The ComputeFaceNormal method calculates the normal vector of a specified face in a polygon mesh. This method is essential for determining the orientation of a face, which is crucial for rendering and physics calculations.
The ComputeFaceNormal method calculates the normal vector of a specified face in a polygon mesh. This method is essential for determining the orientation of a face, which is crucial for rendering and physics calculations.
To use the ComputeFaceNormal method, you need to provide a face handle that identifies the face whose normal you want to compute. The method will output the normal vector through the pOutNormal parameter.
Ensure that the face handle provided is valid and corresponds to a face in the mesh. The normal vector is calculated based on the vertices of the face and is returned as a Vector3 reference.
// Example usage of ComputeFaceNormal PolygonMesh mesh = new PolygonMesh(); HalfEdgeMesh.FaceHandle faceHandle = ...; // Obtain a valid face handle Vector3 normal; // Compute the normal of the specified face mesh.ComputeFaceNormal(faceHandle, out normal); // Use the normal vector for further processing // e.g., lighting calculations, collision detection, etc.
