Vector Gem vs Drawing with Math

Vector Gem allows the input and three-dimensional display of vectors, lines and planes. The input supports different forms (e.g. linear equation, vector form, normalized form, ...) Vector Gem can display the starting point, the direction vectors and the normalized vector for each plane and calculate the intersection points with the axes. For lines it can display the starting point and the direction vector and calculate the points of intersection with the coordinate planes. The color can be selected for each object along with different settings for the display.

Our “Drawing with Math (Vector and Pixel Art)” app combines two main components: * uniquely versatile image editors, * various methods of linear transformations of both user-entered and system images. Image editors are available in vector and pixelated forms. The editors offer such options as: * free drawing, * entry of all standard shapes, * entry of regular Cartesian, polar, or parametric function into image editor. List of several visually appealing functions is provided. The App stores 10 most recent user entries for each type. Vector images can be linearly transformed in a variety of user-defined ways: * 2x2 matrix, * eigenvalues and eigenvectors, * rotation by degree, * reflection across a given vector. Pixelated images can be compressed by segments to user-selected rank. Mathematical context for the above is provided, whenever possible. Explanation of image compression algorithms requires significant understanding of Linear Algebra, and is available in our “Matrix Solver Step by Step” app. Several bonus images with animations and editable greeting cards are also available.
