Tutorial on the Octree Transfromer for shape generation

Octree Transformer for Autoregressive Shape Generation

This repository contains a Jupyter Notebook tutorial on the Octree Transformer for Autoregressive Shape Generation, based on the research paper by Gregor Kobsik, Moritz Ibing, and Leif Kobbelt at RWTH Aachen University. The tutorial provides a hands-on introduction to various aspects of the Octree data structure, its application in shape representation and generation, the Octree Transformer architecture, and compression techniques for managing the complexity of 3D tasks.

Octree Trasnformer: Autoregressive 3D Shape Generation

Tutorial Highlights

• Octree Data Structure and Its Applications: Gain insights into the Octree data structure and its significance in representing and generating complex shapes efficiently. Understand the advantages it offers in terms of compact representation and processing speed.

• Octree Transformer Architecture: Explore the Octree Transformer, a novel approach that employs the Transformer architecture for processing Octree-based inputs. Learn how the Transformer's attention mechanisms can be leveraged to handle hierarchical structures effectively.
