Strokes

Line Style: Strokes

By default all retrieved lines from the line set are chained together. There are two basic chaining methods:

Plain

The default chaining method; it creates simple chains.

Sketchy

This chaining option allows for generating chains of feature edges with sketchy multiple strokes. Basically, it generates Round strokes instead of a single one. It is only really useful if you use some random-driven modifiers in the line style!

Rounds

It specifies the number of rounds in sketchy strokes.

Chaining can also be turned off to render each line separately, which can be useful for line styles which depend on accurate representation of the line set.

Splitting

You can split up chains of Freestyle lines by checking one of the following:

Min, Max 2D Angle

Splits chains of feature edges when they make a 2D angle above (or below) a minimum (or maximum) threshold.

2D Length

Splits chains when they are longer than the given value.

Material Boundary

Splits chains of feature edges if they cross from one material to another.

Split Dash, Gap

Splits the chains using the given dashed pattern (“D” stands for “dash”, “G” stands for “gap”; see also Dashed Line).

You can sort the order of your strokes, allowing the lines to stack in the order given.

Sort key

A sort key is used to determine the stacking order of lines.

• Distance from camera

  Lines closer to the camera lie on top of further lines.

  2D length

  Longer lines lie on top of shorter lines.

  Projected X, Y

  Sort by the projected X or Y value in the image coordinate system.

Integration Type

Use in tandem with the Sort Key to determine the range for sorting. Since the distance of a line from the camera may vary over vertices, this option computes the sort key for a line from the values computed at individual vertices. The value computed for the line is:

• Mean

  The mean of the values obtained for the vertices.

  Min

  The minimum of the values obtained for the vertices.

  Max

  The maximum of the values obtained for the vertices.

  First

  The value obtained for the first vertex.

  The value obtained for the last vertex.

Sort Order

With the given result you can choose to “Reverse” the sort order.

Selection

You can also choose to only render selected chains.

Minimal, Maximal 2D Length

Chains longer and/or shorter than 2D Length.

Chain Count

Allows the selection of first N chains.

You can choose between three types of line caps:

Butt

Flat cap, exactly at the point the line ends.

Round

A half circle centered on the end point of the line.

Square

A square centered on the end point of the line (hence, like the circle, the drawn end of the line is slightly extended compared to its computed value).

Line caps example.

Dashed Line

By enabling the Dashed Line checkbox, you can specify three pairs of dash and gap lengths. Dash values define the lengths of dash strokes, while gap values specify intervals between two dashes.

If a zero gap is specified, then the corresponding dash is ignored even if it has a non-zero value.
