Abstract
The previous chapter introduced the concept of a virtual 3D world and showed how to generate wire-frame images of this world — the present chapter will build on this foundation to create images which contain polygons filled with solid colour. The line-drawing code of the previous chapter is used here to calculate the outline of a polygon — this outline can be filled with coloured pixels in an efficient manner. The essential topics include:
-
GDI polygon-fill functions
-
calculating a polygon outline
-
optimizing the colour-fill process
-
hidden polygon removal
-
storing a virtual world in a file
