Mesh data is SceneCity’s internal representation of a mesh. It contains the vertices, edges, faces, normals, UVs etc… Not to be confused with a Blender mesh.

A map is like a grayscale image, it has only one channel, no color. But unlike an image, it is not a raster, it is continuous. It may be based on a procedural noise function, or based on a raster image, or mixed.

A texture set is like a PBR material, it’s a collection of images, each one for a different channel in the PBR workflow (and other useful maps). Ultimately they are meant to be output as images and used in materials / shaders.

A collection of Blender objects.

Not to be confused with SC objects.

Paths are 3d polylines, they are a sequence of linked points, with a start point, and an end point. Unlike graphs, they cannot branch, meaning each point along the polyline can only have 2 links at most: one before, one after. A point cannot be disconnected, except if the path has only one point.

These are similar in concept to Blender’s bezier curves. They are in 3d.

A collection of the internal representation of objects in SceneCity. They can later be converted back to different types of Blender objects using specific nodes, for instance the objects instancer node.

A collection of buildings. A building is made of SC objects, and has a size in grid cells. Typically placed on a grid.

A collection of road portions. A road portion is made of SC objects, and has a type: straight, T-crossing, X-crossing… Typically placed on a grid.

A grid is a 2d array. And in each cell can be stored any number of key / value pairs. For more details about grids, check the grid node. Can be used for lots of things, but typically used to place buildings and road portions.

Combines a map, with a physical size on X, Y and Z, so that the map has a scale in the 3d world. The physical size on X and Y is the exact size of the terrain on both axes, whereas the Z value is simply an indicator of the intended height where the map is equal to 1. Z is multiplied by the map values, normally between 0 and 1, but they can be any value, so the terrain heights can go beyond the height given in Z, and below zero as well.

Generic 2d geometries: points, lines, polygons.
