and TabPlaneDragger.cpp:
TabPlaneDragger(float handleScaleFactor=20.0f);
The reason for this is that the default OSG tab sizes are way bigger than
those we used in our application so far. And since handleScaleFactor_
is already a (constant) class member, I see no objection against making
it user defined."
indexed draws instead of plain array draws to save some amount of main memory.
Draw performance does not change with the nvidia binary blob as well as with
the open source drivers."
My previous patch for Atomic Counter Uniform provide new template implementation
of Matrix{2,3,4}x{2,3,4}{fd}. This new implementation use Column-Major Matrix.
Original code define matrix as Row-Major matrix like other Matrix in OSG, and
my matrix implementation break compatibility with previous code.
For example osg_normalMatrix define in osg::State report by Roland Hill.
Thanks to Paul Martz to spot me when the bug appear."
Not sure why my system seems to be so sensitive to these problems.
But attached is a fix which seems to stabilise the example.
Note: it only seems to crash intermittently when spinning the object with
your mouse.
So I assume this is a threading issue because of the data variance missing
in some of the text node setups in the example.
"
- add non square matrix
- add double
- add all uniform type available in OpenGL 4.2
- backward compatibility for Matrixd to set/get an float uniform matrix
- update of IVE / Wrapper ReadWriter
implementation of AtomicCounterBuffer based on BufferIndexBinding
add example that use AtomicCounterBuffer and show rendering order of fragments,
original idea from geeks3d.com."
1) they use direct link to texture
-> this is already handle by current plugin : OK
2) they defined colors with only 3 color components
-> it leads to a crash when trying to acces to the fourth component
I fixed that
3) they contain empty primitive lists
-> reading is ok, but osgviewer crashes when trying to display the geometries
The reason is that osg assume that DrawElementsare never empty (blunt acces to DrawElements.front() in PrimitiveSet.cpp)
I corrected this (on the plugin side), but I wonder :
Is it the responsability of plugins to create non empty DrawElements, or of osg core not to crash when they occur ?
If the responsability is on the osg core side, I can submit a patch to PrimitiveSet.cpp regarding that aspect.
4) they use a material binding scheme not supported by the plugin
->I've implemented a mechanism to handle this binding scheme
You will also find in the patch an example of these evil dae and comments on the offending elements.
They seems to be produced by ComputaMaps (www.computamaps.com)
They load well in Google Earth
