Hey all,<br>
<br>
Quick question:<br>
<br>
In designing the rasterizer for the 2D mask editor, I see that I have<br>
a choice to make.<br>
<br>
Option-A.) I can rasterize any polygon whatsoever with a very<br>
straightforward method. No problems. (this is how it works right now)<br>
<br>
but...<br>
<br>
B.) If the polygon (the mask) edges only intersect any given scan line<br>
only twice (meaning enter poly... then leave poly... never re-enter<br>
poly on this scan line) then the polygon could be rasterized at higher<br>
speed. (can be implemented now, or added later, without<br>
<br>
so...<br>
<br>
Here is the question:<br>
<br>
It is worth a slight performance hit to TEST the mask for<br>
Option-B-Compliance, which if it DOES pass, makes it faster to draw,<br>
or just skip it since "most of the time" the mask will fail the<br>
Option-B-Compliance test anyway?<br>
<br>
Not being a VFX guy I can't really judge what the typical use case is...<br>
<br>
Any feedback would be welcome.<br>
<br>
Cheers!<br>
Peter<br>
