Interface DrawOpVariants

Variant configuration for a Lambert-style DrawOp that has up to six pre-compiled DrawTechniques — one per (hasNormals, hasUVs, triplanar) combination (with hasUVs && triplanar excluded by construction). Only the flat/no-UVs technique is required; missing variants fall through to closer matches at draw time.

interface DrawOpVariants {
    technique: DrawTechnique;
    withNormals?: DrawTechnique;
    withNormalsAndTriplanar?: DrawTechnique;
    withNormalsAndUVs?: DrawTechnique;
    withTriplanar?: DrawTechnique;
    withUVs?: DrawTechnique;
}

Properties

technique

technique: DrawTechnique

Flat-shaded, no UVs. Always required.

OptionalwithNormals

withNormals?: DrawTechnique

Smooth-shaded, no UVs. Used when batch has normals but no UVs.

OptionalwithNormalsAndTriplanar

withNormalsAndTriplanar?: DrawTechnique

Smooth-shaded triplanar — textured material on UV-less geometry, world-space sampling with blend weights derived from per-vertex normals rotated to world space.

OptionalwithNormalsAndUVs

withNormalsAndUVs?: DrawTechnique

Smooth-shaded, with UVs. The texture-ready PBR variant.

OptionalwithTriplanar

withTriplanar?: DrawTechnique

Flat-shaded triplanar — textured material on UV-less geometry, world-space sampling with face-normal blend weights derived from dFdx/dFdy(vWorldPos).

OptionalwithUVs

withUVs?: DrawTechnique

Flat-shaded, with UVs. Rare; included for completeness.
