C++ (Cpp) float2::IsNormalized Examples

Example #1

File: float2.cpp Project: Garfield-Chen/tng

void float2::Decompose(const float2 &direction, float2 &outParallel, float2 &outPerpendicular) const
{
	assume(direction.IsNormalized());
	outParallel = this->Dot(direction) * direction;
	outPerpendicular = *this - outParallel;
}

Example #2

File: float2.cpp Project: Garfield-Chen/tng

float float2::AngleBetweenNorm(const float2 &other) const
{
	assume(this->IsNormalized());
	assume(other.IsNormalized());
	return acos(Dot(other));
}

Example #3

File: float2.cpp Project: Garfield-Chen/tng

float2 float2::Reflect(const float2 &normal) const
{
	assume2(normal.IsNormalized(), normal.SerializeToCodeString(), normal.Length());
	return 2.f * this->ProjectToNorm(normal) - *this;
}

Example #4

File: float2.cpp Project: Garfield-Chen/tng

float2 float2::ProjectToNorm(const float2 &direction) const
{
	assume(direction.IsNormalized());
	return direction * this->Dot(direction);
}

Example #5

File: float2.cpp Project: Ilikia/naali

float2 float2::Reflect(const float2 &normal) const
{
    assume(normal.IsNormalized());
    return 2.f * this->ProjectToNorm(normal) - *this;
}
