!*******************************************************************************
!
!! IVREAD is the main program for converting a graphics file.
!
!
! Introduction:
!
! This program was written for the Studio for Creative Inquiry.
!
! This program was originally intended to read an Inventor 3D graphics
! file, and write a corresponding VLA graphics file.
!
! However, it can also try to read files of several different types,
! convert the data internally to line data, and write out files
! of various types.
!
! DXF and Inventor file formats are sophisticated and extensive.
! This program was only designed to work on a few simple cases, and
! may easily be confused by unexpected (though legal) data.
!
! A sketch of the file formats and data structures is included
! in most of the READ and WRITE routines.
!
! The sizes of COR3_MAX, FACE_MAX and LINE_MAX control how much
! information this program can handle.
!
! The "head.25.iv" file has 240146 faces and 119,736 points.
! The "fish.iv" file has about 76000 faces.
! The "brain.iv" file has between 40000 and 75000 faces.
!
! Development:
!
! 26 May 1999: Added LINE_PRUNE switch, which will try to cut down
! (by about half) the number of superfluous lines created when
! faces are turned into lines by FACE_TO_LINE for VLA_WRITE output.
!
! 22 May 1999: For VLA output files, the program now will automatically
! try to temporarily convert all face information to line information. No
! sophisticated attempt is made to delete superfluous lines (the
! way FACE_TO_EDGE tries.)
!
! The "<<" merge command:
!
! On 20 April 1999, the "<<" command was added, to allow data
! from two or more files to be merged. It works, on a simple example,
! for OBJ files. However, some tuning of OBJ_READ was necessary.
! Similar testing and tuning must be done to the other READ routines
! before they will work with this option.
! On 21 April 1999, the "<<" command worked on a simple example
! using two IV files as input. SMF_READ was also updated for the "<<"
! command, but not tested. ASE_READ, DXF_READ, HRC_READ,
! STLA_READ and VLA_READ may already be OK.
! On 22 April 1999, "<<" command works with ASE_READ, HRC_READ,
! SMF_READ and STLA_READ.
!
! The "MatrixTransform" field in IV_READ/IV_WRITE.
! I'm having problems because I am reading in an IV file that has
! a matrix transform that is not the identity. I just ignore it,
! and so my data is not rotated and scaled, when it should be.
! As a start toward addressing this issue, I have IV_WRITE
! writing out the current transform matrix. One problem with
! Inventor is that the transform matrix can be specified on
! every level, and the actual transform matrix that applies
! has to be deduced from where you are in the tree.
! Right now, all I've done is have IV_READ read the matrix,
! and IV_WRITE write it out. No concatenation is possible right now,
! but my kludgy code will at least apply ONE transformation matrix
! to the data, in IV_READ, anyway...
!
! Adding material/normal/texture binding stubs, because
! A) new SMF format allows it;
! B) Inventor uses it;
! C) SCI wants to do textures eventually.
!
! SMF_READ and SMF_WRITE can now read and write face and vertex colors
! of SMF2.0 files.

!*******************************************************************************
!
!! ANGLE_RAD_3D returns the angle in radians between two vectors in 3D.
!
!
! Discussion:
!
! The routine always computes the SMALLER of the two angles between
! two vectors. Thus, if the vectors make an (exterior) angle of
! 1.5 radians, the (interior) angle of 0.5 radians will be reported.
!
! Formula:
!
! X dot Y = Norm(X) * Norm(Y) * Cos ( Angle(X,Y) )

! Parameters:
!
! Input, real X1, Y1, Z1, X2, Y2, Z2, X3, Y3, Z3, are three points
! which define the vectors. The vectors are:
! ( X1-X2, Y1-Y2, Z1-Z2 ) and ( X3-X2, Y3-Y2, Z3-Z2 ).
!
! Output, real ANGLE_RAD_3D, the angle between the two vectors, in radians.
! This value will always be between 0 and PI. If either vector has
! zero length, then the angle is returned as zero.

!*******************************************************************************
!
!! ASE_READ reads graphics information from an ASE file.
!
!
! Problems:
!
! Processing of the MESH_FACELIST assumes faces are always triangles
! or quadrilaterals.
!
! Discussion:
!
! It is intended that the information read from the file can
! either start a whole new graphics object, or simply be added
! to a current graphics object via the '<<' command.
!
! This is controlled by whether the input values have been zeroed
! out or not. This routine simply tacks on the information it
! finds to the current graphics object.
