C++ (Cpp) float3::ProjectToNorm Examples

Example #1

File: float3.cpp Project: chengzg/MathGeoLib

void float3::Orthonormalize(float3 &a, float3 &b, float3 &c)
{
	assume(!a.IsZero());
	a.Normalize();
	b -= b.ProjectToNorm(a);
	assume(!b.IsZero());
	b.Normalize();
	c -= c.ProjectToNorm(a);
	c -= c.ProjectToNorm(b);
	assume(!c.IsZero());
	c.Normalize();
}

Example #2

File: Circle.cpp Project: 360degrees-fi/tundra

float3 Circle::ExtremePoint(const float3 &direction) const
{
	float3 d = direction - direction.ProjectToNorm(normal);
	if (d.IsZero())
		return pos;
	else
		return pos + d.ScaledToLength(r);
}

Example #3

File: Plane.cpp Project: Ilikia/naali

Plane::Plane(const Line &line, const float3 &normal)
{
	float3 perpNormal = normal - normal.ProjectToNorm(line.dir);
	Set(line.pos, perpNormal.Normalized());
}

Example #4

File: Plane.cpp Project: Ilikia/naali

Plane::Plane(const Ray &ray, const float3 &normal)
{
	float3 perpNormal = normal - normal.ProjectToNorm(ray.dir);
	Set(ray.pos, perpNormal.Normalized());
}
