The scan line approach allows one to insert a arbitrary scan line within the lowest Y,Highest Y range onto the scan line statck and Angus vatti allows one to easily terminate the rendering at any scan line.I want to eval the area between any 2 scan lines LSLy ,HSLy.Do I have to do the clipping 2 times? for the 'Lowest' scan line to LSLy andthne repeat again for HSLy .I am NOT intersested in the Area coverage beyond the 2 scan Lines as above.!
I have a vatti/alike which allows me to do that for alternate(odd-even) parity.How do I that easily for Non zero winding?.
