Vector graphics programming

If you''ve got a DirectX SDK, look at the documentation on Direct3D Immediate Mode. It should have tutorials and samples. If you want 2D vector graphics, use D3DLTVERTEX as the vertex-type and set the z-coordinate to something neutral like 0.5

What are you talking about????!!!!! Me no understand de lingo ;-)

I need a tutorial on 2D Vector graphics programming. Not just how to do it, but terms and such like. Very, very basic. It''s nothing to do with Direct3D is it?

Hate to break the news to you, but unless you''ve got some custom hardware, you can''t do real vector graphics on your PC. By definition, you''re dealing with raster hardware (ie, pixels). Vector graphics implies hardware which draws lines explicitly on the picture tube.

However, you _can_ simulate vector graphics by simply using lines to draw your objecs with. Take a triangle, draw its outline, and voila, almost-vector-graphics.

Oh bugger. Well, if I was to do that then how do you work out collisions? If I plot two points and draw a line between them (and that line moves around the screen) how do I work out if a sprite hits the line? BTW - I''m totally useless at maths.

I have the same problem, I would like to do something similar to Flash or Illustrator graphics but in a DirectX game. Where can I find info about how to transform curve equations into anti-alised, good looking shapes on the screen ? Direct3D is not what I call vector graphics...

Most 3d graphics books have large sections on various types of splines. I highly recommend "3D Computer Graphics" by Watt, or good old Foley and van Dam. To get curves onscreen typically what you do is make yourself a spline and connect a bunch of lines along the length of it, subdividing until you get the required curviness.

That would be Computer Graphics: Principles and Practice by Foley, van Dam, Feiner & Hughes. I would certainly second that motion.
