Camera identifiers may be declared to make scene files more readable and to parameterize scenes so that changing a single declaration changes many values. You may declare several camera identifiers if you wish. This makes it easy to quickly change cameras. An identifier is declared as follows.
- #declare
IDENTIFIER =
CAMERA
|
- #local
IDENTIFIER =
CAMERA
Where IDENTIFIER is the name of the identifier up to 40 characters long and CAMERA is any valid camera statement. See "#declare vs. #local" for information on identifier scope. Here is an example...
#declare Long_Lens = camera { location -z*100 angle 3 } #declare Short_Lens = camera { location -z*50 angle 15 } camera { Long_Lens // edit this line to change lenses look_at Here }
