Commonly, 3D geometry with transparency is rendered by blending (using alpha compositing) all surfaces into a single buffer (think of this as a canvas).Each surface occludes existing color and adds some of its own color depending on its alpha value, a ratio of light transmittance.
In computer graphics, alpha compositing or alpha blending is the process of combining one image with a background to create the appearance of partial or full transparency. [1] It is often useful to render picture elements (pixels) in separate passes or layers and then combine the resulting 2D images into a single, final image called the composite .
Alpha to coverage [1] [2] [3] is a multisampling computer graphics technique, that replaces alpha blending with a coverage mask. This achieves order-independent transparency for when anti-aliasing or semi-transparent textures are used. This particular technique is useful for situations where dense foliage or grass must be rendered in a video ...

Just last year, the for-profit nursing home Princeton Care Center’s abrupt and chaotic 24-hour shutdown disrupted, displaced, and, in some cases, traumatized the lives of 72 nursing home ...
Alternatively, other therapists consider themselves to be more theoretically grounded as they blend their theories; they are called integrative psychotherapists and are not only concerned with what works, but also why it works. [3]
This image has partial transparency (254 possible levels of transparency between fully transparent and fully opaque). It can be transparent against any background despite being anti-aliased. Some image formats, such as PNG and TIFF, also allow partial transparency through an alpha channel, which solves the edge limitation problem.
