NAME
       ev - Evaluates the objects specified by tessellating all	primitive
       shapes in the objects and then performing any Boolean operations
       specified in the	objects. The result is then displayed in the MGED
       display according to specified options.

SYNOPSIS
       ev [-dfnrstuvwST] [-P #]	[-C #/#/#] {objects} []

DESCRIPTION
       Evaluates the objects specified by tessellating all primitive shapes in
       the objects and then performing any Boolean operations specified	in
       them. The result	is then	displayed in the MGED display according	to
       specified options.

       o    d--Do not perform Boolean operations or any	checking; simply
	   convert shapes to polygons and draw them. Useful for	visualizing
	   BOT and polysolid primitives.

       o    f--Fast path for quickly visualizing polysolid primitives.

       o    w--Draw wireframes (rather than polygons).

       o    n--Draw surface normals as little Ahairs.A

       o    s--Draw shape lines	only (no dot-dash for subtract and intersect).

       o    t--Perform CSG-to-tNURBS conversion	(still under development).

       o    v--Shade using per-vertex normals, when present.

       o    u--Draw NMG	edgeuses (for debugging).

       o    S--Draw tNURBs with	trimming curves	only, no surfaces.

       o    T--Do not triangulate after	evaluating the Boolean (may produce
	   unexpected results if not used with the w option).

       o    P#--Use # processors in parallel. Default=1.

       o    r--Draw all	objects	in red.	Useful for examining objects colored
	   black.

       o    C#/#/#--Draw all objects in	the specified rgb color.

EXAMPLES
       The first example shows the use of the ev command to display two
       evaluated objects as shaded polygons. The second	example	shows the use
       of the ev command to display an evaluated object	as wireframe without
       triangulating.

       Example 1. Display evaluated objects as polygons.

       mged> ev	region1	shapea
	   Displays evaluated region1 and shapea as shaded polygons.

       Example 2. Display an evaluated object as wireframe without
       triangulation.

       mged> ev	-wT region1

       Displays	an evaluated object, region1, as wireframe without
       triangulation.
