[Scummvm-devel] GSoC Student Introduction

[Angus Lees]

Hello Alejandro!

I've just finished rewriting the (unofficial*) Android port to use
OpenGLES1.0.  I'd be delighted to work with you on moving that out into
something reusable across GLES devices (iphone backend currently uses some
simpler GLES code, for example).

There are a number of things that can be done to make it perform better
(GLES1.1 pbuffers and DrawTex).  I'm also looking forward to trying a GLES2
version that uses fragment shaders to reimplement old-skool 8-bit palette
hardware in the GPU ;)
This is also my first real attempt at GL coding, so I'm sure there are
plenty of other things that can be improved.

There are also a few core ScummVM changes that could have a big impact on a
GL(ES) based backend.  In particular:
- Things that read the screen like grabOverlay and lockScreen() are either
slow (copy from graphics memory), or memory intensive (maintain a second
copy in main memory)
- CopyRectToOverlay currently doesn't batch groups of writes at all - which
makes it hard to do a single texture conversion/upload.  This is quite
different to the main game screen with periodic calls to updateScreen().

 - Gus

(unofficial*)  Did my reply to the fingolfin's thread get eaten by list
moderation?  I'll repost.
