- <h2>Constructor</h2>
- <h3>[name]( [page:Integer color], [page:Float intensity], [page:Number distance], [page:Float decay] )</h3>
- <div>
- [page:Integer color] — Numeric value of the RGB component of the color. <br />
- [page:Float intensity] — Numeric value of the light's strength/intensity. <br />
- [page:Number distance] -- The distance of the light where the intensity is 0. When distance is 0, then the distance is endless. <br />
- [page:Float decay] -- The amount the light dims along the distance of the light.
- </div>
- <div>
- Creates a light at a specific position in the scene. The light shines in all directions (roughly similar to a light bulb.)
- </div>
- <h2>Properties</h2>
- See the base [page:Light Light] class for common properties.
- <h3>[property:Float power]</h3>
- <div>
- Light's power.<br />
- In "physically correct" mode, the luminous power of the light measured in lumens.<br/>
- Default - *4PI*.
- </div>
- <h3>[property:Float distance]</h3>
- <div>
- If non-zero, light will attenuate linearly from maximum intensity at light *position* down to zero at *distance*.<br />
- Default — *0.0*.
- </div>
- <h3>[property:Float decay]</h3>
- <div>
- The amount the light dims along the distance of the light<br />
- In "physically correct" mode, decay = 2 leads to physically realistic light falloff.<br/>
- Default — *1*.
- </div>
- <h3>[property:LightShadow shadow]</h3>
- <div>
- This property stores all relevant information for rendering the shadow of the light.<br />
- </div>
- <h2>Methods</h2>
- See the base [page:Light Light] class for common methods.
- <h3>[method:PointLight copy]( [page:PointLight source] )</h3>
- <div>
- <br />
- Copies value of *source* to this PointLight object.
- </div>
