GSOC 2025: Meticulous tool polishing and adding new gizmos

[0SlowPoke0]

Hey guys,
My name is Pratyush Harigovind (@0SlowPoke0), and I’ve been selected as a GSoC 2025 student developer to work on Graphite. This summer I will be working on enhancing the Polygon Tool by introducing a wide array of new shapes and designing unique gizmos for intuitive shape manipulation.

Synopsis

Graphite currently has a limited selection of predefined shapes in the Polygon Tool and supports only basic gizmo operations. This project aims to introduce a broader variety of geometric shapes—such as the Trapezoid, Star, Donut, and Pie—each accompanied by its own unique gizmo. These shape-specific gizmos will enable users to create more intricate and expressive vector designs.

To support this, a centralized Gizmo Manager will be developed to manage both generic and shape-specific gizmo behaviors. This includes integration with the Select Tool, allowing seamless shape manipulation and transformation via intuitive visual controls.

Benefits

• A wide selection of new predefined shapes will be available for users.
• Unique gizmos tailored to each shape will allow for more precise and creative editing.
• Enhanced user experience through more interactive and intuitive shape manipulation.

Deliverables

• A centralized Gizmo Manager system to manage and coordinate gizmos associated with shapes created using the Polygon Tool.

• Seamless integration with the Select Tool, allowing users to transform shapes using an intuitive interface.

• Implementation of unique gizmo points for custom shapes including:

  • Polygon, Trapezoid, Triangle, Star, Donut, Pie, Diamond, Segment, Crescent, and more.

• Support for transformation features such as:

  • Editing edge curvature

  • Adjusting segment lengths

  • Modifying radii and angles

  • Moving and refining vertex positions

Week 1

• Unified Shape Tool: Aliased the Line, Ellipse, and Rectangle tools to a new Shape Tool (formerly the Polygon Tool) and added transform cage support, enabling resize, skew, and rotation for created shapes.

Week 2

• Implemented point radius handle gizmo complete with snapping and overlays

test-75.mp4

• Implemented no of point gizmo

73.mp4

• Added an outline overlay for the original shape to visualize what the gizmo are actually affecting

Next week targets

• will be working on implementing above two gizmo for the polygon shape

Week-3

• Implemented point-radius handle and number of point handle for polygon shape, shape outlines for the polygon shape

test-76.mp4

• Added 'Arc' as one of the shapes that can be drawn by the shape tool

test-77.mp4

• Implemented [ / ] keys to decrease/increase the Number of sides when drawing the star or polygon shape

• worked on refactoring the gizmo system and merging the pr

Next-week target

• Add a gizmo to rotate the arcs for the Arc shape

Week 4

• Completed and opened a pull request introducing a new, modular gizmo handler system.
• Implemented arc gizmos

test-79.mp4

• fixed some path-tool bugs
• started working on spiral node

Next week targets -

• Add new spiral types (e.g., logarithmic, Euler, etc.) and integrate them into the Shape Tool.
• Also fix the angle wrapping issue is arc-shape
