Render Stability

This article is obsolete, but kept as a historical record. Do not rely on this information in any way. However, it may be used in the future, so please do not delete or modify.

Objectives

• Intermediate goal: Abstract OpenGL calls so that state can be tracked for the purpose of isolating GL driver bugs
• Ultimate goal: Abstract all OpenGL usage so that SecondLife can be easily ported to another renderer (e.g. DirectX)

Tasks

GL Cleanup

• Reduce the number of places the viewer makes calls to OpenGL so that markers can be set before each call
  • Then, if the viewer crashes even without generating a call stack, the marker value is returned, helping to isolate where the crash occurred

GL Abstraction

• Complete LLVertexBuffer abstraction
• Material abstraction
  • shader and texture setup
• Vertex Buffer Auditing
• Minimize LLGLState Calls
