HDK 14 version how to get GEO_Point from GU_Detail

[jinso001]

In HDK 14 version, there is major changes that GU_Detail doesn't include GEO_Point anymore. 

 

Here is code in previous version 

 

function ( const GU_Detail* gdp, ~~~ )

{

    GEO_Point* ppt;

    GA_FOR_ALL_GPOINTS_( const_cast<GU_Detail *> (gdp), ppt ) {

          UT_Vector4 position = ppt->getPos();

 

          ~~~~~

    }

}

 

In HDK14, GU_Detail doesn't support GEO_Point anymore. 

 

How I can get the GEO_Point data from GU_Detail class in HDK 14 ? 

 

( This code is part of tool which converts Houdini particle data to custom particle cache. )

 

Thanks for reading.

GEO_Point was pretty much deprecated in H12 when the base geometry library was rewritten. It only existed in some ultra slow backwards compatibility layer. What you want is something more like:

void f(const GU_Detail* gdp, ...)
{
    for (GA_Offset ptoff : gdp->getPointRange())
    {
        UT_Vector3 position = gdp->getPos3(ptoff);
        ...
    }
}

If you don't have a sufficiently modern C++ compiler (which everyone should have), then you can replace the range-based for loop with "UTforEach(GA_Offset ptoff, gdp->getPointRange())" via #include <UT/UT_ForEach.h>

PS. If you're only porting old pre-H12 code now, you should first read:
