All Implemented Interfaces:

LightmappedShape

public class LightmappedTriangle
extends TexturedTriangle
implements LightmappedShape

A textured triangle whose texture is a GI-generated lightmap composite (baseColor x lighting). UVs are fixed at (0,0), (width,0), (0,height) (engine UVs are in texture pixel units): the whole triangle is covered by its own lightmap, valid region u+v <= 1 in normalized coordinates.

Shading via LightingManager does not apply — all light (ambient, direct with shadows, indirect) lives in the composite texture, which the GI system regenerates and swaps in every few sweeps.

Constructor Details

LightmappedTriangle

public LightmappedTriangle(Point3D a,
 Point3D b,
 Point3D c,
 Color baseColor,
 double unitsPerTexel,
 double normalX,
 double normalY,
 double normalZ)

Creates a lightmapped triangle.

Parameters:

a - first vertex (shared coordinate reference is fine)

b - second vertex

c - third vertex

baseColor - unlit surface color

unitsPerTexel - world units per lightmap texel

normalX - unit normal x

normalY - unit normal y

normalZ - unit normal z

Method Details

repinUvToLightmap

public void repinUvToLightmap()

Pins the corner UVs to the lightmap's CURRENT dimensions and refreshes the texture-distance estimate. Called at construction and by Lightmap.refine() (stage 4 changes the texture size — without re-pinning, the painter would sample only the coarse-sized corner of the fine texture). Each vertex gets its own frame-space corner (Lightmap.cornerU/cornerV) — the bounding-rect frame may assign any corner to any vertex.

getLightmap

public Lightmap getLightmap()

Description copied from interface: LightmappedShape

Returns the lightmap for this shape.

Specified by:

getLightmap in interface LightmappedShape

Returns:

the lightmap
