Parameters

VarNodeIDs

Array of node IDs (see Remarks)

VarNumNormals

Array of numbers (1, 2 or 3) of normal vectors for the corresponding node ID in VarNodeIDs (see Remarks)

VarNormalVecs

Array of normal vectors (see Remarks)

Return Value

You must set ICWMesh::Quality to swsMeshQuality_e.swsMeshQualityHigh before calling this method.

Each node can have one or more normal vectors. For example, for a meshed cube:

VarNormalVecs contains an array of all of the normal vectors:

[

     xa₁, ya₁, za₁, xb₁, yb₁, zb₁, xc₁, yc₁, zc₁,

     xa₂, ya₂, za₂,

     ...,

     xa_i, ya_i, za_i

]

where:

• x, y, and z denote location
• a, b, and c denote normal vectors
• xa_i, ya_i, za_i denote the location of the a^th normal vector for the i^th node

Use VarNumNormals to calculate which vectors in VarNormalVecs map to the node IDs in VarNodeIDs.
