QUATSquad

C Specification

#include <revolution/mtx.h>
void C_QUATSquad (
    const Quaternion* p,
    const Quaternion* a,
    const Quaternion* b,
    const Quaternion* q,
          Quaternion* r,
          f32         t );

#define QUATSquad  C_QUATSquad

Arguments

p Pointer to the first Quaternion.
a Pointer to the first extra inner-quadrangle Quaternion.
b   Pointer to the second extra inner-quadrangle Quaternion.
q Pointer to the second Quaternion.
r Pointer to resultant Quaternion. Contains the result of interpolation between p and q. Acceptable if r = either of p,a,b,q.
t Interpolation parameter. If t =0.0, the result becomes equal to p. If t =1.0, the result becomes equal to q.

Return Values

None.

Description

Performs spherical 3D (Squad) interpolation on two quaternions. Two quaternions for special control (inner-quadrangles) are required to carry out this calculation.
