Mentioned in lecture for context: the uv coordinate space here is mapped to the red and green color space, so we can better see how the model is projected onto 2D.

Haven't watched the Thursday lecture yet, but to form the triangles in the slide, after mapping / reverse mapping the coordinates between the two spaces, we'll possibly need to locate the triangles with these "important" points (triangle vertices) via triangulation methods such as Delaunay Triangulation, which is an efficient method to cut 2D-space regions into triangle pieces with pairs of matching points defined in advance. https://en.wikipedia.org/wiki/Delaunay_triangulation

Following from the previous, is the procedure consist of defining the pairs of points between 2D-3D, triangulating the 2D space, then using Barycentric coordinates to map the entire 2D image over the 3D model?
