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

Dear list,<br>
<br>
I tried to get familiar with shaders in GEM. I started with "01.simple_texture.pd" in folder 10.glsl.<br>
<br>
I can start rendering (checking "rendering") but I cannot load shaders. After checking the rendering checkbox 2 errors occur:<br>
[glsl_vertex]: need to load a shader<br>
[glsl_fragment]: need to load a shader<br>
<br>
When I try to use shaders (click on "load shader") I receive the error message:<br>
linking: link 1.5 3.5<br>
[glsl_program]: Info_log:<br>
[glsl_program]: Vertex info<br>
-----------<br>
(0) : error C5145: must write to gl_Position<br>
[glsl_program]: Link failed!<br>
<br>
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:<br>

are you really sure you did not modifies oher things in the shader code?<br>
if so, could you send them to me so that i can check.<br>

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

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

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