Detailed Description

This class is used to describe the general material properties of the Terrain.

Properties that govern the contact properties in the shovel <-> soil aggregate and soil aggregate <-> terrain contacts during excavation.

When a TerrainMaterial instance is added to a terrain object, it affects the soil failure zone characteristics and feedback forces and also calibrates the internal contact materials governing soil dynamics. All the different parameters are grouped into different objects that reflects the phenomena that they affect:

BulkProperties - Holds the overarching bulk properties of the terrain and mainly affect excavation zone shapes, penetration resistance and contact material properties for excavation feedback forces.

CompactionProperties - Properties with regards to the compaction algorithm used in the terrain.

ParticleProperties - Properties that govern the soil dynamics of created soil particles during excavation, which is expressed via the contact material parameters within the soil particles and without.

ExcavationContactProperties - Properties that govern the contact properties in the shovel <-> soil aggregate and soil aggregate <-> terrain contacts during excavation.

These objects can be extracted from the TerrainMaterial instance in order to change the Terrain characteristics.

Note that using any of the set methods on a TerrainMaterial instance will cause it to recalibrate the set method's governing contact material parameter in the terrain instance. This can override any previous manual user setting of the terrain contact material.

The contacts have virtual depth that increases when the separation plane of the excavation presses against the plane of the aggregate <-> terrain contact. This class contains properties for governing the depth and force properties of those contacts.
