hidden surface
The Precise Rendering Method first solves the aliasing problems of hidden surface removal by using the Cross Scanline Algorithm.
      
A drawing speed of 8 ns/pixel (32 bits/pixel) or 1.2 million Phong-shaded polygons/s (100-pixel polygons, texture mapped with hidden surface removal) was achieved when 60-ns accesstime single port DRAMs and synchronous DRAMs were used.
      
A new efficient algorithm is presented which implements the hidden surface effect for synthetic image holograms.
      
An improved technique for output-sensitive hidden surface removal
      
We derive a new output-sensitive algorithm for hidden surface removal in a collection ofn triangles, viewed from a pointz such that they can be ordered in an acyclic fashion according to their nearness toz.
      
Our results include efficient algorithms for output-sensitive hidden surface removal, for ray shooting in two and three dimensions, and for constructing spanning trees with low stabbing number.
      
This has applications in hidden surface algorithms operating on polyhedral scenes and in cartography.
      
As an application of the method we obtain an output-sensitive method for hidden surface removal in a set ofn triangles that runs in timeO(nlogn+n·kγ) whereγ=log2((1+√5)/2) ≈ 0.695 andk is the size of the visibility map obtained.
