Hi Aaron ~ Thanks for your quick reply and encouragement. I definitely understand we may be running into a time crunch. And I understand that you want to drive the development of Sympy.
Perhaps we could come up with a small, straightforward project that gets the ball rolling on making Sympy the foundation for a Geogebra style app for building geometric models. My next step for GEOMETOR Explorer is to consolidate the construction logic into a Model class, which could easily become a part of sympy.geometry. The Model can extend from List - so it is just a container of elements. But it would also handle: - deduplicating elements determine if an new element is already in the list. - finding intersections test new elements against previous elements for new points. - maintaining ancestral relationships points contain references to all parent structures. structures contain references to all the points on them. the ancestral trail of an element is its proof. - applying classes to elements like css, associate a list of class names to an element. classes could be used in rendering and analysis. classes could also be used to exclude a structure from testing intersections. - querying subsets provide filtered lists for specific element types or classes In the work I have done so far, I have come to think of elements in 3 categories: - points the data of the model. all points are derived except the given starting points. points are the food for structs. - structs the relationships of the model (lines and circles so far). structs are not a thing in the field, just a projection of a relationship of two points. intersecting structs create points. - graphics the highlights of the model (segments, polygons, wedges). like structs, but are used for highlighting a relationship of 2 or more points and extracting details (length, area, etc). graphics are not tested for intersections by default. I am heading towards subclassing the sympy.geometry elements (Point, Line and Circle) to create attributes for classes and ancestral info that would be managed by the Model. But I can also see a path for maintaining this info outside of the elements in the Model. One of the key considerations I have had from the beginning is to keep the Model separate from the rendering and analysis processes. While I am using Matplotlib today for rendering, I see the opportunity to do really cool things with Blender and FreeCad as well. And for analysis, I have implemented golden section identification so far, but I can see modules for cross ratios, harmonic ranges, etc. Regardless of the decision on the grant, I am committed to developing these concepts. And now that I have opened the door, I hope to share my progress with the community here and hopefully gain insight and knowledge to make the project successful. And I believe that independent work on the Model class could be integrated with Sympy at a later time, once the ideas have matured. The whole concept is pretty straightforward. Thanks again for your attention. ~ φ (phi) On Monday, August 29, 2022 at 12:57:40 PM UTC-7 asme...@gmail.com wrote: > Hi. > > Thanks for sharing.
