Fields part II: Morpher/BlendShapes

Saturday, January 28, 2012 § 5

Morphing, is the technique where a transition between two images is achieved seamlessly. The technique was (of course) developed initially for cinematographic purposes. As we read on filmsite.org, the first time it was used extensively was in the movie the willow, in 1988. One of the most impressive early movie examples was in Terminator 2: the judgment day. There the T-1000 cyborg terminator was equipped with the ability to morph into any kind of object (it was actually supposed to be made out of a morphing metal); the running time of the morphing scenes are counting up to 16mins (again according to filmsite.org). A very interestin example in the arts is the work of Daniel Lee and more specifically his 1993 manimal series (from these series Ben van Berkel and Caroline Bos are using the "year of the ox" in order to explain their 'hybrid building' concept). Of course, 3D motion effects could not stay out of the game in such a case. Most 3D packages today include tools able to transform seamlessly one piece of geometry into another (morphing or blend shapes). 3D morphing is based on the position of vertices of the objects. There is a base object (the one being animated) and one or several targets. The vertices of the base object are interpolated on paths created between the initial position of the vertices in the base object and the position of the vertices in the target objects.

The base concept behind 3D morphing however, while applied extensively in computer animation, is not that new. In ~1480, painter Piero della Francesca publishes his third book De Prospectiva Pingendi where he deals with the 3-dimentional representation of objects. As we read on this article, the book is composed out of three chapters: The first deals with the projection of 2-dimentional shapes and the second extends that to the projection of 3-dimentional shapes. The third chapter however appears to be the most interesting: there he describes what he calls 'The other method'. This 'other method' (meaning 'not Alberti's perspective method') is illustrated through drawings that are explaining how it can be used in order to represent a human head: First he draws cross-sections from top to bottom and then axial sections from the center of the head. The intersection of the two sets of sections, gave him 128 points positioned around the human head. All this process is already amazing considering the time that it was made, but the really amazing part comes next: Piero della Francesca was able to use those points and their relations in order to rearrange them and subsequently in order to be able to draw any other posture of the human head, in essence achieving auxiliary projection some hundreds of years before that was actually invented by Gaspard Monge. On a first note this is a great example of how one can shift from a representational method to a generative one. The representation of the intersection points of the two sets of sections, becomes a generative tool that allows the creation of any other position of the head.

Considering the relation with morphing, while Piero della Francesca's 'other method' is not exactly the same as contemporary morphing techniques, the similarities are nevertheless still striking: both methods are using points (the intersection points in the first case, the vertices in the second) strategically positioned on a surface that through their relative positions can be used in order to represent several other 'incarnations' of the surface.

When coming to initial contemporary practices in 'digital' architecture, morphing had a critical role. One of the main reasons was that morphing made possible explorations of the topological transformations of an object. Now, topology is a rather over - and extensively mis - used term in architectural cycles. It was used heavily in order to denote any kind of computer generated, curved form, the same way 'blobs' were used before that and 'parametric' is used now. We all have heard more than enough times how topology is an alternative to Euclidian geometry, meaning in essence curved forms vs rectilinear forms. For better or for worst though, topology has nothing against Euclidian geometry, since topology is not a different geometry at all (at least not in the sense that Riemannian geometry for example is); on the contrary, most topological studies remain within the Euclidian 'field'. Euclidian - or for that matter any kind of - geometry is studying the state of an object. Topology however is concerned with the transformations of an object. In other words, there is no such thing as a topological surface or object. The only thing that can be topological is a transformation. If we were to over-simplify, geometry is quantitative - the sizes of an object is what matters - topology is qualitative - it is connectivity, continuity and convergence that matters -. In short, the topology of an object is preserved when that object goes through continuous deformations. On the other hand the topology of an object changes if for example a new hole is introduced to it. Therefore, morphing is concerned exactly with that aspect: the way an object is transformed continually, moving from one geometrical shape to another while keeping its topology the same.

And this is the point where topology becomes a very useful concept in architecture today, and morphing a very useful tool that helps to study that concept. Because, if we were to abstract the principles of topological thinking, we could see that is not the state of an object that matters but the transformations that it goes through. Or, if we were to take that in a more philosophical level, we don't care so much about the being of an object, or whatever it is that we are studying, but we focus instead on the becoming of an object. If we consider the classic example of a cube morphed into a sphere, it is not really the sphere or the cube that we care about; it is the cube becoming a sphere - or the sphere becoming a cube - that is of interest (as in Terminator 2: it is not T-1000 as a human or T-1000 as a small lake of liquid metal that has an impact on us; it is the small lake of metal in a state of becoming human that is the most frightening). Consequently, identity is defined through difference: it is not what something is, but what something is in the process of becoming that matters, and therefore the differences between the stages of the transformation are the ones that are helping us identify it as the same object. On a different level, topology can help us understand a little better - or see from a different view - the difference between constants and variables; what are the things that have to remain the same and what are the things that can change values, in order for something to keep its identity.

During the last six years I have been working quite a lot with blend shapes and morphers, as a useful tool to study the above, and therefore developed several simple tools to help me deal with morphing. My main aim was to have tools that would allow me to use the different (but topologically equal) version of an object all at the same time, in the context of a field (see this post for more on fields). The concept for all of them is simple: an array of one object that gets locally differentiated according to specific factors. As a side note, all of them are more like a base to expand upon than fully developed tools.
1. surfaceBlendShapeField.ghx: this is a grasshopper definition that takes the idea of a blend shape and distributes it in a field. The local differentiation is based on the distance of each element from point or/and curve attractors. Quite primitive in relation to the next ones, but it can be easily expanded.
2. morphField_v1.ms: This is the same idea implemented in maxscript and it is much more robust than the rest. It is installing expressions that are controlling the value of a morphed target in all the objects of the field.

3. blendShapeFieldWithAttractors_v1.mel: this is the exactly the same as the above, only that it is implemented in mel for maya. Also, it is a little bit less user-friendly than the maxscript version - as is always the case with maxscript vs mel for me.

4. fluidsToBlendShapes.mel: This is a similar idea, implemented in mel, only that it is not using points to drive the blendShapes, but the density of maya fluids, which can give some very interesting results. Both mel scripts were initially written for the SKG in flux workshop that took place in 2009 with some minor updates added to them later. This an animation produced with the last script during the workshop:

SOPA Black Out.

The internet is based on protocols. Protocols are the means to control. SOPA/PIPA bills are taking control from the users transfering it over to centralized places of power. Therefore, they are threatening the very existence of the net as we know it.
