Hi, Sorry if multiple postings appear- Netscape on college meachine is
screwed..
Spec :(Topic Ideas) - In no particular order.
Cordinate Model
Poloygon Model
Clipping, Winding
Color Model
L-Draw Langauge
Drawing commands
Meta commands
File formats.
Standrad Parts & Primitives.
Element numbering Scheme/ Parts Categrisation.
Parts
Sets
The following could be working groups in the (VRML consortia sense).
Electrical- Tracing of power-electrical items.
Lighting- Sound.
Animation- Animating models produced by DAT's
- movment-motion systems.
Plugin - Development of a standrad plugin Architecture
for L-Draw
related progs.
Geometries - How to have "joints" systems.
- Additonaly there is the 'hinge' problem
in steped instructions!
-
Track Layout - How to model lego trains and roadsystems.
-(Simmilar to Loco & Matts Track Designer)
Would also look into having plan views for
Models.
Registry- A standardised scheme for incoperating new parts.
Distribution- How to modify system for coperative working
(VRML?)
Render - Raytracing?
Decesions reached by the working groups would after consultation become
part of the specification.(and used to devlop a new program...)
Feel free to suggest ommissions or additions.
I am prepared to put in a little effort if needed, but college work must
come first!
It would be an aim of producing the spec. to then use it to write a
program which could be used for Lego(R) CAD purposes.
Ideas for any new version (compiled from reading lugnet.cad.dev):.
UNIX/Windows/Mac versions.
CAD Engine seperate :
Suppourting 24 Bit Color - & Alpha?
Using all modern Computer Graphics techniques for
speed.
(ie clips,back face culling etc)
Ideally built on top of OpenGL(Mesa).
Suppourts limited curves.
Face-Texture Mapping for artwork ( using PNG not GIF?)
(NB Sometimes easier to do artwork flat!)
Suite of programs to do.
All supourting ideas outline above.
Parts Libaray:-?
Replace current scheme with object repositry(parts bin).
-Simmilar to componet bar in Delphi.
Model Builder - Builds Models !-
Use parts bin
In 3D ? -2D
BOM- Parts List
Instruction Generation
Layout(Terrain) Designer - Build Layout of models produced
above.-
(eg Trains-Roads)
- Can build
routes-and landscape in which
to place models.
Train Builder-? For building up trains of Vehicles-.
Minfig Modeller -
Piece-Editor - Visual - using Studs as grid?
