[osg-submissions] VPB float/double bounding box

[christophe loustaunau]

Hi,

I have compile OSG with OSG_USE_FLOAT_BOUNDINGBOX and
OSG_USE_FLOAT_BOUNDINGSPHERE to OFF. Then, when I try to
compile VPB, it hangs on :

So, I have added the same two options as OSG in Cmake for VPB  :

OPTION(OSG_USE_FLOAT_BOUNDINGSPHERE "Set to ON to build VirtualPlanetBuilder
with float BoundingSphere instead of double." ON)
MARK_AS_ADVANCED(OSG_USE_FLOAT_BOUNDINGSPHERE)
IF(NOT OSG_USE_FLOAT_BOUNDINGSPHERE)
    ADD_DEFINITIONS(-DOSG_USE_DOUBLE_BOUNDINGSPHERE)
ENDIF(NOT OSG_USE_FLOAT_BOUNDINGSPHERE)

OPTION(OSG_USE_FLOAT_BOUNDINGBOX "Set to ON to build VirtualPlanetBuilder
with float BoundingBox instead of double." ON)
MARK_AS_ADVANCED(OSG_USE_FLOAT_BOUNDINGBOX)
IF(NOT OSG_USE_FLOAT_BOUNDINGBOX)
    ADD_DEFINITIONS(-DOSG_USE_DOUBLE_BOUNDINGBOX)
ENDIF(NOT OSG_USE_FLOAT_BOUNDINGBOX)

With these two options, It build fine. Maybe we could do a better thing,
like checking if OSG was build with OSG_USE_FLOAT_BOUNDINGBOX or not, and
set the same thing for VPB. But I don't know enough CMake to do that !


Here is the modify CMakeLists.txt for VPB.
