वच्मि - SVG feSpotLight Filter

Vachmi

The <feSpotLight> filter primitive defines a light source which allows to create a spotlight effect.
It can be used within a lighting filter primitive: <feDiffuseLighting> or <feSpecularLighting>.

Attributes

Attribute

Description

Defines a x-axis coordinate in the user coordinate system.

Defines a y-axis coordinate in the user coordinate system.

Defines a z-axis coordinate in the user coordinate system.

pointsAtX

Represents the x location in the coordinate system established by attribute primitiveUnits on the filter element of the point at which the light source is pointing.

pointsAtY

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.

pointsAtZ

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.

specularExponent

Controls the focus for the light source. The bigger the value the brighter the light.

limitingConeAngle

Represents the angle in degrees between the spot light axis (i.e. the axis between the light source and the point to which it is pointing at) and the spot light cone. So it defines a limiting cone which restricts the region where the light is projected.
No light is projected outside the cone.

Here is the SVG code to draw this filter.
