VRAM is dedicated memory on the graphics card used to store and quickly access textures, shaders, and other graphical data. More VRAM allows for smoother rendering of high-resolution textures and complex scenes. However, having excessive VRAM beyond what is needed for your intended usage does not...
A pixel shader is a type of computer graphics tool that allows for the creation of image effects like light, texture, shape, and...
That’s a problem big enough to overload a microprocessor. In a modern 2880x1800 retina display running at 60 frames per second that calculation adds up to 311,040,000 calculations per second. How do graphics engineers solve this problem? This is when parallel processing becomes a good soluti...
In computer graphics, a pixel shader, also known as a fragment shader, is a program that dictates the color, brightness, contrast, and other characteristics of a single pixel (fragment). A programmer who specializes is writing pixel shader programs is known as a shading artist....
A graphics card, or GPU (graphics processing unit), is a specialized electronic circuit designed to handle and accelerate the creation and rendering of images, videos, and animations. It is a crucial component in a computer system, especially for tasks requiring high-performance graphics, such as...
What role does video random access memory (VRAM) play in graphics card performance? VRAM is dedicated memory on the graphics card used to store and quickly access textures, shaders, and other graphical data. More VRAM allows for smoother rendering of high-resolution textures and complex scenes....
In 3D computer graphics, anisotropic filtering (abbreviated AF) is a method of enhancing the image quality of textures on surfaces of computer graphics that are at oblique viewing angles with respect to the camera where the projection of the texture appears to be non-orthogonal. ...
On the most fundamental level, OpenGL is a software interface that allows a programmer to communicate with graphics hardware. Of course, there is much more to it than that, and you will be glad to know that this book explains the finer details of OpenGL. But before we get our hands dirty...
The DXCache folder houses what is known as the DirectX Shader Cache. But what is a shader cache? When games or applications run, they often use shaders – small programs that help render graphics. As these shaders get compiled, it takes some time, and to avoid this repetitive compilation...
What is Fermi?(6) 全新的PolyMorph引擎 DX11当中的重大改进莫过于Tessellation(曲面细分)技术了,而转换到GF100核心上之后,就是PolyMorph Engine(多形体引擎)。NVIDIA的PolyMorph引擎的作用有些类似于ATI HD5870显卡当中的Graphics Engine(图形引擎),两者之间的区别在于HD5870显卡上仅有一组Graphics Engine(图形引擎)来...
