Hi!
Can anyone tell me how to use vertex Array?
I use this code. I want to use it to speed up the drawing of a heightMap.
glEnableClientState(GL_VERTEX_ARRAY);
glVertexPointer(3, GL_INT, 0, vertex);
glDrawElements(GL_QUADS, height*width, GL_UNSIGNED_INT, vertex);
glDisableClientState(GL_VERTEX_ARRAY);
vertex is a very long array of heightMap data.
(i.e the data that is used is from a.tga picture .)
