vector4c

vector4c is structure used to describe a 4-dimensional vector in signed 8-bit integer ('char') precision. This data type is less precise than vector4f but more compact.

Each vector component has the range -128…127, and vectors may or may not be normalised.

In Zeolite_defines.h:

typedef struct {
  signed char a;
  signed char b;
  signed char c;
  signed char d;
} vector4c;
