  1. 1. Simulated Laser Triangulation with Focus on Subsurface Scattering

    University essay from Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska fakulteten

    Author : Hilma Kihl; Simon Källberg; [2021]
    Keywords : Laser triangulation; subsurface scattering; simulation; speckle pattern; Gaussian beam; Blender; spruce wood; blister package;

    Abstract : Practical laser triangulation sessions were performed for each measurement object to obtain ground truth data. Three methods for laser line simulations were implemented: reshaping the built-in light sources of Blender, creating a texture projector and approximating a Gaussian beam as a light emitting volume.

  3. 2. Estimation of Relative Seismic Velocity Changes Around Katla Volcano, Using Coda in Ambient Seismic Noise

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Frida Jonsdottir; [2018]
    Keywords : Katla volcano; Iceland; ambient seismic noise; coda waves; relative velocity variations; Katla vulkan; Island; omgivande seismiskt brus; codavågor; relativa hastighetsvariationer;

    Abstract : Relative seismic velocity variations in the Earth’s crust can be estimated by using ambient seismic noise records from a pair of stations. Velocity variations can be caused by stress perturbations in the subsurface. Therefore, information on stress changes in the crust can possibly be retrieved from measured velocity variations in the medium. READ MORE

  5. 4. Screen-Space Subsurface Scattering, A Real-time Implementation Using Direct3D 11.1 Rendering API

    University essay from Blekinge Tekniska Högskola/Institutionen för kreativa teknologier

    Author : Dennis Andersen; [2015]
    Keywords : Translucency; Subsurface scattering; Real-time; Compute shader;

    Abstract : Context Subsurface scattering - the effect of light scattering within a material. Lots of materials on earth possess translucent properties. It is therefore an important factor to consider when trying to render realistic images. READ MORE

  6. 5. Efficient Simulation and Rendering of Sub-surface Scattering

    University essay from Medie- och Informationsteknik; Tekniska högskolan

    Author : Apostolia Tsirikoglou; [2013]
    Keywords : subsurface scattering; SSS; translucent materials; BSSRDF; shader; V-Ray; Maya; better dipole; quantized-diffusion;

    Abstract : In this thesis, a new improved V-Ray subsurface scattering shader based on the improved diffusion theory is proposed. The new shader supports the better dipole and the quantized diffusion reflectance model for layered translucent materials. READ MORE
