[ dmg . publications . Image Based Rendering: Using High Dynamic Range Photographs to Light Architectural Scenes ] edit
Image Based Rendering (IBR) is a digital rendering technique that uses High Dynamic Range (HDR)
photographs to light three‐dimensional digital models. The HDR photographs capture lighting data
and images from a physical environment: this is done by shooting a range of exposures with a
digital camera and tripod. Once these exposures have been combined into a single HDR
photograph using computer software, the resultant photograph can be inserted into a digital
model, using the IBR method, to act as the light source and background image for the model.
The purpose of this thesis is to explore the IBR method: i) to identify its strengths and weaknesses, ii) to investigate the prescribed method, and iii) to explore its uses as a render and analysis tool for the architectural and lighting design communities. The rationale and methodology are discussed and pertinent information for architectural applications are provided through different settings and lighting conditions.
