Περίληψη:
One of the most promising techniques for visualizing three-dimensional
objects is Integral Photography (IP). Two of the most common methods
used in Computer Generated IP involve the development of simplified ray
tracing algorithms for elementary 3D objects or the realization of
pinhole arrays. We present an alternative technique based on the POV-Ray
software package for ray tracing to generate synthetic, high quality and
photorealistic integral images, by accurately modeling all the optical
elements of the capturing setup. Our work constitutes a straightforward
approach for translating a computer generated 3D model to an IP image
and a robust method to develop modules that can be easily integrated in
existing ray-tracers. The proposed technique simulates the procedure of
a single stage IP capture for producing orthoscopic IP images, real or
virtual. Full control is provided over geometry selection, size and
refractive index of the elementary microlenses. Specifically our efforts
have been focused on the development of arrays with different geometries
(square or hexagonal) that demonstrates the parameterization
capabilities of the proposed IP setup. Moreover detailed benchmarking is
provided over a variety of sizes and geometries of microlens arrays.
