Baking normals in zbrush 4 driver#

Beam tracing Modification of ray tracing which instead of lines uses pyramid-shaped beams to address some of the shortcomings of traditional ray tracing, such as aliasing. Barycentric coordinates Three-element coordinates of a point inside a triangle. Typically used for generating lightmaps, normal maps, or low level of detail models. Baking Performing an expensive calculation offline, and caching the results in a Texture map or Vertex attributes. B Back-face culling Culling (discarding) of polygons that are facing backwards from the camera. A compromise between the traditional GL API and other high-performance low-level rendering APIs.

:вЂЉ917 AZDO Approaching zero driver overhead, a set of techniques aimed at reducing the CPU overhead in preparing and submitting rendering commands in the OpenGL pipeline. Augmented reality Computer-rendered content inserted into the user's view of the real world. Array texture A form of texture map containing an array of 2D texture slices selectable by a 3rd 'W' texture coordinate used to reduce state changes in 3D rendering. anti aliasing methods for filtering and sampling to avoid visual artefacts associated with the uniform pixel grid in 3D rendering. Anisotropic filtering Advanced texture filtering improving on Mipmapping, preventing aliasing while reducing blur in textured polygons at oblique angles to the camera. Contrasts with Empirical models based purely on recorded data. :вЂЉ446 Analytic model A mathematical model for a phenomenon to be simulated, e.g. Ambient occlusion (AO) Effect approximating, in an inexpensive way, one aspect of global illumination by taking into account how much ambient light is blocked by nearby geometry, adding visual clues about the shape. Ambient lighting An approximation to the light entering a region from a wide range of directions, used to avoid needing an exact solution to the rendering equation. extending an RGB image) or standalone channel controlling alpha blending. Alpha channel An additional image channel (e.g. Aliasing Unwanted effect arising when sampling high-frequency signals, in computer graphics appearing e.g. Affine texture mapping Linear interpolation of texture coordinates in screen space without taking perspective into account, causing texture distortion. Also known as linear dodge in some applications. Additive blending A compositing operation where d s t = d s t + s r c, without the use of an alpha channel, used for various effects. A AABB Axis aligned bounding box (sometimes called 'axis oriented'), a bounding box stored in world coordinates one of the simplest bounding volumes. 4Г—4 matrix A matrix commonly used as a transformation of homogeneous coordinates in 3D graphics pipelines. 4D vector a common datatype in graphics code, holding homogeneous coordinates or RGBA data, or simply a 3D vector with unused W to benefit from alignment, naturally handled by machines with 4-element SIMD registers. 3D paint tool A 3D graphics application for digital painting of multiple texture map image channels directly onto a rotated 3D model, such as zbrush or mudbox, also sometimes able to modify vertex attributes 3D unit vector A unit vector in 3D space. 3D scene A collection of 3D models and lightsources in world space, into which a camera may be placed, describing a scene for 3D rendering.

3D graphics pipeline A graphics pipeline taking 3D models and producing a 2D bitmap image result. Rendering whose result looks 3D while actually not being 3D or having great limitations, e.g. 2D vector a two-dimensional vector, a common data type in rasterization algorithms, 2D computer graphics, graphical user interface libraries. 2D image 2D texture map A texture map with two dimensions, typically indexed by UV coordinates. 2D convolution Operation that applies linear filtering to image with a given two-dimensional kernel, able to achieve e.g. 0вЂ“9 7e3 format A packed pixel format supported by some graphics processing units (GPUs) where a single 32-bit word encodes three 10-bit floating point color channels, each with seven bits of mantissa and three bits of exponent.
