Real-time rendering of textures with feature curves
E. Parilov and D. Zorin
ACM Transactions on Graphics, Vol. 27, No. 1, pp. 1-15 (03/2008)
We present a real-time, GPU-based texture filtering technique which preserves sharp curvilinear features at any resolution. The features can now go along quadratic Bezier curves, with minimal restrictions on their intersections. In our framework, features do not need to be a part of an object boundary - they may be represented by arbitrary functions of the distance and direction to their discontinuity curves. We applied our technique to rendering complex feature patterns and blending normal maps with procedurally defined profiles near normal discontinuities.

Generalized theoretical treatment and numerical method of time-resolved radially-dependent
laser pulses interacting with multi-photon absorbers
E. Parilov and M. Potasek
Journal of the Optical Society of America B, Vol. 23, No. 9, pp. 1894-1910 (09/2006)
We introduce a generalized theoretical treatment and numerical method for characterizing laser interaction with multiphoton absorbing materials as an attempt to unify and to extend all existing methods proposed only for particular materials and against particular lasers. We describe nonlinear materials by using a set of "basic computational blocks", and based on such description we automatically build and numerically solve time-resolved radially dependent coupled rate and propagation equations for input pulse widths varying from ns to fs. We also introduce a new way of computing and analyzing the contribution of each electronic level to the total absorption.

Real-time rendering of normal maps with discontinuities
E. Parilov, I. Rosenberg, and D. Zorin
Pacific Graphics Conference (accepted as a short paper) (08/2005)
We describe a real-time rendering technique which preserves the discontinuity curves of the normal field at sub-pixel level and its GPU implementation. Our representation of the piecewise-continuous normal field is based on approximations of the distance function of the discontinuity set and its gradient. We impose virtually no restrictions on intersections of discontinuity curves, and describe a method for updating the normal field in real-time by blending original field with user-defined surface profile.
