Hi, all
How i can apply shadow texture for object's native state? I don't want modify
osg's sources (native shaders). I implement shader for multitexture terrain +
grass and other objects, and i want get shadow map and bind it to my shaders.
Now i implement like this:
Code:
class TestDrawCallback: public osg::Drawable::DrawCallback
{
public:
TestDrawCallback()
{
isFirst = true;
}
virtual void drawImplementation(osg::RenderInfo& renderInfo,const
osg::Drawable* drawable) const
{
osg::State* state = renderInfo.getState();
const osg::StateSet* stateset =
state->getStateSetStack().back();
osg::StateSet* ownStateSet =
const_cast<osg::StateSet*>(drawable->getStateSet());
osg::Texture2D* tex =
const_cast<osg::Texture2D*>(dynamic_cast<const
osg::Texture2D*>(stateset->getTextureAttribute(1,
osg::StateAttribute::TEXTURE)));
if(tex)
{
if(isFirst)
{
ownStateSet->setTextureAttributeAndModes(2,
tex, osg::StateAttribute::ON);
isFirst = false;
}
state->pushStateSet(ownStateSet);
state->applyTextureAttribute(2, tex);
drawable->drawImplementation(renderInfo);
state->popStateSet();
}else
{
drawable->drawImplementation(renderInfo);
}
}
private:
mutable bool isFirst;
};
I tested this texture map as base texture. The object which I rendered was
white, that is, texture is not passed on or something like that.
I
Thank you!
