What is the difference between #define NAME VALUE and const int NAME = VALUE in GLSL 410 core?
As far as I can see, they both create a constant integer.

If the question is on-topic, it does not matter it has already an answer on a different SE site; just self-answer this question with what you have learned. \$\endgroup\$Sumurai8– Sumurai82015-09-09 15:14:52 +00:00Commented Sep 9, 2015 at 15:14

#define NAME VALUE is a macro, where all instances of NAME are replaced with VALUE by the pre-processor.
The compiler handles constants. This ensures type safety.
