The GetFacePlaneUsingEdge method calculates the plane of a face in a polygon mesh using a specified edge and transformation. This method is useful for determining the geometric plane on which a face lies, which can be critical for operations like rendering, collision detection, or physics calculations.
To use the GetFacePlaneUsingEdge method, you need to provide the following parameters:
hFace: A handle to the face for which the plane is being calculated. This is of type HalfEdgeMesh.FaceHandle.hEdge: A handle to the edge that is used in the calculation. This is of type HalfEdgeMesh.HalfEdgeHandle.transform: A Transform object that represents the transformation applied to the mesh. This is used to ensure the plane is calculated in the correct space.outPlane: An output parameter of type Sandbox.Plane that will hold the resulting plane after the method execution.Ensure that the face and edge handles are valid and correspond to the same mesh to avoid unexpected results.
// Example usage of GetFacePlaneUsingEdge PolygonMesh mesh = new PolygonMesh(); HalfEdgeMesh.FaceHandle faceHandle = ...; // Obtain a valid face handle HalfEdgeMesh.HalfEdgeHandle edgeHandle = ...; // Obtain a valid edge handle Transform transform = ...; // Define the transformation Plane facePlane; mesh.GetFacePlaneUsingEdge(faceHandle, edgeHandle, transform, out facePlane); // Now facePlane contains the plane of the specified face using the given edge and transformation.
