Quat::SetFromAxisAngle

Syntax

void Quat::SetFromAxisAngle(const float3 &rotationAxis, float rotationAngleRadians); [11 lines of code]

Sets this quaternion by specifying the axis about which the rotation is performed, and the angle of rotation.

Parameters

const float3 &rotationAxisThe axis of rotation. This vector must be normalized to call this function.

Performance

45.158nsecs/call ≈ 22.14M calls/second ≈ 369.08k calls/frame (@ 60fps).
This function does not perform dynamic memory allocation.
