RayTracer renderer.

Note

We use a environmental sphere wrapped around the scene to render the environment map (i.e. skybox).

Parameters:

• device_index (int, optional) – Device ID used for the raytracer. Defaults to 0.

• logging_level (str, optional) – Logging level. Should be one of “debug”, “info”, “warning”. Defaults to “warning”.

• state_limit (int, optional) – State limit for raytracer integrator. Defaults to 2 ** 25.

• tracing_depth (int, optional) – Tracing depth. Defaults to 32.

• rr_depth (int, optional) – Russian Roulette depth. Defaults to 0.

• rr_threshold (float, optional) – Russian Roulette threshold. Defaults to 0.95.

• env_surface (Optional[Surface], optional) – Environment surface. Defaults to None.

• env_radius (float, optional) – Environment radius. Defaults to 1000.0.

• env_pos (tuple, optional) – Environment position. Defaults to (0.0, 0.0, 0.0).

• env_euler (tuple, optional) – Environment Euler angles. Defaults to (0.0, 0.0, 0.0).

• env_quat (Optional[tuple], optional) – Environment quaternion. Defaults to None.

• lights (list of dict, optional) – List of lights. Each light is a dictionary with keys ‘pos’, ‘color’, ‘intensity’, ‘radius’. Defaults to [{‘pos’ : (0.0, 0.0, 10.0), ‘color’ : (1.0, 1.0, 1.0), ‘intensity’ : 20.0, ‘radius’ : 4.0}].

• normal_diff_clamp (float, optional) – Lower bound for direct face normal vs vertex normal for face normal interpolation. Range is [0, 180]. Defaults to 180.
