Vectors

The term vector graphics is typically used only for 2D (planar) graphics objects, in order to distinguish them from 2D raster graphics, which are also very common. 3D graphics as commonly implemented today (e.g., in OpenGL) are typically described using primitives like 3D ... points and polygons connecting these (which in turn describe surfaces); these 3D primitives are much more similar to vector graphics than to raster graphics, but aren't explicitly called vector graphics. The equivalent of raster graphics in the 3D world are voxel-based graphics. — en.wikipedia.org
