Hi,
I am working with the method, findUnit(), within the class Processor and I have
come across something very strange:
In the program, osgppu.cpp using the header hdrppu.h, I do the following in
osgppu.cpp/Viewer::initialize():
Code:
mHDRSetup.createHDRPipeline(mProcessor.get(), firstUnit, lastUnit);
mProcessor->addChild(firstUnit);
osgPPU::UnitBypass* ppuUnit =
dynamic_cast<osgPPU::UnitBypass*>(mProcessor->findUnit("HDRBypass"));
osgPPU::UnitBypass* ppuUnit2 =
dynamic_cast<osgPPU::UnitBypass*>(getProcessor()->findUnit("HDRBypass"));
findUnit() in both cases returns NULL or 0 but I know for a fact that the
firstUnit is the "HDRBypass" Unit or UnitBypass with the name "HDRBypass".
However, when I issue this same findUnit command for this same unit within the
KeyboardEventHandler::handle() method, it works. Here is my code snippet:
Code:
osgPPU::UnitTexture* ppu =
dynamic_cast<osgPPU::UnitTexture*>(viewer->getProcessor()->findUnit("TextureUnit"));
osgPPU::UnitText* textppu =
dynamic_cast<osgPPU::UnitText*>(viewer->getProcessor()->findUnit("TextPPU"));
osgPPU::UnitInOut* pip =
dynamic_cast<osgPPU::UnitInOut*>(viewer->getProcessor()->findUnit("PictureInPicturePPU"));
osgPPU::UnitBypass* ppuUnit =
dynamic_cast<osgPPU::UnitBypass*>(viewer->getProcessor()->findUnit("HDRBypass"));
Does anyone know why this is the case? There is no documentation on this
anomaly and I need findUnit to work in my 1st case as well as the second case.
Thank you!
Cheers,
Allen
