Ray Tracing in One Weekend - Real-Time Rendering

in 3D. A is the ray origin and B is the ray direction. The ray parameter t is a real number (float in the code). Plug in a different t and p ( t) moves the point along the ray. Add in negative t a nd you can go anywhere on the 3D line. For positive t, you get only the parts in front of A , and this

Fluid Dynamics and the Navier-Stokes Equation - UMD

May 17, 2012 · Vector fields are useful in the study of fluid dynamics, since they make it possible to discern the approximated path of a fluid at any given point [12]. Vector Calculus . ... equations, by tracing a path back starting at X (which is, given Origin O, cell (i, j, k

Vector data may be topological or non-topological. ARC/INFO coverages are topological and shapefiles ... example, by placing a cylinder tangent to a lighted globe, a projection can be made by tracing the lines of longitude and latitude onto the cylinder. The cylinder in this case is the projection surface, and the globe is

Supplementary Notes: Stereonets

The pole (or normal vector) of a plane allows the plane to be represented on the stereonet as a single point. Pole plots are a convenient way to examine the orientation of a large number of discontinuities, such as that measured during a discontinuity scanline survey. 90° Wyllie & Mah (2004) When the tracing paper is rotated so

A Guide to Reading and Understanding the EKG

EKG Tracing Please refer to the EKG tracing below if you are not familiar with the labeling of the EKG waveforms. Figure 1- EKG Tracing Step 1 Rate The first step is to determine the RATE, which can be eyeballed by the following technique. Locate the QRS (the big spike) complex that is closest to a dark vertical line. Then count either forward or

Computer Graphics Lecture Notes - Dynamic Graphics Project

When written with parentheses and commas separating elements, consider a vector to be a column vector. That is, (x,y) = x y . Row vectors are denoted with square braces and no commas: x y = (x,y)T = x y T. The set of real numbers is represented by R. The real Euclidean plane is R2, and similarly Eu-clidean three-dimensional space isR3. The set ...
