SceneShape

Remarks

One key for two things, because a batch is a batch either way. The viewport groups entities that share geometry into one instanced draw, and whether that geometry came out of MeshPrimitives or out of a bundle changes nothing about the grouping, the instancing or the pipeline. What it changes is where the vertices come from, which is Shape's business alone.

⚠ A PrimitiveKind of zero is Cube, so the discriminator has to be the reference and not the kind. Defaulting a key would otherwise mean "every entity is a cube", which is a viewport full of cubes where the meshes should be — and the meshes are exactly what nobody had yet, so it would have looked like the feature simply not working.

Fields and properties (7)

• public PrimitiveKind Kind

  Which primitive, when this names one.

• public AssetReference Mesh

  Which mesh asset, when it names one instead.

• public Entity Owner

  Whose edited mesh, when it names one of those.

• public int Version

  Which revision of that mesh — see SceneDocument.MeshVersion.

• public int Group

  Which face group of it, or −1 for the whole mesh.

• public bool IsAsset

  Whether this names an authored mesh rather than a built-in shape.

• public bool IsEdit

  Whether this names one entity's own edited geometry.

Methods (4)

• public SceneShape(PrimitiveKind Kind, AssetReference Mesh, Entity Owner = default(Entity), int Version = 0, int Group = -1)

  What a run of entities draws: a built-in shape, or a mesh an artist authored.

• public static SceneShape Of(PrimitiveKind kind)

  A key for a built-in shape.

• public static SceneShape Of(AssetReference mesh)

  A key for an authored mesh.

• public static SceneShape Of(Entity owner, int version, int group = -1)

  A key for one entity's edited mesh, at one revision of it.
