Objectives Completed#

  • ComboBox2D UI Component

    A combobox is a commonly used graphical user interface widget. Traditionally, it is a combination of a drop-down list or list box and a single-line textbox, allowing the user to select a value from the list. The term “combo box” is sometimes used to mean “drop-down list”. Respective components, tests and tutorials were created.

    Pull Requests:

  • Tab UI Component

    In interface design, a tabbed document interface or Tab is a graphical control element that allows multiple documents or panels to be contained within a single window, using tabs as a navigational widget for switching between sets of documents. Respective components, tests and tutorials were created.

    Pull Requests:

  • Double Click Callback

    Double click callbacks aren’t implemented in VTK by default so they need to be implemented manually. With my mentor’s help I was able to implement double click callbacks for all the three mouse buttons successfully.

    Pull Requests:

  • TextBlock2D Improvements

    The previous implementation of TextBlock2D was lacking a few features such as size arguments and text overflow. There was no specific way to create Texts occupying a said height or width area. Apart from that UI components like ListBoxItem2D, FileMenu2D etc had an issue where text would overflow from their specified width. In order to tackle these problems, a modification was done to TextBlock2D to accept size as an argument and a new method was added to clip overflowing text based on a specified width and to replace the overflowing characters with ....

    Pull Requests:

  • Physics Engine Integration

    Optional support for Physics engine integration of Pybullet was added to Fury. Pybullet’s engine was used for the simulations and FURY was used for rendering the said simulations. Exhaustive examples were added to demonstrate various types of physics simulations possible using pybullet and fury. The said examples are as follows:

    • Brick Wall Simulation

      • Explains how to render and simulate external forces, objects and gravity.

    • Ball Collision Simulation

      • Explains how collisions work and how to detect said collisions.

    • Chain Simulation

      • Explains how to render and simulate joints.

    • Wrecking Ball Simulation

      • A more complicated simulation that combines concepts explained by the other examples.

    Apart from that, a document was created to explain the integration process between pybullet and fury in detail.

Objectives in Progress#

  • Scrollbars as a standalone component

    The previous implementation of scrollbars were hard coded into ListBox2D. Therefore, it was not possible to use scrollbars with any other UI component. Apart from that, scrollbars in terms of design were limited. Creating a horizontal scrollbar was not possible. The objective of this PR is to make scrollbars separate so that other UI elements can also make use of it.

    Currently, the skeletal and design aspects of the scrollbars are implemented but the combination of scrollbars with other UI components are still in progress.

    Pull Requests:

  • File Dialog Improvements

    Currently, we have access to FileMenu2D which allows us to navigate through the filesystem but it does not provide a user friendly Dialog to read and write files in Fury. Hence the idea is to create a file dialog which can easily open or save file at runtime. As of now, Open and Save operations are implemented. Corresponding tests and tutorials are in progress.

Other Objectives#

  • Radio Checkbox Tutorial using FURY API

    The objects for Radio button and Checkbox tutorial were rendered using VTK’s method by a fellow contributor so I decided to replace them with native FURY API. The methods were rewritten keeping the previous commits intact.
