associated <stdlib.h> header. This breaks the build on my Solaris setup.
Rather than adding the missing <stdlib.h> include, I have changed the
atof() calls to osg::asciiToDouble(). This is the same as was done
throughout the other plugins recently, for locale independance.
I've attached updates to the svn trunk, the fix is also appropriate for
the 2.8.* branch."
dragger="box" or dragger="trackball"
and
technique="light" or technique="isosurface" or technique="iso" or technique="mip"
and
tf="transferfunctionfile.tf"
i.e.
<volume dragger="box">CardiacCT</volume>
<volume tf="colour.tf">CardiacCT</volume>
<volume technique="isosurface">CardiacCT</volume>
Note that this technique will require ARB_texture_env_crossbar (or NV_texture_env_combine4), as it mixes two textures in the first texture unit, and just does the lighting in the second. I doubt this will be a problem for any card that can already handle GLSL programs, though."
panning for left-right drags, but was zooming for up-down drags. I
changed it to pan both directions as I believe that is the correct
behaviour. If the original combination pan-zoom behaviour was
intentional, please let me know."
behind osgText::Text. I made it so the box would get drawn using
whichever BackdropImplementation was selected. However, I did not
implement STENCIL_BUFFER. In that case it defaults to drawing the
bounding box using POLYGON_OFFSET instead.
Also made it so the BOUNDINGBOX and FILLEDBOUNDINGBOX are drawn with a
settable color and margin size.
While I was at it I tightened up the values applied with DEPTH_RANGE
and POLYGON_OFFSET, not just for drawing the bounding box but also for
drawing backdrop text (these values must be coupled since the bounding
box has to be drawn deeper in Z than the backdrop text). The values
in use before seemed like overkill and I was seeing some z-clipping
with my background scenery in the case of DEPTH_RANGE. If there was a
good reason for the large values please let me know...."
even if they have had DataVariance DYNAMIC explicitly specified. Then
when an application attempts to dynamically update the geometry in the
frame loop the primitive sets and data arrays are no longer as
expected, leading to display and/or memory corruption.
Attached is a simple fix. "
Note from Robert Osfield, tweaked Colin's changes to that it use != DYNAMIC as the the test rather than == STATIC.
