Detailed Description

Physics utilities for effectors and collision.

Definition in file depsgraph_physics.cc.

Enumeration Type Documentation

CollisionComponentFlag

enum class CollisionComponentFlag : uint8_t

strong

Flags to store point-cache relations which have been calculated. This avoid adding relations multiple times.

Note

This could be replaced by bit-shifting eDepsObjectComponentType values, although this would limit them to integer size.

Enumerator
None
Transform	DEG_OB_COMP_TRANSFORM is set.
Geometry	DEG_OB_COMP_GEOMETRY is set.
EvalPose	DEG_OB_COMP_EVAL_POSE is set.
