Quat::SlerpVectorAbs

Syntax

MUST_USE_RESULT float3 Quat::SlerpVectorAbs(const float3 &from, const float3 &to, float angleRadians); [12 lines of code]

Returns the 'from' vector rotated towards the 'to' vector by the given absolute angle, in radians.

This function slerps the given 'from' vector towards the 'to' vector.

Parameters

const float3 &fromA normalized direction vector specifying the direction of rotation at angleRadians=0. const float3 &toA normalized direction vector specifying the target direction to rotate towards. floatangleRadiansThe maximum angle to rotate the 'from' vector by, in the range [0, pi]. If the angle between 'from' and 'to' is smaller than this angle, then the vector 'to' is returned. Input values outside this range are silently clamped to the [0, pi] interval.

Return Value

A spherical linear interpolation of the vector 'from' towards the vector 'to'.
