The solution of Piero is to define a map from a squa... | 677.169 | 1 |

As can be seen, the left projection works the same as the regular projection with the exception that the projection is perpendicular to the destination vector(vector B). there are several things that we can conclude from this. First, if the dot product is positive, the projection is toward the left of vector 'B'

Pie chart
In a pie chart, the arc length (and consequently, the central angle and the area) of each segment, is proportional to the quantity it represents. Together, the wedges create a full disk. A chart with one or more wedge separated from the rest of the disk is called an exploded pie chart.
Example

A PVector(100, 100) is not a point at (100,100) it's a vector from the origin (0,0) to point(100, 100). So your middle PVector is a vector from the origin to (350, 350). The angle of this vector is 45 degrees. Your Pos5 PVector is a vector from the origin to (550, 550);. The angle of this vector is also 45 d... | 677.169 | 1 |
The first two figures are congruent to each other. The third is a different size, and so is similar but not congruent to the first two; the fourth is different altogether. Note that congruences alter some properties, such as location and orientation, but leave others unchanged, like distances and angles. The latter sor... | 677.169 | 1 |
