GeometryHelper.IsInFront Method

GeometryHelperIsInFront Method

Determines whether the point is in front of the triangle.

Namespace: DigitalRune.Geometry
Assembly: DigitalRune.Geometry (in DigitalRune.Geometry.dll) Version: 1.18.0.0 (1.18.2.14427)

Syntax

C++

Copy

public static float IsInFront(
	Triangle triangle,
	Vector3F point
)

Public Shared Function IsInFront ( 
	triangle As Triangle,
	point As Vector3F
) As Single

public:
static float IsInFront(
	Triangle triangle, 
	Vector3F point
)

static member IsInFront : 
        triangle : Triangle * 
        point : Vector3F -> float32

Parameters

triangle: Type: DigitalRune.Geometry.ShapesTriangle
The triangle.
point: Type: DigitalRune.Mathematics.AlgebraVector3F
The point.

Return Value

Type: Single
A value greater than 0 if the point is in front. A value less than 0 if the point is on the back-side.

Remarks

A point is in front of the triangle if the vertex order of the triangle viewed from the point position is counter-clockwise (CCW). The absolute of the returned value is linearly proportional to the distance from the triangle plane.
