Image Based Lighting at GTC
One of the surprises for the Iray presentation was to capture an IBL of the GTC keynote stage. This was accomplished by taking a series of photographs and stitching them together to create a spherical image. By mapping this image composite to the inside of a dome, it was used to cast light, reflection, and shadow on the car model. Simply put, the car is 3D CAD data and the background is a composite photograph that simulates the car on stage.
