The Astronomical Bodies Rendering Application for Mission design is a validated physically-based render engine for planets, moons and small bodies.
Clone the repository and the linked submodules by running the following git commands:
git clone https://github.com/andrepiz/abram
git submodule init
git submodule update
Then, simply run the script call() to generate your first rendering. Check the ABRAM wiki to access the full documentation.
ABRAM has been developed and tested in MATLAB r2023b with the following dependencies:
- Image Processing Toolbox (required)
- Parallel Computing Toolbox (for multi-thread rendering)
- Statistics and Machine Learning Toolbox (for image noises)
If you use the tool, please cite it in your work as:
A. Pizzetti, P. Panicucci, F. Capolupo, F.Topputo. "Development and Validation of a Physically Based Rendering Methodology for Celestial Bodies". Under review.
ABRAM has been used in the following publications:
A. Pizzetti, P. Panicucci, F.Topputo. "A Bottom-Up Approach for Radiometric Validation of Synthetic Imagery". Inter-Agency GNC V&V Workshop (IAGNC 2025).
