how to build 3D simulation of a model?

Hello,

I'm interested in building 3D model of quadrocopter in Matlab, but I have no idea how to build 3D model in matlab.

My goal is to express my dynamic model and thesis in a simulation model in matlab.

To get started you may want to build a CAD model of the quad and import it into simmechanics

i want to bulid a 3d design of a room in matlab how is it possible ?

Hi Martin,

With simulation of quadrucopter, you are perhaps interested in both quadrucopter model itself, and in surrounding scene in which it is supposed to operate.

With Quadrucopter, you can start with a simple representation (2 crossed beams, 4 cylinders, 1 box in the middle to represent batteries/ECU). This can be easily done using Simulink 3D Animation 3D World Editor. The Editor also provides several simple scenes (try "New from template" - Aerodrome_1) in which you can place your Quadrucopter.

Once you are satisfied with the behaviour of the dynamical quadrucopter model (Plant dynamics / Controller / control device input modelled in Simulink), you can replace a trivial Quadrucopter model with something more resembling a real aircraft - export the corresponding VRML model from a CAD tool and include (inline) it in your main scene.

Good luck,

Jan
