Function Documentation

GU_API bool GUexpensiveMatchAndMerge ( GU_Detail dest,
const GU_Detail src 
)

Perform attribute matching and merging on two details. This may be significantly more expensive since the source detail is considered constant. If the source is constant and attributes need to be promoted, the source is duplicated before merging.

GU_API bool GUmatchAttributesAndMerge ( GU_Detail dest,
const UT_Array< GU_Detail * > &  sources 
)

Merge multiple geometry details into a single detail.

Before merging, this function will perform analysis on the input details to ensure that attributes will be promoted to a level which will prevent any loss of data.

For example, if one source detail has a point attribute which matches a vertex attribute on another source, the attribute will be promoted to a vertex attribute before merging.

In addition, if any geometry has detail attributes which have different values from other geometry detail attributes, the attributes will be promoted to primitive attributes to preserve the information.

Note
The source details must be non-const since attributes may be promoted.
GU_API bool GUmatchAttributesAndMerge ( GU_Detail dest,
GU_Detail src 
)

Perform attribute matching and merging on two details.

GU_API bool GUmatchAttributesAndMerge ( GU_Detail dest,
GU_Detail *const sources,
int  nsources 
)

Perform attribute matching and merging on an array of details.
