bCAD 2.0 per DOS e Windows 95 / NT

Seconda Parte

di Andrea Lamberto

Caratteristiche principali

  • L'installazione minima di bCAD richiede 1 Mb di spazio libero SOLO per il file bcad.exe, che include all'interno tutti gli elementi necessari come un manuale, un help in linea, icone, fonts del sistema, almeno un font per disegnare, librerie di patterns e tipi di linea, un set di texture di materiali. L'unica cos da ricordarsi prima d'iniziare e di avere un mouse driver residente, dato che bCAD funziona quasi esclusivamente solo con il mouse.
  • Nella versione dimostrativa ci sono delle piccole limitazioni, quali la possibilita` di salvare progetti con al massimo 128 oggetti e la risoluzione limitata a 512x512 pixel per il Ray-Tracing (mentre per il Phong, il Gouraud e il Flat Shading si puo` andare anche a 1280x1024 !), che hanno potuto far si` che il programma potesse essere valutato in tutti i suoi particolari.
    Elementi base:
  • 32-bit native code, including Pentium optimised..
  • Standard multiwindow icon-driven GUI ( even withind DOS version )
  • Videosystem type autodetection/VESA support, HighColour and TrueColour
  • videomodes support, resolution up to 1024x1280
    • Built-in universal printer/plotter drivers, families of the devices which are supported:
    • HP LaserJet ( I, II, III, IV),
    • HP DeskJet ( including colour ones),
    • HP PaintJet,
    • HPGL compatible plotters
    • Houston Instruments plotters
    • Epson, Epson Esc/P2 series
    • All together over 180 devices are supported.
  • Virtual memory manager
  • Mouse/track-ball/pen/digitizer pointing devices support
  • Unlimited number of the drawings loaded simultainesly.
  • Unlimited number of the viewports opened for individual drawing.
  • Unlimited UNDO levels for each loaded drawing.
  • Unlimited number of the layers
  • Compressed 3D data format
  • Built-in Font editor ( BCAD's own format and AutoCAD SHP are supported)
  • Compatibility with AutoCAD line styles, hatch patterns and SHP fonts libraries.
  • Import of ready-to-render models from 3D Studio native format files including smoothing groups, material settings, textures, bumps and reflection mapping.
  • Export/Import 3D meshes to/from Autodesk 3D Studio ASC, Sense 8 NFF
  • Export raster images to BMP,TIFF,GIF,PCX,JPEG
  • Export vector drawings to HPGL,EPS
  • Import Textures from BMP/GIF/JPEG/TGA/CEL/PIC files.
  • AutoCAD R10,11,12 DXF Export/Import
  • Built-in Refernce Guide, context-sensitive help system, instant ToolTips, BalloonHelp facility
  • Simplicity in use and maintaining, all stuff is built into the single executable file ( 900K size )
