osgNV-0.6.2

17th Dec 2008

• Add a new example osgnvcginkwash, which is contributed by a Chinese engineer Wei Ye and shows how to implement inkwash painting effect to models.
• Add a new osgNVPhysx library, which is going to support the nVIDIA physX physics engine step by step! Creation and computation of scenes and rigid actors are supported at present.
• Add a new example osgnvphysxboxes to demonstrate how to create a physics scene and dynamic boxes and do physics simulations using the osgNVPhysx library.

15th Dec 2008

• Resloved makefile problems when compiling debug libraries and examples.
• Add a new example osgnvcgbuffer to demonstrate how to use Cg buffer (introduced in Cg 2.0) to work with uniform values.

12th Dec 2008

• Added a new example osgnvcggeometry to demonstrate how to use gemetry shaders of new graphics systems.
• Modified headers and sources to fit the compiling on GNU/Linux.

11th Dec 2008

• Added new BufferParameterValue class for buffer parameters.
• Modified old examples and the reader/writer plugin to fit the changes.
• Modified Program and Context classes and add some functions for convenience.

10th Dec 2008

• Added new TextureParameterValue class for texture parameters.
• Added new ProgramManager class to slove the disable operations problems.
• Integrated parameter pointer functions to LocalParameter, using setUseParamPointer() to switch between parameter pointers and arrays, see applyVectorArrayValue() for details.
• VaryingParameter and CgGeometry are deleted because of the integration.
• Added setEnabled() to switch on/off the Cg program attribute.
• Modified CMakeLists.txt to move osgNVSLang and old examples to optional, and add a new example osgnvcgprograms, which demonstrates how to use Cg programs in different nodes, how to create callbacks for parameter animation, and how to use the new texture parameter class.

osgNV-CVS

13th May 2005

• Synchronized with latest OSG updates (pre-0.9.9)

10th March 2005

• Added preliminary support for osgIntrospection (limited to osgNV and osgNVCg namespaces for now)

16th February 2005

• Fixed a circular reference between osgNVCg::Context and osgNVCg::Program

12th October 2004

• Fixed return type of various getType() methods in classes derived from StateAttribute, to reflect changes made in OSG.

10th September 2004

• Added first iteration of GLSL support. You can now run GLSL shaders by using classes defined in the osgNVSlang module. See the new osgnvslang1 example.

6th September 2004

• Fixed a bug in osgNV::ParameterValue

28th August 2004

• Modified TimePicker so that it stores the last frame's time in the y component.
• Fixed a bug in osgnvcg4
• Added some #defines in osgNVExt/Extensions to support floating-point texture formats and PBuffer modes.

osgNV-0.6.0

17th August 2004

• Fixed compatibility with VC6

11st August 2004

• Improved the ParameterValue's "dirty state" mechanism. Now the actual check and reset of dirty states (based on change count) occur in the Parameter, not in the ParameterValue itself, so sharing a ParameterValue among different parameters becomes possible (out-of-the-box parameter value sharing).

10th August 2004

• The shader abstraction framework has been completely redesigned for flexibility and robustness.
• Moved all implementations of nVIDIA extensions (register combiners, vertex programs, etc.) to a new module/namespace: osgNVExt. Now the osgNV namespace contains only the base abstraction framework, with specific implementations being left to other modules.
• Added support for global (context-wise) parameters that can be bound to local parameters. This feature provides the means for sharing values and for implementing abstract interfaces (see Cg 1.2 docs for details).
• Added support for accessing struct fields and array items that belong to Cg parameters.
• Better multithreading support: now you should be able to run Cg-based applications on multipipe systems as long as you don't use pickers.

7th August 2004

• Modified ParameterBlock so that its getType() method returns an identifier which is different for each instance of the class. This makes ParameterBlock a "state attribute family" and prevents single instances from being overriden by subsequent ones in the scene graph.

6th August 2004

• Added support for "literal" program parameters in osgNVCg. See osgNVCg::Parameter::setVariability().
• Fixed a couple of minor bugs.

