core.xqy ("http://mathling.com/art/core")

Some core art support routines used by some of the components.

Randomizer Operations

core:randomize()

core:loop-randomize()

core:loop-select-randomize()

core:random-parameters()

core:random-parameter-map()

core:randomizer()

Parameter Operations

core:parameter()

core:optional-parameter()

Gradients and Effects

core:colours()

core:gradient()

core:effect()

Canvas Operations

core:canvas()

core:scaling()

core:width()

core:height()

core:inner-canvas()

draw.xqy ("http://mathling.com/art/draw")

Drawing code. Unlike svg/draw.xqy, this library draws to domain specific art XML.

Drawing interface

draw:draw()

draw:perspective-draw()

draw:draw-point-matrix()

draw:draw-colour-buckets()

Metadata Creation

draw:dump-randomizers()

draw:dump-parameters()

draw:dump-dynamic-parameters()

components.xqy ("http://mathling.com/art/components")

Component merging part of art execution framework. (See examples/art.xqy.)

Components run off a component definition map. Each entry in the map is keyed by the component name and includes keys for the module namespace (required), which mode of the component to use (default is "default"), and whether to incorporate rendering parameters (default=true()).

Example:

map {
   "example":
     map {
       "namespace": "http://mathling.com/art/example",
       "render": true(),
       "mode": "default"
     }
 }

Components are defined with some well known function names which the component merging framework uses to construct unified bundles of parameters, randomizer descriptors, and so on. If the function is not found, they are presumed to return empty values.

Standard component callback functions

rendering-parameters()

algorithm-mode-parameters()

algorithm-parameters()

randomizers()

colophon()

metadata()
