Circle Transform Provider Parameters

In this tutorial you will get familiar with CircleTransformProvider's parameters. You will see how change of
parameter values affect transformations provided by CircleTransformProvider.

Agenda:

  • CircleTransformProvider - parameters

Scene setup

Let's use custom scene composer to set up the scene.

    from skyrenderer.cases.utils import TransformProviderSceneComposer
    from skyrenderer.basic_types.provider.transform_providers.circle_transform_provider import CircleTransformProvider
    scene_composer = TransformProviderSceneComposer(antialiasing_level=64)
    scene_composer.setup_scene()
    shaderball_node = scene_composer.renderer_context.layout().get_node("shaderball_GEO")
    shaderball_node.n_instances = 10

CircleTransformProvider - parameters

In this section we will walk you through changing and setting basic CircleTransformProvider parameters:

  • center
  • radius
  • normal vector
  • number of points
    To do that, we will set up separate parameter providers for each combination.

Center

Location of the center of the circle used to draw transformation values.

    renders = {}
    transform_provider_center_000 = CircleTransformProvider(scene_composer.renderer_context, center=[0, 0, 0])
    shaderball_node.modify_locus_definition(transform_provider=transform_provider_center_000)
    renders["center=[0, 0, 0]"] = scene_composer.get_render()
    transform_provider_center_00n1 = CircleTransformProvider(scene_composer.renderer_context, center=[0, 0, -1])
    shaderball_node.modify_locus_definition(transform_provider=transform_provider_center_00n1)
    renders["center=[0, 0, -1]"] = scene_composer.get_render()
    transform_provider_center_01n1 = CircleTransformProvider(scene_composer.renderer_context, center=[0, 1, -1])
    shaderball_node.modify_locus_definition(transform_provider=transform_provider_center_01n1)
    renders["center=[0, 1, -1]"] = scene_composer.get_render()
    scene_composer.visualize_grid_desc(renders, shape=(500, 1500), n_cols=3)
