VPR added to Graphics32

Two of my favourite graphics libraries have been merged together. The Vector Polygon Rasteriser (VPR), a very fast polygon scanline converter, has been merged into Graphics32, the software rendering library I used for the display rendering in the Woodland Calculator project.

The old polygon rendering code has been completely replaced and the results are very interesting. The rendering performance is slightly reduced compared with theĀ original fixed point base code, but it is faster than the old floating point, high quality code; whilst managing to produce equally impressive results. In fact, it can perform some tasks, such as rendering thick outlines, much more easily than in the prior version.

New Renderer

If you would like to see the difference for yourself, you can download the new WoodlandCalc.exe from SourceForge and compare it with the previous one also on SourceForge.
