e1a6a18036 Added missing _nodePath.clear() and _segHitList.clear() to InteresectVisitor::reset(). 2002-08-02 15:14:59 +00:00

067dc6cddf Fixes to the new texture subloading methods. 2002-07-29 00:04:07 +00:00
Robert Osfield
6b59f66d80 Checked in new methods for setting up texture subloading, these allow the 
user to control which parts on an image are subloaded from, and how big
the initial texture is.

02bb66a572 Checked in Pavel's updates for non texured surfaces. 2002-07-28 23:27:21 +00:00
Robert Osfield
05472135b0 Added set/getUnrefImageOnApply() methods and associated flag and 
code in Texture::apply() to set the _image to 0 on apply.  Note,
this will only work when you have a single graphics context, as
with multiple graphics contexts one can't delete the image after
the first apply, as there will be more than one texture object to
update.

63e3364cc3 Checked in Marco's commented out #defines/rejigged struct names to get things 
compiling under Windows, will need to check this in future as it may change with regeneration of parser files
with lex/yacc.

3cba9a52ef Updates NEWS file for 0.9.0 release. 
Added default computeBound() implementation to osg::Drawable which uses
a PrimtiveFunctor to compute the bounding box in a generic way, that
will work for all Drawable subclasses that implement the accept(PrimitiveFunctor&).
 2002-07-18 22:35:54 +00:00

325b119218 Moved the 't' operation on texture modes across to use the new

ff8b4c001d Rewrote the osg::Drawable::AttributeFunctor and PrimtiveFunctor to make

b513517502 From Brede Johansen 
"I have found one bug in the ConvertFromFLT::visitFace() function.  In the
early days of the Flight format, before the LightPoint record existed
they used face records with a light (-point) attribute."
 2002-07-18 14:29:32 +00:00
Robert Osfield
8036901ea1 Rewrote osg:Statistics so that it is PrimitiveFunctor as is now completely 
decoupled from osg::Drawable.  The Drawable::getStats() virtual method
no longer exists.

Updated the Viewer to use the osg::Statistics incarnation and reformated stats
to clean it up.
 2002-07-18 14:20:01 +00:00
Robert Osfield
f2b6f8c873 Added code into osg::LightSource so it correctly computes its bounding 
sphere, taking into account any subgraph below, and the light itself
if it is not a infinite light.

Robert Osfield
7a8eeb3c92 Converted the osg::Material::set/getShininess option to use the standard 
OpenGL range of 0.0 to 128.0 instead of the previous normalised shiniess
range. This brings it inline with the way the rest of the OSG uses a
1 to 1 mapping to OpenGL.

Converted the various loaders to use the new range, which is almost all
cases was simply removing the /128.0f which was required before!

6524548eb2 Fix for Win32 build. 2002-07-17 12:21:53 +00:00
Robert Osfield
8c0d510571 Several items of work related to adding a manual creation of occluders 
option to the osgoccluder demo.

First the osgGA classes have been generalised a little to better support
new GUIEventHandler subclasses.

Second osgGLUT has a new option for registering a user defined event handler,
the allows the application to add externally extra options to the osgGLUT viewer.

Third, the osgoccluder demo now works in two modes. The original create
four occluder sides to wrap an loaded model, the second an interactive
mode which allows the users to add occluders to the model by pointing
to points and pressing 'a' to add a point, the 'e' to end the occluder
polygon, polygons must be convex, planer and be defined in an anitclockwise
order.  To start the osgoccluder in this mode one simple runs it with the
'-c' option.  Run osgoccluder with no parameter to get a list of options.

9c56a57de3 Fixed the orientation of the osgreflect demo so that the reflection plane 
is orientated towards the viewer.

Changed the lightmodel ambient level to 0.1,0.1,0.1 instead of 0.0, so that
a small amount of ambient lighting is available to render back surfaces.
The osgreflect and osgprerender suffered unexpected behaviors because of
no lighting on the backfaces.
 2002-07-15 13:20:41 +00:00
Robert Osfield

Robert Osfield
db892e6bfe Added State::disableTexCoordPointersAboveAndIncluding( unit ) method so that 
all unsed texture units can be turned off simply within Drawables such
as Geometry and GeoSet. This can be used to prevent bleed of arrays from
one object to the next - which can cause crashes.

