pointsAtZ
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
The pointsAtZ attribute represents the z 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
html
<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" filter="url(#lighting1)" />
<rect x="220" y="0" width="200" height="200" filter="url(#lighting2)" />
