What is PSGL?
• PSGL is the high-level graphics library for PlayStation3
• PSGL is OpenGL ES

• OpenGL ES 1.0
- Officially passed ES 1.0 conformance test
• PLUS programmable shading with Cg
• PLUS OpenGL ES 1.1 extensions
- VBO, FBO, PBO, Cubemap
• PLUS texture extensions
- FP, DXT, 3D, NPO2, Aniso, Depth, Vertex Textures
• PLUS primitive/rendering extensions
- Instancing, Primitive Restart, Queries, Conditional Rendering
• PLUS synchronization extensions
- Fences, Events
• PLUS SCE performance extensions
- TextureReference, AttribSet
• PLUS more

Why use OpenGL ES 1.0?
• PS3 is a graphics powerhouse, needs powerful library
•
•
•
•
•
Embrace an industry standard
Needed a “modern” GL with programmable shaders
Desktop GL has many legacy APIs, not needed for PS3
OpenGL ES at the time was fixed-functionality only
OpenGL ES 2.0 was not ready yet
• Solution: add programmable pipeline to OpenGL ES 1.0

OpenGL ES 2.0?
• OpenGL ES 2.0 is excellent stuff!
• But it came too late in PS3 design cycle
• SCE continues to contribute to Khronos, ES 2.x and beyond
• PSGL 2.0 could be OpenGL ES 2.x-conformant
- Your feedback welcome

Future Directions
• “PSGL”, not “PS3GL”
- Foundation for the future, beyond PS3
• Continue to develop extensions, esp. for performance
-
Higher-level state management
Leverage multi-core and high-bandwidth interconnects
Help good code run faster
Integration of shader effects
• ARB in Khronos
- The best of Desktop and Embedded!