12th March 2004

• The code responsible for disabling profiles in osgNVCg::Context has been moved so that it is always executed before applying a context. This ensures that no spurious profiles are enabled when they should not be.
• Added an error callback to grab all errors generated by the Cg runtime and not only compile errors. See osgNVCg::setErrorCallbackEnabled().
• Updated descendants of StateAttribute to match recent changes in OSG.

23rd January 2004

• Fixed a bug in VectorPicker's I/O code

30th December 2003

• Fixed two bugs in osgNV::MatrixParameter, now it should behave correctly and send column-ordered matrices down to the GPU (you may notice that your matrices now get to the vertex program transposed, but you should also notice that OpenGL and Cg use postfix matrix multiplication while OSG uses prefix multiplication). Thanks Ruben for spotting this bug!

19th November 2003

• Added a demo application for osgNV::ParameterBlock.

31st October 2003

• Added code to display detailed error messages when a Cg program fails to compile. Minor fixes in osgNVCg::Context to prevent it from disabling unsupported profiles. In addition, supported profile names are now displayed when the context initializes (output to DEBUG_INFO).
• Added a new class: ParameterBlock which inherits from StateAttribute and allows to apply a set of parameters as a stand-alone unit to any part of the scene graph. With this class you can decouple the program from its parameters, improving flexibility.

osgNV-0.5.7

7th September 2003

• Added a new Cg example (osgnvcg4) to show how to use pickers
• Added ModelMatrixPicker class

30th July 2003

• Fixed some minor bugs in osgNV.
• Fixed a serious bug in osgNVCg which didn't manage state changes correctly.
• Added two picker classes: ViewMatrixPicker and EyePointPicker, with full I/O support.

26th June 2003

• Added I/O support for new "picker" classes: TimePicker and LightPicker

14th June 2003

• First implementation of a set of classes for picking attribute values from OSG objects (or from the current state) and automatically assigning them to parameters. Two classes have been implemented: TimePicker, which extracts the current time from a FrameStamp or from osg::State and puts it to a VectorHolder, and LightPicker which picks light properties and stores them into a VectorHolder. Several mapping combinations are possible via their base class, VectorPicker.
• A new non-trivial issue has been found: it seems that enabling a vector parameter at the same register address where a state matrix parameter were enabled before, it doesn't overwrite the previous matrix tracking. This could cause unwanted behaviours when you have two or more vertex program because matrix trackings will propagate through different programs.

10th May 2003

• Created a new class for parameter callbacks (ParameterCallback) which replaces the previous osgNV::Parameter::Callback class and inherits from osg::Object (so that dot_osg I/O is possible).

osgNV-0.5.6

26th March 2003

• Source code of demo applications has been moved from /src/Demos to /examples, for consistency with latest changes in OpenSceneGraph.

23rd March 2003

• The MatrixTracking class has been renamed to StateMatrixParameter for consistency with osgNVCg.
• I/O support for osgNVCg objects has been implemented.

22nd March 2003

• osgNVCg::UniformParameter has been splitted into several classes as for osgNV::VertexProgramData; all parameters that contain the same data type inherit from the same base class, so there is a common interface for assigning values to any parameter class that contains a particular type of data. Please note that the transition has not been completed yet, and the library can compile only on VS .NET now.

19th March 2003

• osgNV::VertexProgramData has been replaced by a set of classes that handle different types of data: VectorParameter, MatrixParameter and VectorArrayParameter; next step is to convert osgNVCg parameters to match this new structure. Once osgNV and osgNVCg parameters share a common structure, I'll implement a set of classes that will act like a glue between OSG objects and osgNV/Cg parameters.

18th March 2003

• Fixed a serious bug in osgNVCg::Context
• Converted all demos to use Producer instead of GLUT
• Added the applyWithoutCallback() method to osgNV::Parameter
• Added TEXTURE_0 ... TEXTURE_3 matrix types to osgNV::MatrixTracking
