perspective

perspective(
x: angle,y: angle,z: angle,distance: numberauto,sorted: bool,cull-face: nonestr,reset-transform: bool,body: element,
) 

Set-up a perspective projection environment.

Coordinates are transformed by a view matrix and then projected with perspective division: ${𝑥}^{\prime }=\frac{{𝑑}_{\text{ref}}\ast 𝑥}{𝑤}$ and ${𝑦}^{\prime }=\frac{{𝑑}_{\text{ref}}\ast 𝑦}{𝑤}$, where $𝑤=max\left(-𝑧,\text{near}\right)$ in view space.

By default this uses the same isometric camera angles as ortho, but with perspective foreshortening.

perspective({
  on-xz({
    rect((-1,-1), (1,1))
  })
})

x:

angle

X-axis rotation angle

y:

angle

Y-axis rotation angle

z:

angle

Z-axis rotation angle

distance:

number or auto

Distance from camera to scene origin. auto derives a stable value from scene depth.

sorted:

bool

Sort drawables by depth (back to front)

cull-face:

none or str

Enable back-face culling if set to "cw" for clockwise or "ccw" for counter-clockwise. Polygons of the specified order will not get drawn.

reset-transform:

bool

Ignore the current transformation matrix

body:

element

Elements to draw
