Aligning one plane to another is a common task in 3D modeling. The easiest way to align planes is by using their normal vectors – we need to rotate the original plane so that its normal vector coincides with the normal vector of the plane for which the alignment is performed. Therefore, the task of rotating one plane to another can be reduced to the problem of rotating the normal vector of the first place to the normal vector of the second plane.

For ease of display, all input and output sockets on nodes, both shader and geometry, can be hidden from the user. Hiding unused node inputs and outputs may be necessary to simplify the visual perception of the node tree, which can be very large and complex and does not need to be overloaded with unnecessary information.

One of the methods for mesh analytics is exploring its triangulated geometry. For example, such exploration is used when searching for polygons that overlaps in the mesh itself or in its UV. In order to return the result obtained after analyzing the triangulated mesh back to the original mesh, we need to know the exact correspondence between the original polygon and the triangles created from it.
