#5016499 Can't properly fill my polygon

use the scanline algorithm, it's alot faster than filling every triangle

yes this is correct, since dot product is distributive you can write t = dot(a-e.n) / dot(d,n)

#5010944 Software Renderer, silhouette refinement

Posted by on 15 December 2012 - 08:02 AM

hi, i'm working on an exercise for university and we are implementing a software renderer in java.
they want us to implement some cool stuff we want, and to play around with it

i thought about implementing silhouette refinement (just because i think it's interresting),
saw this here: http://www.youtube.com/watch?feature=player_detailpage&v=nMwk2Zi0c3o#t=39s

how would you implement this method? i googled around and found this: using some kind of adaptive tessaltion on the silhouette tris/edges

thought about implementing an own rasterizer and use polynomial curves instead of straight lines on the outer edges, could this work ^^?

pls throw in your ideas, and give me stuff to melt my brain :D

with kind regards, DDoS
