Struct julia_set::Params

pub struct Params { /* private fields */ }

Julia set rendering parameters.

The parameters are:

• Image dimensions (in pixels)
• View dimensions and view center determining the rendered area. (Only the view height is specified explicitly; the width is inferred from the height and the image dimension ratio.)
• Infinity distance
• Upper bound on the iteration count

See the Julia set theory for more details regarding these parameters.

Implementations

impl Params

pub fn new(image_dimensions: [u32; 2], view_height: f32) -> Self

Creates a new set of params with the specified image_dimensions and the view_height of the rendered area.

The remaining parameters are set as follows:

• The width of the rendered area is inferred from these params.
• The view is centered at 0.
• The infinity distance is set at 3.

Panics

Panics if any of the following conditions do not hold:

• image_dimensions are positive
• view_height is positive

pub fn with_view_center(self, view_center: [f32; 2]) -> Self

Sets the view center.

pub fn with_infinity_distance(self, inf_distance: f32) -> Self

Sets the infinity distance.

Panics

Panics if the provided distance is not positive.

pub fn with_max_iterations(self, max_iterations: u8) -> Self

Sets the maximum iteration count.

Panics

Panics if max_iterations is zero.

Trait Implementations
