26 /**
27  * A height field object. Height fields work in a similar way as triangle
28  * meshes specified to act as height fields, with some important differences:
29  *
30  * Triangle meshes can be made of nonuniform geometry, while height fields are
31  * regular, rectangular grids. This means that with PhysxHeightField, you
32  * sacrifice flexibility in return for improved performance and decreased
33  * memory consumption.
34  *
35  * Height fields are referenced by shape instances of type
36  * PhysxHeightFieldShape.
37  *
38  * To create an instance of this class call
39  * PhysxManager::create_height_field(), and PhysxHeightField::release() to
40  * release it. This is only possible once you have released all of its
41  * PhysxHeightFiedShape instances before.
