MeshInstanceView

Remarks

⚠ The camera is here because the selection outline needs it per vertex. An inverted hull is the object's own geometry pushed outwards across the view by a width measured in pixels, which is a different world distance at every vertex and in every projection. The host used to have every vertex in hand and could do that arithmetic itself; a path that uploads geometry once cannot, so what crosses the boundary is the four numbers the arithmetic is made of.

Fields and properties (6)

• public Matrix4x4 ViewProjection

  The world-to-clip matrix.

• public Vector3 Position

  Where the camera is.

• public Vector3 Forward

  Which way it looks. Expected to be unit length.

• public float NearPlane

  Its near plane, which floors the depth the pixel scale is taken at.

• public bool Orthographic

  Whether the projection is orthographic.

• public float PixelScale

  How many world units a render pixel is: the whole answer for an orthographic view, and the factor a perspective one is linear in depth by. See WorldPerPixel.

Methods (2)

• public MeshInstanceView(Matrix4x4 ViewProjection, Vector3 Position, Vector3 Forward, float NearPlane, bool Orthographic, float PixelScale)

  The camera a frame's instances are drawn from.

• public float WorldPerPixel(Vector3 at)

  How many world units a render pixel is at a point.
