Annotations: Implement support for 2D annotations | Project Report

The project was divided into two parts:

  • Creating a new primitive for annotations
  • Rendering the primitives to the wireframe view
  • Support for the screen projection

Creating a new primitive for annotations

  • What was basically required was a container to hold things together
  https://sourceforge.net/p/brlcad/patches/469/#ea23
  https://sourceforge.net/p/brlcad/patches/469/#34f1

Rendering the primitive on screen

  • The next part was to add support for the visualization of the primitive
  • Input for the primitive also handled through the 'in' command in the patches mentioned below
 https://sourceforge.net/p/brlcad/patches/471/#97f3
 https://sourceforge.net/p/brlcad/patches/471/#4b72

Support for the 3D->2D projection

Example annot object created with the in command
  • Annotations always remain in the plane of the screen
  • Modifying the projection matrices for all the display managers was another task
  • Scaling the annotations was another issue
  • All of this was handled by the patches mentioned below
  https://sourceforge.net/p/brlcad/patches/471/#cd2e
  https://sourceforge.net/p/brlcad/patches/471/#acd7

Here is the link to my Proposal The tasks mentioned in the proposal are completed, just the extension ideas need to be worked upon.

Project Extension

  • These are some of the tasks that I aim to work on in the near future:
    • Functionality to set up the annotation properties for the primitive( the annotate command)
    • Features related to the coordinate system like the annotation scaling
    • Algorithm to provide a bounding box for the text using the relative coordinates
    • Editor for the annotations just like the sketch primitive has

Documentation

  • Documentation has been provided here.
