This goal of this project focused on developing a new image based rendering
technique for constructing a high quality real-time preview of a lighting
environment for a 3d model or scene of arbitrary geometric
and luminary detail.
This particular technique utilizes a view-dependent light field composed of an
array of samples, or rendered images, generated from a fixed
camera position, representing a single, pure light source at a
discrete location in space.
By blending between multiple samples contained within the light
field, an image representing a virtual light source at an
arbitrary position could be reconstructed.
An overview of the design and implementation of a production
oriented prototype application which utilizes the described
technique and achieves real-time performance on an SGI O2
R10k MIPS 512MB workstation running SGI Irix 6.5.x is described in the
corresponding documentation.
