One of the most promising techniques for visualizing three-dimensional objects is Integral Photography (IP). Two common methods used in synthetic IP generation involve the development of simplified raytracing algorithms for elementary 3D objects or the realization of pinhole arrays. We present a technique utilizing POVRAY’s raytracing capabilities to generate synthetic, high-quality and photorealistic integral images, by accurately modeling an actual microlens array along with the necessary optics. 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 raytracers. The proposed technique simulates the procedure of a single stage IP capture, for producing a real orthoscopic IP image. 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) in order to demonstrate the parameterization capabilities of the proposed IP setup. Moreover detailed benchmarking is provided over a variety of sizes and geometries of microlens arrays.
