Compression, Streaming, Vidéo 3D

Objectives

- Know the different representations of 3D models: discrete models, with or without topology, parametric and/or implicit continuous models.
- Implement a compression algorithm for a 3D model in order to transmit it.
- Implement interactions in a 3D world.

Description

The part on 3D representations is a suite of 5CTD. For each course, a 45mn lecture presenting a 3D model is proposed, then, each group presents a research paper which proposes a 3D model of the studied type.

Course 1: discrete surface models

Course 2: discrete volume models

Lecture 3: subdivision models

Lecture 4: parametric representations

Course 5: implicit representations

TP / Project: a context of transmission of a file and its progressive decoding

Each group chooses an article that proposes a progressive representation of a 3D model and implements this model to progressively transmit 3D objects in the proposed context.

Interaction in 3D: A 2-session javascript lab allows to implement interactions in a 3D scene.

Beyond these 'classical' books, we study more advanced research articles.

Pre-requisites

The prerequisite for the 3D modeling part is to know basic parametric curve and surface models, such as curves or Bézier surfaces.
