408c2a2267 From Paul Martz, "Here's my proposed change regarding the osg-users post "small feature culling threshold". I've updated the comments and brought the default values into agreement, but didn't bother to add the environment variable support." 2011-09-13 09:59:21 +00:00
Robert Osfield
698a284da8 From Sukender, "I added a tiny check to avoid an integer divide-by-zero, when image is invalid (ie. all values are 0)." 2011-09-13 09:46:22 +00:00

abb7228d56 From Sukender, "I added a crash-guard against corrupted 3DS files, having faces indexes out of the range of existing vertices." 2011-09-13 09:43:45 +00:00

6d1ba5b06d From Farshild Lashkari, "Attached is a simple patch that avoids the depth write pass in Text::renderWithDelayedDepthWrites if the current osg::State object has GL_DEPTH_TEST disabled." 2011-09-13 09:21:07 +00:00

6e6dafcd3e From Luc Frauciel, "When osgUtil::DelaunayTriangulator triangulate() function ends with no triangle generated, it crashes. 
This patch fixes that"

796ccd14c8 From Cedric Pinson, from three submissions: 
"Here a patch that correct like the previous assign collada material name
to stateset."

and

"I changed how the collada reader set object name in osg. Current
implementation use collada ID to setup name. with this patch I use
collada name to setup name in osg object and if collada provide no name
I use as fallback ID. I am not sure we want this fallback.

The motivation of this change is that when an artist set names to its
objects and export to collada, I am not able to use those names in osg
to retrieve the node."

and

"Here the update of the file that fix the light id stuff"

1fd3c84287 Added fine grained computation of the far plane when using the COMPUTE_NEAR_FAR_USING_PRIMITIVES ComputeNearFarMode. 
Added COMPUTE_NEAR_FAR_USING_PRIMITIVES option that provides the original functionality where only the near plane
is computed in a fine grained way, with the far plane being computed simply from bound volumes.
