Traditionally, shape transformation using implicit functions is performed in two distinct steps: 1) creating two implicit functions, and 2) interpolating between these two functions. We present a new shape transformation method that combines these two tasks into a single step. We create a

A method is presented for shape transformation in the plane. The primary strength of the proposed method over previous approaches for shape transformation is that our method can achieve shape transformation in a domain that can contain obstacles which are possibly in motion. A smooth

the algorithm can be used for finding a correspondence for shape transformation. After the two given polyhedra are being realized, it is easy to merge their vertex–neighborhood graphs into a common graph. This graph is then induced back onto the original polyhedra. The common vertex–neighborhood graph allows

transform. In order to solve the correspondence problem, we attach a descriptor, the shape context, to each point. The shape context at a reference point captures the distribution of the remaining points relative to it, thus offering a globally discriminative characterization. Corresponding points on two

The action of temperatures above 48°C. on the red cell is usually regarded as a classical example of the irreversible effects of injury, the lysis which follows being attributed to a surface membrane becoming permeable because its lipid components are melted or because its protein components become denatured. Recently it has been found that the effects are considerably more complex, and increasing emphasis is being placed on the role which fragmentation plays in the phenomenon of heat haemolysis. Ham, Shen, Fleming & Castle (1948) have pointed out that the frag-mentation which precedes haemolysis results in the cells of the system becoming more and more spherical, so that the extent to which each cell can swell before its surface is stretched becomes less and less, and the tonicity in which it haemolyses becomes greater and greater; when there is sufficient fragmentation, indeed, human red cells will haemolyse even in an isotonic medium such as plasma. The tonicity-volume relations of cells which have lost one or more of these fragments during heating to temperatures in the neighbourhood of 48°C, however, are substantially the same as those of intact cells (Ponder, 1948 a), and both cells and fragments show

Techniques that transform one two-dimensionaf image into another have gained widespread use m recent yeara. Extending these techniques to transform pairs of 3D objects, as opposed to 2D images of the objects, providea several advsntagea, including the ability to snimate the objects independently

The paper presents a method of expressing CST shapes pioneered by Kulfan into stan dard Bezier curves and surfaces. Out of the seven standard shape classes identified by Kulfan as representable using CST curves, four of them, including airfoils, can be repre sented as Bezier curves exactly

A new technique is presented for computing transformations between polyhedral objects. Here, the correspondence and the interpolation problems are considered jointly. The approach gives the animator high level control of the shape transformation by providing natural specification and interaction.
