A non-transitory storage medium stores instructions executable by an information processing device including an operation device and a display. The instructions cause the information processing device to: display a first image; display a cropping frame for cropping of the first image when the operation device accepts a user operation for displaying the cropping frame in a state in which the first image is displayed; rotate the first image about a center of the cropping frame when the operation device accepts a user operation for rotating the first image in a state in which the first image and the cropping frame are displayed; and rotate the first image about a center of the first image when the operation device accepts a user operation for rotating the first image in a state in which the first image is displayed, and the cropping frame is not displayed.

Managing volumetric data, including: defining a view volume in a volume of space, wherein the volumetric data has multiple points in the volume of space and at least one point is in the view volume and at least one point is not in the view volume; defining a grid in the volume of space, the grid having multiple cells and dividing the volume of space into respective cells, wherein each point has a corresponding cell in the grid, and each cell in the grid has zero or more corresponding points; and reducing the number of points for a cell in the grid where that cell is outside the view volume.

Augmented and virtual reality display systems increase viewer comfort by reducing viewer exposure to virtual content that causes undesirable accommodation-vergence mismatches (AVM). The display systems limit displaying content that exceeds an accommodation-vergence mismatch threshold, which may define a volume around the viewer. The volume may be subdivided into two or more zones, including an innermost loss-of-fusion zone (LoF) in which no content is displayed, and one or more outer AVM zones in which the displaying of content may be stopped, or clipped, under certain conditions. For example, content may be clipped if the viewer is verging within an AVM zone and if the content is displayed within the AVM zone for more than a threshold duration. A further possible condition for clipping content is that the user is verging on that content. In addition, the boundaries of the AVM zone and/or the acceptable amount of time that the content is displayed may vary depending upon the type of content being displayed, e.g., whether the content is user-locked content or in-world content.

The embodiments of the present disclosure disclose subsurface scattering calculation method for translucent material rendering, which relates to the clipping and polynomial fitting of brute-force Monte Carlo photon tracking experimental results to accurately represent the energy attenuation of subsurface scattering in distance. On this basis, an average free path and a single scattering rate are used to determine the relationship of each term in the multinomial fitting formula so as to facilitate the calculation and adjustment of the reflection profile. In the end, through a new real-time importance sampling solution, the outgoing radiation from any point on the object surface is calculated by the Monte Carlo method. This importance sampling solution is also applicable to any other subsurface scattering calculation model. By combining this subsurface scattering calculation result with other results, such as highlight reflection, any translucent material object can be rendered accurately and efficiently.
