c43607c14d Added support for specificing the eye mapping and seperation between the
horizontal and veritical split stereo modes.

Renamed osg::Image::ensureDimensionArePowerOfTwo() to osg::Image::ensureValidSizeForTexturing().

341ffb2361 Further work on cleaning up SceneView and Camera, in particular moving strereo
support out of Camera and into SceneView. Also enabled the option to set the
projection and modelview matrices directly on SceneView thereby removing the
dependance on osg::Camrea to control the view of the scene.

14b4b7f98c Solaris PKG distribution now makes a shar (self-extracting shell archived)
changed makepgk to do this.

Changed another one of those pesky cout = std::cout in CullVisitor.cpp

6ed233d0d2 Added DataVariance enum and set/get fields to osg::Object to help identify
which objects have values that vary over the lifetime of the object (DYNAMIC)
and ones that do not vary (STATIC).  Removed the equivalent code in
osg::Transform, StateSet and StateAttribute, as these are now encompassed
by the new DataVariance field.

Removed MatrixMode enum from Matrix, and associated fields/parameters from
osg::Transfrom and osg::NodeVisitor, since MatrixMode was not providing
any useful functionality, but made the interface more complex (MatrixMode
was an experimental API)

Added ReferenceFrame field to osg::Transform which allows users to specify
transforms that are relative to their parents (the default, and previous behavior)
or absolute reference frame, which can be used for HUD's, camera relative
light sources etc etc.  Note, the view frustum culling for absolute Transform
are disabled, and all their parents up to the root are also automatically
have view frustum culling disabled.  However, once passed an absolute Transform
node culling will return to its default state of on, so you can still cull
underneath an absolute transform, its only the culling above which is disabled.

360247225e Added new osg::DrawPixels class with encapsulates glDrawPixels as and
osg::Drawable.  Added osg::Image::readPixels to osg::Image.

Made osg::LightSource to default to cullActive set to false to that LightSource
nodes don't get culled by default.

6f65e86057 Further work on removing Camera references from NewCullVisitor and releted
classes, this work paves the way for making osg::Camera an optional
extra rather than a requirement for rendering.

e0adca775b Reinstated Norman Vine's TARGET_BASENAME variable in the makefiles and
added prefixes and suffixes to libs and plugins.  ALl this to accomodate
cygwin...

Also added INST_SYS_PREFIX and INST_SHARE_PREFIX for installation, as well
as "standardizing" the install locations for the various platforms.

3e6638320a The new order for building OSG. All Makefiles are replaced and
the Make directory is left with four files only :
    makedefs
    makerules
    makedirrules
    instrules

These work for all platforms supported so far, which include :
    Linux
    Irix
    Solaris
    MacOSX
    Cygwin
    FreeBSD

3351306d80 Added new osg::Projection node, and osgUtil::NewCullVisitor which are work
in progress for the new support for controlling the projection matrix from
within the scene graph.

Also Added osg::State::getClippingVolume(), getProjectionMatrix() and
getModelViewMatrix() with allows drawables to access the current projection,
and model view matrices and the view frustum in local coords to the drawable.

56cee8c711 Move the applying of Projection and ModelView matrices into osg::State so that
it now maintains references to the last applied matrices, automatically doing
lazy state updating.  This simplifies the various places in the OSG which
were previously doing the applying, add paves the way for managing the
projection matrix within the scene graph.

Remove MemoryAdapter and mem_ptr as they arn't being used, and can potentially
confuse users by their existance.

7927335edf Added support for VERTICAL_SPILT and HORIZONTAL_SPLIT stereo modes. 2002-03-27 10:52:40 +00:00
Robert Osfield
84d2d01163 Added support for osg::MemoryManager which is based upon Paul Nettle's
memory manager published at flipcode.com.  This can be turned on
with the OSG_USE_MEMORY_MANGER option which then uses custom global
new and delete operators as well as provide osgNew and osgDelete macro's
which add ability to log line and file from which calls are made.

