In computer graphics, a procedural texture [1] is a texture created using a mathematical description (i.e. an algorithm) rather than directly stored data. The advantage of this approach is low storage cost, unlimited texture resolution and easy texture mapping . [ 2 ]
Bump mapping [1] is a texture mapping technique in computer graphics for simulating bumps and wrinkles on the surface of an object. This is achieved by perturbing the surface normals of the object and using the perturbed normal during lighting calculations. The result is an apparently bumpy surface rather than a smooth surface, although the ...
A normal pointing to right of the texture (1,0,0) is mapped to (255,128,128). Hence the right edge of an object is usually light red. A normal pointing to top of the texture (0,1,0) is mapped to (128,255,128). Hence the top edge of an object is usually light green. A normal pointing to left of the texture (-1,0,0) is mapped to (0,128,128).
A Big Apple straphanger was shoved onto Manhattan subway tracks and struck by an incoming 1 train in a cowardly attack Tuesday — miraculously surviving the horrifying caught-on-video ordeal.
Russia's deputy U.N. ambassador said on Wednesday any decision by President-elect Donald Trump's incoming administration to cut support for Ukraine would be a "death sentence" for the Ukrainian ...
When excluding volatile food and energy costs, the so-called core PCE was down to 2.8% in November — compared with a peak of 5.6% in September 2022.
This shader works by replacing all light areas of the image with white, and all dark areas with a brightly colored texture. In computer graphics , a shader is a computer program that calculates the appropriate levels of light , darkness , and color during the rendering of a 3D scene —a process known as shading .
Legendary actress Glenn Close gave the Golden Globes censors a well-rounded glimpse at her choice vocabulary during Sunday night's live show.. The 77-year-old star appeared on stage toward the end ...
