Jayson, Sanya, I have read 9937 and I suggest that there is room for a simplified vector class that is suitable for what I would call textbook examples (and more for the right class of problems) where one does not have to worry about transformations from one coordinate system to another, but for t

Sanya, Also only say that you will do the rectangular, cylindrical, and spherical coordinate systems for sure in the allotted time and the rest only if time permits. Do not overcommit yourself. Almost everything in program development takes longer than you think it will even if you are using pyt

Sanya, You need to expand the idea part of your proposal. it should be much more than copying our idea post. You need to explain what you propose to do: what, how, why, etc. It is good to show some example code (pseudo or what you hope the future api will look like). Jason moorepants.info +01 53

Please note the rectangular, cylindrical, and spherical are not the only orthogonal coordinate systems in 3d, see - https://en.wikipedia.org/wiki/Orthogonal_coordinates A unified approach (h_1, h_2, and h_3 functions in link) might be of value. On Tue, Mar 22, 2016 at 12:34 PM, Sanya Khurana wr

2016-03-08 Thread Francesco Bonazzi
Maybe we should change approach to the coordinate systems. Implementing the code inside the *vector* module may end up messing up everything. What about a separate module to handle coordinate system properties in a new-style assumption manner? One could have assumptions like: - Qcoord.is_sp

The link for the scale factors for all 3D separable coordinate systems is - https://en.wikipedia.org/wiki/Orthogonal_coordinates#Table_of_orthogonal_coordinates If you are going to due one you might as well do all of them. On Sat, Mar 5, 2016 at 3:44 PM, Jason Moore wrote: > Here is a pull req

You might want to consider implementing different coordinate systems by defining a metric tensor (g_ij), see link - https://en.wikipedia.org/wiki/Metric_tensor from which all tangent vectors can be derived using the Christoffel symbols - https://en.wikipedia.org/wiki/Christoffel_symbols On Tue,
