[PyOpenGL-Users] glDrawArrays and PyOpenGL 3.0.0a6 anything changed?

[V. A. S. <so...@es...>]

Hello,

The following code was working fine on PyOpenGL 2.0.1.09:

                 GL.glVertexPointerf(self.vertices)
                 GL.glColorPointerf(self.vertexColors)
                 GL.glEnableClientState(GL.GL_VERTEX_ARRAY)
                 GL.glEnableClientState(GL.GL_COLOR_ARRAY)
                 GL.glDrawArrays(GL.GL_POINTS, 0, xsize*ysize)

but now it does not work under PyOpenGL 3.0.0.a6:

WindowsError: exception: access violation reading 0x0BD20028

If instead of using glDrawArrays, I loop for all the vertices and colors, 
the program works (of course very slowly):

                 GL.glBegin(GL.GL_POINTS)
                 for i in range(xsize * ysize):
                     GL.glColor4fv(self.vertexColors[i])
                     GL.glVertex(self.vertices[i])
                 GL.glEnd()

(by the way I also had to change from glVertexf to glVertex in order to get 
the loop working).

The shape of my arrays are (xsize*ysize, 3) for the vertices and 
(xsize*ysize, 4) for the colors. Do I have to arrange my data in other way 
now? I have tried to use glVertextPointer and glColorPointer but either it 
did not work or (most likely) I could not figure out the proper parameter 
to be passed.

Any hint?

Thanks,

Armando
