ben-scans/solidify/array.h
Werner Almesberger cef7cd5e18 Added interactive 2D transformation (working towards overlapping)
- solidify/Makefile (OBJS): added overlap.o
- solidify/Makefile (CFLAGS): added -O9 to speed up rotation a little
- solidify/array.h, solidify/array.c (get_bounded): like get(), but returns
  UNDEF if the indices are outside the array
- solidify/face.h (struct face, struct matrix), solidify/face.c (read_file):
  added a 2D transformation matrix to "struct face"
- solidify/overlap.h, solidify/overlap.c: show a face with 2D transformation
