CullInstance

Remarks

A position and a scale rather than a matrix, and not for the sake of the bytes: what every test in the traversal wants is a world-space sphere and the factor an object-space length is multiplied by, and a record carrying a matrix would be four times the size for a transform the pass would only use to derive those two. A rotation does not enter into it — the bound is a sphere.

Fields and properties (13)

• public uint FirstCluster

  Where this instance's clusters start in the cluster buffer.

• public uint ClusterCount

  How many it has, so a traversal cannot walk into another instance's DAG.

• public uint FirstRoot

  Where its roots start in the root buffer.

• public uint RootCount

  How many roots it has.

• public Vector3 Position

  Where the instance is.

• public float Scale

  The largest scale factor any axis has.

• public uint StagesLow

  The low half of the instance's Bits.

• public uint StagesHigh

  The high half of it.

• public uint Flags

  Alive when the slot holds a live instance.

• public uint Mesh

  Which registered mesh's quantization grid this instance's geometry decodes against.

• public uint FirstBone

  Where this instance's bone matrices start in the palette, or NoBones for an instance that is not skinned.

• public float MotionRadius

  How far this instance's geometry may leave its bind pose, in object space, or zero.

• public ulong Padding

  Eight bytes of tail padding the shader declares and never reads.
