I get good results here with this method, better than render 4 times a primitive and translate it by 1/2 pixel with alpha. Maybe it depends on what you need to render ? quality depend on what you need to render, but usually polygon smooth is better. but performance depend on the GPU : nvidia have good antialisaing performance. i don't know about AMD. for intel, rendering 4 time gives better performances with acceptable quality. cheers c Thanks to this info, my computer will be cooler :) ++ Jack ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
[PD] Gem High def out put (stills ect)
Hi II am use Gem to create some 3d artworks I planning to have printed for framing/postcards etc.- would be grateful for any advice on way to save high quality/large images from the Gem window? Ways to achieve Anti aliasing (is this only for Nvidia graphics?), smoothing of edges and such. Thanks for the advice all, much appreciated.

Alan ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list Hello Alan, Have a look in examples section in Gem (from the help panel). There is '02.advanced/09.SnapshotSaveHD.pd'. There is no Anti aliasing, but after you can reduce the size of the picture with a software like Gimp to get something smooth. Or it is possible to use supersampling anti aliasing with two or more framebuffer, but you need a good graphic card for that. Hope '09.SnapshotSaveHD.pd' will work for you. ++ Jack ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

hello, rendering to a framebuffer allow 4096 or 8192 (depending on your hadware memory) pixel snap. you can render only part of the image in the framebuffer using the perspect message to gemwin, in order to add many of them to a bigger image. for antialiasing, you have many solutions depending on what you are rendering - the easiest is to insert alpha and polygon_smooth object after the gemhead. - an other one is to render 4 time every primitives translated by a 1/2 pixel on every direction, and using alpha to adjust transparency. - you can render a very big image and reduce it. cheers c Le 11/04/2013 14:30, Alan Brooker a écrit : Hi II am use Gem to create some 3d artworks I planning to have printed for framing/postcards etc.- would be grateful for any advice on way to save high quality/large images from the Gem window?

Re: [PD] Gem High def out put (stills ect)
Thanks everyone for the suggestions [polygon_smooth] helps much. 09.SnapshotSaveHD looks like it could be what I need but it has me a bit stumped. I will try to connect it into my Gem scene but any tips would be welcome Thanks again for the feedback!
