The National Shipbuilding Research Program. Proceedings of the REAPS Technical Symposium. Paper No. 10: Steerbear 3 With Interactive Graphics
Abstract
The development of the next generation of STEERBEAR (SB 3) is underway. The efforts are concentrated on general basic software adapted to interactive graphics and suited to a variety of applications and in particular to a new STEERBEAR HULL system (SBH 3). The main new features of SBH 3 will be: Interactive graphics available where feasible; Improved facilities for generation and handling of three-dimensional curves and surfaces; Parametric design modules covering more complex elements than in SBH 2; Improved facilities to create and use a 'product description'; Distribution of the computer work between main frames, mini- and microcomputers. A system work station is composed of a Digital Equipment microcomputer, a Tekronix storage tube with refresh capability, an alphanumeric screen and a graphic tablet. Basic graphic software has been developed and is operational on the work station. Within a few months the system work station will be used to present graphic output from SBH 2. The computers used are a PDP 11/34 and an IBM main frame. During the first quarter of 1981 a system for interactive working drawing composition will be in operation connected to SBH 2. Text and drawings generated by the current structure generation system can be combined and supplemented at the work station and then be returned to the main frame for further processing. The total development program of SBH 3 including basis interactive fairing and interactive nesting will be finished before the end of 1982.
