Instance Property

extent

The area around the anchor's position to use when projecting its texture for parallax correction.

Declaration

@property(nonatomic, readonly) simd_float3 extent;

Discussion

Rendering reflective objects may involve projecting the environmentTexture onto a proxy geometry centered on the anchor's position, then sampling from the projected texture.

An environment probe anchor may have an infinite extent, indicating that its texture is to be used as a global lighting environment, or a finite extent, indicating that the texture represents the local lightiing conditions in a specific area of the scene.
