Real-time illumination using HDR images

... is the rather long name on a project I did in the course "Image Based Rendering, Lighting and Modelling". Our project used lightprobes, captured with HDR techniques, to shade an object. We used C# and DirectX and shaders written in HLSL, to calculate the lighting from the environment at each point on the object.

We captured the lightprobes ourself in a 24 hour cycle from the roof of one of the student dorms using the different exposure techniques. The images was then assembled in HDR Shop.

In order to use the complete dynamic range found in HDR images we also implemented a "bloom" filter. This filter simulates the lens effect that produces a "halo" around very bright objects which smears out over less bright objects.
