Floating volume-of-interest in multilayer volume ray casting
A method that includes receiving vertices of a mesh, wherein the mesh represents a volume of interest (VOI) from an original volume, performing a transformation operation on the mesh, wherein the transformation operation transforms vertices of the mesh, obtaining sampling locations of the original volume using the transformed vertices, performing an inverse transformation on the transformed vertices of the mesh and the sampling locations, and performing a ray casting on the original volume to produce an image, wherein the ray casting uses the transformed vertices and a result of the inverse transformation as input.
