2d vector rasterization and transformations

| Hi all does anyone know where I can find some good information on this ? I used to have Tricks of the Windows Game programming gurus which had it all, but I dont have that book anymore and am battling to find info online about this. |

| Something like this? |
| ||
| as in drawing vector shapes and rotating them, scaling them etc... I would like to get to a point where I could do this in code and check for collisions between polygons. My math really stinks, I know in the book, he used matrices to transform the polygons. He had some serious collision detection too, to be able to check poly to poly collision. |

| I'm still working on poly to poly collisions myself. I *do* however have a rather spiffy little BMax Vector Graphics library cooking. You can find a demo here: http://www.codersworkshop.com/viewshowcase.php?id=802 |

| Poly to Poly collision? You must understand first the Method of Separation Axis. Heavy Stuff... I tried 3 or 4 times to convert the PolyColly but I had just done only the 2 first parts. Be sure to check it out. |
| ||
| A quick and dirty way would be to define a collision radius around the polygon and use A^2 = B^2 + C^2 to find the distance between polys. |
