[name]
A geometric triangle as defined by three vectors.
Constructor
[name]( [page:Vector3 a], [page:Vector3 b], [page:Vector3 c] )
a -- [page:Vector3]
b -- [page:Vector3]
c -- [page:Vector3]
Sets the triangle's vectors to the passed vectors.
Properties
[property:Vector3 a]
The first [page:Vector3] of the triangle.
[property:Vector3 b]
The second [page:Vector3] of the triangle.
[property:Vector3 c]
The third [page:Vector3] of the triangle.
Methods
[method:Triangle setFromPointsAndIndices]( [page:Array points], [page:Integer i0], [page:Integer i1], [page:Integer i2] ) [page:Triangle this]
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.
[method:Triangle set]( [page:Vector3 a], [page:Vector3 b], [page:Vector3 c] ) [page:Triangle this]
a -- [page:Vector3]
b -- [page:Vector3]
c -- [page:Vector3]
Sets the triangle's vectors to the passed vectors.
[method:Vector3 normal]( [page:Vector3 optionalTarget] )
optionalTarget -- Optional [page:Vector3] target to set the result.
Return the calculated normal of the triangle.
[method:Vector3 barycoordFromPoint]( [page:Vector3 point], [page:Vector3 optionalTarget] )
point -- [page:Vector3]
optionalTarget -- Optional [page:Vector3] target to set the result.

[method:Triangle clone]()
Return a new copy of this triangle.
[method:Float area]()
Return the area of the triangle.
[method:Vector3 midpoint]( [page:Vector3 optionalTarget] )
optionalTarget -- Optional [page:Vector3] target to set the result.
Return the midpoint of the triangle. Optionally sets a target vector.
[method:Boolean equals]( [page:Triangle triangle] )
triangle -- [page:Triangle]
Checks to see if two triangles are equal (share the same vectors).
[method:Plane plane]( [page:Plane optionalTarget] )
optionalTarget -- Optional [page:Plane] target to set the result.
Return a [page:Plane plane] based on the triangle. Optionally sets a target plane.
[method:Boolean containsPoint]( [page:Vector3 point] )
point -- [page:Vector3]
Checks to see if the passed vector is within the triangle.
[method:Vector3 closestPointToPoint]( [page:Vector3 point], [page:Vector3 optionalTarget] )
point -- [page:Vector3]
optionalTarget -- Optional [page:Vector3] target to set the result.
Returns the closest point on the triangle.
[method:Triangle copy]( [page:Triangle triangle] )
triangle -- [page:Triangle]
Copies the values of the vertices of the passed triangle to this triangle.
