WebTo this ends, OpenGL has built-in functions for applying several standard transformations (translation, rotation, and scalings) along with a general one for applying any user-defined matrix. By concatenating transformations together, i.e. applying several transformations at the same time, additional effects can be achieved. WebTransformation function. (Optional) Specifies the continuous function to transform the values from the input raster. The transformation functions are used to specify the function to rescale the input data. A general description of each function and the default values for the functions are detailed in the table below.
