Master internship : VR for artistic work visualization

We are looking for a highly motivated Master student for a research internship.

  • Keywords: realtime rendering, virtual reality, art work visualization
  • Advisor: David Vanderhaeghe, Toma Popovici
  • Location: Laboratoire IRIT, équipe VORTEX (Groupe AGGA), Université Paul Sabatier – Toulouse
  • Duration: from February/March 2017, 5-7 months

The internship will take place in the IRIT laboratory, on the Université Paul Sabatier, campus of Toulouse.
The recruited intern will be a full member of the research team, integrated with other team members, PhD students and permanent researches. He/she will participate to working groups, scientific seminars and other activities of our group.

Context

Public access to art and culture is a major issue in our society.
Many collections, paintings for example, travel around the world to be exhibited in the biggest museums.
However, certain artistic works are difficult to transport, in relation to their size, their installation or their fragility.

In our case study, the observers come even inside the art-piece, and because they can’t resist touching the paint, it is prone to premature wear.

Also, in order to allow the greatest number of people to benefit from the art works without incurring transport costs or risks to the integrity of the art work, we wish to develop a process of acquisition and visualization of art works in virtual reality.

Objectives

The objective is to develop a 3D display system, with virtual reality device, allowing to reproduce the installation of Toma Popovici (see Fig. below), consisting of paintings for a total of 150 meters long and 1.5 meters height forming a labyrinth where the public goes through.

The different steps envisaged are:

  • Acquisition and preparation of data, test on a sub-set
  • Creating a sample scene
  • 3D display and validation with the artist on rendering quality
  • Complete data acquisition
  • Creation of an ad-hoc 3D modeling tool
  • VR display and validation with the artist

Student profile

  • Master student in Computer Science or Applied Mathematics
  • Strong programming skills (C++), GPU programming (OpenGL)
  • Basic knowledge on linear algebra and optimization algorithms
  • Basic knowledge on Unity, C#,
  • Fluent English or French spoken

Master Internship : Path space analysis for user control

We are looking for a highly motivated Master student for a research internship.

  • Keywords: User Control of Rendering, Path Tracing, Ray Tracing, Computer Graphics
  • Advisor: David Vanderhaeghe
  • Location: Laboratoire IRIT, équipe VORTEX (Groupe AGGA), Université Paul Sabatier – Toulouse
  • Duration: from February/March 2017, 5-7 months

The internship will take place in the IRIT laboratory, on the Université Paul Sabatier, campus of Toulouse.
The recruited intern will be a full member of the research team, integrated with other team members, PhD students and permanent researches. He/she will participate to working groups, scientific seminars and other activities of our group.

Context

Physically based rendering, using path-space formulation of global illumination, has become a standard technique for high-quality computer-generated imagery. Nonetheless, being able to control and edit the resulting picture so that it corresponds to the artist vision is still a tedious trial-and-error process.  We introduce portals as a path-space manipulation tool to edit and control renderings and show how our editing tool unifies and extends previous work on lighting editing. Portals allow the artist to precisely control the final aspect of the image without modifying neither scene geometry nor lighting setup. According to the setup of two geometric handles and a simple path selection filter, portals capture specific lightpaths and teleport them through 3D space.

Here is the publication

Objectives

In this context, we are interested in a better understanding of the ray statistics that are meaningful to decompose an image. The project is to analyze data from ray paths computed by a bi-directional path-tracer and to segment rays in a set of perceptually motivated layers.

We also propose to extend portals to better behave with forward path tracer.
