Two Minute Papers – Manipulating Photorealistic Renderings

Photorealistic rendering (also called global illumination) enables us to see how digital objects would look like in real life. It is an amazingly powerful tool in the hands of a professional artist, who can create breathtaking images or animations with. However, for the longest time, artists didn’t use it in the movie industry because it […]

Two Minute Papers – Digital Creatures Learn To Walk

In this episode, we are going to talk about computer animation, animating bipeds in particular. If we have the geometry of a creature, we need to specify the bones, the muscle routings and the muscle activations to make them able to walk. Depending on the body proportions and types, it may require quite a bit […]

Two Minute Papers – Hydrographic 3D Printing

3D printing is a technique to create digital objects in real life. This technology is mostly focused on reproducing the digital geometry itself – colored patterns (textures) still remains a challenge, and we only have very rudimentary technology to do that. Hydrographic printing on 3D surfaces is a really simple technique: you place a film […]

Two Minute Papers – Deep Neural Network Learns Van Gogh’s Art

Artificial neural networks were inspired by the human brain and simulate how neurons behave when they are shown a sensory input (e.g., images, sounds, etc). They are known to be excellent tools for image recognition, any many other problems beyond that – they also excel at weather predictions, breast cancer cell mitosis detection, brain image […]

Two Minute Papers – Time Lapse Videos From Community Photos

Building time lapse videos from community photographs is an incredibly difficult and laborious task: these photos were taken at a different part of the year, from different times of the day, with different viewpoints and cameras. A good algorithm should try to equalize these images and bring them to a common denominator to get rid […]

Two Minute Papers – Simulating Breaking Glass

Time to smash virtual objects in slow motion! There is something inherently exciting about watching breaking glass and other objects. Researchers in computer graphics also like to have some fun and write simulation programs to smash together a variety of virtual objects in slow motion. However, despite being beautiful, they are physically not correct as many […]

Two Minute Papers – Artificial Neural Networks and Deep Learning

Artificial neural networks and deep learning provide us incredibly powerful tools in machine learning that are useful for a variety of tasks ranging from image classification to voice translation. So what is all the deep learning rage about? The media seems to be all over the newest neural network research of the DeepMind company that […]
