(In Danish) LEGO Digital Designer er et frit tilgængeligt program til at bygge LEGO-modeller i 3D på en almindelig computer. Konsulentaftalen med Alexandra Instituttet har løbet siden december 2009, og vi har i den forløbne tid implementeret en række teknikker der giver en afgørende bedre realisme i den interaktive grafiske fremstilling af LEGO-klodser. Avancerede visuelle effekter Det drejer sig om visuelle effekter som bløde skygger, refleksioner og farveblødning. Disse visuelle fænomener er vigtige for en god forståelse af form, materiale…
This is some of our latest coding, we have been trying to implement a cool technique called Light propagation volumes, that essentially can calculate diffuse and glossy light reflections. and thereby add some global illumination in form of indirect light to your rendering. The technique is described in these papers: Light_Propagation_Volumes.pdf and the recent paper : http://www.vis.uni-stuttgart.de/~dachsbcn/download/lpv.pdf In the video we experiment with glossy reflections by using ray marching in the reflected direction as described in the papers.
We just updated our smoke and density field viewing software, so it runs a lot faster and we are at this moment experimenting with realtime indirect photontracing and gpu kd construction. Life is good 🙂
