In a 32-bit frame buffer there are 24 bits of color, 8 each for red, green, and blue, along with an 8-bit alpha channel.Ī global level of artificial illumination that ensures all surfaces are visibly lit, particularly those without direct illumination. new pixel = (alpha)(pixel A color) + (1 - alpha)(pixel B color)Īlpha Buffer / Alpha Channel / Alpha PlaneĪn extra Color channel to hold transparency information pixels become quad values (RGBA). Typically, alpha has a normalised value of 0 to 1 for each color pixel. The resultant color of a pixel is a combination of the foreground and background color.
It is implemented by rendering polygons through a stipple mask with an on-off density proportional to the transparency of the object. The rendering stage, which is critical for 3D image quality, creates a two dimensional display from the polygons created in the geometry stage.Ī technique in graphics processing that simulates transparency or translucency for objects or layers - the real world is composed of transparent, translucent, and opaque objects and alpha blending mimics this by adding transparency information for translucent objects. The geometry stage includes transformation, lighting, and setup. In the tessellation stage, a described model of an object is created, and the object is then converted to a set of polygons. The process of 3D graphics can be divided into three-stages: tessellation, geometry, and rendering. If you've been on the hunt for the perfect sea-inspired ink and need a few more inspiration pieces to add to your Pinterest board, here are 15 ocean tattoo ideas that'll make you feel like an actual mermaid.Come commonly used graphics terminology explained here at ĭisplayed representation of a scene or an object along two axes of reference: height and width (x and y).ĭisplayed representation of a scene or an object that appears to have three axes of reference: height, width, and depth (x, y, and z). From marine-based animals like an octopus or sea otter to symbols like seashells, there's more than one way to get a water-themed tattoo. But if you're looking for an ocean tattoo that's a bit different, know that you don't have to go with a literal art piece. One of the most popular trends in ink right now is the micro tattoo, and you can opt for an ocean-inspired design within that category - think small, single-line waves.
