-Without the above options the immovable camera sits at the origin $(0,0,0)$ of the World, looking in the positive $Y$ direction, i. e. default settings of \verb+3Droo=0+, \verb+3Dcoo=0 0 0+ and  \verb+3Dc2c=0 -1 0+ are assumed. (Note that $\overrightarrow{C2C}$ is the opposite of the view vector!)

 Thus, in order to get a `front view' of the 3D object it is sufficient to gradually increase the radius $ROO$ from \LaTeX{} run to \LaTeX{} run until the object or group of objects can be fully seen in the viewport. Since the object size in terms of world coordinate units may differ in orders of magnitude between U3D files, the optimal `\verb+3Droo+' setting might be found by experimenting with a series of geometrically increasing numbers, such as 1, 10, 100, 1000, 10000 etc. to get a rough approximation and by subsequent fine tuning using smaller changes.
