Curve

Realsoft Graphics Oy		Curve
	Unified Creation Tools

With the Curve tool you can create freeform NURBS curves, trim curves, NURBS surfaces and extruded NURBS objects with freeform intersection, polygons, polyhedrons, polymids, and mesh map objects. The tool can also be used for 3D painting freeform curves to underlying objects that have bitmap textures.

The first option of the curve tool, Class, let's you choose what kind of objects to create.

Geometry - Creates an analytic polygon, polymid, polyhedron, or a NURBS curve or a NURBS mesh.

Type:

Analytic - create polygon, polyhedron or polymid
- Extrude - If set, creates extruded objects, i.e. polyhedrons and polymids.
- Depth - Depth of the extruded object.
- Freehand - If set, the polygon, polyhedron, or polymid is defined by moving the mouse while holding down the left mouse button.
Nurbs - create NURBS curve or mesh
- Extrude - If set, creates extruded objects.
- Filled - If set, creates a surface whose boundary is the defined freeform curve
- Order - order of the NURBS curve
  - Polygonal
  - Quadric
  - Cubic
- Interpolate - If set, the curve passes through the defined points. Available only when a Cubic curve is created.
- Freehand - If set, the curve is defined by moving the mouse while holding down the left mouse button.
- Closed - If set, defines a closed curve or surface.
- Pen - Create a NURBS surface using an existing, selected curve as a pen.
  - None - creates a curve, no surface.
  - Sweep - the selected 'pen' curve is swept along the curve drawn and rotated according to the curvature of the curve drawn.
  - Rail - the selected 'pen' curve is swept along the curve drawn. The pen object is not rotated while sweeping.
  - Rotate - the pen object is used as an axis and the new curve is rotated around it.

Map - Creates a mesh mapping.

Order - order of the NURBS curve
- Polygonal
- Quadric
- Cubic
Interpolate - If set, the curve passes through the defined points. Available only when a Cubic curve is created.
Freehand - If set, the curve is defined by moving the mouse while holding down the left mouse button.
Closed - If set, defines a closed curve or surface.
Class - class of the map created
- Material - Map a material
- Effect - Map a particle post effect
Effect Name - name of the material or particle post effect to be mapped

Trim Curve - Creates a trim curve. A NURBS mesh must be selected.

Order - order of the NURBS curve
- Polygonal
- Quadric
- Cubic
Interpolate - If set, the curve passes through the defined points. Available only when a Cubic curve is created.
Freehand - If set, the curve is defined by moving the mouse while holding down the left mouse button.
Closed - If set, defines a closed curve.

3D Paint - Paints curves to underlying objects that have bitmap textures.

Order - order of the NURBS curve
- Polygonal
- Quadric
- Cubic
Interpolate - If set, the curve passes through the defined points. Available only when a Cubic curve is created.
Freehand - If set, the curve is defined by moving the mouse while holding down the left mouse button.
Closed - If set, defines a closed curve.
Line Width - width of the curve to be painted.
Filled - Select either filled curve or non-filled.
Color - color of the curve to be painted.
