WebJust subtract the exponents and you get 1x10 270, so that is roughly how much you can scale up a UE4 world in UE5's Large World Coordinate system. 2097152.0 units x 1x10 270 is about 2.09x10 276 units (in centimeters) or about 2.09x10 271 kilometers. The distance between the earth and sun is about 1.49x10 8 kilometers. Webscore:0. Single prec operations are faster and the data uses less memory less network bandwidth. So you only use double if you gain something in exchange for slower ops and more mem and bandwidth required. There are certainly applications of rigid body physics where the extra precision would be worth it, such as in manipulating lat\lon where ...
Double precision in physics engines? : r/learnprogramming - Reddit
WebDescription. There are generally two classes of physics engines: real-time and high-precision. High-precision physics engines require more processing power to calculate very precise physics and are usually used by scientists and computer animated movies. Real-time physics engines—as used in video games and other forms of interactive … There are generally two classes of physics engines: real-time and high-precision. High-precision physics engines require more processing power to calculate very precise physics and are usually used by scientists and computer animated movies. Real-time physics engines—as used in video games and other forms of interactive computing—use simplified calculations and decreased accuracy to compute in time for the game to respond at an appropriate rate for game play. dxvk wrapper windows

WebMax Physics Delta Time. This is the maximum time step that a simulation can take. If this is smaller than the tick of the engine, physics will move artificially slow in order to increase stability. Substepping. Defines whether to substep the physics simulation. This feature is still experimental. Webrelativistic many-body systems. Although the double value type (8 octets, 15-16 digits precision) is sufficient for a wide class of simulations, it involves unacceptable limitations [3] in some specific problems encountered in physics (e.g. in the natural system of unities, the magnitude order of the gravitational constant is 10-45 MeV-2 ...
