Re: Mandelbrot Explorer Using Pixel Shaders

I get this error on android. https://love2d.org/imgmirrur/NtKM0oP.png 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 siz...

Re: 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 keyb...

Re: Mandelbrot Explorer Using Pixel Shaders

So, according to the GLSL docs here the log() function is only supported for genType'd arguments, which is floating points (individual numbers, vectors, matrices). So, I guess it was just an implementation detail on my system that an integer argument was accepted. I updated the download in the origi...

Re: Mandelbrot Explorer Using Pixel Shaders

try zooming this 20000x pls Unfortunately not something I think I'll add at this point. This was more of a small experiment, and that requires writing some sort of arbitrary precision floating point implementation, and to keep with the pixel shader usage I'd have to do that inside GLSL. Just tried ...

Hey guys! I first used Love a few years ago when I wanted to try and make some games in high school. I never actually finished anything of note then, and hadn't really looked at Love since. Recently though I'be been trying to get my brother to stop playing so many games and start making some, so the...
