3D Generator

3D Generator  -  The 3d generator of a 3D Layer represents a source of geometry.

The 3D Generators are at the core of 3D Layer : they define the raw geometry on which modifiers and renderers will operate. It can either be a 3D primitive generated by Smode, a particle system, an external 3D file or a vectorial spline in SVG format.

Smode deals with three types of information in geometries: points, lines and triangles. Depending on which information a geometry contains, some renderers may or may not work.

• A particles system is a geometry that contains points only and that can be rendered with Sprite Points .
• Splines contain both points and lines, which makes them renderable with Points Renderers and Line Renderers.
• Meshes contain the three types of information, which means that they can be displayed with all available renderers.

The following image illustrates the Geosphere generator displayed with one renderer of each type:

Particles have a dedicated topic but is still a 3d generator with point informations.
