BoxSoup

Description

sealed class Tinman.Terrain.Util.BoxSoup

The BoxSoup represents a soup of 3D boxes in terrain-space.

The box soup is populated with the Add methods. Call Clear to remove all boxes. Clipping against arbitrary planes in terrain-space is done with the Clip method.

Use Vertices, Edges and Faces to visualize the box soup, for example the bounding boxes of all terrain mesh sectors in the view-frustum.

Use Points to obtain a point soup of all clipped boxes. This can be used to create fitted convex hulls, for example.

Public / Attributes

Bounds

public attribute Bounds → (get,set)

value : Box3D

The world bounds or Box3D.Max to disable box clipping.

Optional world bounds.

Add given boxes are clipped to these bounds.

Edges

public attribute Edges → (get)

value : IArrayVector<Vec2I>

[not-null]
