open in visual studio. Compile all. Fine.
GDiviaAGGTest works fine
But all TestBench fails at this stage
=> throw new Exception

GL Error: InvalidValue

What OS/hardware is this on?

[JimSEOW]

windows 8.1 on laptop which is less than 1 year old.
I doubt hardware issues as I regularly compile and run many different OpenTK or SharpGL projects

It would be great to be able to just download and unzip the file, compile and run to see how the demo look without further debugging.

[jeske]

It's not hardware issues..it is hardware compatibility issues with our shaders. GLSL compilers are drastically different in different drivers. We develop on nvidia, which is very "forgiving" of mistakes. Intel and AMD are less forgiving. Bottom line.. We need to know what hardware you are running to debug our shaders.

[JimSEOW]

Nvidia GeForce GTX 780M
I was looking for ideas on how to implement scence graph. This project is suitable for this purpose. Good JOb

I tested
https://github.com/Namone/SimpleScene

I removed this line

        //checkErrors();

in SSMainShaderProgram.cs

The WavefrontOBJViewer program works!!!

SSShaderProgram.cs
protected void checkErrors() {
ErrorCode glerr;
if ((glerr = GL.GetError ()) != ErrorCode.NoError) {
throw new Exception (String.Format ("GL Error: {0}", glerr));
}
}

[jeske]

My NVidia drivers don't throw those shader errors. Does your laptop have dual-graphics? Those errors look more like the kind of things I see out of intel drivers (which are less forgiving)

Namone/SimpleScene is just an old version before we added lots of other features.

You can try to make our latest tree work by forcing the geometry shader off... In SSMainShaderProgram.cs, SSMainShaderProgram, change this line:

if (GL.GetString(StringName.Extensions).ToLower().Contains("gl_ext_gpu_shader4")) {

to this:

if (false && GL.GetString(StringName.Extensions).ToLower().Contains("gl_ext_gpu_shader4")) {

... We should change this code so if the SS4 shader compile fails it just falls back to the SS1 shader automatically.

[jeske]

Can you try the latest ( https://github.com/jeske/SimpleScene ) ?

I put some code into the shader load to automatically fall back to the simpler SS1 shader if the SS4 shader load fails. I'd like to know if this fixes your startup problem.

NOTE: this isn't really the best "fix" because we also want the SS4 shader to load on your hardware, but I need to get access to a setup that causes the problem to fix this.

[JimSEOW]

Does your laptop have dual-graphics?
YES. it switches between intel ( Intel HD Graphics 4000 + ) and Nvidia.

Perhaps this could be the common issue. Perhaps you could notify new user to take this into consideration when running this stimulating project

[jeske]

Dave - can you try the latest version and let us know if it works?

[JimSEOW]

I still think it is important that people know https://github.com/Namone/SimpleScene (a version for beginner to immediately test OpenTK scene graph).
