example.
A torus has quite some symmetry. I can make one big buffer including al the vertices of the torus, and call the draw function once every frame, or i can make a small patch of the torus an call this patch 16 times per frame with different position/ orientation. What will give the best performance?

Thanks alot

Man this tutorial makes more sense than the stock android one.

So basically, we need to make a custom class for each particular shape we want to render?

I’m used to just rendering in straight OpenGL, and not OpenGL ES, so this is somewhat foreign to me.

I feel like there has to be some simple library which contains all of the rendering classes for each of the primitive shapes?

I confess, I’m a newb and just want to take as many shortcuts as possible to get up and running, but does such a library exist?

Hi,

A very good tutorial for beginner like me.

But I was wondering, instead of declaring the vertices and indices manually one by one for the cube, do we have other method?

Please..
