Methods

ClosestPoint(float3)

Returns the closest point to p on this triangle

Declaration
public float3 ClosestPoint(float3 p)
Parameters
Type Name Description
float3 p

The point to get the closest point to
Returns
Type Description
float3

The closest point on this triangle

IsDegenerate()

Declaration
public bool IsDegenerate()
Returns
Type Description
bool

ProjectPointOntoPlane(float3)

Projects a point in 3D space onto the plane this triangle lies in

Declaration
public float3 ProjectPointOntoPlane(float3 point)
Parameters
Type Name Description
float3 point

The point to project
Returns
Type Description
float3

The closest point on the plane of this triangle, it's possible for the returned point to be outside of the triangle itself.

Raycast(Ray, out float)

Checks if the specified ray hits the triangle. Möller–Trumbore ray-triangle intersection algorithm implementation.

Declaration
public bool Raycast(Ray ray, out float hitT)
Parameters
Type Name Description
Ray ray

The ray to test hit for.
float hitT

how far along the ray was the triangle hit
Returns
Type Description
bool

true when the ray hits the triangle, otherwise false

Raycast(Ray, out float3)

Checks if the specified ray hits the triangle. Möller–Trumbore ray-triangle intersection algorithm implementation.

Declaration
public bool Raycast(Ray ray, out float3 point)
Parameters
Type Name Description
Ray ray

The ray to test hit for.
float3 point

The point where the triangle was hit.
Returns
Type Description
bool

true when the ray hits the triangle, otherwise false
