by cyrille henry 18 Nov '09

18 Nov '09

hello, i've got a strange problem with pix_image with the latest Gem on ubuntu 9.10 (using Nvidia drivers) the pix_image object use lot's of CPU, event if no images are loader and if it is not connected to any other object. no gemwin created either. if i create a new patch, put 20 pix_image objects, my cpu go to 60%! anyone having this problem? any idea how to solve it? same gem version with ubuntu 8.10 works fine. thanks Cyrille

Depth Of Field
by Pierre 10 Nov '09

10 Nov '09

Hi, Something I would add to G.E.M. is the "Depth Of Field" effect. Someone asked this last year on pd-list without succes/response : http://lists.puredata.info/pipermail/pd-list/2008-10/065649.html Adding something like a 'focus' parameter to [gemwin] would be very nice. Maybe it could be done using GLSL or [GEMglAccum] (*) but, until now, all my searches and tests have failed... Any ideas on how to do that ? I can code a bit a opengl/c, but I have poor skills... So any help, link or idea is welcome ! Best regards, Pierre (*) http://www.opengl.org/sdk/docs/man/xhtml/glAccum.xml (*) http://www.opengl.org/resources/code/samples/redbook/dof.c

FTGL 2.1.3-rc5
by Hans-Christoph Steiner 04 Nov '09

04 Nov '09

So some other developers have released an updated version of FTGL. It seems like mostly they are updating the code to work with modern compilers and frameworks. http://sourceforge.net/projects/ftgl Any harm in updating it? .hc ---------------------------------------------------------------------------- "Free software means you control what your computer does.

hello, i've got some problem using pix_multiblog. it's on a mac osX 10.6. i'm using the lattest Gem from iem (0.92.1) (Gem is advertised to be 10.4 and 10.5, but i'm under 10.6) everything look like working ok, except pix_multiblob. it always output 8 blobs. they all move from right to left, but not on the Y axe Xmin is always 0, Ymin is almost 0 ; 2/15; 4/15 etc Xmax is always 0.996875, Ymax is almost : 2/15; 4/15; 6/15 etc does anyone have an idea? if it's a 10.6 problem, does anyone have a Gem build for 10.6? thanks Cyrille
