Vad är kreativitet - En fenomenologisk studie om en reklambyrås definition och tolkning av begreppet kreativitet (Swedish)
Abstract [en]

With the development of modern GPUs, the computational power they provide have become more accessible and versatile. This has fueled the development of interactive visualization techniques and among them volumetric visualization. The objective of this project is to implement a volumetric path tracer as a reference renderer for volumetric visualization with OpenCL as the target platform. The implementation is created as a processor in an existing visualization framework called Inviwo. The components of the implementation are validated with the help of an analytic single scattering test scenario. The implemented path tracer is then used to render a series of scenes containing both sparse and dense participating media, where the different terms and parameters are studied. The results show comparisons of extinction coefficients, anisotropic scattering using the Henyey-Greenstein phase function, single vs. multiple scattering and a mixed BSDF that is comprised of both a BRDF and an isotropic phase function. One of the conclusions drawn from the results is that multiple scattering not only result in indirect lighting which light up the shadowed regions of the image, but also results in more vivid colors thanks to the sub-surface scattering that naturally occurs.
