Curve parameters


Some parameters are common to all curves, and others are specific to each type of curve.

To adjust a curve's parameters:
  1. Select the curve.
  2. In the Parameter Editor, adjust the parameters, then click the curve geometry to adjust the remaining parameters.

Common Curve parameters

Position

Object location in x, y, z coordinates

Orientation

Object rotation values in x, y, z degrees

Scale

Object scaling values in x, y, z multiplication factors.

Visible

Toggles object visibility.

Anti-aliasing

Turns on anti-aliasing to removes the "jaggies" on diagonal lines by blurring the curve. To see the anti-aliasing, it must be on for the object and the viewport. To turn it on for the viewport, right-click the viewport and choose Anti-aliasing. Anti-aliasing slows down the refresh rate.

Number of Points

The number of points that define the curve. When the curve is published in a web page, the points are downloaded and the AXEL player redraws the curve on the surfer's web page. Increasing the number of points increases download time.

Streamable

Makes the curve streamable so that a surfer can open a page and view the World without this curve. The curve appears when all its information is dowloaded.

Steps

Adds steps between vertices to make the curve smoother without adding points. See Modifying Curves.

Point positions

The X, Y, Z coordinates of each point.

Rectangle- and Square-Specific Parameters

Frozen

Hides the curve geometry parameters.

A curve freezes if you add, move, or delete points, subdivide or simplify it.

When the curve is frozen, AXEL draws the curve based on its points, not its width and height parameters. If you turn off Frozen, the curve is redrawn based on its width and height, and any points you modified move back to their original position.

Width

Size in units along the X axis.

Height

Size in units along the Y axis.

Circle- and Arc-Specific Parameters

Closed

Draws a segment between the end points to join them together.

Frozen

Hides the curve geometry parameters.

A curve freezes if you add, move, or delete points, subdivide or simplify it.

When the curve is frozen, AXEL draws the curve based on its points, not its radius parameter. If you turn off Frozen, the curve is redrawn based on its radius, and any points you modified move back to their original position.

Radius

Size in units.

Subdivisions

Adds points to the circle.

Angle

Determines the angle of the arc. A circle has an angle of 360 degrees.

Draw Curve-Specific Parameters

Closed

Joins the first and last point in a curve to create a closed shape.
