Record TTriangleHelper

Shape containing this triangle.

State of this shape, containing various information about 3D shape. This is a shortcut for Shape.State.

Use State.Transform to update triangle TTriangle.World geometry from triangle TTriangle.Local geometry.

X3D shape node of this triangle. May be Nil in case of VRML 1.0.

Material information for the material of this triangle. See TMaterialInfo for usage description. Returns Nil when no node determines material properties (which indicates white unlit look).

Returned TMaterialInfo is valid only as long as the underlying node (TMaterialNode, TPhysicalMaterialNode, TUnlitMaterialNode, TCommonSurfaceShaderNode...) exists. Do not free it yourself, it will be automatically freed.

Return transparency of this triangle's material. Equivalent to MaterialInfo.Transparency, although a little faster.

Returns True for triangles that are transparent.

Returns True for triangles that should be ignored by shadow rays. Returns True for transparent triangles (with Material.Transparency > 0) and non-shadow-casting triangles (with Appearance.shadowCaster = FALSE).

For a given position (in world coordinates), return the smooth normal vector at this point, with the resulting normal vector in world coordinates.
