how to amend coarse edges
May 24th, 2005, 8:54pm  
i've been using 0068 alpha. Today is the first time i tried the new version. I altered an old sketch a little to suit the new version. But, the effect in 0090 beta turns to be awful.

It is very clear taht the edges in 0090 are more coarse. Any one could tell me anything i have missed?

Are you using P3D or OPENGL?

If OPENGL, try smooth();

Also, the other version has shading, so try adding lights();

(I don't know if this is of any help, but anyway...)

yeah, it turns out that solving the issue of lines vs. filled 3D shapes is almost impossible. in alpha, there was a hack that was drawing lines slightly in front of things, but that was a disaster because no matter what you drew afterwards (i.e. if you were in 2D), the lines would still be on top. no good.

so we sort of gave up on fighting with it. we have one idea about how to deal with it, but it'd be really slow.. but looking at more "profesional" libraries than processing, like opengl, which are written by people smarter than i, they haven't solved it either, so it doesn't bode well.

oh, but you also need to turn on lights(), yes.. that'll give you the shading. and if the shading is different in the old version, it's because the old version was actually wrong, but the new one is correct.

Lines and 3D shapes don't blend well anyway, just look at the current hype (reasonably current at least) about toon- or cell-shading. Even heavy-duty rendering software like 3D Studio Max doesn't have these features by default.

Thank lunetta, i was originally using P3D, and i tried opengl as u told me. Smooth() which could not be used in p3d, works in opengl and the edges look better now. But the zoom function of OCD went wrong in OPENGL, but anyway, that's not crucial.

Thank fry too. I could understand the dilemma. U 've done ur very very best~~   We all pay high tribute to ur great job. ^^
