Heightfield sample format.

This format corresponds to the <a class="el" href="structPxHeightFieldFormat.html" title="Describes the format of height field samples.">PxHeightFieldFormat</a> member <a class="el" href="structPxHeightFieldFormat.html#d28e3afa439f8ff1df6067288c46d9c5a8ba1edf74a561d830b5f40e2c3e64e7" title="Height field height data is 16 bit signed integers, followed by triangle materials...">PxHeightFieldFormat::eS16_TM</a>.<p>
An array of heightfield samples are used when creating a <a class="el" href="classPxHeightField.html" title="A height field class.">PxHeightField</a> to specify the elevation of the heightfield points. In addition the material and tessellation of the adjacent triangles are specified.<p>

The triangle material index of the quad's lower triangle + tesselation flag.
<p>
An index pointing into the material table of the shape which instantiates the heightfield. This index determines the material of the lower of the quad's two triangles (i.e. the quad whose upper-left corner is this sample, see the Guide for illustrations).<p>
Special values of the 7 data bits are defined by <a class="el" href="structPxHeightFieldMaterial.html" title="Special material index values for height field samples.">PxHeightFieldMaterial</a><p>
The tesselation flag specifies which way the quad is split whose upper left corner is this sample. If the flag is set, the diagonal of the quad will run from this sample to the opposite vertex; if not, it will run between the other two vertices (see the Guide for illustrations).<p>
