WebThe goal of the project work is to develop an algorithm to implement NURBS in the existing ray tracing code. To achieve that, a NURBS data structure has been created and an algorithm to read the NURBS objects parameters from IGES files has been developed. Two methods for finding ray intersection on the NURBS surface have been developed and ...
