4 3D Renderers

4.1 3D Renderer Function Arguments
As with functions that return 2D renderers, functions that return 3D renderers always have these kinds of arguments:
Required (and possibly optional) arguments representing the graph to plot.
Optional keyword arguments for overriding calculated bounds, with the default value #f.
Optional keyword arguments that determine the appearance of the plot.
The optional keyword argument #:label, which specifies the name of the renderer in the legend.
See 2D Renderer Function Arguments for a detailed example.

Returns a renderer that draws points in 3D space.
For example, a scatter plot of points sampled uniformly from the surface of a sphere:
> (define (runif) (- (* 2 (random)) 1)) > (define (rnormish) (+ (runif) (runif) (runif) (runif))) > (define xs0 (build-list 1000 (λ _ (rnormish)))) > (define ys0 (build-list 1000 (λ _ (rnormish)))) > (define zs0 (build-list 1000 (λ _ (rnormish))))
> (define mags (map (λ (x y z) (sqrt (+ (sqr x) (sqr y) (sqr z)))) xs0 ys0 zs0)) > (define xs (map / xs0 mags)) > (define ys (map / ys0 mags)) > (define zs (map / zs0 mags))
> (plot3d (points3d (map vector xs ys zs) #:sym 'dot) #:altitude 25)
When x-jitter, y-jitter, or z-jitter is non-zero, each point p is translated along the matching axis by a random distance no greater than the given value. Jitter may be applied in either the positive or negative direction, so total spread along e.g. the x-axis is twice x-jitter.
Note that adding random noise to data, via jittering or otherwise, is usually a bad idea. See the documentation for points for examples where jittering may be appropriate.

Returns a renderer that plots a function from longitude and latitude to radius.
(f θ ϕ) → r
Currently, longitudes(θ) range from 0 to (* 2 pi), and latitudes(ϕ) from (* -1/2 pi) to (* 1/2 pi). These intervals may become optional arguments to polar3d in the future.
A sphere is the graph of a polar function of constant radius:
Combining polar function renderers allows faking latitudes or longitudes in larger ranges, to get, for example, a seashell plot:
> (parameterize ([plot-decorations? #f] [plot3d-samples 75]) (define (f1 θ ϕ) (+ 1 (/ θ 2 pi) (* 1/8 (sin (* 8 ϕ))))) (define (f2 θ ϕ) (+ 0 (/ θ 2 pi) (* 1/8 (sin (* 8 ϕ))))) (plot3d (list (polar3d f1 #:color "navajowhite" #:line-style 'transparent #:alpha 2/3) (polar3d f2 #:color "navajowhite" #:line-style 'transparent #:alpha 2/3))))

Returns a renderer that plots a single contour line on the surface of a function.
The appearance keyword arguments are interpreted identically to the appearance keyword arguments to isoline.

Use this to visualize functions from three inputs to one output; for example:

Returns a renderer that draws discrete histograms on a two-valued domain.
Missing pairs are not drawn; for example,
> (plot3d (discrete-histogram3d '(#(a a 1) #(a b 2) #(b b 3)) #:label "Missing (b,a)" #:color 4 #:line-color 4))

Returns a renderer that draws a stacked histogram.
Think of it as a version of discrete-histogram that allows multiple values to be specified for each pair of categories.
Examples:
> (define data '(#(a a (1 1 1)) #(a b (1.5 3)) #(b b ()) #(b a (1/2))))
> (plot3d (stacked-histogram3d data #:labels '("Red" #f "Blue") #:alphas '(2/3 1 2/3)))

Returns a renderer that draws a labeled point.
If label is #f, the point is labeled with its position.
Analogous to point-label.
