 Transform Input Shader and [[Transform Merge Shader]] allow you to transform the output of other shaders by changing their texture coordinates. A transformation can translate (move), scale (resize) and rotate. It can also reset the texture coordinates to a different texture space (e.g. world space or undisplaced space). Any shaders which are upstream (via the main input connection) are affected by the Transform Input Shader, as long as those shaders are programmed to use texture coordinates. Most shaders do use texture coordinates but some exceptions are listed below. The Transform Input Shader works by modifying the texture coordinates before it evaluates the upstream shaders. The upstream shaders see modified texture coordinates and therefore any shapes or textures they produce are transformed in space.
