Hi, I am using osgPPU (0.4.0) in a distributed environment and thus rely on the image readback functionality through camera attachments to be able to send rendered/postprocessed images over the network. Since OSG 3.0 seems to require the osgPPU trunk version and i could also use the new resize functionality of osgPPU i tried to migrate to the newer version. Unfortunately since the update i only get clear color read back instead of the UnitOut output. The updated API doc says that UnitOut disables the FBO which i am using, but switching the camera implementation from FBO to simple FB leads to the same results. Are there any other changes in that regard i need to be aware of? And what is the correct way to use UnitOut now if i want to use camera attachments?
Debug output looks ok, the only thing differing between 0.4.0 and trunk is the additional line "output: 0". According to the source this line was caught by an if-phrase before and thus omitted. PipelineResult is a UnitOut, color is a UnitTexture for input and BlurX an instance of UnitInOut: BEGIN FRAME EffectNode osgPPU::Processor color run in thread 0 vp 0x21300f0 (ref 0): 0 0 512 512 program: 0x212d4a0 input: 0:0x1f1c690-attr (512x512) output: 0x1f1c690 (512x512 ) BlurX run in thread 0 vp 0x3f4fbe0 (ref 0): 0 0 512 512 program: 0x7fa474019f10 radius : 15 sigma : 15 input: 0:0x1f1c690-attr (512x512) output: 0x3f50370 (512x512 ) PipelineResult run in thread 0 vp 0x3f51160 (ref 0): 0 0 512 512 program: 0x2130c80 input: 0:0x3f50370-attr (512x512) output: 0 END EffectNode osgPPU::Processor Regards, Luciano _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
