Hi Martin,
For basic types like Vec3, BoundingBox you can simply create a table with
the named elements and the LuaScriptEngine will adapt these to the
appropriate osg::Vec3 i.e.
For a vec3 :
{x=10,y=2,z=20}
For a colour vec4:
{r=0.4,g=0.2,b=0.1,a=1.0}
For a bounding box:
{xMin=0, yMin=0, zMin=0, xMax=10, yMax=10, zMax=10}
For a Matrix it'll match against 16 numbers in a table. Which I can't
remember off the top of my head the most convenient form for.
Robert.
