Weekly Check-in #12

Wrecking Ball Simulation, Scrollbars Update, Physics Tutorials.

Hello and welcome to my 12th weekly check-in. In this blog I will be discussing my progress with the wrecking ball simulation and my scrollbar separation work. Apart from this I have also finalized the physics simulation tutorials and have created a Pull Request to finally get it merged with the official repository. The official repository of my sub-org can be found here.

What did you do this week?

This week I was mainly focusing on the wrecking ball simulation. This simulation is basically the combination of chain simulation and brick wall simulation. A sphere attached to a chain smashes a "NxNxN" brick wall. The simulation is as follows:

There's a rendering bug with the cylinders because of which the chain segments look weird. My mentors confirmed that this bug originated from VTK's `cylinder source` method and they are currently working on it to fix it. The simulation will render correctly once that bug is fixed.

Regarding the scrollbar separation task, I was able to fix those callback issues that I was facing. The mouse callbacks on the scrollbar now work correctly:

I have also created a pull request to add the following physics simulations with proper documentation to the main repository:

  • Brick Wall Simulation
  • Ball Collision Simulation
  • Chain Simulation
  • Wrecking Ball Simulation

What is coming up next?

Currently I am a bit confused with the implementation of scrollbars with UI components. I had a meeting with my mentor and he decided to help me out with this. So most probably I will be working with the scrollbar component and its implementation. Next week will also be the final week for GSoC 2020 before the evaluations start so I would work on getting the final documentation and formalities ready.

Did you get stuck anywhere?

Apart from the scrollbar implementation idea, I did not face any major issues.

Thank you for reading, see you next week!!
