/**
|
|
* A height field object. Height fields work in a similar way as triangle
|
|
* meshes specified to act as height fields, with some important differences:
|
|
*
|
|
* Triangle meshes can be made of nonuniform geometry, while height fields are
|
|
* regular, rectangular grids. This means that with PhysxHeightField, you
|
|
* sacrifice flexibility in return for improved performance and decreased
|
|
* memory consumption.
|
|
*
|
|
* Height fields are referenced by shape instances of type
|
|
* PhysxHeightFieldShape.
|
|
*
|
|
* To create an instance of this class call
|
|
* PhysxManager::create_height_field(), and PhysxHeightField::release() to
|
|
* release it. This is only possible once you have released all of its
|
|
* PhysxHeightFiedShape instances before.
