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.
The ability to export .3DS, .OBJ, .VTX and .C files for use in external programs; Plug-in support, using the Anim8or Scripting Language, also known as ASL for short; 3D object browser to allow the user to view 3D files in a specified directory; Textures in .BMP, .GIF and .JPG formats; Environment maps, bump maps, transparency, specularity ...
Transparency information can be included, allowing rendered foreground objects to be composited with photographs or video. It is also sometimes useful to store the contributions of different lights, or of specular and diffuse lighting, as separate channels, so lighting can be adjusted after rendering.
Materials can be transparent. This is referred to as being dissolved. Unlike real transparency, the result does not depend upon the thickness of the object. A value of 1.0 for "d" (dissolve) is the default and means fully opaque, as does a value of 0.0 for "Tr". Dissolve works on all illumination models.
A color spectrum image with an alpha channel that falls off to zero at its base, where it is blended with the background color.. 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]
XCF, short for eXperimental Computing Facility, [1] is the native image format of the GIMP image-editing program. It saves all of the data the program handles related to the image, including, among others, each layer, the current selection, channels, transparency, paths and guides.
Blender, for example, had no option to create a cryptomatte image before version 2.80. [6] With version 2.80, only the "Cycles" path-tracing render engine supported creating a cryptomatte whereas "Eevee", the newly added real-time render engine, did not.
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.
