Hidden Surfaces

Hidden Surfaces. Chapter 10. Hidden Lines. Hidden Lines Removed. Hidden Surfaces Removed. Why?. We must determine what is visible within a scene from a chosen viewing position For 3D worlds this is known as visible surface detection or hidden surface elimination. Hidden Surface Removal.

Zakrite ploskve

Zakrite ploskve. Problem outline. Given a set of 3D objects and a viewing specification, we wish to determine which lines or surfaces are visible, so that we do not needlessly calculate and draw surfces, which will not ultimately be seen by the viewer, or which might confuse the viewer.

Hidden surface removal

Hidden surface removal. Clipping algorithms will discard objects or parts of objects that are outside of the viewing volume But, that does not solve the problem of one objects blocking the view of another object Hidden surface algorithms deal with this problem
