## Re: [Algorithms] Draw & fill regular polygon?

 Re: [Algorithms] Draw & fill regular polygon? From: Graham Rhodes ARA/SED - 2011-08-10 15:29:37 ```Some helpful Google search terms are "polygon rasterization" and "polygon scan conversion." Someone else mentioned the Foley/van Dam book/et al. book, which is a good reference that describes the classic algorithm. The book Graphics Gems I also has a discussion, though it is brief. You can also find this stuff online, for free. For example, two sets of lecture slides from University of Virginia that look good: http://www.cs.virginia.edu/~gfx/courses/2004/Intro.Fall.04/handouts/11-polyscan.pdf http://www.cs.virginia.edu/~asb/teaching/cs445-fall06/slides/09-rasterization.ppt I even found this YouTube video: http://www.youtube.com/watch?v=TNbkX5bYrtE Graham -----Original Message----- From: Joel B [mailto:onephatcat@...] Sent: Wednesday, August 10, 2011 7:49 AM To: Game Development Algorithms Subject: [Algorithms] Draw & fill regular polygon? I should know how to do this, but i don't. I only have the ability in my system to draw lines (x1,y1,x2,y2)' to a bitmap, or write to the bitmap as a byte array. Can someone tell me the stepwise procedure to draw a polygon of n sides and then fill it? Having trouble finding anything online that doesn't use pre-existing primitives or libraries.
