VECReflect

C Specification

#include <revolution/mtx.h>

void VECReflect ( const Vec* src, const Vec* normal, Vec* dst );

Arguments

`src`	Pointer to incident `Vec`. `src` must point toward the surface.
`normal`	Pointer to `Vec` that is normal to the surface. `normal` must point away from the surface.
`dst`	Pointer to the unit vector `Vec` that is reflected. Acceptable if `dst = src` or `dst = normal`.

Return Values

None.

Description

Reflects an incident vector across the normal vector such that the angle of incidence equals the angle of reflection. This function is intended for use in calculating surface reflections.

Note: Although the incident vector does not need to be a unit matrix, the resultant vector is normalized.
