Member Function Documentation

ClampListIndex()

static int AsImpL.MathUtil.MathUtility.ClampListIndex ( int  index, int  listSize  )

static

Clamp list indices.

Parameters

index	Index to be clamped.
listSize	Size of the list.

Returns

Will even work if index is larger/smaller than listSize, so can loop multiple times From https://www.habrador.com/tutorials/math/9-useful-algorithms/

ComputeNormal()

static Vector3 AsImpL.MathUtil.MathUtility.ComputeNormal ( Vector3  vert, Vector3  vNext, Vector3  vPrev  )

static

Compute the normal of a vertex of a triangle defined by its 3 vertices.

Parameters

vert	Vertex of the triangle where the normal is coputed.
vNext	Next vertex (counter-clockwise)
vPrev	Previous vertex (counter-clockwise)

Returns

The computed normal.

IsPointInTriangle()

static bool AsImpL.MathUtil.MathUtility.IsPointInTriangle ( Vector2  p1, Vector2  p2, Vector2  p3, Vector2  p  )

static

Check if a point is inside a triangle.

Parameters

p1	First corner in the triangle.
p2	Second corner in the triangle.
p3	Third corner in the triangle.
p	Test point

Returns

The result is true if the test point is inside the triangle.

IsTriangleOrientedClockwise()

static bool AsImpL.MathUtil.MathUtility.IsTriangleOrientedClockwise ( Vector2  v1, Vector2  v2, Vector2  v3  )

static

Check if a triangle oriented clockwise or counter-clockwise.

Parameters

v1	First vectex in 2D
v2	Second vectex in 2D
v3	Third vectex in 2D

Returns

True if the triangle is oriented clockwise.
