   • Of course, it is impossible to show what a holograph is really like in a two dimensional picture such as this.1983, Ellen Nevins, Encyclopedia of Computers and Electronics, page 108
   • We show that in the two-dimensional case, every objective, isotropic and isochoric energy function which is rank-one convex on #92;mathrm#123;GL#125;#43;(2) is already polyconvex on #92;mathrm#123;GL#125;#43;(2).2015, Robert J. Martin, Ionel-Dumitrel Ghiba, Patrizio Neff, “Rank-one convexity implies polyconvexity for isotropic, objective and isochoric elastic energies in the two-dimensional case”, in (Please...
2. (idiomatic, not comparable, usually) Not creating the illusion of depth; lacking detail or believability.
