A geometric triangle as defined by three [page:Vector3 Vector3s] representing its three corners.

[page:Vector3 a] - the first corner of the triangle. Default is a [page:Vector3] at (0, 0, 0).

[page:Vector3 b] - the second corner of the triangle. Default is a [page:Vector3] at (0, 0, 0).

[page:Vector3 c] - the final corner of the triangle. Default is a [page:Vector3] at (0, 0, 0).

Creates a new [name].

The first corner of the triangle. Default is a [page:Vector3] at (0, 0, 0).

The second corner of the triangle. Default is a [page:Vector3] at (0, 0, 0).

the final corner of the triangle. Default is a [page:Vector3] at (0, 0, 0)

Returns a new triangle with the same [page:.a a], [page:.b b] and [page:.c c] properties as this one.

[page:Vector3 point] - [page:Vector3]

[page:Vector3 target] — the result will be copied into this Vector3.

Returns the closest point on the triangle to [page:Vector3 point].

[page:Vector3 point] - [page:Vector3] to check.

Returns true if the passed point, when projected onto the plane of the triangle, lies within the triangle.

Copies the values of the passed triangles's [page:.a a], [page:.b b] and [page:.c c] properties to this triangle.

Returns true if the two triangles have identical [page:.a a], [page:.b b] and [page:.c c] properties.

Return the area of the triangle.

[page:Vector3 point] - [page:Vector3]

[page:Vector3 target] — the result will be copied into this Vector3.

Return a [link:https://en.wikipedia.org/wiki/Barycentric_coordinate_system barycentric coordinate]
from the given vector.

[page:Vector3 target] — the result will be copied into this Vector3.

Calculate the midpoint of the triangle.

[page:Vector3 target] — the result will be copied into this Vector3.

Calculate the [link:https://en.wikipedia.org/wiki/Normal_(geometry) normal vector] of the triangle.

[page:Plane target] — the result will be copied into this Plane.

Calculate a [page:Plane plane] based on the triangle. .

[page:Box3 box] - Box to check for intersection against.

Determines whether or not this triangle intersects [page:Box3 box].

Sets the triangle's [page:.a a], [page:.b b] and [page:.c c] properties to the passed [page:Vector3 vector3s].

Please note that this method only copies the values from the given objects.

points - [page:Array] of [page:Vector3]s

i0 - [page:Integer] index

i1 - [page:Integer] index

i2 - [page:Integer] index

Sets the triangle's vectors to the vectors in the array.
