b38f491c12 From Volker Walkiewicz (with tweaks from Robert Osfield): 
Fix to the update of the error metrics on the edges in the simplification mesh that are affected by an edge collapse.

Addition of 'n' and 'p' keyboard control in osgsimplifier example to allow users to control the sample ratio manually.

52dea86a3e From A. Botorabi, "slightly modified osgUtil's TangentSpaceGenerator class to allow the 
option for using or not using geom's indices for tangent space vectors
generation. now, Ruben's code is also used (it was disabled before). in
order to keep backward compatibility, the compute method behaves as before
in default case."

b5c4605d1c From Joran Jessurun, added font search fallbck that strips the leading path from the font file and then looks again. 2005-09-28 13:39:26 +00:00

05528abf25 From Chris Hanson: 
Spelling fixes in include/osg/LOD

   Negated priority in PagedLOD when using _rangeMode==PIXEL_SIZE_ON_SCREEN

   Added clampedPixelSize() methods to CullStack and CullingSet to return fabs()ed values.

   Changed LOD and PagedLOD ::traverse to use clampedPixelSize() methods.

e17ac7a8d9 Brede's changes for limited morphed vertex support. These changes allow 
a model with morphed vertecies to load correctly with LOD switches, but
does not implement the vertex morphing.

745834c329 Added triangle index functor to src/osgUtil/SphereSegment.cpp for computing 
the intersection between an indivual geometry and the sphere segment.

Converted the terrain in osgspheresegment to be an osg::Geometry based
drawable rather than a osg::ShapeDrawable/osg::HeightField one to make it
more practicle to use as a test for the new SphereSegment intersection code.

Robert Osfield
67e8e0b287 Added PolytopeVisitor to SphereSegment.cpp to help cull down to only drawables 
that intersect with the frustum of the SphereSegment. PolytopeVisitor may
eventually be pulled out to be more generally used along the lines of osgUtil::IntersectVisitor.
