Primitives

Overview of Figment3D Primitives

This shape wheel illustration demonstrates each of the seventeen Figment3D Primitives. 

Starting counter-clockwise from top, these primitives are:  Tube, Torus, Washer, Frame, Box, Plane, Disc, Sphere, Cone, Tetrahedron, Pyramid, Cube, Cylinder, Hollow Cone, Dome, Arc90 and Arc180.

The first eight types use only the Spine and Slice curves:

  • Tube (Line, Circle)
  • Torus (Circle, Small Circle (half sized))
  • Washer (Circle, Small Square (half sized))
  • Frame (Square, Square)
  • Box (Line, Square)
  • Plane (Line, Line)
  • Arc90 (Quarter Circle, Circle)
  • Arc180 (Half Circle, Circle)

The next nine types also use the Lathe curve:

  • Disc (Line, Line, Half Circle)
  • Sphere (Line, Circle, Half Circle)
  • Cone (Line, Circle, Half Triangle)
  • Tetrahedron (Line, Triangle, Half Triangle)
  • Pyramid (Line, Square, Half Triangle)
  • Cube (Line, Square, Half Square)
  • Cylinder (Line, Circle, Half Square)
  • Hollow Cone (Vertical Line, Circle, Diagonal Line)
  • Crater/Dome (Vertical Line, Circle, Quarter Circle)

Finally there is the “empty” primitive:

  • None (None, None, None)

See examples and additional details below.

Curve-Based Primitive Examples

Two-Curve Examples:  Only the Spine and Slice keys are needed to make non-tapered surfaces.  Two-curve examples include:  Cylinder, Frame, Plane, Torus.  Other two-curve primitives are:  Arc90, Arc180, Box, Tube, and Washer.

Cylinder (Line, Circle)
Frame (Square, Square)
Plane (Line, Line)
Torus (Circle, Circle)

Three-Curve Examples:  Spine, Slice and Lathe keys are used to taper the radius of other Primitives.  Three-curve examples include:  Cone, Cube, Pyramid and Sphere.  Additional primitives (not shown) include:  Disc, Dome, Hollow Cone, Tetrahedron.

Cone (Line, Circle, Triangle)
Cone (Line, Circle, Triangle)
Cube (Line, Square, Square)
Pyramid (Line, Square, Triangle)
Sphere (Line, Circle, Circle)
