Re: [PyOpenGL-Users] Missing VBO function

[Ian M. <geo...@gm...>]

That *was* a complete example of how to use the functions :-)

Here, I've added enough surrounding code to be self-explanatory.

#Import it:
from OpenGL.arrays import vbo
import numpy as np
...
#Create a vertex buffer object
vertices = [  [0,0,0],[0,1,0],[1,0,0],  [2,0,0],[0,3,0],[4,9,6],
[7,8,1],...]
vertex_buffer_object =
vbo.VBO(np.array(vertices,"f"),usage='GL_STATIC_DRAW')
...
#Draw VBO
glEnableClientState(GL_VERTEX_ARRAY); glVertexPointerf(vertex_buffer_object)
glDrawArrays(GL_TRIANGLES,0,len(vertices)/3)
glDisableClientState(GL_VERTEX_ARRAY);
glBindBuffer(GL_ARRAY_BUFFER,0)

Normal, and texture VBOs work very similarly.  Vertex attribute VBOs require
you to specify a shader, but you'll only need those for things like normal
mapping, etc.

If you need more explanation, try:
http://pyopengl.sourceforge.net/context/tutorials/shader_1.xhtml, or Google:
"from OpenGL.arrays import vbo".  My implementation is here:
http://www.pygame.org/project-glLib+Reloaded-1326-.html, in
glLib/glLibObjects.py (class glLibObject) but it's probably too convoluted
for a tutorial.
