OpenGL ES 2.0 based #413

Open GoogleCodeExporter opened 9 years ago

In Iphone OS 3.0 you can use OpenGL 2.0.
I do not know the differences between OpenGL ES 1.1 and OpenGL ES 2.0, but I 
think that has better 
performance.

The opengl ES 2.0 is only availble in the 3Gs, and sice cocos2d is a 2d engine I
don't see much advantage in using the 2.0 and leaving lots of older devices 
unsupported.

The advantage to supporting openGL ES 2.0 is that you can do lots of cool 
effects with 
shaders.  True for 2D games too.  For example, the demo Apple shows is a simple 
game 
of pong, but the background is a shader-driven fluid dynamics simulation that 
is 
impacted by the motion of the ball and the paddles.

@nsxdavid
where is this demo?

I think support for ES 1.1 can't be dropped: too much iPod Touch users with 
iPhone OS
2.x out of there.

The docs say the new hardware implements __both__ 1.1 and 2.0.

nGLES_Programming
Guide/OpenGLESPlatforms/OpenGLESPlatforms.html#//apple_ref/doc/uid/TP40008793-CH
106-SW2

Note, on the following page it states you should _not_ restrict to 2.0 only, 
and instead support __both__ if 2.0 
is used:

So this discussion is a non-issue...the guidelines are there to write the code, 
and for all to be happy.  Happy 
New Year. :-)

Sorry, the forum chopped up those URLs.  There is no whitespace between lines.

Hi Riq, any predictions on ES 2.0 shaders?  For mesh-based (non-sprite) game 
elements, they really make a huge difference.

GL ES 2.0 is scheduled after cocos2d 1.0.
Perhaps 4 or 5 months after cocos2d 1.0 is released.

80% of cocos2d is working OK with shaders. See the "gles20" branch:
