FOTOSINT: the Ray Tracing approach

The algorithms implemented are:

• Standard ray tracing with or without bounding volume test (bounding volumes are spheres):

  See: Marini D., Tampieri F. - "A Ray Tracing System" - in: Proc. II Colloque Image, Nice (1986)

  See also: Levner G., Marini D., Tassinari P.,"A simple general Method for Ray Tracing Bicubic Surfaces" , in: Earnshow R.A. Ed. Theoretical Foundations of Computer Graphics and CAD, NATO Asi Series, Berlin (1988)

• Fast ray tracing with uniform spatial subdivision:

  See also: Marini D., Rossi M., "Ottimizzazione di Algoritmi di Ray Tracing", (in italian) in: Pixel n. 9, 1990, Ed. Il Rostro, pp. 7-12.

• Parallel ray tracing on Transputers:

  See: Marini D., "An MIMD Architecture for Image Synthesis" (in italian) in: Sistemi informatici e calcolo parallelo, B. Fadini Ed., Franco Angeli, Milano, pp.91-97 (1991)

• Parallel ray tracing on KSR1 shared memory system.

• Progressive ray tracing based on seed filling and progressive refinements.

Living-room (44K) (43K) (44K) (38K). The same model as above computed with a more complex illumination model based on physical properties of matter. Light sources are also defined with classical illuminotechnics parameters: goniometric solid and spectral emission.
