Hello, do you mean how to use the touch coordinates in a shader in Shader Editor? Then have a look the pointers uniform (Menu -> Add uniform/texture) and the Touch sample (Menu -> Load sample -> Touch).

Or did you mean how you would set coordinates like this for a shader in OpenGL? Then have a look a the source code.
