To provide a building renovation supporting apparatus capable of drafting and presenting efficient renovation plan, the proposing means 51 creates the renovation blueprints composed of third dimensional path diagrams of particular view-point, line of sight direction and the view angle corresponding to each types of condition of the symbol diagram to be inputted from the inputting means 10 with many view-point information, visual lien direction information and the view angle information necessary for drafting the third dimensional path diagrams being corresponding to various types of condition of one type of symbol diagrams such as position, direction, angle or the like respectively.

Computer aided building renovation supporting systems

The present invention provides a simulator which is easy to manipulate, and with which a user can experience a realistic simulation in various 3-D spaces, or a designer can understand physical environment conditions with the spaces intuitively or analyze mutual affects when there are a plurality of people in the spaces. The simulator comprises an input manipulation unit that the user can manipulate with one hand, a soft-robot display unit for displaying a soft-robot in accordance with the physical environment conditions, and a soft-robots display unit for producing a plurality of soft-robots.

Simulator for producing various living environments mainly for visual

The present invention discloses a sound environment simulator including a sound field analyzing unit, a sound field reproducing unit, and an output unit. The sound environment analyzing unit divides the solid surfaces of a space to be analyzed into a set of sections to compute the volume of reflected sounds with a sound absorption coefficient of walls and form factors. It further computes time series data related to the arrival volume of sounds emanated from a certain sound source to the sound receiving point. An impulse response computing unit in the sound field reproducing unit transduces the time series data into an impulse response. Accordingly, the sound field reproducing unit convolutes the impulse response on a dry source in accordance with data related to a listener's position inputted from an associated virtual reality equipment to generate a reproduced sound over a headphone.
