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.
Rebelle is a raster graphics editor for digital painting and drawing, designed to simulate oils, acrylics, watercolors, pencils and other traditional paint media on a digital canvas. It is developed and published by the Slovak company Escape Motions. The software is intended to be used by everyone interested in digital painting, from children ...
In 3D computer graphics, ray tracing is a technique for modeling light transport for use in a wide variety of rendering algorithms for generating digital images. On a spectrum of computational cost and visual fidelity, ray tracing-based rendering techniques, such as ray casting, recursive ray tracing, distribution ray tracing, photon mapping ...
Texture mapping. Mapping a two-dimensional texture onto a 3D model. 1: 3D model without textures. 2: Same model with textures. Texture mapping[1][2][3] is a method for mapping a texture on a computer-generated graphic. "Texture" in this context can be high frequency detail, surface texture, or color.
Perlin noise is a type of gradient noise developed by Ken Perlin in 1983. It has many uses, including but not limited to: procedurally generating terrain, applying pseudo-random changes to a variable, and assisting in the creation of image textures. It is most commonly implemented in two, three, or four dimensions, but can be defined for any ...
Paper texture limits what can be done with the calotype process. This texture can be seen by holding a piece of copier paper up to the light: the way fibers clump in the paper making process causes a relatively low contrast pattern that may remind one of bushes growing on a hillside. [8][9] This pattern persists when paper is waxed, as ...
Rendering or image synthesis is the process of generating a photorealistic or non-photorealistic image from a 2D or 3D model by means of a computer program. [citation needed] The resulting image is referred to as a rendering. Multiple models can be defined in a scene file containing objects in a strictly defined language or data structure.
Texture mapping Texture mapping is a method for adding detail, surface texture, or colour to a computer-generated graphic or 3D model. Its application to 3D graphics was pioneered by Edwin Catmull in 1974. A texture map is applied (mapped) to the surface of a shape, or polygon. This process is akin to applying patterned paper to a plain white box.
