You have to do the floating point -> fixed point conversion yourself, then pass the fixed-point values to opengl. Something like:
IntBuffer vertexBuffer = ....; loadVertexData(vertexBuffer); gl.glVertexPointer(3, GL10.GL_FIXED, 0, vertexBuffer); On Oct 13, 9:57 am, Doodler <pedrojru...@gmail.com> wrote: > Hello, > > This is my first post in Google Groups. > > I've started developing an OpenGL ES app and I would like to get the > best possible performace (as everybody, I guess). > > As far as I know, HTC Magic (myTouch, G2) doesn't have floating point > unit, so I think every calculation is done internally with fixed point > math.
