[x3d-public] battle of the composed shaders. X3DOM wins until you teach me how towrite better shaders.

[yottzumm at gmail.com]

Well, with some hints from Doug Sanden’s on another file, I was able to port the shader to the other viewers.

Left over:

BS contact: Probably does not support GLSL (anyone know?)
FreeWRL: where’s the background?   Can I define my own samplercube?

Next, my flowers and my head model.

Thanks,

John

http://coderextreme.net/X3DJSONLD/ball.xhtml  (inlines and URLs, links to shaders)
http://coderextreme.net/X3DJSONLD/ball.x3d (actual file to modify)
http://coderextreme.net/X3DJSONLD/x3dom.vs (working vertex shader in X3DOM)
http://coderextreme.net/X3DJSONLD/common.fs (working fragment shader in X3DOM)

Has a sphere in a scene shown with ComposedShaders.  My challenge for everyone except for X3DOM is to provide better shading programs or shaders to me that will make your viewers look superb like X3DOM.  I suspect that it has something to do with the shaders, but I have only a clue how to write OpenGL ES shaders, and I don’t know how to write portable shaders, it appears.  So I’m hoping you will help.

I have provided links to the X3D and the vertex and fragment shaders.

Also, I’d like to see more support for specifying multiple vendors ComposedShaders or ShaderParts.

FreeWRL:  why can’t I use the same fragment shader as everyone else…you are extremely close!  How do I pass uniform floats to the vertex shader?
Instant Player:  Wow, some strange errors in the console!

Also, it would be nice if I could use the same or similar vertex shader for everyone.  Perhaps look at the vertex shaders and see how to find commonality.

Holger, I know you already replied, but I never saw the shaders you provided.  Could you post them as a reply to this message?  Thanks!

John
