[sharing] Raymarching in jit.gl.pix

    Dec 22 2013 | 1:33 am
    hello my first test in Raymarching jit.gl.pix. There are problems of small ray. I do not control everything but the tracks are there.
    If someone cycling74 through here, I'd like help on the Param statement in a function.
    In the code box I signal my problem.
    I could achieve this by reading and copying bits of code at:
    I hope to motivate some to do the same :)

    enjoy yourself

      LLT, such good work here, thank you for sharing... did you write this yourself or was it ported from an example? if it's a port, could you share the example to help me understand how this was accomplished? thank you!

      hi, this is a bit of both, I found examples and tips codes at:
      the examples of codes Raymarching was found http://glsl.heroku.com. Unfortunately I do not remember what page of the site exactly.
      I mixed everything and try to understand, there are pieces everywhere :)
      I have to do something else at the moment. But soon I will try to document more code. I've made mistakes in the code, I need to clean. I do not understand everything and we lack examples of cycling74 to help us make the portage.
      Please cycling74 We need a very simple example of Raymarching with pricipale functions.
      I'll be back soon.

      hello everyone I'm a little lost in my previous post for well documented :D
      so this time I chose to do a port of Raymarching http://glsl.heroku.com You will find the source code in the jit.gl.pix.
      I just added the ITER parameter to relieve my little GPU.
      it is difficult for me to run a lot of shader in http://glsl.heroku.com. for example I have trouble figuring out how to mat2, mat3 in jit.gl.pix
      also in the codebox I know declare settings in a function but I can not call it.
      an example:
        oa (q) { param loop (20.)   return cos (qx) + cos (qy * (1.0 + sin (2) * 0.5).) + cos (qz) + cos (qy * loop) * .05; } if I change the parameter in the codebox loop it works but not if I call with a loop variable $1 in jit.gl.pix.
      Team cycling74 here? ;)
