facilitate the subclassing of Image providing interactive behaviours so as
used in the vnc interactive VncImage class.
osgViewer::InteractiveImageHandler provides an event handler that convertes osgGA
mouse and keyboard events into the coordinate frame of an image based on ray intersection with geometry in
the associated subgraph.
Changed the ordering of events processing in Viewer and CompositeViewer to allow
scene graph event handlers to take precidence over viewer event handlers and camera manipulators
they are written to disk, either inline or as an external file. Added support for
this in the .ive plugin. Default of WriteHint is NO_PREFERNCE, in which case it's
up to the reader/writer to decide.
is not the usual OpenGL BOTTOM_LEFT orientation, but with the origin TOP_LEFT. This
allows geometry setup code to flip the t tex coord to render the movie the correct way up.
"Attached is some fixes for Image::readImageFromCurrentTexture. It was
failing when used with a new Image object (some of the fields were
not set before they were used, and some were set to the wrong values).
A new optional parameter was added to give the desired data type, which
defaults to GL_UNSIGNED_BYTE, so programs should only need a recompile
to work properly."
Removed the rescalling of images in osg::Image during texture apply, moving
the rescale so it is locally calculated. This solves an outstanding threading
problem which occured by multiple draw threads all tried to rescale the same
image at one time.
Made osg::Image ptr in osg::Texture2D non mutable as it is no longer modified
during apply.
osg::Image::setImage has also been modified to require the AllocationMode
mode to be passed to it so that it knows how to delete the data once the
image goes out of scope.
Port the image plugins across to specify the new AllocationMode, and converted
them across to using new/delete in place of malloc/free.
added osgtexture1D demo which currently is simply copy of osgtexture2D. I
will be modifying it to do 1D texturing next.
Fixed a bug in osg::Texture3D relating to checking of existance of
texturing.
Merged some fixes to the pfb loader from Ulrich Hertlein.
Supported added for precompiled mip maps stored in osg::Image, and read
by osg::Texture.
Updates to TerraPage loader for support of compressed texture images and
precompiled mip maps.
renamed osg::Image::pixelFormat(), internalTextureFormat(),dataType() to
osg::Image::getPixelFormat() etc. These changes are to bring it more
into line with the style of the rest of the OSG.
Updated the rest of the distribution to take account for these names changes.
