Welcome to the osgPPU webpage

osgPPU is a library to use with  OpenSceneGraph. It provides you with a graph based specification of a computation pipeline. An example application shows how to setup true HDR Rendering with osgPPU.

Currently the osgPPU is in Beta phase. So I would be very appreciated on every input, like: critics, corrections, patches etc.

Features

• Supports multiple rendering targets (MRT) as output of ppu
• Can be also used for GPGPU
• Mipmapping on multipass is supported
• Use PostProcessUnitOutCapture? to capture frames in upto 4096x4096 resolution (or 8192x8192 on G80 GPUs)
• Example application describes how to implement HDR Rendering with osgPPU
• Supports Shader Model 3.0 and higher

In order to be able to compile the osgPPU you need latest version of  OpenSceneGraph.

Documentation

There exists a doxygen of the complete source code. You can find it  here

A first time osgPPU was presented as a part of a project at the  OpenSceneGraph BOF at Siggraph 2007 in San Diego, USA. You can download the presentation slides from  here.

Download

To get the latest revision of the source use following command:

svn co svn://projects.tevs.eu/osgPPU/trunk osgPPU

There is currently no stable release. Please use the source from the svn.

News

7th January 2008 osgPPU goes online

Today I was finally able to complete the code extraction of my previous application (refEiko) into a libray osgPPU. I have also created a simple example showing osgPPU in action. However there is a lot of work still to do to release first stable version.
