Hi!
Im working with OpenGL ES 1.0 on Android.
I wrote a .OBJ model importer, but it starts to lag with bigger models.
So i tried just to call the gl.glDrawArrays() Method 1000 times in the...

When i try gl.glenable(gl10.gl_cull_face);, the triangle disappears. I tried only adding gl.glCullFace(GL10.GL_Front_and_Back); but it has the same problem as if i add nothing...
I also tried to...

And it worked!
Maybe i looked at the back of it? How can i apply CullFace?...

I think i got it, but there is still a problem.
My Eyepoint is at 0,0,0 looking to 0,0,1.
In my mind, when the nearVal is 1, the triangle (0/0/1, 0.5f/1/1, 1/0/1) should be shown very big on the...

But why does the nearVal and farVal affect the Position of the Triangle on the Screen?

Hi!
I just started with opengl/Android programming. (previously i worked with C# and XNA...)
I made my first Triangle, but i can't apply a perspective view.
I tried to find an example, but that's...
