GrassInstanceRecord

Remarks

Forty-eight bytes: a position and a uniform scale, a quaternion, and the two per-instance numbers the draw reads. FoliageStore.InstanceBytes plus an InstanceParameters, which is what lets a seam test compare the dispatch's output against GrassScatter's bytes rather than against an interpretation of them.

Fields and properties (8)

• public Vector3 Position

  Where the blade stands, in world space.

• public float Scale

  How big it is, uniformly.

• public Quaternion Rotation

  Which way it faces, as (x, y, z, w).

• public float Tint

  A per-blade variation, 0…1.

• public float WindPhase

  A phase offset in radians, so a clump does not move as one object.

• public float Padding0

  Declared so the record is forty-eight bytes on both sides.

• public float Padding1

  And the second half of it.

• public static int SizeInBytes

  How many bytes one of these is.

Methods (1)

• public static GrassInstanceRecord Of(in GrassBlade blade)
