Visualization of the SDR for higher level functionality debug #7

Closed alior101 closed 5 years ago

alior101 commented 5 years ago

We need some kind of visualization to understand what's going on inside the model. This is especially true for grid cells setups... Any easy to integrate c++ graphics lib like in htm path ?

I think we need something like matplotlib but supports realtime ploting. There's look like barely anything in C++.

Well... I use imgui + SFML with a very hacky SDR display function in HTMPath. It is not ideal for a reusable code.

I find myself using ROOT a lot to build, experiment and plot new layers. But ROOT is a very heavy dependency.. ArrayFire's graphics module is also easy to integrate. But again ArrayFire is a very heavy dependency.

After some googling, matplotlib-cpp seems to be a good solution but we'll have to link to Python. PLplot looks like a good solution but I'm not familiar with it.

On a related note. We could build a Python wrapper and do experiments in the python world. A Python wrapper is on the roadmap so we'll build one someday. But I think it is way too much work for now.

What do you think?

Let me look at the options ... I like matplotlib-cpp need to play with it a little to see how it plots in real time .. I'll you know once I have something to show

I guess this have been solved since #39 have been merged? Closing. Feel free to reopen.
