Below is the list of primitives that are working/exported correctly, partially and not touched yet.
 
 
 
= Primitives that are working properly =
 
= Arbitrary convex polyhedra =
 
== ARB8 ==
 
This primitive is formed in POV-Ray using mesh.The mesh object can be used to efficiently store large numbers of triangles.
 
Example:
 
    mesh{triangle{a,b,c}triangle{a,c,d}triangle{a,d,f}
 
    triangle{g,h,c}triangle{e,f,g}triangle{e,g,h}}
 
 
 
== ARBN ==
 
An arbn record is specified by N sets of intersecting planes, each defined by four coefficients:
 
 
 
* the {X, Y, Z} coefficients of the plane's normal vector pointing outward from the center of the arbn shape, and
 
*the perpendicular distance of that plane from the origin.
 
Its exported in POV-Ray by using intersection of Planes.
 
Example:
 
    intersection{ plane{<x, y, z coefficients>, normal} .... }
 
 
 
 
 
= Ellipsoids =
 
== ELL ==
 
This primitive is named as spheroid in POV-Ray. It is having
 
Center Vector, Radius Vector
 
Example:
 
      Spheroid(<-1.50,3.00,-2.00>,<2.0,1.2,2.5> )
 
 
 
== ELLG, ELL1 ==
 
These primitives are exported under Ell
 
 
 
== EHY ==
 
Elliptical Hyperboloid of BRL-CAD can be formed by POV-Ray.
 
Currently its coordinates are exported successfully and is done by using quadric equartions of POV-Ray
 
 
 
== EPA ==
 
Elliptical Paraboloid in BRL-CAD. Its coordinates are exported successfully and is done by using quadric equartions of POV-Ray
 
 
 
== Sphere ==
 
Sphere is formed by
 
Center and Radius
 
Example:
 
      sphere { Center, Radius [OBJECT_MODIFIERS...]}
 
 
 
 
 
= Cones and Cylinders =
 
== Truncated General Cone ==
 
This primitive of BRL-CAD is formed by using Supercone of POV-Ray.
 
Example:
 
    Supercone( //point A, axis Ax, axis Az:<0.0,0.0,0.0>, 0.5, 1.0,
 
                // point B, axis Bx, axis Bz:<0.0,1.5,0.0>, 0.7, 0.4)}
 
 
 
== Cone ==
 
This primitive of BRL-CAD is named as Cone in POV-Ray. It is formed as
 
Center and radius of one end
 
Center and radius of other end
 
Example:
 
      cone {<0, 1, 0>, 0.3  <1, 2, 3>, 1.0 texture { T_Stone25 scale 4 }}
 
 
 
== TEC ==
 
Its also exported under TGC.
 
 
 
== REC ==
 
Its exported nuder TGC.
 
 
 
== TRC ==
 
Its also under TGC
 
 
 
== Cylender ==
 
This is formed by Cylender of POV-Ray.
 
center_of_one_end, center_of_other_end and Radius
 
Example:
 
      cylinder { <0, 1, 0>,<1, 2, 3>,0.5 }}
 
 
 
== RHC ==
 
Right Hyperbolic Cylinder in BRL-CAD. Coordinates are exported successfully. It can be formed by using function
 
      function { pow(x,2) + y }
 
of POV-Ray.
 
 
 
== RPC ==
 
Right Parabolic Cylinder in BRL-CAD. Coordinates are exported successfully. It also formed by the using functions of POV-Ray.
 
 
 
= Other Solids =
 
 
 
== Torus ==
 
Torus is created using
 
major radius and minor radius
 
Example:
 
    torus { 4, 1 pigment { Green }}
 
 
 
== Particle ==
 
This primitives of BRL-CAD is formed in POV-Ray by using Round_Cone2 of POV-Ray.
 
Example:
 
    Round_Cone2(
 
    //point A, radius A: <0,0,0>,0.70,
 
    // point B, radius B:<0,1,0>, 0.40,)
 
 
 
== half ==
 
Half primitive of BRL-CAD is export into POV-Ray as Plane.
 
Example:
 
      plane { <Normal>, Distance }
 
 
 
== BOT ==
 
Bag of triangles in BRL-CAD. Its exported by using triangles in POV-Ray.
 
 
 
 
 
= Primitives that are under progress =
 
== ETO ==
 
Elliptical torus of BRL-CAD can be formed by using some methods. One of them is by using function i.e. f_torus
 
Example:
 
      f_torus(x,y,z,1*(y+0.4),0.1 )
 
 
 
== extrude ==
 
Currently, data of extrude is exported successfully. Remaining part is how to export sketch and relate it with extrude.
 
 
 
= Primitives that are not under work yet =
 
 
 
== derived from 2d ==