6f392cdbfa Ported distribution across to use the new osg::MatrixTransform and osg::BlendFunc 
class instead of osg::Transform and osg::Transparancy respectively.
 2002-07-12 18:12:01 +00:00
Robert Osfield
8128265e09 Have added a #define USE_DEPRECATED_API to include/osg/Export, and 
various
osg header and source files to optional compile in deprecated parts of
the
OSG API.

Have renamed osg::Transparency osg::BlendFunc to bring it in line with
the
rest of the OSG's StateAttribute classes which are named after their
OpenGL counterparts.  include/osg/Transparency still exists and is
simply
a typedef to BlendFunc and is enclosed in a #ifdef USE_DEPRECTATED_API
block.

The matrix methods in the osg::Transform class have been
moved/replicated in
a osg::MatrixTransform sublcass from osg::Transform.  The old matrix
functionality is still present in the osg::Transform class but is guard
by #ifdef USG_DEPRECATED_API blocks.  One should now think of
osg::Transform
as being a Transform Node base class.  MatrixTransform has all the
functionality of the original Transform class, so should be used
instead.

c4c97a0f64 Moved the code referencing osg::BoundingBox::isValid() and 
osg::BoundingSphere::isValid() across to use the valid() methods, the later
being more consitent with other classes such as osg::ref_ptr<>.

d763a47d2e Mods to MemoryManager to make the optimized build produce dummy 
implementations for all the public functions found in the header,
this should prevent problems when not compiling in the MemoryManager
under IRIX 64 build.
 2002-06-20 18:17:36 +00:00
Robert Osfield
4f4f68e961 Added support for reading the new OSG_MAX_TEXTURE_SIZE environmental variable 
inside the osg::Image::ensureValidSizeForTexturing() method. The
smallest of GL_MAX_TEXTURE_SIZE and OSG_MAX_TEXTURE_SIZE is used for the
final max texture size.

This new env. var. allows users to deliberate cap the size of their textures
so they can test whether their models are limited by texture memory.  If
reducing the max texture size increases performance then you are limited
by texture memory!

Added support for osg::BoundingSphere::expandBy*(osg::BoundingBox) and have
added osg::BoundingSphere/Box::valid() which deprecates isValid(), this
is to be more consistent with other classes in the OSG.

other than the standard osg::Light.
 2002-06-19 08:34:19 +00:00
Robert Osfield
5e85cd59ab Added support for occluders occluding other occluders, which helps reduce 
the number of occluder that will be used in cull traversal to only the
ones that will be effective. Note. Holes in occluders arn't handled in
this occluder occlusion test, will implement this later.

structor from a char* to a std::deque.  Changed a names of couple of the
convinience functions in osgDB/FileUtils to better reflect the two
public FilePathList's - DataFilePathList and the LibraryFilePathList.

Added support into the osgDB::Registry::readNode/Image/Object methods
for pushing and popping the path of the current file being loaded.

7adb75c572 Added occluder hole test code into the osgoccluder demo. The code works, 
but I've commented it out right now as the Geode physically representing
the occluder doesn't yet have a hole in it - just a cosmetic thing.

a fully functioning NodeKit.

Also reimplement notify() to try an prevent a crash which has been caused by
to objects in notify.cpp being initiliazed twice, the second time the auto_ptr
holding the dev/null ofstream was being initilized to 0.

d91b848a63 Checked in migration from osgUtil based GUIAdapter code to Neil Salter's 
osgGA (Gui Abstraction).  This may break users code, but all it should
require to fix the builds should be a change from
osgUtil::CameraManipulator (etc) to osgGA::CameraManipulator and
include <osgUtil/CameraManipulator (etc) to osgGA/CameraManipulator and
the extra dependency of the link line.
