[vtkusers] How to draw a checkered floor in VTK?

[kenichiro yoshimi]

Hi AC,

I don't have any idea about how to create an infinite grid, since
simulating an infinite plane would need a large meshes and they would
require a large amount of memory.  And I'm not sure if there is a way
to describe meshes periodically in VTK.

Alternatively you can use texture mapping. I do not know this way
satisfies your needs, but this might be a somewhat better than
creating large unstructured or structured grids.
I attached the sample code. I hope this will be of some help.

Best Regards,
