diffuseConstant
The diffuseConstant
attribute represents the kd value in the Phong lighting model. In SVG, this can be any non-negative number.
It's used to determine the final RGB value of a given pixel. The brighter the lighting-color, the smaller this number should be.
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="diffuseLighting1" x="0" y="0" width="100%" height="100%">
<feDiffuseLighting in="SourceGraphic" diffuseConstant="1">
<fePointLight x="60" y="60" z="20" />
</feDiffuseLighting>
</filter>
<filter id="diffuseLighting2" x="0" y="0" width="100%" height="100%">
<feDiffuseLighting in="SourceGraphic" diffuseConstant="2">
<fePointLight x="60" y="60" z="20" />
</feDiffuseLighting>
</filter>
<rect

width="200"
height="200"
