class blenderproc.python.lighting.SuncgLighting.SuncgLighting

Bases: object

static _make_ceiling_emissive(obj, collection_of_mats, ceiling_emission_strength=1.5)

Makes the given ceiling object emissive, s.t. there is always a little bit ambient light.

Parameters:

• obj (MeshObject) – The ceiling object.
• collection_of_mats (Dict[str, Dict[str, Material]]) – A dictionary that contains materials for lamps, windows and ceilings.
• ceiling_emission_strength (float) – The emission strength that should be used for the ceiling. Default: 1.5

static _make_lamp_emissive(obj, light, collection_of_mats, lightbulb_emission_strength=15, lampshade_emission_strength=7)

Adds an emission shader to the object materials which are specified in the light dictionary

Parameters:

• obj (MeshObject) – The blender object.
• light (Tuple[List[str], List[str]]) – A tuple of two lists. The first list specifies all materials which should act as a lightbulb, the second one lists all materials corresponding to lampshades.
• collection_of_mats (Dict[str, Dict[str, Material]]) – A dictionary that contains materials for lamps, windows and ceilings.
• lightbulb_emission_strength (float) – The emission strength that should be used for light bulbs. Default: 15
• lampshade_emission_strength (float) – The emission strength that should be used for lamp shades. Default: 7

static _make_window_emissive(obj, collection_of_mats)

Makes the given window object emissive.

For each material with alpha < 1. Uses a light path node to make it emit light, but at the same time look like a principle material. Otherwise windows would be completely white.

Parameters:

• obj (MeshObject) – A window object.
• collection_of_mats (Dict[str, Dict[str, Material]]) – A dictionary that contains materials for lamps, windows and ceilings.

blenderproc.python.lighting.SuncgLighting.light_suncg_scene(lightbulb_emission_strength=15, lampshade_emission_strength=7, ceiling_emission_strength=1.5)

Makes the lamps, windows and ceilings object emit light.

Parameters:

• lightbulb_emission_strength (float) – The emission strength that should be used for light bulbs. Default: 15
• lampshade_emission_strength (float) – The emission strength that should be used for lamp shades. Default: 7
• ceiling_emission_strength (float) – The emission strength that should be used for the ceiling. Default: 1.5
