shader inside a variable ?

[phil1234]

Hello,

 

is there any way to create a shader code(v&f) that comes from an ajax request like stored in a variable ??

Hello,

 

a bit of documentation first: http://blogs.msdn.com/b/eternalcoding/archive/2014/04/17/learning-shaders-create-your-own-shaders-with-babylon-js.aspx

 

To answer your question, just copy your shader to BABYLON.Effect.ShadersStore["MyShaderVertexShader"] and BABYLON.Effect.ShadersStore["MyShaderFragmentShader"]

An example here: http://www.babylonjs-playground.com/#BLA36#4

 

Line 48/49 the shader is defined.

ok thanks

I also noticed by step debugging the engine, that passing shader code in place of <script> tag id should also work, not tested yet

I got a problem with code and coments //

seems like the code is contatenated into a big line, so everything after the ferst // is discared

one solution is to use /* */ but is there no other way ? like injecting \r\n or something ?

 

[edit : solution in php : str_replace("\r\n", "\\r\\n\\\r\n", $text);  ]

Hi Phil,

 

Can you provide an example and paste the code where you're having issues with remarks?  (example "//")  I'm not certain why this would be causing any issues for you.  But if you can post a real example where the script fails, it should be very easy to see what the problem is.

just take any shader(the one in http://www.babylonjs-playground.com/#BLA36#4) and add a comment with //

I mean it's quiet predictable, since if there is no line break, there is noway for the compiler to wknow where comments stops and new line starts

 

to solve this I had to add \n\r inside the string, and voilà

(the shader code is read in php and injected in javascript code)

Hi Phil,

 

I must not understand at all what problems you are running into.  I added dozens of remarks in your playground script, and in pllces where I thought I might have a problem completing a line.  I looked at the shaders, and couldn't break them either.  I saved out a layground scene, however, it's simply a bunch of remarks placed in random lines as well as potentially problematic lines.  But it's so remedial, I won't post unless you ask - but it's really is a worthless example.

 

As I must be misiing the point here, I'll let the dialogue continue, and see what others say concerning your issues.  By the way, the scene is a practicle example of a useful shader for many types of projects and scenes.  It looks great and works well.

 

Cheers,
