Hey everyone,<\/p>\n
Ihave been working on a project to bridge the gap between 3D rendering and aerospace computer vision. I built a fully headless Python-Blender rendering architecture to procedurally generate physically accurate synthetic data for asteroids.<\/p>\n
The pipeline automates the extraction of:<\/p>\n
- \n
- Multi-pass EXR renders (RGB, Z-Depth, Camera-Space Surface Normals and many more optional passes)<\/li>\n
- Photometric lightcurve CSVs (tracking total flux, projected area, mean depth, and sun\/observer coordinates per rotational step)<\/li>\n
- Procedural material setups for both uniform and variable regolith albedos.<\/li>\n<\/ul>\n
I have open-sourced a sample dataset of 600 meshes and their corresponding lightcurves on Kaggle for anyone who wants to train photometric inversion or pose estimation models.<\/p>\n
Basically I wanted to research on the effects of albedo variation comapred to uniform asteroid. So what I did was took real asteroid meshes from DAMIT (coverted it to obj files), created a fully procedural and realistic shader applied it on the meshes and rendered a full revolution of asteroid in simulated space conditions. To acheive this, in result, I build a full headless python pipeline that does the complete job, with all the optimization I could do in the world, and even with my old GTX 970, the render time was insanely good. The pipleline automatically creates the lightcurve csv files (with multiple phase angles ) and with all the physics data as well such as normals and depth so I can have the option to train PINN model as well. However I have my exams so had to stop here. <\/p>\n
That being said, <\/p>\n
If you need massive scale or want to generate your own data locally, I have also packaged the full 3,000+ mesh dataset (6000 light curves) and the actual Python\/Blender codebase (the Pipeline Toolkit).<\/p>\n

Note:<\/strong> If you are a student or independent researcher who really needs this data but cannot afford the Gumroad tier, hit me up via DM. I will be happy to arrange a free, expanded subset of the data to support your work.<\/p>\n
Disclaimer (per Rule 1): I am the creator of this pipeline and the Gumroad links go to my own store, StellarMesh Labs.<\/p>\n<\/div>\n
