ContourHelper clj protocol

ContourHelper provides utilities for computing contour lines using a marching squares algorithm, based on on ContourPy.

See: https://contourpy.readthedocs.io/en/latest/config.html

compute-contour-lines clj

(compute-contour-lines this heightmap threshold)

Given a heightmap, returns the contour lines at the specified threshold as a seq of line segments. If threshold is sequential (vec or seq), then returns a seq of seq of line segments in the same order.

HardwareAcceleration clj protocol

This protocol is implemented to provide hardware acceleration.

info clj

(info this)

Returns information for debugging.

HardwareAccelerationProvider clj protocol

This protocol is implemented to provide access to hardware acceleration algorithms.

create clj

(create this)

(create this opts)

Creates the provider. Opts are a provider-specific map.

name clj

(name this)

Returns the name of the the provider.

NoiseHelper clj protocol

NoiseHelper provides utilities for computing noise functions.

noise2 clj

(noise2 this resolution opts)

Compute 2D noise and return a vec of values. The parameters are as follows: resolution [x y] - the size of the generated noise image in pixels opts { [x y] :scale [x y] :offset } - noise generation options scale [x y] - the scale of the noise, default is [1.0 1.0] offset [x y] - the noise offset, default is [0.0 0.0]

noised2 clj

(noised2 this resolution opts)

Compute 2D noise and and its analytical derrivative, returning a seq. See noise2 for parameter documentation. The resulting seq is packed [value-1 derrivative-x-1 derrivative-y-1 ... value-n derrivative-x-n derrivative-y-n
