[SOLVED] How to move objects with keyboard and mouse?

[Weng]

Hi, everyone

In my simulation, I need to control surgical tools. Previously, I had a Phantom Omni device. But now, I do not have.
I have to use keyboard and mouse to control the tools.
Is there anyone did similar things before?
Any suggestion ?

regards,

Hi Weng,

You can indeed use the keyboard/mouse to interact with your simulation. Two possibilities:

• either you implement everything in C++. Based on the events in SOFA, you can detect when you press or release a key, press or release the mouse. To know hot to do it, please refer to the documentation.
• or you can use python. This way, you can interactively add new nodes, new components on events.

Let mw know if this isn’t clear or if you need some examples of these.
Cheers,

Dear Hugo,

Your reply does help.

Also, I found a component called MechanicalStateController in project SofaUserInteraction quite suitable for my purpose. And some examples in Controller folder are very useful.

In Qt GUI, to use mouse or keyboard, ‘Ctrl’ need to be pressed at the same time. Otherwise, the interaction defined by Qt viewer will be called.
