Python Package for Generative Systems and Sciences

topoGenesis

topoGenesis is an open-source python package providing topological data structures and functions for working with voxel data in Generative Systems and Sciences. The envisaged application areas are:

• generative design in architecture and built environment
• generative spatial simulations
• 3D image processing
• topological data analysis
• machine learning

Vision

topoGenesis aims to utilize the vast functionalities of fields (mathematical objects) in generative systems and sciences. Therefore it seeks to:

1. offer basic mathematical functionalities on field data models
2. offer functionalities of computational topology on top of the field structures
3. facilitate the conversion between mesh-based data models and field data models.
4. facilitate field simulations, whether governed by differential equations, spectral models or based on computational models (ABM)
5. construct a bridge between spatial data models and tensor data structures to facilitate the utilization of the latest artificial intelligence models

topogenesis's Issues

Read the docs links dont work

When I try to go and look at the read the docs and click one of the contents. I have a time out error. So can't really evaluate the library.

How to transform np array to tg array/lattice

When working in tg we want to use previously generated data of the type np array to "find_neighbours", but this returns the error of wrong data input. We now want to transform the np array into a tg lattice, but cannot find how to do this.

Reading exported .csv files

For some reason loading in .csv files that do not have a "True" or "False" set as their 'value' (fourth entry), but instead a 1 or 0 or a float value are loaded in incorrectly with the topogenisis lattice_from_csv command.

For instance the solar_envelope_324 file is supported, but the sun_access file isn't.

As you can see the shape of the sun acces lattice shouldn't be like this, I'm working on a windows machine, so I dont know if that results in any inconsistencies.

Problem "boarder condition" for "find.neighbours"

There is an error with the "find.neighbours" function. Whenever it is finding neighbours at the edge of a lattice, it jumps to the other side and finds a neighbour there. Can you resolve this so it only finds neighbours at the right edge?
