示例1: notifyMaterialRender
// this callback we will use to modify SSAO parameters
void notifyMaterialRender(Ogre::uint32 pass_id, Ogre::MaterialPtr &mat)
{
if (pass_id != 42) // not SSAO, return
return;
// this is the camera you're using
Ogre::Camera *cam = mInstance->getChain()->getViewport()->getCamera();
// calculate the far-top-right corner in view-space
Ogre::Vector3 farCorner = cam->getViewMatrix(true) * cam->getWorldSpaceCorners()[4];
// get the pass
Ogre::Pass *pass = mat->getBestTechnique()->getPass(0);
// get the vertex shader parameters
Ogre::GpuProgramParametersSharedPtr params = pass->getVertexProgramParameters();
// set the camera's far-top-right corner
if (params->_findNamedConstantDefinition("farCorner"))
params->setNamedConstant("farCorner", farCorner);
// get the fragment shader parameters
params = pass->getFragmentProgramParameters();
// set the projection matrix we need
