C++ (Cpp) kmVec4Assign Examples

Example #1

File: vec4.c Project: Kazade/kazmath

kmVec4* kmVec4Normalize(kmVec4* pOut, const kmVec4* pIn) {
	kmScalar l;
    if (!pIn->x && !pIn->y && !pIn->z && !pIn->w){
        return kmVec4Assign(pOut, pIn);
    }

	l = 1.0f / kmVec4Length(pIn);
    pOut->x = pIn->x * l;
	pOut->y = pIn->y * l;
	pOut->z = pIn->z * l;
	pOut->w = pIn->w * l;

	return pOut;
}

Example #2

File: vec4.c Project: bernardinus/kazmath

/// Normalizes a 4D vector. The result is stored in pOut. pOut is returned
kmVec4* kmVec4Normalize(kmVec4* pOut, const kmVec4* pIn) {
    if (!pIn->x && !pIn->y && !pIn->z && !pIn->w)
        return kmVec4Assign(pOut, pIn);

	kmScalar l = 1.0f / kmVec4Length(pIn);

	kmVec4 v;
	v.x = pIn->x * l;
	v.y = pIn->y * l;
	v.z = pIn->z * l;
	v.w = pIn->w * l;

	pOut->x = v.x;
	pOut->y = v.y;
	pOut->z = v.z;
	pOut->w = v.w;

	return pOut;
}
