Thank you Antoine, this error can be fixed, when you replace all CRLF by
CR in the shader files (eg. with Notepad++).
Does someone else know the error message, when loading shader files??

hi,
I confirm that the example "01.simple_texture.pd" doesn't work for me
on Windows 7 with pd-extended 0.44-0 and Gem 0.93.3
And none of the 10.glsl/ example work.
All send the same errors:
[glsl_vertex]: error reading file
[glsl_fragment]: error reading file

Thanks again for your help!!
What I did:
- I downloaded and installed Pd-extended for Windows from
here: http://puredata.info/downloads/pd-extended (v0.43.4,
Windows Installer)
- I started pd with "pd-extended.bat" in pd folder
- When I'm running pd all GEM details are displayed
(version,...) -> I guess GEM is loaded properly
- I opened example patch 01.simple_texture.pd in folder
\extra\Gem\examples\10.glsl
- I can load the images but when I want to load the shader
these error messages are displayed:
[glsl_vertex]: error reading file
[glsl_fragment]: error reading file
- after replacing all CRLF by CR I receive different error
messages, as I described below!?
I could load neither .vert nor .frag files! I will send them
to you in a seperate email.
The files are existing and found by pd, otherwise I would
receive a different error message....

Dear list,
I tried to get familiar with shaders in GEM. I started
with "01.simple_texture.pd" in folder 10.glsl.
I can start rendering (checking "rendering") but I
cannot load shaders. After checking the rendering
checkbox 2 errors occur:
[glsl_vertex]: need to load a shader
[glsl_fragment]: need to load a shader
When I try to use shaders (click on "load shader") I
receive the error message:
linking: link 1.5 3.5
[glsl_program]: Info_log:
[glsl_program]: Vertex info
-----------
(0) : error C5145: must write to gl_Position
[glsl_program]: Link failed!
These errors occur when I either try to open a ".vert"
or a ".fraq" file! Do you have any ideas what I could
try to use different shaders??? Below I'm listing my
system details:
are you really sure you did not modifies oher things in
the shader code?
if so, could you send them to me so that i can check.
c
- pd: 0.43.4-extended
- GEM: 0.93.3
- System: Windows 7-64
- Folder contains no spaces:
"C:\pd-0.43.4\extra\Gem\examples\10.glsl"
- I replaced all CRLFs with CRs as I found in
https://sourceforge.net/p/pure-data/bugs/864/?page=2
(otherwise I get the errors
[glsl_vertex]: error reading file
[glsl_fragment]: error reading file
- I also tried to run pd with Admin permissions
Thanks in advance!!
Br, Michael

Hello,
Yep, and if oculus doesn't provide a shader for
barrel distortion, there
is plenty of example on the web.

hello,
one have to use shader in order create the
image distortion.
i think oculus should provide standard shader
that you have to insert
in your rendering process.
the only problem is that you have to do 2
rendering : one for each eye.
The best solution is to do a 3 pass rendering :
1st : left eye view without distortion,
rendered in a frame buffer
2nd : right eye view (no distortion / framebuffer)
3rd : using the 2 previous texture and a
shader, render the final image

Dear list,
we are using GEM with a
head-mounted-display to present a virtual
world to subjects performing acoustic
localization experiments.
Now we plan to switch from our current HMD
to Oculus Rift (an
upcoming virtual reality head-mounted
display). Therefore we need to
modify our image and add (asymetric)
barrel distortion to the
represented image. (The image distortion
is compensated by the lenses
in Oculus Rift.)
My questions now:
- Is there an easy solution to implement
barrel distortion to the
rendered window in GEM?
- Does anybody of you already have some
experience with GEM together
with Oculus Rift?
Since attachments should be avoided in
this list, I do not send any
example pictures of the distortion or our
current presented world. If
you are interested you can either contact
me and I can send you some
screenshots, or you can google for example
images/videos of Oculus
Rift distortion.
Thanks in advance and best regards, Michael
