The Random points on lines algorithm supplements the existing "Random points along line" algorithm, and will prove to be more useful to the majority of users than the "original".
Features:
The points are distributed randomly over the lines based on "along the line" distance, meaning that the distribution of the points will be flat over the length of the line (each place on the feature has the same probability of being "hit").
The Random points along line, on the other hand, uses a line segment based approach, meaning that the density will depend on the segment length (short segments will have a higher point density than longer ones).
When an algorithm returns this flag, and after executing it in a model it doesn't set a
certain output which remaining model algorithms depend on, then these branches are
pruned back and don't get executed for the model run.
Allows for creation of algorithms which impact the overall model flow.
This algorithm filters features by their geometry type. Incoming
features will be directed to different outputs based on whether
they have a point, line or polygon geometry.
Allows for model creation which responds to different input
layer geometry types by applying different logic depending on the
input geometry type.
Takes an input layer, existing field and a new name for the field, and
outputs a new layer with the selected field renamed.
While this result could also be achieved with the Refactor Fields
algorithm, Refactor Fields isn't particularly model friendly. It
relies on a constant, fixed table structure, and can't adapt to
input tables with different field structures.
In constrast, this simple Rename Field algorithm adapts nicely for
model use, because it operates on a single field only and leaves
all the other fields untouched.
to take attributes from matching feature with largest area of overlap only
This allows for easy polygon->polygon joins, where you expect there to be
only a single matching feature and don't want to include features which
are just touching or have just tiny sliver polygon overlaps.

Offers the following benefits over the GRASS/SAGA versions:
- Full support for z/m values and handling curved geometries without loss
of curves
- Works with all native data types, no need for format transformation
- Supports dynamic (data defined, per feature) translate/scale/rotate parameters
- Allows transformation and scaling of both Z and M values (if present)
- Supports in-place edit mode
