In this tutorial, the idea is to verify if render software properly simulate colour mixing. For that, we will use, when possible, IES files in order to mimic as much as possible real phenomena. It extends and refreshes the previous tutorial on the same topic: http://www.keris-studio.fr/blog/?p=5475
Colour mixing refers to Grassmann’s laws (https://en.wikipedia.org/wiki/Grassmann%27s_laws_(color_science)). In colorimetry, Grassmann’s laws govern the superposition of colours. They serve as the foundation for all colorimetric calculations. Hermann Grassmann’s 19th-century studies of human colour perception led him to formulate three laws in his 1853 article « On the Theory of Colour Mixing. » (Grassmann, H. (1853). « Zur Theorie der Farbenmischung »). Continue la lecture →
This is workflow to create a scene in Coraulis. It is done in Blender, but can be realised any similar 3D software. The first step consists in creating a “landscape”. We used the Geometry Nodes to create it, but can be done the usual way or with another software equivalently. It is then lit which can also be done anywhere else. Then the camera is animated along a path. The rendering process uses the Equirectangular 360 Camera which is built in Blender. But we can find the same camera in Cinema 4D, 3DsMax or Twinmotion. The 360 film is then recut to fit Coraulis requirements. Step by step with Blender, C4D or Max, we can create an amazing experience with plying with the context, the movements or the light.
