osgPPU v0.4 tagged

Hi folks,

i've just tagged v0.4 of osgPPU (post processing NodeKit? for OpenSceneGraph). The new version does support:

- full support for osg 2.8
- New Modules:
-- UnitInOutModule? processing units can now be loaded from .so/.dll modules
-- UnitCamera? - bring additional cameras into the osgppu pipeline (usefull for multiple cameras being processed by osgPPU)
-- UnitCameraAttachmentBypass? - put any camera attachment into the pipeline (depth buffer, color buffer, stencil, ...)
- deprecated class "Shader" removed (use ShaderAttribute? instead)
- small build fixes (changed Cmake files)
- examples do build now with osgppu_ prefix
- support for .so version build extensions (i.e. libosgPPU.so.0.4.0)
- new examples:
-- ssao - simple screen space ambient occlusion
-- glow - simple example shows how to use osgPPU to let certain objects glow)
-- cuda - shows how to compile and use CUDA kernels together in ppu pipeline
-- CUDA support - bring cuda kernels into osgPPU pipeline, by loading CUDA-kernel through UnitInOutModule? unit (CUDA kernels has to be compiled externally into an .so/.dll file)
- full support of "NodeKit?" definition

Take a look, if you are interested.

Arbitrary symbols enforce consensus of <a href="http://www.businesshostingprovider.com">cheap web hosting</a> perceptions, which not only allows members to communicate about the same objects in terms of space and time <a href="http://www.businesshostingprovider.com/dedicated-server.htm">dedicated servers</a>(as in hunting) but it also makes it possible for social relationships to be standardized and manipulated through symbols. It means that idiosyncracies are smoothed out and <a href="http://www.businesshostingprovider.com/isp/wireless-internet.htm">wireless internet</a> perceived within classes of behavior. By enforcing perceptual invariance, symbols also enforce social behavioral constancy, and enforcing social behavioral constancy is a prerequisite to differential task-role sectors in a differentiated social group adapting not only to the outside environment but to <a href="http://www.businesshostingprovider.com/vps-hosting.htm">vps hosting</a> its own membership.

  • Very usefull also for GPGPU (general purpose GPU) computations
  • Supports multiple rendering targets (MRT) as output of ppu
  • Supports multiple inputs to a ppu
  • Supports out of the pipeline texture inputs to a ppu
  • Mipmapping supported
  • Use UnitOutCapture? to capture frames in upto 4096x4096 resolution (or 8192x8192 on G80 GPUs)
  • Use osgdb_ppu Plugin to load and to store the pipeline from and to the file
  • Example application describes how to implement state of the art effects like HDR Rendering or DepthOfField? with osgPPU
  • A lot of example pipelines (hdr, dof, motionblur, ssao, glow ...) are provided as .ppu files
