Re: Polygon Rendering Speed

Olaf,

An interesting proposition, but the polygons are not necessarily regular. If
indeed filling the RGB array of a DIB section is faster, I'm not sure on the
math required to locate all the pixels in such an array when I only know the
4 points (which are essentially arbitrary).

...Data consists of 4 sided polygons, of which a single bitmap
could contain around 140,000 polygons that average about
2x2 pixels in size.
...on the other side - the size of your Polygons seems very small
with only 2x2Pixels on average - I mean these are only 4 Pixels
to set.
Why not work on a DIBSection-mapped VB-Array and set
the Color-Values of those ca. 4 pixels in the Array directly
(at least for all the smaller Polygons)?

This could speed up your Polygon-Rendering by Factor 10 or so.
