Can one add shaders to jit.gl model ( multiple models) that have textures applied.. ( in patch) also how do you get the parameters for the shaders included with jitter so they can be applied to models.

My approach would be to load the model and do a @matrixoutput 1, then send it to a mesh where i would apply the shader.

The textures is GLSL are made by using a series of Built-in types:

Shaders communicate with the application by the use of 'uniforms' where you can provide a numerical value to the parameters you declare on your jxs file.

Shaders are extremely flexible: you can modify a texture projected on a video plane(jit.gl.slab) or modify the vertex position of a geometry. It depends on what you want to do.Maybe you should take a look here, super nice tutorial by one of the jitter gurus, Andrew Benson,:

There are different ways to do this.

sampler2DRect texture2DRect
sampler2D texture2D
remember to declare them as 'int'!

got that..( Thanks had looked before but didn't sink in) and am able to shade models and effect geometry but not at same time

and don't seem to be able to use Shaders when also texturing models . the shader seems to override the texture.. and when geometry shader is used everything flattens out. seems to be a priority issue..but not sure of structure

shaders generally make use of the textures.

but yes, if you bind a gl object to a texture and a shader, and the shader ignores the texture, then the texture will not be displayed.

I have been able to get shaders to work with my models but as I am texturing them with movies and live video when I apply the shader my textures are ignored .. can shaders be applied to the whole output including my textures .. or is it impossible ? have looked at Vades shaders for models and got some working with my models but the textures are ignored.. I am guessing the shader binds like a texture and you can only use one texture at a time on a model. I'm thinking there must be a work around...any ideas?

You have to bind tex parameter (to 0 right awawy which means the first inlet of the slab), otherwise the texture will be ignored.

This should help you:
