Height field height data is 16 bit signed integers, followed by triangle materials.
<p>
Each sample is 32 bits wide arranged as follows:<p>
<div align="center">
<img src="heightFieldFormat_S16_TM.png" alt="heightFieldFormat_S16_TM.png">
</div>
<p>
1) First there is a 16 bit height value. 2) Next, two one byte material indices, with the high bit of each byte reserved for special use. (so the material index is only 7 bits). The high bit of material0 is the tess-flag. The high bit of material1 is reserved for future use.<p>
There are zero or more unused bytes before the next sample depending on PxHeightFieldDesc.sampleStride, where the application may eventually keep its own data.<p>
This is the only format supported at the moment.<p>
