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.
Also known as alpha blending, or alpha compositing this technique reduces popping by displaying both LODs of a 3D model simultaneously and blending them together over a small transition period. [2] During the blending process an alpha value is specified for each LOD, which determines transparency of objects. At the beginning of the transition ...
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.
A variation of a bitmap image or alpha blending calculation in which the RGB color values are assumed to be already multiplied by an alpha channel, to reduce computations during alpha blending; uses the blend operation: dst *= (1 - alpha) + src; capable of mixing alpha blending with additive blending effects Primitive
vs_2_a/ps_2_x with instancing and additional shader caps, 4K textures, multiple render targets (4 MRTs), floating-point blending (limited), all 9_2 features. 10_0 Shader Model 4.0, geometry shader, stream out, alpha-to-coverage, 8K textures, MSAA textures, 2-sided stencil, general render target views, texture arrays, BC4/BC5, full floating ...
A sketch colored digitally with use of several different blend modes in order to preserve the pencil lines and paper texture below the color layers. Blend modes (alternatively blending modes [1] or mixing modes [2]) in digital image editing and computer graphics are used to determine how two layers are blended with each other.
90 million fully featured pixels/sec sustained fill rate for bilinear textures, with LOD MIP-mapping, Z-buffering, alpha-blending and fogging enabled). 3 million fully featured triangles/sec (Filtered, LOD MIP-mapped, Z-buffered, alpha-blended, fogging enabled, textured triangles). 180 million pixel/sec with scanline interleaved configuration.
Per-pixel lighting is commonly used with techniques, such as blending, alpha blending, alpha to coverage, anti-aliasing, texture filtering, clipping, hidden-surface determination, Z-buffering, stencil buffering, shading, mipmapping, normal mapping, bump mapping, displacement mapping, parallax mapping, shadow mapping, specular mapping, shadow ...
