rprHeteroVolumeSetDensityLookup

Sets a lookup map array on the volume for density.

Values from the density data grid will reference a value in this mapping array. If a grid value is between two lookup array values, it will be linearly interpolated.

rpr_status rprHeteroVolumeSetDensityLookup(	rpr_hetero_volume heteroVolume,
	rpr_float const * ptr),
	rpr_uint n);

Parameters

Parameter	Description
heteroVolume	The heterogenous volume to set mapping on.
ptr	An array of values to set.
n	Length of the array.

Return

Returns RPR_SUCCESS in case of success, or RPR_ERROR code if a problem was encountered.
