We are going to ignore the function of display_threeD_screen_initialize in the get_cooordinate_on_screen because it can create Screen parameter also.
So we could create the three functions also like the below for printing models, considered the function of display_threeD_screen_initialize.
// 20210306
int convert_model_lines( vLine **lines, vLine **line_2D, int *line_index, int max_num ) ;
int create_model_lines( vLine **lines, int *line_index, int max_num ) ;
int create_curve_lines ( int num ) ;
(20210307)
convert_model_lines can not return (vLine*) or can not memorize array.
1st, we think, array can not keep in sub-lootin but its message is like the below.
int convert_model_lines( vLine **lines, vLine **lines_2D, int *line_index, int max_num ) ends. *line_index = 0

For memorization in sub-lootin, we changed the literatures ovbious like the below, however, we can not set the &line_index in sub-lootin.
*line_index++ -> ++(*line_index)
We might think, we have to set the parameter alternative like the below.
int b = convert_model_lines( lines, lines_2D, &line_index, 4 );
|
-> int b = convert_model_lines( lines, lines_2D, line_index, 4, &another_line_index );

After create_model_lines, they can increase line_index like the below.
And in the case of convert_model_lines, we failed that.

int create_model_lines( vLine **lines, int *line_index, int max_num ) ends. *line_index=43
line_index = 43 returned from create_model_lines.
