As Sean mentioned in brlcad-devel Digest, Vol 607, Issue 1

  • Downloaded the current version of the BRL-CAD code and build it
  • Studied the libdm library

Week 23/05/2015 to 30/05/2015

  • Start coding StepViewer
  • First task (as Sean has mentioned) Try to create a libdm window
  • Creation of the libdm window of type X and OGL failed.
