you mean, if it would something like the following, it wouldn't be OO ?

----- Example, how _I_ would wish the SDL to be
... ----------------------------

#declare MySphere=sphere{<0,0,0>,5}
#declare MyMaterial=material{texture{pigment{color rgb 1}}}

MySphere.setCenter(<5,2,5>)
MySphere.setMaterial(MyMaterial)

MyMaterial.getTexture.setFinish(finish{ambient 0})

#declare MyBox=box{}
MyBox.setCorners(<-1,-2,-3>,<1,2,3>)
MyBox.setMaterial(MyMaterial.clone())
MyBox.getMaterial.getTexture.setFinish(finish{reflection 0.7 ambient 0.0
diffuse 0.2})
MyBox.translate(<-5,0,8>)

Scene.add(MyBox)
Scene.add(MySphere)
Scene.add(camera{lookAt 0, location y*5+z*-10})
Scene.add(lightSource{y*20, color rgb 1})

Scene.render()

Maybe I've done too much Java ...

this would IMHO provide a certain degree of compatibility, and allow a
perfect
manipulation of objects, after they've been declared ...

The mainThing I prefer in this solution, is:
- you can declare Objs (maybe even only the frame of the obj)
- specify afterwards, how to manipulate it
- add it to the Scene-Object if it should be taken into account while
rendering
- you can specify the moment, when the scene should be rendered ...
- do some cleanup, or prepair the next frame to be rendered ...
