All graphical elements can be specified in a textual source file that can be compiled into a binary file or one of two text representations. CGM provides a means of graphics data interchange for computer representation of 2D graphical information independent from any particular application, system, platform, or device.
Generic applications can be written in a natural notation, e.g. v += A*q - w;, while the library dispatches to the appropriate algorithms: matrix vector products vs. matrix products vs. vector scalar products etcetera. The goal is to encapsulate performance issues inside the library and provide scientists an intuitive interface.
Each iteration of the Sierpinski triangle contains triangles related to the next iteration by a scale factor of 1/2. In affine geometry, uniform scaling (or isotropic scaling [1]) is a linear transformation that enlarges (increases) or shrinks (diminishes) objects by a scale factor that is the same in all directions (isotropically).
A scaling can be represented by a scaling matrix. To scale an object by a vector v = (v x, v y, v z), each point p = (p x, p y, p z) would need to be multiplied with this scaling matrix: = []. As shown below, the multiplication will give the expected result:
Scale co-occurrence matrix (SCM) is a method for image feature extraction within scale space after wavelet transformation, proposed by Wu Jun and Zhao Zhongming (Institute of Remote Sensing Application, China). In practice, we first do discrete wavelet transformation for one gray image and get sub images with different scales.
The template can accept parameters that describe the size of the object on the screen: |viewport_cm= or |viewport_px=. The template also accepts other geohack parameters to generate the scale argument: dim; type (e.g., "mountain" or "city") population (for type="city" only)
Pencil2D is a free and open-source 2D animation software for Windows, macOS, and Unix-like operating systems. It is released under the GNU General Public License and uses the Qt framework . It is used for making cartoons using traditional techniques (tracing drawings, onion skinning , etc), managing vector and bitmap drawings.
