Color mixing in computer graphics typically uses simple linear blending in RGB space, with other methods like HSV blending aiming for more intuitive transitions. However, these techniques dont accurately replicate how real-world materials mix pigments.In the 1930s, scientists Paul Kubelka and Franz Munk published a paper called A Contribution to the Optics of Paint Layers. The Kubelka-Munk model offers a physically based approach to color mixing, particularly useful for rendering paints and translucent materials.Jakob Bock, also known as vanity ibex, wrote a blog post discussing implementing the KM model in Houdinis VEX language with practical use cases.This method is especially useful for point-based fluid simulations, with FLIP, POP, or Vellum fluids being the most obvious applications. Although the implementation is simplified, it could be enhanced by introducing real pigment data for more accurate color mixing.Read the article here and support Jakobs work by purchasing the scene files by clicking this link.Visit Jacobs blog for more useful tips and tricks and join our80 Level Talent platform and our new Discord server, follow us onInstagram,Twitter,LinkedIn,Telegram,TikTok, and Threads, where we share breakdowns, the latest news, and awesome artworks.Source link The post Achieve Natural-Looking Color Mixing In Houdini With Kubelka-Munk Algorithm appeared first on CG SHARES.
