Dear IUP List, I'd like to try my hand at making a vector drawing tool, from scratch. And I'd rather not have to invent the math and algorithms myself. Are there APIs in IUP and/or CD that make this easy? Or do I have to add my own code to answer queries like is point (x,y) close enough to that bezier curve to register a hit, on a mouse click? Is there a good book on the subjects I need? I've been flipping through the old Foley book, /Computer Graphics, Principles and Practice/ (1995) but it seems to be a bit high level for practitioners or I'm just lost in the math. Website resources would be cool too; I'm not a fan of videos. Thanks, Johann |

Hi, > Or do I have to add my own code to answer queries like is point (x,y) close enough to that bezier curve to register a hit, on a mouse click? CD does not have functions like that, it is a simple graphics library. Such questions don't usually be solved by graphics libraries. Foley is a great reference, Graphics Gems is another. I would search for algorithms and implement myself...
