classAlphaNormals

@codexo/exojs-lighting / lighting / stable

Normals derived from a texture's own alpha channel, computed once. ```ts crate.material = new LitMaterial({ lighting, normals: new AlphaNormals(crateTexture) }); ``` The silhouette read as a height field, which gives edges that turn away from the light without anyone authoring a map. It knows nothing about the interior of a shape, so it is a floor rather than a replacement - but it is the difference between art that reacts to light and art that does not. The source must be drawable at construction: a texture that is still loading yields a flat map rather than waiting.

Constructors1
new(texture: TextureA static GPU texture sourced from an image, canvas, or video element. Holds the pixel source, its sampling state (ScaleModes, WrapModes) and its upload state (…, options?: DeriveNormalsOptionsTuning for deriveNormalsFromAlpha.): AlphaNormals
Properties2
convention: NormalConventionWhich way up a tangent-space normal map's green channel is authored. `opengl` is the canonical input convention of this package: green above the midpoint means…
Derived maps are written in the canonical convention.
