Features Preview

Added

• New entity EdgeMesh one dim structure for rods/ropes/trees/etc. simulation (including implementation of basic constraints and components).
• New entity Points Locker for locking the bodies. It can be used to lock points' positions during runtime (statically or dynamically).
• New entity Point Point Connector to connect entities that implement IPointsProvider. The implementation includes basic generators and a few utilities.
• New constraint Stencil Bending Constraint preserving rest angle.
• New constraint Position Constraint (two variants: soft and hard one) preserving rest position.
• New constraint Point Point Connector Constraint connecting the bodies.
• A few minor utilities related to AABB were added.
• RegeneratePositionConstraintsSystem responsible for the regeneration of the constraints on transform change added.

Fixed

• Resolves the bug related to the bad transformation of the trimesh renderer. For now, TriMesh as well as its parent can be scaled, translated, and rotated, and mesh will be calculated properly.
