Dr.TVAM¶

Dr.TVAM is an inverse rendering framework for tomographic additive manufacturing. It provides a set of tools to model a TVAM printing process and optimize projection patterns for it. It is implemented in Python on top of the Mitsuba 3 framework.

It is possible to use Dr.TVAM to setup a wide variety of experiments. In particular, we support:

Printing in scattering media.
Printing with arbitrary container geometry (round, square, …), or occluding objects (e.g. overprinting), with correct handling of the light transport.
Printing with a variety of projection models, and an arbitrary container motion.
Optimizing patterns for TVAM with our surface-aware discretization.
High-performance, see also Performance Tips

Installation¶

We recommend installing Dr.TVAM directly with pip:

pip install drtvam

Or the current development version with pip:

pip install https://github.com/rgl-epfl/drtvam

Alternatively, you can clone the repository and install it manually:

git clone --recursive git@github.com:rgl-epfl/drtvam.git
pip install ./drtvam

Requirements¶

Python >= 3.8
A NVIDIA GPU with driver version >= 495.89
Alternatively, to use Dr.TVAM on the CPU: LLVM >= 11.1. The performance will be significantly lower than on the GPU, however.

Getting started¶

Dr.TVAM is a python-based framework that allows great flexibility in setting up an inverse optimization for TVAM. We also provide a command-line tool to run an optimization from a configuration file. We detail the how to use it in the Basic Usage section.

For more advanced usage of Dr.TVAM, it is possible to implement one’s own optimization pipeline. We provide a set of tutorials to explain the key concepts in the Tutorials section.
