Residual physics system

A system comprising:

• a first computing device comprising a first processor, a first memory and a first network interface;
• and
• a second computing device comprising a second processor, a second memory and a second network interface,
• wherein the first processor is configured by instructions stored in the first memory to carry out the method of:
• receive physics data;
• run a first simulation having a first attribute, using the physics data, to provide a first physics state;
• run a second simulation having a second attribute, using the physics data, to provide a second physics state;
• calculate a plurality of residuals, wherein each residual is the difference between the first physics state and the second physics state at a selected time;
• and
• synchronize the first physics state with the second physics state by applying one of the residuals to the first physics state;
• and
• wherein the second processor is configured by second instructions stored in the second memory to carry out the steps:
• receive physics data;
• run a third simulation having the first attribute, using the physics data, to provide a third physics state;
• receive the first residual from the first computing device;
• and
• synchronize the third physics state with the second physics state by applying the first residual to the third physics state.

A computer-readable medium comprising a computer program comprising machine-readable instructions that when implemented by a computing device cause the computing device to implement a method, at a first computing device, comprising:

• receiving physics data;
• running a first simulation having a first attribute, using the physics data, to provide a first physics state;
• running a second simulation having a second attribute, using the physics data, to provide a second physics state;
• calculating a plurality of residuals, wherein each residual is the difference between the first physics state and the second physics state at a selected time;
• and
• synchronising the first physics state with the second physics state by applying one of the residuals to the first physics state.
