I think the "ugly thing" might be because texture is interpolated on triangles (demonstrated after), and a quadrangle is only divided into 2 triangles - up-left and down-right. So to solve the problem, we just need a triangulation network with much higher resolution. One way is to use ParametricPlot: ParametricPlot[ Evaluate[tr@{u, v}], {u, ...

You can use something designed for creating such ilusion :) pic = Import["ExampleData/lena.tif"]; Manipulate[ Graphics3D[{Texture@pic, Polygon[{{0, 0, 0}, {0, 1, 0}, {1, 1, 0}, {1, 0, 0}}, VertexTextureCoordinates -> {{0, 0}, {1, 0}, {1, 1}, {0, 1}}]}, ViewVertical -> {0, 0, 1}, ViewVector -> {{-.2, .5, h}, {100, .5, ...
