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??

(0) : error C5145: must write to gl_Position
In vertex shader, you need (minimum required) to give a value to the vec4
gl_Position (position of the current vertex).
If you omit to do it you get that error.
the shader Michael is trying do write to gl_Position.
the shader works for me...

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
