Domain coloring is a technique for visualizing functions of a complex variable. You can select one of the preset functions or create/modify your own, rendering is performed combining multi threading so all available cores of CPU are used and a fast zCompiler to achieve near real time display. Results can be exported to a .png or .jpg file in selectable resolution up to 32k width. Formulas can contain: the 'z' variable, operators: +-*/^, parenthesis, complex constants: c(a,b), i.e. c(1,2) is 1+2i, functions: sin, cos, tan, exp, log, log10, int, sqrt, asin, acos, atan, abs.
