Study on Axsometric Scale in Perspective Projection (3)
When the picture plane is not perpendicular to the ground plane, there exist three vanishing points. In this case, we studied on a method to draw a perspective by using axsometric scale.For a straight line, lying on the ground plane and parallel to x or y axis, axsometric scale is intersecting points of total perspect of this straight line and a group of straight lines.They are total perspects of parallels lying on the ground plane. Inclination angles of parallels to both axes are 45° and their intervals are constant.For a straight line, parallel to z axis, axsometric scale is intersecting points of total perspect of this straight line and a group of straight lines. They are total perspects of parallels lying on a plane on which this straight line lies. Parallels are horizontal and their intervals are constant.
