Overview

MeshPainterScript can be used to do arbitrary rendering of a mesh under script control. For example, the following script renders mesh points as blue dots:

#python

from OpenGL.GL import *

glPushAttrib(GL_ALL_ATTRIB_BITS)
glDisable(GL_LIGHTING)
glPointSize(5)
glColor3d(0, 0, 1)

glBegin(GL_POINTS)
for point in Mesh.points():
	glVertex3d(point[0], point[1], point[2])
glEnd()

glPopAttrib()

Note that you must have OpenGL bindings installed for your script engine - Python in this case. On most platforms this is a separate download - check with your distribution on how to obtain PyOpenGL first, or visit http://pyopengl.sourceforge.net

Script Environment

The following parameters will be available to your script at runtime (see the documentation for your script engine for details on how these parameters can be accessed programmatically).

Name	Description

Node	A reference to this node.
