Abstract: An approach is disclosed that receives a time sequence of low-resolution images, each of the low-resolution images depicting a physics event. The approach interpolates two adjacent low-resolution images to a higher spatial-resolution interpolated image between a first and a second time. The approach then inputs a previous high-resolution image and the interpolated image to a neural network that includes a physics constraint that corresponds to the physics event. A new high-resolution image is received from the neural network, with the new image corresponding to the inputted previous high-resolution image and the interpolated image. The neural network is trained to minimize the mean squared difference between a smoothed version of the output and the input at the same time plus the difference between the high-resolution output and a second relevant physics equation.

Abstract: Some techniques are described herein for conditionally rendering assets. In some examples, such techniques include a computer system receiving a request to render an asset and, in response, measuring performance of the computer system to determine whether to initiate rendering of the asset. For example, the computer system can measure the performance by rendering another asset that is less complex and/or resource intensive as the asset so to estimate a result of rendering the asset. Other techniques are described herein for rendering assets in different manners. In some examples such techniques include a computer system receiving a request to render an asset and, in response, rendering the asset in different manners depending on one or more aspects of the file and one or more current performance measurements of the computer system. Other techniques are described herein for rendering a 3D model based on current performance measurements of a computer system.
