blenderproc.python.loader.Pix3DLoader module

class blenderproc.python.loader.Pix3DLoader.Pix3DLoader

Bases: object

This loads an object from Pix3D based on the given category of objects to use.

From these objects one is randomly sampled and loaded.

Note: if this class is used with another loader that loads objects with semantic mapping, make sure the other module is loaded first. TODO: Really?

static _correct_materials(objects)

If the used material contains an alpha texture, the alpha texture has to be flipped to be correct

Parameters:objects (List[MeshObject]) – The list of mesh objects where the material maybe wrong.

static get_files_with_category(used_category, data_path)

Returns a list of a .obj file for the given category. This function creates a category path file for each used category. This will speed up the usage the next time the category is used.

Parameters:

• used_category (str) – the category something like: ‘bed’, see the data_path folder for categories
• data_path (str) – path to the Pix3D folder

Return type:

list

Returns:

list of .obj files, which are in the data_path folder, based on the given category

blenderproc.python.loader.Pix3DLoader.load_pix3d(used_category, data_path='resources/pix3d')

Loads one random Pix3D object from the given category.

Parameters:

• used_category (str) – The category to use for example: ‘bed’, check the data_path/model folder for more categories. Available: [‘bed’, ‘bookcase’, ‘chair’, ‘desk’, ‘misc’, ‘sofa’, ‘table’, ‘tool’, ‘wardrobe’]
• data_path (str) – The path to the Pix3D folder.

Return type:

List[MeshObject]
