Abstract:		The paper is dedicated to the development of a vertex shader used to visualize a deformable strip. An approximation of strip geometry in the deformed state is proposed, taking into account the necessity to visualize magnified deformations. Importantly, the deformed state to be zoomed and visualized comes from the solution of elasticity problem considering small deformations. In this case, the zoomed deformed state needs to be defined carefully in order for it to look natural. Also, attention is paid to the approximation of geometry at strip ends, where the deformations are absent. The source code of the vertex shader is listed.
