Collision pruning | Substance 3D Designer

Collision pruning

In: Substance model graphs > Scene management

Description

The Collision pruning node removes all elements in a scene which it intersects or comes in contact with. A tweakable collision margin and the ability to use convey hulls let you fine-tune the collision detection.

Parameters

  • Base geometry Scene
    The input scene which holds the elements which should be tested for collision, for the purpose of being removed if colliding with elements from the Pruning Geometry input scene.
  • Pruning geometry Scene
    The input scene which holds the elements which should be tested for collision, for the purpose of removing colliding elements from the Base Geometry input scene.
  • Emit collision geometry Boolean

  • Use convex hulls Boolean
    Enable more accurate collision detection by using convex hulls instead of Axis-aligned bounding boxes (AABB). The convex hull of a shape or volume is the smallest shape which can include it with the lowest amount of faces – think of a rubber band or a tightly fit plastic wrap.
  • Collision margin Float
    Adds a distance margin from the surface of elements in the Pruning Geometry input scene to detect collision by proximity in addition to intersection and possibly inclusion.
  • Use quantized AABB compression Boolean
    Use a compression algorithm to simplify collision detection between Axis-aligned bounding boxes (AABB). Improves performance and memory usage at the cost of accuracy since the quantization step involves mapping the vertex coordinates to a limited set of values with of predefined precision, which is a lossy operation.