Updated osg,osgUtil,osgDB,osgText and osgPlugins/osg to use osgNew/osgDelete,
and fixed memory leaks highlighted by the new memory manager.

b53b3038eb _cullMaskRight was not being initialized in the constructor which was
resulting in some sporadic problems when running stereo - occoasionally the
right eye view wouldn't appear!

8c9609b331 Added the fallback of intersecting with the a drawables bounding box, if the drawable
isn't a GeoSet and hence supported by the IntersectVisitor's GeoSet primitive
intersections code.

c49c62ee15 Integrated various changes worked on at the Glasgow Science Center. Changes
include change the CameraManipulators so they work with double for time
instead of float.  Also added support for DataType to osg::StateAttribute
and StateSet so that they can be set to either STATIC or DYNAMIC, this
allows the optimizer to know whether that an attribute can be optimized
or not.

e80496d5db Changed Texture so that is use lazy updating on texture paramters (Filter/Wrap)
mode by using a _texParamtersDirty flag in combination with an
applyTexParamters(State&) method which does the paramters setting in one
tidy bundle.  This new implementations replaces the CompileFlags submitted
yesterday.

Simplified NodeCallback by remove osg::NodeCallback::Requirements as they
are no longer needed.

Fixed comments in Drawable.

Put guards around cosf definations so that they are only used under Win32/Mac.

Fixed warning in CullVisitor.

d0ee300405 Fixed DrawCallback in Drawable and added CullCallback to Drawable
Cull Visitor now checks for a Drawable's CullCallback and calls it
if it exists.  It then prunes based on the return value (bool) of the
cull callback.

a6aa57a255 Added support for seperate traversal masks for standard, left and right
cull traversals.  This allows one to create seperate rendering for left
and right eyes when doing stereo.

386b87d4a0 Cleand up the root Makefile.
Moved CullVisitor/RenderStage/RenderStageLighting across to managing lights
entirely within RenderStageLighting, and changed the management of modelview
matrices so that RenderLeaf now stores the absolute modelview matrix, rather
than a model matrix as done previously. The later allows RenderLeaf's to do
a glLoadMatrix rather than a glPushMatrix/glMultMatrix/glPopMatrix.

d9398af300 Fixed a bug in the drive manipulator which was due to it using the local
coords of the intersection point with the scene rather than the world
coord value for that point.  The code now uses
osgUtil::Hit::getWorldIntersectionPoint() method for getting the world coords.

Added support for getWorldIntersectionPoint to Viewer.cpp.

Put and #ifdef around the setting of the default display list visitor so
it nolonger sets in under IRIX. This is a world around to the IR graphics
imbending lighting info into display lists, if the display lists are
created before state is set up it produces lighting artifacts such as
flickering.  Remove the the default display list init visitor removes
these problems, display lists are then built on the fly and drawables
a drawn for the first time.

634ef7e3a6 Fixed the osgUtil::Optimizer::FlattenStaticTransformVisitor so that it
does not flatten drawables which have double references to them, but only
one reference with a static transform on it.  This case can't be flattened
but this wasn't picked up.  The code now detects the case correctly.

d12a726d5b Various investigations into culling errors w.r.t matrix inversion resulted in
the conclusion that the osg::Matrix::inverse was broken, have lifted a new
implementation from sgl and it seems to work fine.  Will need further testing
but looks good.

a703130aa0 Have taken a few more steps towards support for view dependant transformations
by adding a ComputeTransformCallback to osg::Transform, and have now removed
the recently added AutoTransform since it is nolonger required.  Have also
updated CullVisitor to account for the new ways for tracking transformation
matrices in the scene.

7b370fcb57 Made the LineSegment destructor protected to force users to create segments
on the stack thus ensure that they arn't created locally and have their
memory deleted incorrectly.

Also updated the IntersectVisitor so that it no used osg::ref_ptr<> internally
for storing all data. Have also move the IntersectState helper class to inside the
IntersectVisitor which simplifies the external interface to the class.
