Any idea how to fix this?

Thanks a lot!

I know those modules are from the folder next to the file but for some reason it can't find them :/
I'm also using python 3.7.2 so I had issues with the prints too but I just added some ()

time_rate = (clock.get_time() / 1000.0) / (1 / max_fps)
ZeroDivisionError: float division by zero

I know python 3 would convert the right term to float but
python 3.9 (on win10) is not loading numpy correctly:
RuntimeError: The current Numpy installation ... fails to pass a sanity check due to a bug in the windows runtime. See this issue for more information: https://tinyurl.com/y3dm3h86

Mouse movement is tied to fps and when frames drop it is unusable. Also i move a lot slower when i am close to fractal

Upon running, I receive the following error message:

Compiling Vertex Shader...
Compiling Fragment Shader...
Fragment shader failed to compile with the following errors:

No idea if i'm doing something wrong here, (still relatively new to coding and GitHub), although I haven't altered the file in any way, and have all the required dependencies, but thought i would bring it up anyway.

Whenever i use the install command, my cmd just says it cant find it

I would like to render some of the fractals in more detail (More transformations) how would i do that?

Just a quick question: I noticed there's no way to rotate the camera; I can move my mouse in a circle a bunch of times in order to rotate which direction is up (not sure why this works, but I've seen it happen in some games too,) but there doesn't seem to be a key to do that. I noticed there's a gimbal locked setting in the demo, but no keys bound to rotate. Would this be easy enough to implement?

I'm trying to automate some parameters and I'm having trouble figuring out my issue. I'm getting shader compilation errors when overriding keyvar[3] with with the converted output of my generator. I'm editing the infinite_spheres fractal and trying to automate the first parameter in color:

obj.add(Sphere(0.5, (1.0, 1.0, 1.0), color=('3',0.9,0.5)))

These are the differences in frag_gen.glsl between working and non working:

*****
frag_gen.glsl
        newCol = vec4(vec3(_3,0.9,0.5), de_sphere(p - vec4(vec3(1.0,1.0,1.0), 0), 0.5));
***** 
frag_gen.glsl.broken
        newCol = vec4(vec3(0.9,0.9,0.5), de_sphere(p - vec4(vec3(1.0,1.0,1.0), 0), 0.5));
*****

As you can see the first argument in vec3() is _3 but I'm not sure why. This is how I'm overriding keyvars[3]:

  def rangeMap(x, in_min, in_max, out_min, out_max):
     return (x-in_min) * (out_max-out_min) / (in_max-in_min) + out_min

  sine = float(-1 * math.sin(step) * 2)
  keyvars[3] = rangeMap(sine, -2, 2, 0.2, 0.9)

My first thought was some sort of type error but I've tried removing the float on the sine variable as well as several other type conversions with no luck. Any ideas?

Thanks for the cool fractals!

You have those 6 numbers in keyvars. How do I create a new fractal? I'm on linux, so I'm thinking some of the keybinds might not work, but I can change the values in keyvars. How do I compile a new fractal, without restarting the program? I saw some cool animations in the video, of fractals changing shape, and I wanted to re-create those. I know this isn't an issue, I just don't know how to comment.

Hello Everyone Im Need Help It Very Important Im Needed To Open But It Not Work

The recording functionality (r key) should produce the rendered frames as images, to ./Playback folder.
The problem is that i'm getting totally black images, even changing fps or resolution or any settings inside "camera.py".

Any guess?

This is some really cool stuff, would love to build on it a bit and try to introduce some optimizations for us poor plebs with lower-end hardware. But just how open source is this? Am I allowed to make some small edits and re-release it publicly? Will I get sued if I make my own "marble marcher" style game based on this code and sell it for money?

Hi,
I would like to know how did you come up with NP functions for each shape. Have you found some article on this topic? Please let me know.

Is it possible to render out just a Z-depth map for compositing in software later?
