vec3_t

All throughout the source code of every ID software game, I see large amounts of references to a data type called vec3_t. I have searched through every single source file and cannot find the definition of this data type ANYWHERE. Does ANYONE know what this is?

In quake if I remember correctly it's to do with camera angles.

Code:

---

typedef float vec_t;

typedef vec_t[3] vec3_t;

---

vec_3t: "3 angles that describe the camera viewing direction in Quake and other games."

A block structure from the code of Quake...

Code:

---

typedef struct {
                long            blocksize;
                vec3_t          angles;
                char[blocksize] messages;
              } block_t;

---

I'm not sure if this is of any use?
