pointsAtZ

The pointsAtZ attribute represents the y location in the coordinate system established by attribute primitiveUnits on the <filter> element of the point at which the light source is pointing, assuming that, in the initial local coordinate system, the positive z-axis comes out towards the person viewing the content and assuming that one unit along the z-axis equals one unit in x and y.

You can use this attribute with the following SVG elements:

Example

<svg viewBox="0 0 420 200" xmlns="http://www.w3.org/2000/svg">

  <filter id="lighting1" x="0" y="0" width="100%" height="100%">
    <feDiffuseLighting in="SourceGraphic">
      <feSpotLight x="100" y="100" z="50" pointsAtZ="0" />
    </feDiffuseLighting>
  </filter>
  <filter id="lighting2" x="0" y="0" width="100%" height="100%">
    <feDiffuseLighting in="SourceGraphic">
      <feSpotLight x="100" y="100" z="50" pointsAtZ="80" />
    </feDiffuseLighting>
  </filter>

  <rect x="0" y="0" width="200" height="200" style="filter: url(#lighting1);" />
  <rect x="0" y="0" width="200" height="200" style="filter: url(#lighting2); transform: translateX(220px);" />
</svg>
