Hello. Is there some easy way to convert screen coordinates (origin at the top left corner) to Cartesian coordinates?
Screen coordinates refer to the x and y values used to locate a point on a computer screen, with the origin typically being the top left corner of the screen. Cartesian coordinates, on the other hand, refer to the x, y, and z values used to locate a point in a three-dimensional space. The origin in Cartesian coordinates is typically the center of the coordinate system.
To convert screen coordinates to Cartesian coordinates, you can use the formula x = x_screen - (screen_width / 2) and y = (screen_height / 2) - y_screen. This will give you the x and y values in Cartesian coordinates, with the origin at the center of the screen.
Converting screen coordinates to Cartesian coordinates is important when working with three-dimensional graphics and animations. Cartesian coordinates allow for more precise positioning of objects in a three-dimensional space, while screen coordinates are limited to a two-dimensional plane.
Screen coordinates are limited to a two-dimensional plane, which means they cannot accurately represent objects in a three-dimensional space. They are also dependent on the size and resolution of the screen, making it difficult to ensure consistency across different devices.
To ensure accuracy when converting between screen coordinates and Cartesian coordinates, it is important to consider the size and resolution of the screen, as well as the position of the origin in each coordinate system. It may also be helpful to use mathematical functions or libraries specifically designed for this conversion.
