Interface QuadView

All Known Subinterfaces:
MutableQuadView, QuadEmitter
public interface QuadView
Interface for reading quad data encoded by MeshBuilder. Enables models to do analysis, re-texturing or translation without knowing the renderer's vertex formats and without retaining redundant information.

Only the renderer should implement or extend this interface.

      Minimum block brightness. Zero if not set.

    • hasNormal

      boolean hasNormal(int vertexIndex)

      See Also:

    • lightFace

      @NotNull @NotNull Direction lightFace()
      Equivalent to BakedQuad.getFace(). This is the face used for vanilla lighting calculations and will be the block face to which the quad is most closely aligned. Always the same as cull face for quads that are on a block face, but never null.

      Parameters:
      target - Target array for the baked quad data.
      targetIndex - Starting position in target array - array must have at least 28 elements available at this index.

    • toBakedQuad

      default BakedQuad toBakedQuad(Sprite sprite)
      Generates a new BakedQuad instance with texture coordinates and colors from the given sprite.
      Parameters:
      sprite - MutableQuadView does not serialize sprites so the sprite must be provided by the caller.
      Returns:
      A new baked quad instance with the closest-available appearance supported by vanilla features. Will retain emissive light maps, for example, but the standard Minecraft renderer will not use them.

    • spriteColor

      @Deprecated default int spriteColor(int vertexIndex, int spriteIndex)
      Deprecated.
      Use color(int) instead.

    • spriteU

      Deprecated.
      Use toVanilla(int[], int) instead.
