Public / Methods

Compute

_2 overloads

public method Compute¹ → (5)

v ⁱⁿ : int32: The vertex index.
l ⁱⁿ : int32: Index of left parent or -1 if none.
r ⁱⁿ : int32: Index of right parent or -1 if none.
g ⁱⁿ : int32: Index of grand parent.
a ⁱⁿ : int32: Index of ancestor.

Computes a new vertex.

This method is called for regular vertices that are create with:

public method Compute² → (4)

v ⁱⁿ : int32: The vertex index.
hx ⁱⁿ : int32: Heightmap X-coordinate, relative to HeightmapsUtil.MaxSize.
hy ⁱⁿ : int32: Heightmap Y-coordinate, relative to HeightmapsUtil.MaxSize.
hz ⁱⁿ : int32: Heightmap Z-coordinate, relative to HeightmapsUtil.MaxSize.

Computes a new vertex.

This method is called for skeleton vertices that are created in Rtin.Create.
