Tdpack - A set of routines allowing one to draw representations of three-dimensional objects.
TDPACK (which stands for "Three Dimensional PACKage") is a collection of routines for projecting objects from a 3-dimensional coordinate system having U, V, and W axes to a 2-dimensional projection plane having X and Y axes and/or for drawing the projections of those objects. This can be referred to somewhat loosely as "drawing objects in three dimensions". Tdpack consists of the following routines: Initialization Routines: TDINIT - Define eye position, line of sight, up direction, and stereo flag. TDPARA - Define the reference parallelogram. TDCLRS - Define colors for TDPACK. Parameter-Access Routines: TDGETI - Get the integer value of an internal parameter. TDGETR - Get the real value of an internal parameter. TDGTRS - Get the definition of a specified rendering style. TDSETI - Set the integer value of an internal parameter. TDSETR - Set the real value of an internal parameter. TDSTRS - Define a specified rendering style. Point-Transforming Routines: TDPRPT - Project from 3-space to the projection plane. TDPRPA - Project from 3-space to the plane of the reference parallelogram. TDPRPI - Project from the plane of the reference parallelogram to 3-space. Line-Drawing Routines: TDLINE - Draw the projection of a line in 3-space. TDLNPA - Draw the projection of a line in the plane of the reference parallelogram. Grid-Drawing Routines: TDGRDS - Draw the grids on all the faces of a box in 3-space. TDGRID - Draw the grid on a particular face of a box in 3-space. Label-Drawing Routines: TDLBLS - Draw labels for all faces of a box in 3-space. TDLBLA - Draw labels for a particular face of a box in 3-space. TDPLCH - Draw characters in the plane of the reference parallelogram. Surface-Drawing Routines: TDDTRI - Draw triangles defined by a triangle list. TDSTRI - Add triangles defining a simple surface to a triangle list. TDITRI - Add triangles defining an isosurface to a triangle list. TDMTRI - Add triangles defining a 3D marker to a triangle list. TDCTRI - Order the triangles in a triangle list for proper rendering. TDSORT - Cut triangles with a plane perpendicular to one of the axes. TDOTRI - Generic sorting routine

To use Tdpack, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably in that order.
When error conditions are detected, the support routine SETER is called. By default, SETER writes a message to the standard error file (as defined by I1MACH(4)) and then terminates execution. It is possible to put SETER into recovery mode and regain control after a recoverable error (which includes all of the possible errors). The possible error messages are listed below. All errors are recoverable in the sense that a user program which has called ENTSR to set recovery mode will get control back after one of these errors occurs.
