Light
Methods: aspose.threed.entities (aspose-3d-foss)
Light is een Entity die een lichtbron toevoegt aan een 3D‑scène. Zoals Camera, is het gekoppeld aan een Node om de positie en richting te regelen.
class Light(Camera):Methods
A3DObject → SceneObject → Entity → Camera → Light
Light erft van Camera. Light klasse zelf stelt geen extra eigenschappen beschikbaar, behalve die geërfd van Camera en Entity. LightType enum bestaat voor het categoriseren van lichten, maar er is geen light_type eigenschap op de Light klasse.

Methods
| Signature | Description |
|---|---|
__init__(name: str, light_type) | |
move_forward(distance: float) | |
get_bounding_box() | Returns the bounding box. |
get_entity_renderer_key() | Not implemented in the FOSS edition — throws at runtime. Returns the entity renderer key. |
remove_property(property) | |
get_property(property: str) | |
set_property(property: str, value) | Sets the property value. |
find_property(property: str) |
Light erft ook alles Camera eigenschappen (near_plane, far_plane, enz.), hoewel deze niet betekenisvol zijn voor lichte objecten. Opmerking: de Light class exposeert geen light_type eigenschap in het huidige API-oppervlak.
LightType-waarden
from aspose.threed.entities import LightType| Methods | Methods | Methods |
|---|---|---|
LightType.POINT | "POINT" | Zendt licht gelijkmatig in alle richtingen uit vanuit één punt. |
LightType.DIRECTIONAL | "DIRECTIONAL" | Parallelle stralen van een oneindig verre bron (zoals zonlicht). |
LightType.SPOT | "SPOT" | Kegelvormige straal; positie en richting zijn van belang. |
LightType.AREA | "AREA" | Licht uitgezonden vanuit een rechthoekig gebied. |
LightType.VOLUME | "VOLUME" | Volumetrisch/global illumination-licht. |
