Project Macros for specific toolbar

To avoid having to write a plugin (a bit complex), and to offer a toolbar specific to a project, we use “macros”.
Some details here : Macros

Function, expressions, styles to construct Bezier curves

The idea: propose an expression to draw a Bezier curve dynamically from control points carried by a ‘linestring’.

Details here: Bezier

Expressions + style for altitude profile

The idea: propose an expression to dynamically draw an altitudinal profile.

Details here : Profil

Script for a tracking shot

Using the temporal controller, the idea is to follow a ‘camera’ path defined by a linestring geometry.

Details here: Travelling

Prepare a DEM for Blender, well aligned with a print layout

Or how to cut, rotate a raster according to the extent of a print layout, by extrapolating the extent of the map to the entire page, taking into account rotations.

here : layout

Virtual layers… for planting trees

Virtual layer - recursion - or how to replace the geometry generator with a piece of SQL code.

a little more here : forest

A dock for adjusting variables

Typograph

Enforce labelling, animate it !
