Methods

ContourFacet(int, int, int, out Vector3[], out Vector3[], out Vector2[], out int[])

Create a contour slice through a 3 vertex facet.

public void ContourFacet(int index0, int index1, int index2, out Vector3[] newPositions, out Vector3[] newNormals, out Vector2[] newTextureCoordinates, out int[] triangleIndices)

Parameters

index0 int

The 0th point index.

index1 int

The 1st point index.

index2 int

The 2nd point index.

newPositions Vector3[]

Any new positions that are created, when the contour plane slices through the vertex.

newNormals Vector3[]

Any new normal vectors that are created, when the contour plane slices through the vertex.

newTextureCoordinates Vector2[]

Any new texture coordinates that are created, when the contour plane slices through the vertex.

triangleIndices int[]

Triangle indices for the triangle(s) above the plane.
