Detailed Description

The function node implements a gaussian function.

Member Function Documentation

◆ getAsHAPIFunctionObject()

HAPI::HAPIFunctionObject * GaussianFunction::getAsHAPIFunctionObject ( )

virtual

Returns the function as a HAPIFunctionObject.

Should return a new copy if the H3DFunctionNode stores a copy of HAPIFunctionObject since owner ship of the returned HAPIFunctionObject should be considered to belong to the caller of the function. Returns NULL if the H3DFunctionNode can not be represented as a HAPIFunctionObject.

Reimplemented from H3D::H3DFunctionNode.
