eradiate.scenes.biosphere.MeshTree#

class eradiate.scenes.biosphere.MeshTree(id='mesh_tree', mesh_tree_elements=_Nothing.NOTHING)[source]#

Bases: eradiate.scenes.biosphere._tree.Tree

A container class for mesh based tree-like objects in canopies.

It holds one or more triangulated meshes and corresponding BSDFs, representing the tree.

The mesh will be interpreted in local coordinates and should be used in an InstancedCanopyElement to place at arbitrary positions in a scene.

Parameters

id (str, optional, default: "mesh_tree") – User-defined object identifier.
mesh_tree_elements (list of (.InstancedCanopyElement | dict), default: []) – List of CanopyElement defining the canopy. Can be initialised with a InstancedCanopyElement, which will be automatically wrapped into a list. Dictionary-based specifications are allowed as well.

Fields

id (str or None) – User-defined object identifier.
mesh_tree_elements (list of InstancedCanopyElement) – List of CanopyElement defining the canopy.

kernel_bsdfs(ctx)[source]#

Return BSDF plugin specifications only.

Parameters: ctx (KernelDictContext) – A context data structure containing parameters relevant for kernel dictionary generation.
Returns: dict – Return a dictionary suitable for merge with a KernelDict containing all the BSDFs attached to the shapes in the canopy.

kernel_dict(ctx)#

Return a dictionary suitable for kernel scene configuration.

Parameters: ctx (KernelDictContext) – A context data structure containing parameters relevant for kernel dictionary generation.
Returns: KernelDict – Kernel dictionary which can be loaded as a Mitsuba object.

kernel_shapes(ctx)[source]#

Return shape plugin specifications only.

Parameters: ctx (KernelDictContext) – A context data structure containing parameters relevant for kernel dictionary generation.
Returns: dict – A dictionary suitable for merge with a KernelDict containing all the shapes in the canopy.
