Because of errors associated with floating point arithmetic, we do not . well, think where the location at (i,j) goes when rotating 90 degrees. To rotate any point by 90 degrees in clockwise direction we can follow three simple steps: Step 1: Plot the point on a coordinate plane.PI/180; public static Vector Rotate(this Vector v, double degrees) return v.Geometry – Transformation – Rotation not around originHow do you rotate a shape around a point other than the origin?This geometry video explores the rotatin. This will turn the forward vector 90 degrees to the right. var rotatedPoint = originalPoint * transform; The math for 2D rotations is actually quite simple, so using two new object types might seem like overkill. Note: You can rotate the selection by a number of degrees during the interactive transform mode by typing in a value followed by the letter R while your left mouse key is still pressed. The following image should illustrate my point. (4 x 3) matrix turns into (3 x 4) matrix : Matrix B (3 * 4) You can change the matrix coordinate points with a formula: B [i , j] = A [4 – (j – 1) , i] Example:If we want to rotate a vector given by (x, y) by 90 degrees in the counter-clockwise direction using the rotation matrix then the new coordinates are given as (-y, x). rotated[j][n-i-1] = v[i][j]; } } return rotated; } This function takes a 2D vector as input and returns a new 2D vector that is rotated 90 degrees clockwise.First determine the size of the matrix that has been rotated 90 degrees, If you rotate it 90 degrees, the rows become columns and the columns become rows. In 3d the cross product a x b of two vectors a and b results in a vector p := a x b that is perpendicular to both a and b.up); // handle case where start is colinear with up. Step 2: Rotate the vector by 45 degrees twice. One way to make it work is get the input of rows and cols from user and make a one dimensional array dynamically.” Here’s how you can do it: Write down the vector you want to rotate in its original form.Now, unity provides a handy method to convert two vectors to a rotation: Quaternion.
