Member Function Documentation

Create()

virtual bool trax::GeomHeightField::Create ( const short * pSamples, const bool * pbHoles, int nRows, int nCols, Real vertScale, Real horzScale )

pure virtual

Creates a heightfield from data.

The quads are tesselated as [i],[i+nCols+1],[i+1] and [i],[i+nCols],[i+nCols+1]. If all three adjacent samples of a triangle have the cooresponding hole information flag set to true, the triangle would not be created as a collision shape.

Parameters

pSamples	Array with the elevation data of the sample points. Length must be at least nRows*nCols.
pbHoles	Array with the hole information. Length must be at least nRows*nCols.
nRows	Number of rows in the heightfield.
nCols	Number of columns in the heightfield.
vertScale	Vertical scale factor.
horzScale	Horizontal scale factor.

CreateEEPStyle()

virtual bool trax::GeomHeightField::CreateEEPStyle ( const short * pSamples, const bool * pbHoles, int nRows, int nCols, Real vertScale, Real horzScale )

pure virtual

creates a heightfield from data in the EEP style.

There will only be quads erased, no single triangles. A quad is erased if its topleft, topright and bottomright sample show the hole flag.
