Line 883 in 00d0ab0

virtual vec3 value(double u, double v, const vec3& p) const = O;

here const = O should be const = 0 ，but not capitalized letter o.

Since i am not a native speaker, how do we discrible this case in English?

Thanks! “Spelling mistake” is fine. This would also commonly be referred to as a “typo”, slang for a typographical error. In this particular case, it was possibly due to OCR, so ... ocro? Ocrerr?
