Abstract: Disclosed is an animation method of deformable objects using an oriented material point and generalized spring model. The animation method comprises the following steps of: modeling a structure of a deformable object into oriented material points and generalized springs; initializing forces and torques acting on the material points, calculating the forces acting on the material points owing to collision of the material points and gravity, calculating the spring forces and torques acting on the material points, obtaining new positions and postures of the material points; updating positions, velocities, postures and angular velocities of the material points based upon physics, and displaying and storing updated results. The oriented material point and generalized spring model of the invention contains the principle of the conventional mass-spring model, but can animate deformable objects or express their structures in more intuitive manner over the conventional mass-spring model. Also, the material point and generalized spring model of the invention can express elongate deformable objects such as hair and wrinkled cloth, which cannot be expressed in the prior art, so as to animate features of various objects.

Abstract: Disclosed herein is an apparatus for producing 3D sound. The apparatus includes a determination unit, a mono sound spreading unit, a stereo sound spreading unit, a selection unit, and a 3D sound accelerator. The determination unit receives a source sound file and determines whether the source sound file is mono or stereo. The mono sound spreading unit converts the source sound into pseudo-stereo sound and performs sound spreading on the pseudo-stereo sound, if the source sound is determined to be mono. The stereo sound spreading unit performs sound spreading on the source sound, if the source sound is determined to be stereo. The selection unit receives the output of the mono sound spreading unit or stereo sound spreading unit, and transfers the output to headphones if the headphone reproduction has been selected. The 3D sound accelerator receives the output from the selection unit if speaker reproduction has been selected, removes crosstalk from the output, and transfers the crosstalk-free output to speakers.

Abstract: An OSD apparatus for displaying an image using first and second video input signals and a blend coefficient value comprises a region search device for generating an output signal, wherein the output signal is responsive to Human Visual System (HVS) characteristic elements and the first and second video input signals, and an &agr; controller responsive to the blend coefficient value and the output signal from the region search device. Preferably, contrasts of the first and second video input signals are used as one of the HVS characteristic elements. In particular, the contrasts of the first and second video input signal are obtained by selectively considering contrast of at least one of horizontal, vertical, and diagonal directions. Alternatively, the contrast is obtained by using a Y component when the first and second video input images are YUV images.
