Description of pipeline

Images are rendered in blender at high resolution (~25kx25k). The montaged micrograph is imported as a tiff texture and molecules are imported using Molecular Nodes.
- Every dataset is one scene in the blenderfile. The micrograph and molecular overlay layers are ViewLayers within the scene. The compositor is used to save them all into seperate files.
- There is a custom renderscript that uses renderregions to break the rendered image up into 4 quadrants. Otherwise the compositor crashes even on machines with a lot of RAM (512GB).
- The orthographic scale of the camera is driven by a driver based on the render resolution. That ensures a constant pixel-size.
- The rendered quadrants are placed into a folder called "output"
- An example .blend file with the nescessary data can be downloaded here
The script assemble_dzi.py is used to assemble the quadrants and then write out image pyramids in dzi format.
The script optimize_png.sh is used to optimize the filesize of the dzi image pyramid (from ~1GB to 250MB)
The resuting dzi files are uploaded to a static hosting service.
The webapp in this repo can read specifications in json format to display the dzi files. Example

pnpm install

pnpm dev

pnpm build

pnpm lint
