Usage

Scroll wheel to zoom, click and drag to pan. Change the initial value of z or c by right clicking.

Custom functions should be valid WGSL expressions, with the following extra functions available:

  • cabs(vec2<f32>) -> f32: absolute value of a complex number
  • cabs_squared(vec2<f32>) -> f32: square of the absolute value of a complex number, (marginally) faster as it avoids a square root
  • csquare(vec2<f32>) -> vec2<f32>: square of a complex number
  • cpow(vec2<f32>, f32) -> vec2<f32>: real power of a complex number (can cause precision issues)
  • cdiv(vec2<f32>, vec2<f32>) -> vec2<f32>: divide two complex numbers
  • cmul(vec2<f32>, vec2<f32>) -> vec2<f32>: multiply two complex numbers

All builtin WGSL functions are also available.
