DESCRIPTION
I spent some time on prototyping area lighting in MagicaCSG this weekend (though I need to finish bug fixes for the last beta version, which will be released by the end of this month).
This new feature allows you to add and transform multiple rectangle light sources in the scene (similar to the background images).
You can use area lighting to cast nice hard or soft shadows (depending on the size):
The luminance depends on the angle and distance between the surface and light sources. It works with all types of built-in materials, but adds extra cost for rendering, which may be expensive for complex scenes.
Of course, we can have more types and properties for light sources, but let's add the preliminary support first.
