摘要： This invention provides an apparatus and the like, which render an object from a predetermined view direction by a method using microfacet billboarding using 2D images obtained by photographing an object to be rendered from a plurality of photographing directions, and a depth image of the object to be rendered. This method obtains the geometrical shape of the object to be rendered on the basis of the depth image and the like, and approximates the geometrical shape using a set of microfacets whose directions change depending on the view direction. By mapping 2D images selected based on the view direction and photographing directions onto the respective microfacets as texture images, an arbitrary shaped object and landscape can be efficiently rendered.

摘要： An implicit function field of a nonmanifold is held in a form of volume data; a value of an implicit function at a point between lattice points is decided by interpolation; and if a difference in code distances between two adjacent voxels to be interpolated is larger than a fixed width, no surface is formed between the voxels. Furthermore, an entered curved surface is broken down into curved surface patches which enable determination of a front and a back; numbers are given to the front and the back, respectively, to be distinguished from each other; and a space is classified into a plurality of regions by using the number of a surface of a nearest point.

摘要： An alerting device allowing easy estimation of possible interference and useful suggestions to eliminate deteriorated communication quality due to interference is disclosed. A signal including a band used by a target radio communication system is selected from a received signal based on a prescribed system specification of the radio communication system. A detected signal level of the selected signal is detected and compared with the prescribed interference level. When the detected signal level is greater than the prescribed interference level, it is determined that interference occurs. Further, an interference source is estimated by analyzing the selected signal with respect to time and frequency components.

摘要： An optical transmission method which suppresses waveform distortion caused by an in-optical fiber non-linear optical effect in a long-distance coherent optical communication system. The modulation index of a transmitting station is increased or decreased with respect to the value at which the best receiver sensitivity is realized in a condition in which an optical fiber is not in its transmitting condition. Otherwise, the delay amount of a delay detection circuit of a receiving station is increased or decreased with respect to the value at which the best receiver sensitivity is realized in a condition in which the optical fiber is not in its transmitting condition.

摘要： An automatic frequency control system, for an optical coherent communication system, in which an output frequency of a local oscillator is swept by a frequency sweep signal FM-modulated with a frequency shift signal. The FM-modulated local frequency is combined with an input optical signal and heterodyne-detected. A frequency shift signal component derived from a heterodyne detection output is compared with the frequency shift signal to verify whether or not the local oscillation frequency is in a predetermined range with respect to the input signal frequency. When it is in the predetermined range, the system operates to terminate the frequency sweep signal and remove the frequency shift signal and is switched to oscillation frequency control of the local oscillator by using a d.c. component of the hterodyne detection output.

摘要： Two intermediate frequency signals, which are used in a polarization diversity optical heterodyne receiver operable according to demodulation and subsequent combination and have a common intermediate signal frequency variable in an intermediate frequency range, are subjected to delaying relative to each other and then combined into a combined intermediate frequency signal. A frequency discriminator (24) discriminates the intermediate signal frequency of the combined intermediate frequency signal to produce a control signal for use in stabilizing a local optical frequency of a local beam used in combination with a signal beam susceptible to polarization fluctuation. A delay may be given for the delaying to one of the two intermediate frequency signals alone. Alternatively, a delay may be given for the delaying to only one of two local beam components which are coupled to two signal beam components for use in producing the two intermediate frequency signals.
