Hi, I need some helo about Delphi APIs. In JAVA frequently used an API called "OpenSpurcePhysics". It was made for physcicsts, and containd a lot of numerical method (numerical integration of differentieal equations, matrix operations, etc.) and when I wanted to use any of theese, I just imported this API, and simply called a function with parameters (e. g. Runge-Kutta method for solving dínamical equations step-by-step for motion simulations).But the mostly used feature of this was the easy plotting caculated curves, or drawing e.g. orbits of satelites. JAVA has very-very sophisticated and superior, but extremely hard-to-use graphics abilities. For me (before i found OSP) it took extreme amoount time and energy to code the program parts thar plot my results - far more time than to write the parts that made the numerical simulations, soltions, snd so on. Anyway, cpuld anyone tell me it there is something similar to the JAVA OpenSourcePhysics in Delpy also? I think large numbers of scientists use Delphi for their work and maybe (I hope) a mathematical method libreery including the plotting functions were written by someone. It woidl be great. Thank íou for your answer. zmezzo
