I request new features that reduce aliasing/rouph edges be implemented. I noticed the aliasing was apperant no matter how good the hardware.

Hi Vox,

A question: why do you want to have anti-aliasing in a modeler? Of course your final rendering application (game engine, raytracer, render, etc.) may implement any anti-aliasing scheme you desire, but does it really aid in the modeling process?

FSAA and the likes are not terribly complicated to implement, but I don't think I've ever seen them in any modeling application, and I'd never considered it important, at all. If you (or anyone else) could provide us with some reasons why it is, that would be great!

AC3D provides an anti-aliasing option for its 3D viewport.
It just helps to have better screenshots, if for some reasons you don't want to render your model in your favorite raytracer ...
It's a good option, but of course a minor one.

Just my 2 cents Smile

If you have an nvidia card you can make custom settings for DeleD and turn up the AA when it's running. I don't know what that will do to the 3d viewports though.

I think that the ATI cards control panel also provides what you're talking about. But it's better to have that option inside the app itself, an option that you can check or uncheck as you want.
I only use the AA in AC3D for clean screenshots, otherwise it slows down my work too much.

I must say that I've never been bothered by any aliasing effect in DeleD.
Probably because what we usually do here are very low poly things (?).

The DeleD built-in screenshot system already supports anti-aliasing through 3x3 supersampling, no real need for FSAA there (unless you like the AA scheme your graphic card vendor offers better than ours, of course Very Happy). But I can understand it might a bit more pleasing on the eyes, and if you are not targeting aliased render solutions anyway, I can see how you would enjoy not seeing those pixelated edges ever again.

AFAICR, it used to be that the big difference between Quadro and GeForce cards was that the former accelerated anti-aliased lines, and the latter didn't. The reason being that AutoCAD, 3dsmax, Maya and the like use anti-aliased lines for geometry to look better for the artists.

Ah cool, I didn't know that. But anti-aliased lines != full anti-aliasing (!= polygon smoothing, which is not an option)... I know you know all that, just trying to sum up the options here... Smile
