In order to solve the problem, triangle vertices order is inverted in mirrored mesh (triangulation). Mesh considered to be mirrored if its transformation matrix determinant is less than 0. To handle AIS object mirror transformations "Mirrored" flag stored in OpenGl_Structure. If this flag is enabled, glFrontFace (GL_CW) applied before the draw call. New DRAW commands for visualization level transformations added.
