Mandelbrot Explorer Using Pixel Shaders

Okay, I futzed around with it and now it's running on my iPhone 5s. The .love file in the original post is updated, as well as the code on Github.

Let me know if it doesn't work anywhere else and I'll take a look. For what it's worth, there's not many features on mobile, since you can't use the keyboard and right-clicking doesn't work, so, it's just more of a novelty.

Very cool!



Seems to break down after a while, but it is quite pretty nonetheless!

I think this is due to the colormap vec3 array I'm passing into the shader, different graphics hardware have different size limitations on extern variables. Try changing the 'colors' extern in the 'shader.frag' file to have a size of 200 or something, I don't think the colormap file ever tries to pass in a colormap with more than 200 colors.

Very cool!

Thanks for the positivity Karai The negativity around here was getting me down a little.

And you're right, it breaks down due to the finite accuracy of the floating point number type in GLSL. You could get around it by implementing an arbitrary precision number type, but I'm not sure if it would run in real-time anymore without serious mathy optimization that's outside of my experience.

Time to get experience!
