Fallback to Mathematica's Rendering

Using MMAView, you can bypass the WLJS pipeline and directly render an expression as it would appear in Wolfram Mathematica.

(1/2 + a)2 // MMAView

Note: The output will be displayed as a raster image, which adds system overhead and results in limited interactivity and non-scalable rendering.

However, MMAView defines special UpValues for 3D graphics, as well as for Manipulate and Animate, making it partially interactive.

With[{p = Plot3D[f[x] y, {x, 0, 10}, {y, 0, 10}]},
  MMAView[p]
]

Manipulate

MMAView can be used as a special wrapper for Manipulate

Manipulate[Plot3D[Sin[n x] Cos[n y], {x,-1,1}, {y,-1,1}], {n, 1, 5, 1}] // MMAView

MMAView is also defined for Animate

Animate[Plot[Sin[x y], {x,0,1}], {y,0,5}] // MMAView
