I have a large amount of point and point vector data, and now I want to use small balls to represent points and arrows to represent vectors. What should I do？ |

You'll want to use geometry instancing, the vsg::Builder class can be used with geometry instancing, have a look at the vsgbuilder example, when you run it with -n it'll create instances of each type of geometry shape. vsgbuilder -n 100000
The new vsgXchange::gltf loader also supports geometry instancing. The new vsgXchange::Tiles3D loader uses it when handling .i3dm instanced files. |
