hi list
i found this picture http://daimi.au.dk/~vectral/html_gallery_1/pics/Image_00227.jpg which is done in max/jitter on osx and i wonder how do you get them "soft" edges/lines on them "boxes", if its possible at all. when I create a cube or any other 3d object it has that "grainy" look. Does it have anything to do with the OS/hardware its been running on?
best regards ./jc
hello, if you use a nvidia GPU, you can set antialiasing on the rendering using a FSAA message to gemwin (see gemwin help), before window creation. if you use nvidia or amd gpu, you can force the antialiasing using drivers configuration tools (if available on your os) whatever gpu you are using, you can set per primitive antialiasing using the polygon_smooth object after a gemhead
on my experience, this last option can be slower than the 1st one.

hi Cyrille and list
yes i found some configuration tools and maxed them up and yes i can see the smoothing now (which still is grainy, but its ok), but it seems like polygon_smooth does nothing. i have no nvidia gpu, so no FSAA for me (but something called ati radeon express m200 from somewhere 2006 on this win box). i guess so far i will be left in a dust (of smoothly rendered boxes), until i'll buy an nvidia gpu. Can anyone advise an nvidia gpu (or some tech specifications) which will be powerfull enough to render the edges as smoothly (cirka) as on that picture, i linked. thank you for very fast reply best regs ./jc

any nvidia gpu will do antialiasing with no problem. but if you wish to render 10000 big square, you probably need something a bit better than the cheapest GPU available.

hi
thank you for the advise. I think I'll go practicing and experimenting on "boxes" before I figure what gpu I want to invest in. If its not too confidential, may I ask you to share your systems (OS/hardware) specs, when you are working/performing with Gem.

I use linux. in this OS, driver is more a problem than hardware. so i used Nvidia because that was the only one that provide good driver (proprietary).
2 years ago, i was not able to choose the computer to use for a performance, so i had to use a ADM GPU. Driver did improve a lot and things where usable. i did not try since.
since few years, nvidia had the optimus system for laptop that allow 2 GPU: intel and nvidia to work on the same time. The intel GPU is for everyday use, the nvidia for graphical demanding application. No real good drivers allow to use this on linux. So most of the time the nvidia is slower than the intel.
So i've got a optimus latop. I use the intel gpu most of the time for Gem. Even for performances. but sometimes it's good to have the nvidia, for testing, and for non real time rendering.
So, looking only at the hardware : nvidia and amd build low / medium and high end GPU. intel did only do low end gpu. but i'm still surprised by my intel HD4000 : working with shader, it's lot's faster than the mid range nvidia i used 3 years ago.
hope that help

it does help indeed, big thanks for the reply i also use linux, but on a another box (with intel gma something stoneage) which i optimized strictly for sound. so i borrowed this box to play around with. Does anyone know how are the ati drivers with linux/GEM combination? best ./jc

obviously, you have to insert [polygon_smooth] *before* your Geos (e.g. your boxes). less obviously, you also might want to insert [alpha].

damned! i forget the alpha! thanks
