Open Task
Task Name Hardware accelerated blitting
Technical Contact(s) Einar Johan Trøan Sømåen, Johannes Schickel, Alyssa Milburn
Subsystem Engine


Some engines (Wintermute, Broken Sword 2.5) would greatly benefit from having the option of hardware acceleration for their graphics code, for fast alpha (transparency) blitting, rotation, scaling, etc.

The Task:

  • Plan, discuss and develop a design for a generic API for hardware acceleration.
  • Implement the API for several backends (for example the desktop OpenGL backend, and OpenGL ES backends such as iOS and Android), updating/refactoring the backend code as necessary to keep the code stable and maintainable.
  • Update the Broken Sword 2.5 engine code to use the new API.
  • Update the Wintermute engine code to use the new API.

Required Skills:

  • Good C++ skills.
  • Good knowledge of ScummVM coding conventions and portability guidelines (could be learned in less than a week)

Helpful to Have:

  • Some basic knowledge of OpenGL and OpenGL ES.
  • Access to several different supported platforms for testing.
