[osg-users] how to add shader to osgcal node

[yang zhiyuan]

Hi:

    I am trying to add shader to osgcal node.

    I do it like this:

  

   osgCal::CoreModel *core = new osgCal::CoreModel("dummy");
 load(core); //< loading some data into it
 // Creating a concrete model using the core template

 osgCal::Model *model = new osgCal::Model();
 model->create(core);

 osgCal::Model *model_2 = new osgCal::Model();
 model_2->create(core);

 //osgCal::Model *model = new osgCal::Model(core);

 // Setting the first animation in loop mode, weight 1, and starting just now
 model->startLoop(0, 1.0f, 0.0f);
 model_2->startLoop(1, 1.0f, 0.0f);

 model_2->setTimeScale(1.5f);

 osg::ref_ptr<osg::Group> escena = new osg::Group();
 escena->addChild(model);
 escena->addChild(model_2);

osg::StateSet* stateSet = escena->getOrCreateStateSet();

osg::Program* program= new osg::Program;

osg::Shader*   shader = new osg::Shader(osg::Shader::VETEXT);

.......

 

the problem is the shander does not apply to the osg node,is there any other way to add shader to osgcal node?

A problem you'll have is that the osgcal model has it's own shaders applied
down at the geometry level. These will override the one's you are applying
further up the graph.

Hi:

model_2->setTimeScale(1.5f);
