Shows an application of the openGL generic-data visualising node. (see previous entry)





The node is being used to visualise 'curvature' under 'real-time' manipulation of a NURBS surface.

Currently supports only one surface at a time. V 1.0, based on a hardware shader node however, supports multiple objects.

Curvature values are computed from the 'derivative' information that the maya API provides access to. As such the numeric results are accurate (verified by comparision in Rhino). Only gaussian and mean curvatures curvatures can be displayed.

The color regions are dynamic divisions of the min-max range, which can be set.
