Name

add_scene_3d_lightT_add_scene_3d_lightAddScene3dLightAddScene3dLight — Add a light source to a 3D scene.

Signature

int HScene3D.AddScene3dLight(HTuple lightPosition, string lightKind)

Description

add_scene_3d_lightadd_scene_3d_lightAddScene3dLightAddScene3dLightAddScene3dLight adds a new light source to the scene Scene3DScene3DScene3DScene3Dscene3D and returns its index in LightIndexLightIndexLightIndexLightIndexlightIndex. The kind of the the light source must be specified in LightKindLightKindLightKindLightKindlightKind. For LightKindLightKindLightKindLightKindlightKind = 'point_light'"point_light""point_light""point_light""point_light", LightPositionLightPositionLightPositionLightPositionlightPosition is interpreted as the position of the light source. For LightKindLightKindLightKindLightKindlightKind = 'directional_light'"directional_light""directional_light""directional_light""directional_light", LightPositionLightPositionLightPositionLightPositionlightPosition is interpreted as the vector of the directional light source.

Currently only one light source is supported, such that add_scene_3d_lightadd_scene_3d_lightAddScene3dLightAddScene3dLightAddScene3dLight overwrites the existing light source. This may be changed in future versions.

If no light source is set, a point light source at [-100.0, -100.0, 0.0] is used.
