Current commercial Virtual Reality (VR) headsets give viewers immersion in virtual space with stereoscopic graphics and positional tracking. Developers can create VR applications in a working pipeline similar to creating 3D games using game engines. However, the characteristics of VR headsets give disadvantages to the rendering technique particle system with billboard sprites. In our study, we propose a rendering technique called FOggy-LAser Rendering method (FOLAR), which renders realistic laser in fog on billboard sprites. With this method, we can compensate for the disadvantages of using particle systems and still render the graphics in interactive performance for VR. We studied the characteristics of this method by performance benchmarks and comparing the rendered result to a baseline ray-casting method. User study and image similarity metrics are involved in the comparison study. As a result, we observed a satisfying performance and a similar rendering result compared to ray-casting. However, the user study still shows a significant difference in the rendered result between methods. These results imply that FOLAR is an acceptable method for its performance and ness in the rendered result, but still have inevitable trade-offs‌‌‌ in the graphics. ; Nuvarande kommersiella Virtual Reality (VR) headset ger användare immersion i virtuellt utrymme med stereoskopisk grafik och positionsspårning. Utvecklare kan skapa VR-applikationer i en fungerande pipeline på ett liknande sätt som att skapa 3D-spel med hjälp av spelmotorer. Egenskaperna hos VR-headset ger emellertid nackdelar med renderingstekniken av billboard sprite partikelsystem. I vår studie föreslår vi en renderingsteknik som kallas FOggy-LAser Rendering method (FOLAR), som renderar realistiska lasrar i dimma på billboard sprites. Med denna metod kan vi kompensera för nackdelarna med att använda partikelsystem och fortfarande göra grafiken i interaktiv prestanda för VR. Vi studerade egenskaperna hos denna metod genom prestanda benchmarks och jämförde ...
