QRT ERROR CODES
Illegal Parameter
This error code no longer used. See Undefined Parameter.
Too Few Parameters
All the required parameters were not specified. See the QRT
Language Reference Guide for a list of required parameters to
this command. This error message also appears if a command
line option with no argument is passed to QRT.
Illegal Object Type
QRT does not understand this primitive type.
Malloc Failure
QRT was unable to allocate enough memory. Either reduce the
object tree size, or run QRT on a machine with more memory.
Syntax Error
Improper QRT syntax, such as a BEGIN_BBOX with no matching
END_BBOX.
Internal Error
(May be 'Programmer Confusion Error' on some versions). This
error should never occur. If it does, either there is some
illegal value not caught during input parsing, or there is a
programming error in the QRT system.
File Error
QRT couldn't open or close the output file. Check that the
file name adheres to the naming convention used for your
computer.

Pattern not found
A pattern was attached to a primitive, but this pattern was
never defined.
Pattern already defined
Two patterns were defined with the same name.
No observer defined
No observer was defined to QRT.
Undefined parameter
QRT does not recognize this parameter type. Either it is not
legal, or not legal in this context.
World contains non-homogeneous object
Error code not supported by this version of QRT.
An index of refraction is 0
An object that is transparent has an index of refraction equal
to zero.
Illegal color_info value
An object surface characteristic was defined improperly. Most
take values in the range 0.00 to 1.00.
Parameter should be >= 0
This parameter only takes values greater than zero, but it was
given a value less than zero.
Zero multiplier
A pattern size multiplier is zero. Use only positive values.
QRT Ray Tracer Page 2 Error Codes
Undefined name
An INSTANCE_OF primitive attempted to use a name that was not
defined in the instance definition tree.
Left paren expected
There should be a left parenthesis on this line.
Right paren expected
There should be a right parenthesis on this line.
Illegal vector structure
A position or direction vector of the form (x,y,z) was
specified improperly.
Illegal color triple
A color triple of the form (r,g,b) was specified improperly.
Illegal command line argument
An illegal command line option was specified. The legal
command line options are: -xres, -yres, -aspect, and -foclen.
The first two take integer arguments; the others take floating
point arguments.
