My name is Margaret Hu, I am a student at Ohlone College Fremnt California,
I am interested in the project "Geometry Conversion Library"
For the three requirement for this project
* Familiar with C/C++ : YES
* Familiar with file parsing issue (lex/yacc a plus) : YES, I know
flex/bison and regex
* Basic understanding of geometry information (will be needed for
understanding conversion issue) : Not sure here, perhaps it involves some
x,y,z coordinates? Not familiar with the various file format. I took a look
at the src/conv directory, the biggest file is obj-g.c with 3971 lines of
code.
I believe the idea is, assume we have File_Format_A (FFA) File_Format_B,
... etc. we need to first convert it into an Internal_Data_Structure that
can represent all the information we need to do CAD, later we can either
use this data structure directly or dump it into any file format.
typedef enum {FFA, FFB, ...} Format_t;
/*for input: */
Internal_Data_Structure *root;
switch () {
FFA:
root = parse("file.ffa", FFA);
break;
FFB:
root = parse("file.ffb", FFB);
break;
default:
}
/*for output: */
int status;
switch () {
FFA:
status = dump(root, FFA);
break;
FFB:
root = dump(root, FFB);
break;
default:
}
