   Classconcept, big box with a lot of small boxes
  Hello Forum,i'm new in managed directx and got a basic question, i hopeyou can help me.I've got a big container (only 6 walls) in a 3D room.This container holds a lot of small boxes, calledcubes. The User can move these boxes via drag'n'drop.I'm working with C#, winforms, mdx 9.0c.My question is, how to organize my classes and how tocreate simple boxes. The performance is very important,because the 3D-View runs in a panel in a mdi-child-form.Currently the cube itselfs contains VertexBuffer, but closing the form takes a lot of time. The closing-time seems to increment every time i'm moving a cube.I draw them with SetStreamSource().Is it recommended to create the cubes with Mesh.Box() (but without *.x-Files) instead of VertexBuffer or what is the best way?I hope you can give me a hint.In germany we say something like "i can't see the forest, becauseof the trees" in my position.GreetzLena
