A Survey on Position Based Dynamics
Bender, Jan; Müller, Matthias; Macklin, Miles
Adrien Bousseau and Diego Gutierrez
The physically-based simulation of mechanical effects has been an important research topic in computer graphics for three decades. In recent years position-based simulation methods have become popular. In contrast to classical approaches these methods compute the position changes in each simulation step directly, based on the solution of a quasi-static problem. Therefore, position-based approaches are fast, stable and controllable which make them well-suited for use in interactive environments. However, these methods are generally not as accurate as force-based methods but provide visual plausibility. Hence, the main application areas of position-based simulation are virtual reality, computer games and special effects in movies and commercials.

Partitioning Surfaces into Quad Patches
Campen, Marcel
Adrien Bousseau and Diego Gutierrez
The efficient and practical representation and processing of geometrically or topologically complex shapes often demands some form of virtual partitioning into pieces, each of which is of a simpler nature. Due to their regularity, highly structured networks of conforming quadrilateral patches, called quad layouts, or in particular instances quad meshes, are most beneficial in many scenarios; they enable the use of tensor-product representations based on NURBS or Bézier patches, grid-based multiresolution techniques, or discrete pixel-based map representations. However, partitions of this type are particularly complicated to create due to the inherent structural restrictions. Research in geometry processing has led to a variety of automatic or semi-automatic approaches to address this problem. This course provides a detailed introduction to this range of methods, treats their strengths and weaknesses, discusses their applicability and practical limitations, and outlines open problems in this field.

Mobile Graphics
Agus, Marco; Gobbetti, Enrico; Marton, Fabio; Pintore, Giovanni; Vázquez, Pere-Pau
Adrien Bousseau and Diego Gutierrez
The increased availability and performance of mobile graphics terminals, including smartphones and tablets with high resolution screens and powerful GPUs, combined with the increased availability of high-speed mobile data connections, is opening the door to a variety of networked graphics applications. In this world, native apps or mobile sites coexist to reach the goal of providing us access to a wealth of multimedia information while we are on the move. This half-day tutorial provides a technical introduction to the mobile graphics world spanning the hardware-software spectrum, and explores the state of the art and key advances in specific application domains, including capture and acquisition, real-time high-quality 3D rendering and interactive exploration.

Computer Generated Display Holography
Lobaz, Petr
Adrien Bousseau and Diego Gutierrez
« A hologram » is a ubiquitous term when talking about realistic 3-D illusion. « Holographic display » seems to be the holy grail of 3-D display technology, at least according to news headlines. But what « holographic » actually means? The tutorial explains basics of holography, the lensless imaging method, invented by Gabor and Denisyuk in the mid-twentieth century, that produces breathtaking 3-D images - holograms. Then it explains basic steps of transition from classical to digital holography and to computer generated display holography - a counterpart of computer graphics that does not calculate an image, but a hologram. The tutorial also covers holographic printing, holographic electronic displays and compares them to competing technologies.
