	UDN - Two - ShapeEditor
		The edges of the shape are in a way the lines that join the vertices together, and the flat area bounded by a set of edges is a face.
		The shape can be extruded, which simply means that the exact shape is created in the brush, but it is extended directly back to form the third dimension.
		Extruding the shape to a bevel will result in a brush similar to the one that is extruded to a point, but one that is cut off before it reaches the point.

		Objects which are geometrically similar either have the same shape or one has the same shape as the other's mirror image (or both if they are themselves symmetric).
		The modern definition of shape has arisen in the field of statistical shape analysis.
		In particular Procrustes analysis, which is a technique for analysing the statistical distributions of shapes.

		We present an algorithm for learning the time-varying shape of a non-rigid 3D object from uncalibrated 2D tracking data.
		We model shape motion as a rigid component (rotation and translation) combined with a non-rigid deformation.
		We constrain the problem by assuming that the object shape at each time instant is drawn from a Gaussian distribution.

		The depiction of the 2D projection C' of the 3D shape C with respect to the depiction of the 2D shapes A and B depends upon the relative position of the 3D shape C along the Z coordinate axis.
		The 2D projection D' of the 3D shape D will appear to be overlapped by the 2D shape A on the projection plane 102, in accordance with the invention.
		Since the 2D projection C' of the cubic shape C is drawn at a time later than the drawing of the 2D shapes A and B, the 2D projection C' is shown to overlap the 2D shapes A and B on the projection plane 102, as is desired.

		In addition, 2D polygons serve as cheap mesh, which is a slang term for an object that has a low polygon count or is very efficient and quick to render.

	Describing 2D Shape With Extended Polygon Boundaries
		Primitive shape is expressed at the level of boundary elements, which are either qualitatively homogeneous segments of the boundary, or the junctions between those segments.
		This shape representation does not make any use of axes, and it provides no space filling information of the type that is provided by the subparts or imples of the ASSF representation.
		As a subset, the basic shape representation of the EPB technique is therefore simpler, but less intuitively obvious to humans than the hierachy of subparts and features.

		The challenge is to understand iteration objects, which are individual instances of lines and curves (specifically, quadratic and cubic Bezier splines) that describe the connecting paths encountered as you move (iterates) around the boundary of a geometric object.
		As such, all geometric shapes, including rectangles and arcs, can be specified the long way; that is, by creating series move and draw commands.
		When the shape is simple and has edges that intersect only at the vertices (such as a rectangle or circle) the problem is trivial.

		Needless to say, this is built entirely with the 2D shape editor.
		This technique also leads to a lot of brush scaling too, because when you use the 2D shape editor, you can't relate the size of a shape to the rest of your map and some people are too lazy to modify the whole shape to make it smaller so they just scale the brush down.
		Of course, I'm not saying never use the 2D shape editor, it does have it's uses, but the more you get used to using alternative and quicker methods, the less and less you will have to use it.

		Given two parallel lines, both tangent to the shape at any two given distinct points on "opposite" sides, they will always be of the same distance apart.
		The simplest form of this interesting shape, shown above, can be constructed by starting with an equilateral triangle and then drawing arcs with radii equal to the sides, centered at the vertices and just outside the opposite edge, intersecting and terminating at the two ends of the edge, i.e.
		In this case, the radii of the arcs, or rather the width of the shape, are equal to the distance from any given vertex to the farthest of the other vertices.

	Flux Invariants for Shape (Site not responding. Last check: 2007-10-21)
		We consider the average outward flux through a Jordan curve of the gradient vector field of the Euclidean distance function to the boundary of a 2D shape.
		Using an alternate form of the divergence theorem, we show that in the limit as the area of the region enclosed by such a curve shrinks to zero, this measure has very different behaviours at medial points than at non-medial ones, providing a theoretical justification for its use in the Hamilton-Jacobi skeletonization algorithm of [SBTZ].
		Thus this measure can be viewed as a Euclidean invariant for shape description: it can be used to both detect the skeleton from the Euclidean distance function, as well as to explicitly reconstruct the boundary from it.

		Explain what classification means and how it is used in other areas such as language arts, science, art, verb conjugation etc. This can be done in parts, for example, you can classify the shapes in one or two lesson formats and then use Inspiration during the next two lesson formats.
		Extension: Once classification is complete and the students are familiar with Inspiration to categorize 2D shapes, you could then create an extension of how to use Filemaker Pro or some other database program to accomplish the same task.

		The main difference from previously reported methods is that the training set is first automatically clustered and those shapes considered to be outliers are discarded.
		A quantitative analysis of our shape registration approach within the main cluster of each structure, shows that our results compare very well to those achieved by manual registration; achieving an average rms error of about 1 pixel.

	2D Shape Blending Based on Artist-Specified Line Segments (Site not responding. Last check: 2007-10-21)
		Polygon blending is usually considered a two-part process: generating vertex mappings and interpolating mapped vertices to create the intermediate polygons; vertex mappings affect the results more strongly.
		Currently many 2-D shape-blending methods often can’t produce satisfactory intermediate shapes when source and destination shapes are dissimilar, and there are no good ways for artists to control the transformation.
		It provides the animator complete control over the transformation and generate pleasant metamorphosis results with artist-control of a morph even if source and destination shapes are dissimilar.

	Antialiasing, images, and alpha compositing in Java 2D
		Aliasing occurs when a signal (in this case, a 2D graphics signal) is sampled and quantized from a continuous space into a discretized space.
		Java 2D lets you set one of several rendering hints to indicate that you would like for your 2D graphics to be drawn using antialiasing algorithms -- which smoothes the edges.
		Note that I said hints: Whichever Java 2D implementation you're using, it is allowed to decide whether or not to follow the hint and carry out the antialiasing as requested.
