  • Preserving Topology and Elasticity for Embedded Deformable Models - SIGGRAPH'09 Project webpage: In this paper we introduce a new approach for the embedding of linear elastic deformable models. Our technique results in significant improvements in the efficient physically based simulation of highly detailed objects. First, our embedding takes into account topological details, that is, disconnected parts that fall into the same coarse element are simulated independently. Second, we account for the varying material properties by computing stiffness and interpolation functions for coarse elements which accurately approximate the behavior of the embedded material. Finally, we also take into account empty space in the coarse embeddings, which provides a better simulation of the boundary. The result is a straightforward approach to simulating complex deformable models with the ease and speed associated with a coarse regular embedding, and with a quality of detail that would only be possible at much finer resolution.

  • Holons, Singularity and Topology Holons are wholes composed of hierarchic parts. The holon has a "self-assertiveness tendency" (wholeness) as well as an "integrative tendency"(part) .This duality is similar to the particle/wave duality of light. (Koestler, 1967). It's a interesting theory but how is that physically or energetically possible? In this movie a engineering concept is given how a single non-breakable membrane can create such holons, which are multi-layered topological spaces. This happens with a penetration process, called a pelastration. Holons are then sub-sets (entanglements, knotting) of the total membrane, and each type will have its unique structure and frequencies. They are like bells with a clapper and a cup. In topological holons a part of the neutral dynamic energy of the membrane is converted - locally - in specific "retarded" energy, which is structured in two parts ( which make a union of two parts but will act as a unity ).

  • Kabbalah explained in Topological way When we speak about Kabbalah we think of the Tree of Life. However the Tree is about the "manifested" Universe. The manifested world is - in Kabbalistic view - based on three voids (unmanifested) which come from The Absolute. The 3 voids (layers) are called Ain, Ain Soph and Ain Soph Aur. Laureyssens shows in this video how the Absolute can create these 3 voids, where in this first holon 22 sub-holons (sub-sets) can be created on each of it's voids and/or between the voids. Where each sub-holon will have it's specific vibration(s) depending of it's unique structure. That's like the 22 letters is the Hebrew alphabet. And in each of these 22 holons (letters, universes, frames of reference, ...) again 22 more complex sub-combinations can be made after five (Catalan) steps of combinations. By adding more and more layers - thus by having more complex holons - mass (weight) is increasing and parts of universal energy is locally stored. More complex holons - above a measuring threshold will be called "Matter", below that threshold it will be considered "Energy". This topologic approach is in the line of geometrical thinking of Riemann, Clifford and Einstein, but now - for the first time - explains how the emanation over the paths can happen, since the membrane is the mediator and because all holons and sub-holons are still membrane. In religious terms: God is everywhere and we are part of God.

  • Kabbalah, the Tree of Life topologically explained The central picture in Kabbalah is the Tree of Life containing 10 sefirot and 22 paths. This design was derived from concentric circles (The Bahir). The concept of the tree is to represent how universal energy (Kether) transforms into the World (Malkuth). The Tree is about the "manifested" Universe. which is in Kabbalistic view - based on three voids (unmanifested) which come from The Absolute. The 3 voids are called Ain, Ain Soph and Ain Soph Aur. Laureyssens shows in this video - in an engineering approach - how the Absolute (One) can self-create these 3 first voids by a type of universal coupling action of a Singularity (a non-breakable dynamic spherical Membrane), similar to Ouroboros, the snake that bite it's own tail. The action is a penetration, called a pelastration, that creates from parts of the 2D-surface locally a multi-layered (structured) 3D topological sub-set, called a holon. The holon is a local UNION of two membrane tubes, but acts like a UNIT, where it's three joined M-layers interact and exchange energies. Ain, Ain Soph and Ain Soph Aur are these M-layers in each of the four type of Kabbalistic worlds. The Tree can be seen as a union of dynamic multilayered tubes which start from one or more of the Ain-layers, and where these tubes - by progressing - receive more and more layers. The penetration through the Ain Soph layer by the three superior sefirot (together one three-layered tube) gives an extra cover over this tube with is then called Daath (the ...

  • Physics-Inspired Topology Changes for Thin Fluid Features SIGGRAPH 2010 paper: Physics-Inspired Topology Changes for Thin Fluid Features Chris Wojtan, Nils Thürey, Markus Gross, and Greg Turk Abstract: We propose a mesh-based surface tracking method for fluid animation that both preserves fine surface details and robustly adjusts the topology of the surface in the presence of arbitrarily thin features like sheets and strands. We replace traditional re-sampling methods with a convex hull method for connecting surface features during topological changes. This technique permits arbitrarily thin fluid features with minimal re-sampling errors by reusing points from the original surface. We further reduce re-sampling artifacts with a subdivision-based mesh-stitching algorithm, and we use a higher order interpolating subdivision scheme to determine the location of any newly-created vertices. The resulting algorithm efficiently produces detailed fluid surfaces with arbitrarily thin features while maintaining a consistent topology with the underlying fluid simulation. Paper PDF:

  • Character Motion Synthesis by Topology Coordinates (Eurographics 2009) In this paper, we propose a new method to efficiently synthesize character motions that involve close contacts such as wearing a T-shirt, passing the arms through the strings of a knapsack, or piggy-back carrying an injured person. We introduce the concept of topology coordinates, in which the topological relationships of the segments are embedded into the attributes. As a result, the computation for collision avoidance can be greatly reduced for complex motions that require tangling the segments of the body. Our method can be combinedly used with other prevalent frame-based optimization techniques such as inverse kinematics.

  • Topological Coverage of Unknown Environment by a Mobile Robot In applications such as vacuuming, cleaning and demining, a robot must cover an unknown surface. The robot accomplishes coverage of an unknown surface by visiting all reachable surfaces in the environment. The efficiency and completeness of coverage is improved by the construction of a topological map while the robot covers the surface. The topological map is a spatial representation of the environment constructed with information gathered by the robots sensors. Robot uses the constructed topological map to plan complete coverage paths. Existing methods generally use grid maps, which are susceptible to odometry error, inaccuracies in sensors and may require considerable memory and computation. Topological map is based on topological relationships between landmarks. Landmarks are represented by corners because they are naturally ocurring features of the environment. It is rather difficult to store information about what area the robot has covered. This difficulty in storing coverage information is overcome by embedding a cell decomposition within the map. Decomposition method uses the landmarks in the topological map as its cell boundaries. The cells are ideally suited to coverage by a simple zigzag path. Covering the envrionment robot detects new uncovered cells and updates the topological map. Robot moves from one cell to another until all surfaces are covered.
  • Non-homeomorphic Topological Spaces This clip shows two non homeomorphic topological spaces (a line segment and a circle). Proof: We have to show that there is no bi-continuos map from the line segment to the circle. If there was such a map we could remove a point of the line segment and the image of this point on the circle. The remaining pieces would then still be homeomorphic. On the other hand the first one has two components while the second one is still connected. Since connectedness is preserved by bi-continous maps we obtain a contradiction. Therefore a bi-continous map from the line to the circle can not exist. qed This Video was produces for a topology seminar at the Leibniz Universitaet Hannover. www-ifm.math.uni-
