With the last version it's different, the fractal picture disappear and i get only a white square :

Hello Cyrille, Here a problem on PowerBook G4, MacOSX.4.11, GeForce FX Go5200 :

I will try on MacBookPro later. ++

hello,
http://techreport.com/discussions.x/8872
look like it's not possible with your hardware to get this patch working at full speed.
could anyone else test this patch please?

cyrille, I am using a variation of your patch to get my vertex morphing working. is just need to figure out a way to save 3d objects as rgb images... marius.

hello,
the good new is that things still can work as it was. just replace rgb32 with rgb. the old version does not use the same primitive, so i's possible there is more vertex now. this can explain the 70->130% diference.
we can investigate, i am not sure your card is able to use this acceleration.
with a nvidia 7700, this patch use only few %, so the change is really important!

hi, when I click on type byte, format rgb32 then I get this printout [gemframebuffer]: type is BYTE, 5121 [gemframebuffer]: format is GL_RGB_FLOAT32_ATI, 32992 but it starts eating up all my cpu. with the old version I cud run dim 512 512 at ~70% with the new version I am +130% this is on os x 10.5.2 with ati X1600. marius.

hello, i'm currently investigating the use of framebuffer to create a texture in order to use it as a vertex displacement. this has already been discuss in this list, but new stuff in framebuffer makes me try again.
i'm specially motived because it's the last things that prevent me trying physical modeling in glsl.
having a look at framebuffer, i noticed strange things : -changing type or format does not init the framebuffer, you have to change dim, or rectangle (mode) in order to init it. (i don't know why)
-in void gemframebuffer :: typeMess(char* type), should :
else if (!strcmp(type, "FLOAT")){ post("type is GL_FLOAT, %d",m_type); m_type = GL_FLOAT; return;be replaced by : else if (!strcmp(type, "FLOAT")){ m_type = GL_FLOAT; post("type is GL_FLOAT, %d",m_type); return; ??? (it's also the same in formatMess)
anyway. here are the good news : i add (and commit) a RGB32 format corresponding to m_internalformat = GL_RGB_FLOAT32_ATI; #ifdef __APPLE__ m_format = GL_BGR; #else m_format = GL_RGB; #endif (i don't know if apple definition is ok).
but the internal format GL_RGB_FLOAT32_ATI was mandatory in order to have an efficient implementation of vertex texture fetching.
so here is an example. it still need to be cleaned, but i'd like to know if it work on other computer. (here, it's about 50 time faster than previous example i send to this list)
please update/compile and test!
