ABSTRACT:
An image processing method and an image processor for drawing the movements of such linear objects as fur, hair, and grass of a turf being influenced by wind have not been proposed thus far. The present invention provides image processing method executed by an image processor for projecting and drawing linear objects viewed from view point on a two-dimensional plane when the view point, ground, and linear objects, of which one end of each linear object is fixed on the ground, are positioned in virtual three-dimensional space, comprising a drawing step of layering the cross-sections of linear objects created by cutting the plurality of linear objects at planes which are parallel with the ground for each of planes as semi-transparent layers, and a redrawing step of moving the semi-transparent layers in a predetermined direction after a predetermined time elapsed and redrawing the semi-transparent layer(s) on the two-dimensional plane.
