CSMFrustum

This class is mainly intended for use internally by DirectionalLightShadowCSM for calculating subfrustums.

Constructor

CSMFrustum()

Creates a new CSMFrustum.

Properties

# .vertices : Object

Contains 8 points forming the frustum.

• near — array of points forming the near plane.
• far — array of points forming the far plane.

Methods

# .setFromProjectionMatrix(matrix : Matrix4, maxFar : Float) → this

• matrix — view camera's projection matrix.
• maxFar — frustum far plane distance.

Sets frustum points from projection matrix.

# .split(breaks : Array, target : Array, fitToScene : Boolean) → this

• breaks — array of split intervals.
• target — array of subfrustums, should be target.length <= breaks.length.
• fitToScene — if true, uses fit to scene else fit to cascade method.

Splits this frustum into subfrustums.

# .toSpace(matrix : Matrix4, target : this) → this

• matrix — matrix applied to each frustum point.
• target — frustum to which the results will be written.

Multiplies each frustum point by a matrix and write the results to the target.
