[vtk-developers] Using Draw() from vtkOpenGLPolyDataMapper with Python Wrapper

[Brad Hollister]

Hi,

So, I am wanting to specify user-defined vertex attributes since the 
vtkOpenGLPolyDataMapper class doesn't allow this. I've seen mention of 
using the Render() from a mapper:

http://vtk.1045678.n5.nabble.com/OpenGL-with-VTK-td5685633.html

However, I believe the posting may be wrong or out-of-date regarding 
Render(). It looks like the Draw() function:

virtual int vtkOpenGLPolyDataMapper::Draw(vtkRenderer * ren,vtkActor 
*a)
Draw method for OpenGL.
http://www.vtk.org/doc/release/7.0/html/classvtkOpenGLPolyDataMapper.html#a07de87549ffc824200b5e2eca5b4df97

is the way to go here.

Are there any examples of this being used? I am using the Python 
interface, so this should be possible in Python.

Regards,
Brad
