Hi, It seems like we cannot use two GLSL shader programs at a time. Hence, I need to merge both fragment and vertex programs to use them together.... Is there a way to use more than 2 shaders ? In Jitter, there is jit.gl.slab that allows that. http://www.cycling74.com/documentation/jit.gl.slab
If not possible in Gem, that would be an awesome add-on to it.
Hi alexandre, why do you think it is not possible? or what exacactly do you want to do? If you try to have several glsl programs like a filter bank, first do glsl-blur, then glsl-bloom, then glsl-apply-texture-to-model... then I think this only works with gemframebuffer plus playing around with "texunit 0", "texunit 1", and so on... and maybe also the right in/outlets of texture to reference gpu textures. unfortunately GEM on os x 10.5 is still broken, so I can only do very rudimentary stuff (no developing), but before that I was trying to do exactly this and I think it should be possible to do. marius.

I agree, this should be possible in theory. I suspect one should be
able to build an abstraction that would dynamically load a shader
program, render to a quad, send that quad to a texture and output the
texture.
This is basically all jit.gl.slab does for stream processing.
I still have heard nothing on the multitexture issue for GLSL however,
so there may be some gotchas.

What do you mean by a "quad" ? You mean to render it to a texture ? This would need to use something like pix_snap2tex ? (capturing the whole window render)

quad, as in 4 verts, as in a plane. Texture your quad, bind the quad
to the shader you want, render it the quad with bound texture and
shader to another texture (b), output the texture (b) to the next
effect in the chain.

in gem you can use
[gemhead] | | [dim 512 512( | / [gemframebuffer 49] | [translateXYZ 0 0 -4] (where are the properties for gemframebuffer???) | [pix_image] | [pix_texture] | [pix_square]
but I could not get this working for glsl_program. marius.

hello,
this is a big problem.
you could always use a pix_snap2text, but it's slower.

that is what gemframebuffer should do. render a gemchain into a texture on the graphics card. but as I mentioned in my mail before, it does not work with glsl_program. marius.
