So beautifull !
Thanks for this amazing/original work, we love it so much, incredible performance
Thanks again !

Just curious to know.. can it be used to make objects move along the spline and with relative rotations?

Solid gold.
Pretty damn awe inspiring codework... FPS is through the roof.

Any GM plans beyond this?

Can I ask how you're handling the rounded edges and antialiasing?

I've been toying with doing similar stuff in pixel shaders, never really figured out a good way to have smooth transitions between segments.

Oops, only just noticed your post. But the extension doesn't do any of that? If you're looking at the "how to use" images I'm afraid I drew them in a paint program, haha.

The extension is only for drawing. GM's path functions have spline support in the form of the 'smooth' option. You can determine the direction with point_direction(xprevious,yprevious,x,y).

I actually looked at this a long time ago, but now decided to praise you.
Really nice work. I was amazed about the example as it was so unexpectedly beautiful and fast considering GM is drawing it. Getting points on the curve is actually quite useful feature, but it possibly could be pain in the ass to find the point on a ds curve.
I was actually inspired by this to make these functions. But I would want to know how did you make the continues curve with the d3d_bezier_begin function? Does it actually draw a Bezier or some spline with Hermite (or other) interpolation? You already have a spline_begin function so I guess it really draws a Bezier, but then what order curve is it? I actually haven't tested the bezier_begin function so I should probably do that.
Anyway, really nice work.

Nothing that nice I'm afraid! Those functions exist only because of GM's limit of ten arguments. They only draw single quadratic/cubic beziers, selecting which to use based on the number of points given. They ignore anything higher.

And thanks.

Very nice, does this involve anti-aliasing in any way?

Hello,
First I want to say great job. Its very usefull.

But also it seems to be small problem in GM8.1 under Windows 7 (under XP seems to work fine).
I start app run then exit and I got message that application crashed.

Everything is saving before app crash so this is not critical.

This uses GMApi for calling GM's built in drawing functions. GMApi is not supported in 8.1 so it crashes.

Judging from the screenshots this looks like it can be used for a lot of fun stuff! Great work. I doubt I'll have the time to play with it more seriously, but it rocks no less!

[Master Xilo]

The demo is beautiful. Very well done!

It would be useful if you added a little help file to the extension. Or at least a link to this topic (by including an .url file (created by right clicking - create new link...) instead of a help file) (yes this works, I just tested it, you just have to manually start typing the name of the link file when including it as its not shown even with "All Files" selected).

May I suggest a draw_pie function with the same parameters as draw_arc? I made one myself but I draw a lot of them quite often so I was hoping there was a similar way to make it faster as you've done with all of these.

[grugin]

a new GMApi is available to gamemaker 8.1. There is a chance to see your great extension ported over gm8.1 ??? Thanks in advance.

[Monstr Gaming]

This isn't working for me.
I tried redownloading example but it still does not work.

It technically works but will not create any curves/splines/whatever like in the screenshots
any suggestions?
