<h1>[name]</h1>
|
|
|
|
<p class="desc">
|
|
Represents a section bounded by a specific amount of half-edges. The current implmentation assumes that a face always consist of three edges.
|
|
</p>
|
|
|
|
|
|
<h2>Constructor</h2>
|
|
|
|
|
|
<h3>[name]()</h3>
|
|
<p>
|
|
Creates a new instance of [name].
|
|
</p>
|
|
|
|
<h2>Properties</h2>
|
|
|
|
<h3>[property:Vector3 normal]</h3>
|
|
<p>
|
|
The normal vector of the face. Default is a [page:Vector3] at (0, 0, 0).
|
|
</p>
|
|
|
|
<h3>[property:Vector3 midpoint]</h3>
|
|
<p>
|
|
The midpoint or centroid of the face. Default is a [page:Vector3] at (0, 0, 0).
|
|
</p>
|
|
|
|
<h3>[property:Float area]</h3>
|
|
<p>
|
|
The area of the face. Default is 0.
|
|
</p>
|
|
|
|
<h3>[property:Float constant]</h3>
|
|
<p>
|
|
Signed distance from face to the origin. Default is 0.
|
|
</p>
|
|
|
|
<h3>[property:VertexNode outside]</h3>
|
|
<p>
|
|
Reference to a vertex in a vertex list this face can see. Default is null.
|
|
</p>
|
|
|
|
<h3>[property:Integer mark]</h3>
|
|
<p>
|
|
Marks if a face is visible or deleted. Default is 'Visible'.
|
|
</p>
|
|
|
|
<h3>[property:HalfEdge edge]</h3>
|
|
<p>
|
|
Reference to the base edge of a face. To retrieve all edges, you can use the 'next' reference of the current edge. Default is null.
|
|
</p>
|
|
|
|
<h2>Methods</h2>
|
|
|
|
<h3>[method:Face create]( [param:VertexNode a], [param:VertexNode b], [param:VertexNode c] )</h3>
|
|
<p>
|
|
[page:VertexNode a] - First vertex of the face.<br />
|
|
[page:VertexNode b] - Second vertex of the face.<br />
|
|
[page:VertexNode c] - Third vertex of the face.<br /><br />
|
|
|
|
Creates a face.
|
|
</p>
|
|
|
|
<h3>[method:HalfEdge getEdge]( [param:Integer i] )</h3>
|
|
<p>
|
|
[page:Integer i] - The index of the edge.<br /><br />
|
|
|
|
Returns an edge by the given index.
|
|
</p>
|
|
|
|
<h3>[method:this compute] ()</h3>
|
|
|
|
<p>Computes all properties of the face.</p>
|
|
|
|
<h3>[method:Float distanceToPoint]( [param:Vector3 point] )</h3>
|
|
<p>
|
|
[page:Vector3 point] - Any point in 3D space.<br /><br />
|
|
|
|
Returns the signed distance from a given point to the plane representation of this face.
