View Full Version : bezier help?

Looking for help on the Bezier modeler tool, it's not listed in the Contents section; clicking on "Bezier Curve" in the Index brings up "Gradient"; searching for "bezier" brings up non-modeling topics.

Is this an omission?

Some time ago we made Bezier polygon type, free plug-in. It can be downloaded from http://www.trueart.eu. Unlike LW Bezier it stays Bezier or B-Spline until you freeze it.

Not sure how it got left out of the LW9 docs but it's in the LW8 docs.

Here is what was in the LW8 docs:

The Bezier Tool

In addition to making polygons from points, you can also create curves from points. Curves are a powerful modeling tool and help you create smooth edges and flowing organic objects or object details. Curves are also used for some modeling tools as a directional path for some tools to follow.

You can create curves using a minimal number of points, yet achieve a smoothness that would take many times the number of points if you attempted to mimic the curve with a polygon. Moreover, with fewer points, it is easy to subtly or dramatically change the curve’s shape. However, by themselves, curves will never render in a finished image. Curves are essentially a free-form modeling tool used to create polygonal objects.

There are basically two types of curves: open and closed. An open curve has a beginning and an end—essentially a curving line. A closed curve has no beginning or end; it is a closed loop. A circle would be considered a closed curve.

The Bezier tool (Create > Curves: Bezier) allows you to create standard spline curves using tangent controls. If you’ve used any vector program you will feel right at home using the Bezier tool.
To use the Bezier tool:

1 - Choose Create > Curves: Bezier.

2 - Place your mouse pointer where you would like to begin your curve.

3 - Click and hold your LMB—the beginning and ending of your first curve is created. Drag your mouse to where you want the curve to end and release the mouse button.

4 - Successive clicks will create additional curves.

5 - Drag the tangent handles (circles) to adjust the curve shape. Holding the Ctrl key while dragging will allow you to move both sides of the tangent simultaneously.

6 - Click and drag with the LMB in the large circles that represent the curve control points to change the control point’s position.

7 - Drop the tool by hitting the Spacebar.

NOTE: Once you drop the Bezier tool, a normal Modeler curve is created. As such, you cannot re-edit the curve using the Bezier tool.

On the numeric panel, you can set the subdivision level (for smoother or less smooth curves), create a closed curve, and delete the last tangent point.

Thanks, Proton. That's what I was looking for. :thumbsup:

Thank you, too, Sensei. I'll be sure to check our your plug. :)

The bezier tool should be listed on pg 129 of the Modeler book.
