Smooth manipulation of three-dimensional objects |
摘要 |
Systems and methods for manipulating a virtual three-dimensional (3D) object in a virtual 3D space are provided. A representation of the 3D object is displayed on a display. A non-hemispherical arcball having a surface is determined. The non-hemispherical arcball is associated with the representation of the 3D object. A pointing device is detected at a first position and at a second position. The first position of the pointing device is translated onto a first location on the surface of the non-hemispherical arcball. The second position of the pointing device is translated onto a second location on the surface of the non-hemispherical arcball. A rotation of the representation of the 3D object is displayed on the display, the rotation based on a path of travel between the first location and the second location along the surface of the non-hemispherical arcball. |
