Stereoscopic image quality in virtual environments

publications

Abstract: The number of products capable of displaying stereoscopic (also known as 3D) images has been growing in recent years. The use of this technology has outgrown the silver screen and is now available in televisions, computers, tablets, and even cell phones. Due to its nature, content created for stereoscopic media requires attention in relation to some characteristics not present in the context of monoscopic media. With a focus on image creation, the objective of this research was to assess how different stereoscopic image generation methods can affect human perception. To achieve this a virtual environment was created and from it different videos were generated using various methods including converging cameras, parallel cameras, and depth image-based rendering (DIBR). These videos were shown to participants who assessed the picture quality, depth quality, and visual comfort of the media. It was found that there was very little difference between the perception of images generated by parallel and convergent cameras, while there was a substantial difference in terms of perception between these two types of image and DIBR images. Such results can significantly affect the choice of technology for stereoscopic image generation, influencing the production costs, the methods involved, and human and machine time consumption.

Island Adventures

publications

Cross-media adaptation

Dias Velho e os Corsários (1988) is a Graphic Novel, written and illustrated by Eleutério Nicolau da Conceição, which depicts a pirate invasion to the island of Santa Catarina in the 17th century. Using a historic event as inspiration the work successfully represents local themes such as culture and social organization. The audience to which the publication was originally targeted (13+) allowed the story to be represented in a realistic manner, with complex characters and episodes of violence and death. This work details the adaptation of such story to the media of animation and a significantly younger audience (pre-schoolers).

Citroen Aircross

professional work

This last job I’ve participated in was of a very rare breed. Animaking was bold enough to mix a bunch of different techniques, namely live action, miniature models, stop motion, cg and post… phew. It all blends into a nice view of the Aircross automobile running through the atacama desert…

I was a small part of this great effort, running most particle sims. It was very nice to work with some old friends and meet a few more nice people.

Watch in HD, if you will…

workshop

training

Back from the metropolis! This past week I have presented a workshop on ICE for 40 people at Melies school of cinema and animation, in São Paulo. Those who attended got a clear idea of what a interactive visual programing envoiroment like ICE may bring to the table in the context of animation and effects. We also stablished a panorama of most type of sims that exist in this, and other plataforms, trying to understand the pros and cons of each. Besides this overview we got into the guts of all the math behind ICE and some things those who are not aquinted with the tool get a hard time with (like data’s type and context). To finish it all off tornados and explosions were simulated, good times!

Motion Tools

research and development

Motion Tools is a small collection of tools that aims to aid Motion Graphic work being created inside Softimage. It does so by providing many ICE compounds and partially abstracting the ICEtree construction processes. It eases the creation, procedural animation and simulation of many many objects or chunks of geometry.
