cmiVFX Posted October 21, 2009 Share Posted October 21, 2009 cmiVFX Launches New Subsurface Scattering Video For Houdini Watch High Definition Training Videos For The Visual Effects Industry Instantly From Anywhere In The World. Curitiba, PR, Brazil October 20th, 2009 — cmiVFX | cmiStudios launches a brand new Houdini video for the Subsurface Scattering render option. We have dedicated ourselves to completing training for the most difficult Houdini tasks. Rendering and shading have been to Houdini as Mount St Helens is for mountain climbers. It takes experience to do either one of those things, and we showcase our experience to you here with this fantastic release. This video is available today at the cmiVFX store. cmiVFX Video Player Online Store http://cmivfx.com/store/Browse.aspx?Category=11 Houdini - Introduction to Subsurface Scattering http://cmivfx.com/SideFX_Houdini_Training/intro_to_sss/default.aspx Subsurface scattering (or SSS) is a mechanism of light transport in which light penetrates the surface of a translucent object, is scattered by interacting with the material, and exits the surface at a different point. The light will generally penetrate the surface and be reflected a number of times at irregular angles inside the material, before passing back out of the material at an angle other than the angle it would reflect at had it reflected directly off the surface. Subsurface scattering is important in 3D computer graphics, being necessary for the realistic rendering of materials such as marble, skin, and milk. In Computer Graphics many algorithms simulate SSS. In this video we will review some of the methods that Houdini’s Mantra render engine uses to create SSS effects explaining the theory and applying that to our examples. THE PROJECT Every cmiVFX video is produced with the viewer in mind. We take into consideration the possible questions that will arise from the dissection of in-depth material often disclosed in our content. We do this by creating project data that can be followed in phases. We will start off this video by talking about the basis for which this project will be based. SUBSURFACE SCATTERING Houdini is brings the appearance of magic to the computer desktop. However, in reality, it is comprised of a rich tool set that can be combined with the addition of artistic expression to simulated the look and feel of any natural phenomenon. In this video we talk about Subsurface Scattering, a mathematical notation of how light passes through a solid or fluid body. LIGHTS AND MATERIALS Subsurface Scattering can only exist if a light and solid body are present in nature. The material on a solid body will showcase the length of the rays that get scattered through its center. A common example of this type of scattering is achieved by holding a finger over a bright flashlight in a dark environment. The scattering depicted in this scenario would be from the skin and blood combination within the solid body. We will show you how to get the most out of your materials by creating a orange juice like substance and a plastic substance which will be combined for a final composition. RENDER REFINEMENTS Many artists working with CG will not properly utilized preview rendering. Its always best to control the amount of data used in test rendering by limiting the amount of surfaces seen by rays. When each part works as a whole, then it can be rendered for final tests. We will show you what it takes to get the job done in a timely matter. About the Author: Georges Nakhle is 25 years old, Lebanese, and has a masters degree in mechanical engineering. He began his art steps with traditional painting and sculpting then gained a diploma in dramatic monologue (acting -singing), he has worked as a writer and performer in radio and TV. Combining arts and science led him to CG, so he mastered many tools including Maya and Houdini among others, Georges is also a programmer, so he's currently working for Dassault Systemes in Paris-France. He had also worked in combination with Dassault-Systemes and Mental Images, the makers of mental-ray. About cmiDirect Why "direct"?
