Both VISA CVV and MC CVC are 3-or 4-bit numbers generated by the card number, expiration date, and service constraint code, and are generally written in the 2-track user-defined data area of the card stripe. CVV and CVC generation methods are the same, but the names are not the same.
CVV2 and CVC2 are also the card verification values obtained by the same algorithm, but are printed on the signature strip
distance between Y and C is equal to the ratio obtained by the length of CD. It is easy to understand it by using a mathematical expression:
In this way, each vertex from A to B corresponds to the unique Vertex on C to D. If there is an X, we can obtain an y.In addition, if X is not in [a, B], for example, x

Perspective Projection Transformation
With the above two theoretical knowledge, we began to analyze the pivot projection transformation, the main character of this analysis. Here we use OpenGL's Perspective Projection Transformation for analysis. Other APIs may have some differences, but the subject idea is similar and can be deduced similarly. After the transformation of the camera matrix, the vertex is transformed to the camera space. At this time, the polyg
multiplication while d3d uses row vector matrix multiplication.
(3) The Z range of OpenGL CVV is [-1, 1], and the Z range of d3d CVV is [0, 1].
These differences lead to the final differences between OpenGL and d3d Perspective Projection matrices.

space enters CVV after perspective transformation. This transformation matrix actually completes two tasks:
1) projects a vertex from a 3D space to a 2D projection plane.
2) the 2D projection points on the projection plane are transformed to the CVV in the same cropping space by linear interpolation.
These transformations are all completed once through the perspective matrix (if you are not familiar with

In reality, the classification of the above-mentioned plane projection can continue to be subdivided. For example, the Perspective Projection can be divided into one drop point, two drop points, and three drop point perspective projection. Side projection can be further divided into scatter projection and oblique two-axis projection. Orthogonal projection can be divided into axial-side projection and multi-viewpoint orthogonal projection. If you are interested in this, you can refer to t
