eradiate.scenes.integrators.Integrator#

class eradiate.scenes.integrators.Integrator(id='integrator', timeout=None, moment=False, stokes=False, meridian_align=True)[source]#

Abstract base class for all integrator elements.

Parameters:

id (str, optional, default: "integrator") – Identifier of the current scene element.
timeout (float, optional, default: None) – Maximum amount of time to spend during a kernel render pass in second (excluding scene parsing).
moment (bool, optional, default: False) – If true, calculates the variance of the output film
stokes (bool, optional, default: False) – If `True`, calculates and outputs the polarized components ofthe Stokes vector. Note that this will only work with a polarizedmode and a sensor that measures radiance.
meridian_align (bool, optional, default: True) – If `True`, align the Stokes vector to the meridian plane. Otherwisedefault to aligning to the sensor’s x-axis. This parameter is onlyrelevant in polarized mode, when measuring radiance with stokes=True.

Fields:

id (str or None) – Identifier of the current scene element.
timeout (float or None) – Maximum amount of time to spend during a kernel render pass in second (excluding scene parsing).
moment (bool) – If true, calculates the variance of the output film.
stokes (bool) – If `True`, calculates and outputs the polarized components ofthe Stokes vector.
meridian_align (bool) – If `True`, align the Stokes vector to the meridian plane.

Notes

traverse(callback)#

Traverse this scene element and collect kernel dictionary template and parameter update map contributions.

Parameters:: callback (SceneTraversal) – Callback data structure storing the collected data.

update()#: Enforce internal state consistency. This method should be called when fields are modified. It is automatically called as a post-init step.

property objects#

Map of child objects associated with this scene element.

Returns:: dict – A dictionary mapping object names to a corresponding object to be inserted in the Eradiate scene graph.

property params#

Returns:: dict[str, UpdateParameter] or None – A dictionary mapping parameter paths, consisting of dot-separated strings, to a corresponding update protocol.
