Rounded corner

Hi Everyone.

Let's say I have an array of coordinates used to describe a polygon. I would like to be able to rewrite this array with more detail so I can add rounded corners. (for example, a corner could consist of 8 coordinates instead of the original 1 and so the array would go from holding 4 coords to 32). I would supply the radius of the rounding as well.

Is this called anything in particular so I can read up on it? Or even better, has anyone done something similar?

Ta!

I would use a list for that. If you're set on using arrays then check Slicing to resize the array dynamically.

Cheers tony, the actual storage of the information wasn't the problem (well it isnt yet ;) It's more the working out of the coordinates. Like, I know the red coords, I know the radius of the circle and I would like it to work out the green coords.



So the function would be something like

function roundCorner(x1#, y1#, x2#, y2#, x3#, y3#, radius#, detail:int)

where detail specifies how many coords to return.

However, I think I should be able to do it once I work out the center of the circle coords and where the circle hits each line. I can work out the circle position by working out where two lines parallel to the original lines cross.



There's some code in the archives that tells you where a line intersects a circle as well, so I'll have a closer look at that and should be sorted :D

Huzzah!
