Bezier Curve

A Bezier curve in 3D modeling is a smooth parametric curve controlled by points and handles. Artists use it to define paths, outlines, profiles, and motion curves.

A Bezier curve blends its control points according to mathematical weights. Moving the control points changes the curve shape without directly editing every point along the curve.

A standard Bezier curve passes through its first and last control points. The middle control points usually act as handles that pull the curve and define tangent direction rather than points the curve must cross.

A cubic Bezier curve is a Bezier curve with four control points. It is widely used because it gives artists two endpoint positions and two handle positions for intuitive smooth-curve control.

A spline is a broader class of smooth curves. A Bezier curve is one specific spline type, and longer artist-facing splines are often built by joining multiple Bezier segments.

Bezier handles are control points or tangent controls that set the direction and strength of the curve as it leaves or approaches an anchor point. They are the main interactive tool for shaping a Bezier curve.

Yes. A Bezier curve can be converted or tessellated into mesh geometry, often after adding bevel depth, extrusion, or a surface operation.

Bezier curves are used in vector illustration, font design, user interface drawing, motion graphics, and animation timing. They are a standard way to describe smooth, editable shapes.

Bezier curves let artists create smooth, controllable forms with few editable controls. They are useful for clean silhouettes, repeatable profiles, precise paths, and smooth animation transitions.
