I am looking for an example of how to do multitextureing in jitter using jit.gl.shader objects rather than jit.gl.slab objects. My main problem is figureing out how to bind the set of textures properly. So far the only examples i could find that do multitexturing with shaders, is slab examples, but i am looking for jit.gl.shader example.

Code-wise, multitexturing is the same for both slab and shader. The

shader will have a tex0 and tex1 parameter that you bind to the

fragment program. However instead of sending a matrix or texture in

the 2 inlets of a slab, you simply make an ob3d with an array of

texture names like jit.gl.gridshape context @texture tex0 tex1 and

Bind the multiple textures using the target object. e.g. 

jit.gl.gridshape @shader shadername @texture tex1name tex2name 

For example jit.gl.slab is almost the same the following (you'll need 

to define the shader, texture input and texture output objects 

jit.gl.gridshape @shape plane @shader shadername @texture input_tex_1 

input_tex_2 @capture output_tex @reset_transform 2

Bind the multiple textures using the target object. e.g.  
jit.gl.gridshape @shader shadername @texture tex1name tex2name  
tex3name ...

For example jit.gl.slab is almost the same the following (you'll need  
to define the shader, texture input and texture output objects  
separately of course):

jit.gl.gridshape @shape plane @shader shadername @texture input_tex_1  
input_tex_2 @capture output_tex @reset_transform 2
