The SetTextureOffset method is used to set the texture offset for a specific face in a polygon mesh. This method allows you to adjust the texture mapping by specifying an offset in the texture coordinates, which can be useful for aligning textures or creating specific visual effects on the mesh surface.
To use the SetTextureOffset method, you need to provide a face handle and a vector representing the offset. The face handle identifies the specific face on the mesh you want to modify, and the vector specifies the amount of offset in the texture coordinates.
Here is how you can call this method:
PolygonMesh mesh = new PolygonMesh();
HalfEdgeMesh.FaceHandle faceHandle = ...; // Obtain the face handle
Vector2 offset = new Vector2(0.1f, 0.2f); // Define the texture offset
mesh.SetTextureOffset(faceHandle, offset);Ensure that the face handle is valid and corresponds to a face in the mesh. The offset vector should be defined in the range that makes sense for your texture mapping requirements.
// Example of setting a texture offset for a face in a polygon mesh PolygonMesh mesh = new PolygonMesh(); HalfEdgeMesh.FaceHandle faceHandle = mesh.FaceHandleFromIndex(0); // Get the first face handle Vector2 offset = new Vector2(0.1f, 0.2f); // Define the texture offset mesh.SetTextureOffset(faceHandle, offset);
