Hello,
I have a VBO which should make a square grid:
#Numeric is "import numpy as Numeric"
class glLibCausticGrid:
def __init__(self,size):
self.size = size
self.size_squared = size*size
threedimensionalgrid =
Numeric.dstack(Numeric.mgrid[0:size,0:size,0:1])/float(size1)
threedimensionalgrid =
threedimensionalgrid.reshape(self.size_squared,3)
self.vertex_vbo = vbo.VBO(threedimensionalgrid)
def draw(self):
glEnableClientState(GL_VERTEX_ARRAY)
self.vertex_vbo.bind()
glVertexPointerf(self.vertex_vbo)
glDrawArrays(GL_POINTS,0,self.size_squared)
glBindBuffer(GL_ARRAY_BUFFER,0)
glDisableClientState(GL_VERTEX_ARRAY)
def __del__(self):
self.vertex_vbo.delete()
When it is drawn, I get an incorrect resultthe vertices are all over the
place in semiordered, but incomprehensible patterns. I really need it to
be a grid. Pointers?
Thanks,
Ian
