ZCubes Render Examples

ZCubes Render feature allows users to make fascinatingly complex drawings and animations by simply using the spreadsheet, array or table features. To apply render to the last element, use RENDERX function.

Example 1: Two Circles

Draw two circles with radii as given.

RENDER(
   [
      ["type","size"],
      ["circle",100],
      ["circle",200]
   ]
)

Render Two Circles.png

Input data to render can also be given in alternative object formats or vertical formats. Alternative formats

Example 2: Ten Circles

Draw ten circles with radii as per the function given. Note that each ith circle will have the radius as given by the function. Note the use of count column to specify the number of circles to be generated.

RENDER(
   [
      ["type","size","count"],
      ["circle",(i)=>100+i*10,10]
   ]
)
""

Example 3: American Flag

Generating American Flag using RENDER feature. // american flag 4 final

RENDER(
   [
      ["type","x","y",      "width","height","fill",            "count","shape","id","href","sides","size"],

Example 19: Cardioid from Circles

Points around a circle is then used to draw circles with radii that equals the distance between the point and the original first point on the circle.

Refer to [1] (A Cardioid as an Envelope of Lines) [It turns out that we can construct the cardioid as the envelope of curves, and we can do so in a number of different ways. For instance, pick a point P on a circle (the blue circle below, say). Draw circles with centers on the original circle that pass through P. The envelope of these circles is a cardioid.]
