  • Studied and made modifications to RT^3 Qt project


Bonding Period[edit]

Coding Period[edit]

May 27 - May 31[edit]

  • I am trying to understand how things are happening in BRL-CAD. Things aren't very easily understandable. So I am doing things like breaking and studying the function call stack to understand what happens underneath. I need to do this because I believe I should implement displaying of geometry first since the existing thing in RT^3 project (ray tracing) is not sufficient even for development.
  • Now understand how different DMs display Vlists using OpenGL or Window system methods.
  • I'm studying Vlist creation.

June 1[edit]

  • Vlist obtained for a single solid in RT^3 project

June 2[edit]

  • Added QOpenGLWidget to the application. Line creation is not straight-forward like in the earlier OpenGL version which existing OpenGL DMs use in BRL-CAD. glBegin and glEnd are have been deprecated and now removed in QOpenGLWidget. Studying the new method.
  • Added the deprecated component QGLWidget instead of QOpenGLWidget since the later doesn't support the methods used in BRL-CAD.
  • Studied OpenGL API

June 3[edit]

  • Implemented displaying an object on the QGLWidget using wireframes

June 4[edit]

  • Experimented with some keyboard controls to move around in the scene
