Abstract
Method and device to visualize a composition of two matched surface models (M1) and (M2) in order to privilege the visualization of the silhouette of the second representation (R2) of the second surface model (M2), that is, the surface elements which are the most tangent to the viewing direction defined by the optical center (C) of a virtual camera and the point (P) of the surface of the second surface model (M2) considered, and to visualize it by transparency on top of the first surface model (M1). The disclosure is intended in particular to compare anatomical subjects before and after simulation or surgical or aesthetic procedures.
Claims13
A method to represent via a virtual camera (C) at least two surface models (M1) and (M2) in three dimensions, corresponding to the surfaces of a subject (S) wherein:
- the first surface model (M1) is represented via a first conventional rendering method (R1), and
- the second surface model (M2) is represented via a second rendering method (R2) privileging for its intensity parts of the second surface model (M2) whose surface normals are perpendicular to the viewing direction, and
- the two rendering (R1) and (R2) are merged using a merging function (MER) in order to provide a comprehensive representation (R12) with a single image of the two surface models (M1) and (M2).
