texture.TextureDescription

moderngl_window.meta.texture.TextureDescription[source]

Describes a texture to load.

Example:

# Loading a 2d texture
TextureDescription(path='textures/wood.png')

# Loading a 2d texture with mimpmaps with anisotropy
TextureDescription(path='textures/wood.png', mipmap=True, anisotropy=16.0)

# Loading texture array containing 10 layers
TextureDescription(path='textures/tiles.png', layers=10, kind='array')

Methods

TextureDescription.__init__(path: str = None, kind: str = None, flip=True, flip_x=False, flip_y=True, mipmap=False, mipmap_levels: Tuple[int, int] = None, anisotropy=1.0, image=None, layers=None, pos_x: str = None, pos_y: str = None, pos_z: str = None, neg_x: str = None, neg_y: str = None, neg_z: str = None, **kwargs)[source]

Describes a texture resource

Parameters:

  • path (str) – path to resource relative to search directories

  • kind (str) – The kind of loader to use

  • flip (boolean) – (use flip_y) Flip the image vertically (top to bottom)

  • flip_x (boolean) – Flip the image horizontally (left to right)

  • flip_y (boolean) – Flip the image vertically (top to bottom)

  • mipmap (bool) – Generate mipmaps. Will generate max possible levels unless mipmap_levels is defined.

  • mipmap_levels (tuple) – (base, max_level) controlling mipmap generation. When defined the mipmap parameter is automatically True.

  • anisotropy (float) – Number of samples for anisotropic filtering

  • image – PIL image for when loading embedded resources

  • layers – (int): Number of layers for texture arrays

  • neg_x (str) – Path to negative x texture in a cube map

  • neg_y (str) – Path to negative y texture in a cube map

  • neg_z (str) – Path to negative z texture in a cube map

  • pos_x (str) – Path to positive x texture in a cube map

  • pop_y (str) – Path to positive y texture in a cube map

  • pos_z (str) – Path to positive z texture in a cube map

  • **kwargs – Any optional/custom attributes

Inherited Attributes

TextureDescription.path

The path to a resource when a single file is specified

Type:

str

TextureDescription.resolved_path

The resolved path by a finder.

The absolute path to the resource can optionally be assigned by a loader class.

Type:

pathlib.Path

TextureDescription.attrs

All keywords arguments passed to the resource

Type:

dict

TextureDescription.label

optional name for the resource

Assigning a label is not mandatory but can help when aliasing resources. Some prefer to preload all needed resources and fetch them later by the label. This can he a lot less chaotic in larger applications.

Type:

str

TextureDescription.kind

default resource kind.

The resource kind is directly matched with the kind in loader classes.

This property also supports assignment and is useful if the kind is detected based in the the attribute values.

description.kind = 'something'
Type:

str

TextureDescription.loader_cls

The loader class for this resource.

This property is assigned to during the loading stage were a loader class is assigned based on the kind.

Type:

Type

TextureDescription.default_kind = '2d'
TextureDescription.resource_type = 'textures'
