Member Function Documentation

Point Geom::Point::ccw

(

)

const

Return a point like this point but rotated -90 degrees.

(If the y axis grows downwards and the x axis grows to the right, then this is 90 degrees counter-clockwise.)

Point Geom::Point::cw

(

)

const

Return a point like this point but rotated +90 degrees.

(If the y axis grows downwards and the x axis grows to the right, then this is 90 degrees clockwise.)
