Fields⤴
These are the X3D / X3DOM fields of this node. Values should usually be received / set as strings via
DOM functions (i.e., using
setAttribute("myFieldName", "myFieldValue") and
getAttribute("myFieldName")).
| Name | Type | Default Value | Range | Inheritance | Standard | Description |
|---|---|---|---|---|---|---|
| ambientIntensity | SFFloat | 0 | [0, 1] | X3DLightNode |
|
The ambientIntensity specifies the intensity of the ambient emission from the light. Light intensity may range from 0.0 (no light emission) to 1.0 (full intensity). |
| attenuation | SFVec3f | 1,0,0 |
|
PointLight node's illumination falls off with distance as specified by three attenuation coefficients. The attenuation factor is: 1/max(attenuation[0] + attenuation[1] × r + attenuation[2] × r^2, 1) where r is the distance from the light to the surface being illuminated. The default is no attenuation. An attenuation value of (0, 0, 0) is identical to (1, 0, 0). Attenuation values shall be greater than or equal to zero. | ||
| color | SFColor | 1,1,1 | [0, 1] | X3DLightNode |
|
The color field specifies the spectral colour properties of both the direct and ambient light emission as an RGB value. |
| global | SFBool | false | X3DLightNode |
|
Specifies whether the light is global or scoped. Global lights illuminate all objects that fall within their volume of lighting influence. Scoped lights only illuminate objects that are in the same transformation hierarchy as the light; i.e., only the children and descendants of its enclosing parent group are illuminated. | |
| intensity | SFFloat | 1 | [0, 1] | X3DLightNode |
|
The intensity field specifies the brightness of the direct emission from the light. Light intensity may range from 0.0 (no light emission) to 1.0 (full intensity). |
| location | SFVec3f | 0,0,0 |
|
The position of the Light | ||
| metadata | SFNode | X3DMetadataObject | Core/X3DNode |
|
Field to add metadata information | |
| on | SFBool | true | X3DLightNode |
|
The on field specifies whether the light is enabled or disabled. | |
| radius | SFFloat | 100 |
|
A PointLight node illuminates geometry within radius length base units of its location. Radius is affected by ancestors' transformations. | ||
| shadowFilterSize | SFInt32 | 0 | X3DLightNode |
|
Sets the smoothness of the shadow umbra. | |
| shadowIntensity | SFFloat | 0 | [o, 1] | X3DLightNode |
|
Defines the attenuation of the shadows |
| shadowMapSize | SFInt32 | 1024 | [0, inf] | X3DLightNode |
|
Specifies the resolution of the used shadow map. |
| shadowOffset | SFFloat | 0 | X3DLightNode |
|
Defines the shadow offset for the back projection of the shadow map. | |
| zFar | SFFloat | -1 | -1 or [0, inf] | X3DLightNode |
|
Specifies the placement of the far plane of the light projection. Objects that are farther away from the light source than the far plane do not cast shadows. If the zFar value is not set, the far plane is placed automatically. |
| zNear | SFFloat | -1 | -1 or [0, inf] | X3DLightNode |
|
Specifies the placement of the near plane of the light projection. Objects that are closer to the light source than the near plane do not cast shadows. If the zNear value is not set, the near plane is placed automatically. |
