Homogeneous coordinates are so called because they treat Euclidean and ideal points in the same way. Homogeneous coordinates are widely used in computer graphics because theyenable affine and projective transformations to be described as matrix manipulations in a coherent way. Why do we need homogeneou...
Homogeneous coordinates are often used in computer graphics and computer vision applications especially for the representation of geometric transformations. The homogeneous coordinates enable us to represent translation, rotation, scaling and projection operations in a unique way and handle them properly. Toda...

Homogeneous coordinates are very useful and fundamental concept in computer graphics, such as projecting a 3D scene onto a 2D plane. 现在我们就可以在 C ≠ D 的情况得到一组解 (x, y, 0),代入得 (C - D)w = 0,因为 C ≠ D,所以 w = 0。因而,两条平行线相交于投影空间中无限远处的一点 ...
AMD and Intel both have processors that incorporate a graphics processing unit (GPU) or FPGA and one or more traditional x86 cores on the same chip. AMD's Fusion line and Intel's Sandy Bridge are the first set of devices to incorporate a processor and GPU in the same die. Intel's ...
