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

Background:

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.
