so I wrote this but it doesn't do anything...can anyone help..

Your vertex pointer needs to be an array of the actual vertices while your index array should be an array of INDEXes into the vertex array.

so are you saying I''m using the wrong pointer?

quote:
glVertexPointer(4, GL_UNSIGNED_BYTE, 0, indices);

You''re telling OpenGL to use your index array as vertex array. Meaning, it will use the index array to get the vertex data. In this case, OpenGL will think the first vertex in the array has the coordinate (x,y,z,w)=(4,5,6,7), the second vertex has coordinate (1,2,6,5), and so on.

What you need to do is to create a second array which holds the vertices. A quick look in the index arrays tells me you''re trying to draw a cube, and if so, you should have an array of vertices with the coordinates of the 8 corners of the cube.
