Ray Tracing - Polygon Rendering & Ray Tracing Methods
Ray tracing obeys all rays from the eye of the viewer back to the light sources. The method Ray tracing is very good at simulating specular transparency and reflections, as the rays which are traced via the scenes can be simply bounced at mirrors and refracted via transparent objects. We will discuss these concepts Refraction or Reflection/ transparency while we reach the section of ray-tracking.
Horizontal Retrace - Hardware Primitives Horizontal retrace refers to the time an electron beam takes to traverse a scan line.Vertical retrace means the time taken by the elect
