Hi to all,
i'm trying to visualize the "depth field" effect in my osg application, using
shader (vertex and fragment) from this link
http://devmaster.net/posts/3021/shader-effects-depth-of-field
The vertex program, requires as uniform the following :
uniform mat4 ProjectionMatrix;
uniform mat4 ViewMatrix;
uniform mat4 ModelMatrix;
uniform vec3 ModelScale;
So, in my osg application, i suppose to pass :
myProgram->addShader(mVertexShader.get());
myProgram->addShader(mFragShader.get());
mStateset = mMyModel3D->getOrCreateStateSet();
mStateset->setTextureAttributeAndModes(new osg::Uniform( "ProjectionMatrix",
myCamera->getProjectionMatrix() ));
mStateset->setTextureAttributeAndModes( new osg::Uniform("ViewMatrix",
myCamera->getViewMatrix() ));
mStateset->setAttributeAndModes(mProgram.get());
...
Does it correct?
How can i pass also mat4 ModelMatrix and vec3 ModelScale?
mStateset->addUniform( new osg::Uniform("ModelMatrix",??? ) );
mStateset->addUniform( new osg::Uniform("ModelScale",
myMatrixTransformObject->getMatrix().getScale() ) ); // ???
Thank you!
Cheers,
Andrea
