GLU port for OpenGL ES

SDL Development
1

Hello, All!

If someone looks for GLU port for OpenGL ES, look at my partial port,
located at http://glues.googlecode.com . It has quadrics and 2D mipmaps
also. Right now it supports QNX build target only, but could be easily
ported to any platform, which supports OpenGL ES.

P.S. This port already supports SDL 1.3, I’ll add SDL-based GLU tests for
OpenGL ES soon.

With best regards, Mike Gorchak. E-mail: @Mike_Gorchak

Hi Mike, that sounds interesting, are there any plans to add gles 2.0
support? not meaning to throw more work at you :slight_smile: I certainly would be
interested in seeing this running on my beagleboard> ----- Original Message -----

Since I do not have any GLES 2.0 implementation (on my QNX box or on my WM6
mobile), it is not possible to test GLU ES under GLES 2.0. But I’m
interested in it :slight_smile: Maybe you know some software GLES 2.0 implementation
which could just render all stuff to offscreen buffer ?

Mesa3D renders very well to a offscreen buffer … and it is easy to port to QNX6.

Mesa 3D has GL ES support ?

P.S. Armin, regarding your old request about OpenGL ES support in SDL under
QNX, I’m afraid it is not possible to port all stuff correctly to QNX right
now, take a look at all bugs in QNX/GF/GLES, which I’ve found during one
month of development:

http://community.qnx.com/sf/go/projects.graphics/discussion.opengl_es.
http://community.qnx.com/sf/discussion/do/listTopics/projects.graphics/discussion.advanced_graphics
http://community.qnx.com/sf/discussion/do/listTopics/projects.graphics/discussion.photon_microgui

And looks like they will not fix them until 6.4.2 release, it could took one
year +/- few month …

Hi Mike me again,

just took a look into Mesa as suggested by Armin and a project that is
linked off the site for GLES1.x is the Vincent library, looking further into
that i found
http://sourceforge.net/projects/ogles2 which is the Vincent ES 2.x
implementation, no actual packages however the subversion source is there,
it was a cursory glance on my part, I have no experience of QNX so i don’t
know how useful this will be to you, but I hope it can be of some help.

No, but GL ES is a functional subset of OpenGL … even if the coding is different.
Whay not using Mesa3D (~OpenGL) ??

So … do you think that the advanced graphic packageisn’t a base for a port of SDL 1.3 ?

Really Mesa3D will have support for OpenGL ES, I’ve seen some work in this
direction. OpenGL ES 2.0 has no compatibility with OpenGL ES 1.1, like
OpenGL 2.0 has compatibility with OpenGL 1.5. OpenGL ES 2.0 do not supports
matrix operations, stack of matrices, client states, etc, while OpenGL 2.0
has all of these functions. So all my code must be totally rewritten.

Definitely not for QNX 6.4.0, maybe 6.4.1 will have all neccessary fixes.
