79cb22eb06 Changed the view movement detection code so that it uses the
new CullVisitor::Identifier to indentifier cull traversals,
this enables the code to properly detect movement when
osgViewer::Renderer uses double buffering of SceneView.

307bf7002f First cut at LOD support in RayTracedTechnique, which lowers the number of samples taken when the view of the volume is changing. 2011-03-17 11:49:22 +00:00

d3d0859b4c From Piotr Gwiazdowski, "So there's config setting OSG_DISABLE_MSVC_WARNINGS which should
disable pragmas that turn off specific warnings for MSVC.
Unfortunately it's presence is only checked in osg/Export header,
making other Export headers disable warnings no matter what, which is
kind of incoherent.

My fix adds #include <osg/Config> to every Export header. I've also
unified checking whether to disable warnings to current osg/Export
way:
#if defined(_MSC_VER) && defined(OSG_DISABLE_MSVC_WARNINGS).

Attachment contains all changed Export files in their original locations."

fa84f280f6 Renamed the osgVolume::Layer/ImageDetails parameters RescaleIntercept and RescaleSlope to more general TexelOffset and TexelScale, and changed type to Vec4.

a4dedc227b Refactored RayTracedTechnique to allow the position of the rendered part of the volume to be decoupled from the image data. 2009-07-02 18:49:59 +00:00
Robert Osfield
b7b065abe3 Refactored the Registry::ReadFileCallback, WriteFileCallback and ReaderWriter::Options to they are now defined in their own header and in the osgDB namespace.
Introduced a new FindFileCallback to Registry to compliement the existing ReadFileCallback and WriteFileCallback.

Added support for assign Find, Read and WriteFileCallbacks to osdDB::Options to enable plugins/applications to override the callbacks just for that
read/write call and any nested file operations
