Generate shaders (10 posts)

    Is there good way to generate shaders on the fly? Essentially I want to convert a string to a shader at runtime. Is it possible in JME?

    <= here we go!
    By meaning of "Generate on the fly", you think about a Node-base Shader Generation System? ..

    P/s: I didn’t test the method out, so don’t know what penalty the result can come across… By the way, I’m doing the same things like in the figure :p if you interest!

    @atomix Almost, but I want to generate shader source at runtime. Having a java program that generates the shader I want =)

    You could make your own loader for that, basically assembling the text for the shader when you are asked for a certain file. (using asset manager)

    @normen ahh, should have thought of that. Can I change the shader for a material at runtime or do I have to load a new material?

    No you have to upload the new shader to the GPU, so basically a new material, yeah.

    But that could be done on runtime, get old amterial, get textures ect, then create new, set the parameters from the old and done.

    @kwando :
    Java program for GLSL shader generation, current NO!

    Java program has “texture” making
    We have NeoTexture(godlike). :p

    ArtOfIllusion have one
    http://aoi.sourceforge.net/scrshots/fullsize/texture.png
    with ability to link directly to a fixed shader!

    For code generation, I recommend a link here (which do it with Velocity)
