It controls the direction, intensity, and color of the light that affects the appearance of surfaces and shadows in the scene. text/html 2025-05-31T12:37:13+00:00 Anonymous (anonymous@undisclosed.example.com) https://dokuwiki.grogra.de/doku.php?id=01_user_documentation:05_object:02_light:05_sky&rev=1748695033&do=diff Sky The Sky object in GroIMP represents the sky environment and ambient lighting and can be placed into the scene similarily to primitive objects. In the wireframe view, it is displayed as a sphere whose position does not affect the scene because it represents a sky sphere at infinity. text/html 2025-11-01T16:07:21+00:00 Anonymous (anonymous@undisclosed.example.com) https://dokuwiki.grogra.de/doku.php?id=01_user_documentation:05_object:02_light:07_sensors&rev=1762013241&do=diff Sensors Sensors in GroIMP can be used to estimate the power of the rays send by one of the ray tracers without interacting with theses rays. Therefore it allows observation without interference. text/html 2025-07-18T13:48:14+00:00 Anonymous (anonymous@undisclosed.example.com) https://dokuwiki.grogra.de/doku.php?id=01_user_documentation:05_object:02_light:08_channel_maps&rev=1752846494&do=diff Channel maps I would love to know what they are : channel maps text/html 2025-07-18T14:10:50+00:00 Anonymous (anonymous@undisclosed.example.com) https://dokuwiki.grogra.de/doku.php?id=01_user_documentation:05_object:02_light:09_images&rev=1752847850&do=diff Images Every image used within a GroIMP project, e.g., a colouring texture of a 3D material, is shown in the Image Explorer.

The local illumination model is the theoretical framework that describes how incoming light is absorbed, reflected, or transmitted by surfaces at a local point. A shader is the concrete implementation of this model, encoded as an object or class in GroIMP that controls these optical properties for rendering and simulation purposes. text/html 2025-01-30T11:18:13+00:00 Anonymous (anonymous@undisclosed.example.com) https://dokuwiki.grogra.de/doku.php?id=01_user_documentation:05_object:02_light:13_interiors&rev=1738235893&do=diff Interiors Interiors text/html 2025-01-30T11:18:13+00:00 Anonymous (anonymous@undisclosed.example.com) https://dokuwiki.grogra.de/doku.php?id=01_user_documentation:05_object:02_light:15_light_distribution&rev=1738235893&do=diff Light distributions Light distribution text/html 2025-01-30T11:18:13+00:00 Anonymous (anonymous@undisclosed.example.com) https://dokuwiki.grogra.de/doku.php?id=01_user_documentation:05_object:02_light:16_light_spectra&rev=1738235893&do=diff Light spectras Light spectras
