Simple collision detection node.
colDetectionNode
Custom-node of collision detection part (expression node) of maya_expressionCollision.
Processing speed can be expected to improve.
Warning
Internal Use ID (0x7c001, 0x7c002) is used.
Nodes
There are two types of nodes of: input as vectors (colDetectionNode) or input as matrices (colDetectionMtxNode). These outputs are the same.

Performance
The following is the processing time for a single node when one each of sphere, capsule, and infinitePlane Collider is used, Iterations : 3, GroundCol : On.
On its own, colDetectionNode is faster, but colDetectionMtxNode may be faster as a result because it does not require decomposeMatrix, etc.

The following image shows a processing time comparison of 100 nodes when 10 capsule2 colliders are used, Iterations: 3, and GroundCol: On.
Tested:
- Windows 11
- Intel(R) Core(TM) i7-10700 CPU @ 2.90GHz
- 32GB RAM
- NVIDIA GeForce RTX 3060
Note
- Processing order of collider type cannot be changed.
- Too many colliders reduce accuracy.
