Usage guide for Compositing with Carbon Basic
From left to right:
- Color controls - select the color and line thickness.
"solid", "Set Fill Color", "No Fill", and "Alt Fill" are disabled as this is not a closed figure.
- Direction - sets the initial direction of the vector away from the origin.
- Curvature - sets the amount of curvature, may be zero for a straight line.
- Radius / Circumference - for non-zero curvature determines if the size sets the radius or circumference.
When animating the curvature in radius mode the line will grow in a circular motion with a
constant radius. Conversely when in circumference mode the line will have a constant length,
increasing the curvature cause the radius to be reduced, tightening the circle.
- Shape - top button stretches vertically, bottom button shrinks vertically. Left button
shrinks horizontally, right button stretches horizontally. The center button sets the
height to the width for a symetrical shape.
Note: vertical and horizontal are referenced to the unrotated frame. Rotating the frame
rotates these axes, so at 90 degrees "vertical" becomes horizontal. Frame rotation is specified
in the "Blending" tab.
- Frame angle - the entire shape is rotated. First elongate one dimension with the shape
control (above) then rotate the shape - the elongation rotates.
- Alignment - designates the "hot spot" of the shape.
- Readouts - these display the 5 values used for drawing. Mostly used for debugging, but also
useful for duplicating another line.
- Size - controls the length/circumference/radius of the generated vector.
- Position - this controls the location of the other end of the line.
there are no mouse actions for vectors.
