Make object visible only for a set of vision sensors

[minisch]

Hi,

I would like to know if is it possible to make an object visible only for a set of cameras and for all of them or only for one of them.

Thanks in advance.

Hello,

you have several possibilities, but this depends on whether you are talking about cameras, or vision sensors.

First, you can set a property for each object in the object common properties: Can be seen by

Then, for vision sensors, you also need to have the object flagged as renderable (in the same dialog). Finally, you can specify in the vision sensor properties Entity to detect: there, you can specify a single object, or a collection, that might contain several objects (and that can be dynamically modified).

Cheers

Thanks a lot for the quick reply. I thought I was subscribed to this topic but I wasn't probably.

I will try what you said and see if it works.

Anyway I am working with vision sensors.

It works smoothly thanks.

I can add just one thing. To create a collection, you should select your objects you want to include in the collection and then:
Tools-->Collection

and you create the collection you want.

Once the collection is created is like an object and you can go in the properties of your vision sensor and select the collection you want to look at.

Thanks again

Hello,

I would like to ask for an update for this problem solution, when in version 4.3 there is no "Entity to detect". My old vision sensors from previous version still hold the settings, so I expect it will be script code based?

Thank you

Entity to detect can be set via Lua code:

sim.setObjectInt32Param(sensorHandle,sim.proxintparam_entity_to_detect,entityHandle)

Entity to detect can be set via Lua code:

sim.setObjectInt32Param(sensorHandle,sim.proxintparam_entity_to_detect,entityHandle)

Thank you for quick reply, for vision sensor I found better parameter: sim.visionintparam_entity_to_render

You are right, I confused the two params :)
