Hi, update: working! ... almost correctly
I have recently realized, that the problem may be caused by me not treating the fourth vector component (w) well - but if i use .project() method of either osg::Vec4d or osg::Vec4dH, it produces infinity for directional lights, which is expected, but how do i treat such values ? :? the light is finally positioned well :D if i alter the fourth component not to be zero, but some small value close to zero, just before using .project() method on the light's position. but i do not want to keep using this kind of hack. is there another way? i need to get the light's position to be able to compute precise vectors for lighting equations ... Thank you for suggestions!
