Hello Guy,
If you set different shader for each object, I would like some
clarification about your original question.
Yes this is that what i would have, sorry for my confused description.
Do you want different shader per object but with some common features
that are different for each view??
Ok, lets have some theoretical example, shall we...
Suppose the scene is composed of:
- 3 views.
- 2 parameters which are view dependent, named Param1 and Param2.
- 3 objects with different shader for each.
Now, we must have some assumption:
- You have access to the shaders code, and you are
Hi folks,
actually i am working on object shading with OSG (i.e. Dot3). All works fine
with single views. Now i am using the osgViewer::Composite viewer and getting
some dielemma with the usage of object based shaders in differend views based
on the same scene graph.
I.e.: I've a single scene
Hello,
I think attaching a shader to each view instead of to object X would be
fine.
If you want to use the callback I think you should create a pre-draw
callback to the object, which I'm not sure possible. The update
callbacks won't help you since it run on all the scene before the
rendering
Hello Guy,

I'm not sure if this may be the right thing. Correct me if I'm wrong but
this causes

Geometries etc. How

Well, the shader doesn't know of the stateset of the object (textures
attached) if you don't set it explicitly. Otherwise, the shader can be
inherited and at ObjectX you can add a uniform for the sampler.
You are right that all the objects will be rendered with the same
shader.
If you set
