- <h1>[name]</h1>
- <p class="desc">
- A class containing utility functions for shapes.<br /><br />
- Note that these are all linear functions so it is necessary to calculate
- separately for x, y (and z, w if present) components of a vector.
- </p>
- <h2>Methods</h2>
- <h3>[method:Number area]( contour )</h3>
- <p>
- contour -- 2D polygon. An array of THREE.Vector2()<br /><br />
- Calculate area of a ( 2D ) contour polygon.
- </p>
- <h3>[method:Boolean isClockWise]( pts )</h3>
- <p>
- pts -- points defining a 2D polygon<br /><br />
- Note that this is a linear function so it is necessary to calculate
- separately for x, y components of a polygon.<br /><br />
- Used internally by [page:Path Path], [page:ExtrudeGeometry ExtrudeGeometry] and [page:ShapeGeometry ShapeGeometry].
- </p>
- <h3>[method:Array triangulateShape]( contour, holes )</h3>
- <p>
- contour -- 2D polygon. An array of [page:Vector2].<br />
- holes -- An array that holds arrays of [page:Vector2]s. Each array
- represents a single hole definition.<br /><br />
- Used internally by [page:ExtrudeGeometry ExtrudeGeometry] and
- [page:ShapeGeometry ShapeGeometry] to calculate faces in shapes with
- holes.
