Briefly, in accordance with one or more embodiments, a processor receives an incoming data stream that includes alpha channel data, and a memory stores an application programming interface (API). The API is to route the alpha channel data to a fixed point blending unit to perform one or more blending operations using fixed point representation of the alpha channel data. The API is further to route the incoming data stream to a floating point blending unit to perform operations involving floating point representation of the incoming data.

In some examples, an apparatus obtains source layer pixels, such as those of a content image and first destination layer pixels, such as those of a destination image. The first destination layer pixels have associated alpha values. The apparatus obtains information that indicates a first blending color format for the alpha values. The first blending color format is different from a first destination layer color format for the first destination layer pixels and an output color format for a display. The apparatus converts the source and/or first destination layer pixels to the first blending color format. The apparatus generates first alpha blended pixels based on alpha blending the source layer pixels with the first destination layer pixels using the associated alpha values. The apparatus provides, for display on the display, the first alpha blended pixels.

Methods and systems for manufacturing an orthodontic appliance with an object incorporated in a surface thereof comprising: acquiring a preliminary appliance 3D digital model; acquiring an object 3D digital model; obtaining a desired coupling location of the object on the orthodontic appliance; positioning the object 3D digital model onto a surface of the preliminary appliance 3D digital model based on the obtained coupling location; causing an initial predetermined degree of penetration; merging the object 3D digital model with the preliminary appliance 3D digital model to generate an appliance 3D digital model of the orthodontic appliance with the object incorporated in the surface; and storing the appliance 3D digital model in an internal memory of the electronic device.

Systems, apparatuses and methods may provide away to blend two or more of the scene surfaces based on the focus area and an offload threshold. More particularly, systems, apparatuses and methods may provide a way to blend, by a display engine, two or more of the focus area scene surfaces and blended non-focus area scene surfaces. The systems, apparatuses and methods may include a graphics engine to render the focus area surfaces at a higher sample rate than the non-focus area scene surfaces.

The disclosure provides a mixed rendering system and a mixed rendering method. The mixed rendering system includes a client device configured to perform: determining at least one user-interactable object of a virtual environment; rendering the at least one user-interactable object; receiving a background scene frame of the virtual environment; blending the at least one rendered user-interactable object with the background scene frame as a visual content of the virtual environment; and providing the visual content of the virtual environment.

A computer-implemented method for lighting subjects for artificial reality scenes may include (i) identifying (a) a physical camera configured to capture a physical subject for insertion into an artificial reality scene, (b) a physical light source that is positioned such that the physical light source lights the physical subject recorded by the physical camera, and (c) lighting conditions in the artificial reality scene, (ii) determining at least one lighting parameter to light the physical subject such that lighting conditions of the physical subject blend visually with the lighting conditions in the artificial reality scene, and (iii) configuring the physical light source to light the physical subject according to the at least one lighting parameter. Various other methods, systems, and computer-readable media are also disclosed.

A picture rendering method, a storage medium, and an electronic apparatus are provided. The method includes: obtaining one or more target images for a two-dimensional (2D) virtual scene, each of the one or more target images including a background, a character object moving in the background image, and a target object located at a fixed position in the background; determining a first depth value of a first pixel on the target object in the background by using a depth offset indicated in a depth map corresponding to the target object, the depth map recording a depth offset of each first pixel on the target object; obtaining a second depth value of a second pixel on the character object moving to a target display position; and rendering the one or more target images according to the first depth value and the second depth value.

Particular techniques for generating synthetic images and/or for training machine learning model(s) based on the generated synthetic images. For example, training a machine learning model based on training instances that each include a generated synthetic image, and ground truth label(s) for the generated synthetic image. After training of the machine learning model is complete, the trained machine learning model can be deployed on one or more robots and/or one or more computing devices.

The present disclosure relates to methods and apparatus for display processing. For example, disclosed techniques facilitate regional processing of images for under-display device displays. Aspects of the present disclosure can identify a subsection of a set of frame layers, the identified subsection corresponding to a lower pixel density region, relative to at least one other region, of a display. Aspects of the present disclosure can also blend first pixel data for each frame layer corresponding to the identified subsection to generate second pixel data. Further, aspects of the present disclosure can populate a buffer layer based on the second pixel data. Additionally, aspects of the present disclosure can blend pixel data from the set of frame layers and the buffer layers to generate a blended image. Aspects of the present disclosure can also transmit the blended image for presentment via the display.
