I am looking to develop a 3d object environment that allows me

to place objects in the world and animate them over time. I know

there are third party 3d environments like Unity that I can integrate

with Max, but I would rather not have that dependency.

1. ability to add objects to the world: (sound sources, camera views, etc.)

2. specify geometry of the room I am performing in

3. ability to set object properties (similar to the object inspector)

4. ability to move animate objects over time

The main purpose of the application would be to do spatialization of sound

I am a pretty seasoned programmer and I would prefer to do any custom

work in C++. That said, it would probably take a lot of work to create

a custom external that does all the above. Jitter already has a lot of

support for displaying 3d stuff. So all I might need to do is do some

So I would be open to any advice in devising a plan to create this

3D object environment. What existing components could I leverage and

what custom objects would I need to create?

i am very interested :) i don't know a thing about jitter, would recommend using opengl related stuff ? seems to be the thing about 3D.

For basics about what such a thing would give, maybe you know about this but just in case, there is this example patch in C74/examples/3rd_Party/OpenGL_Audiospatializer.

currently designing my own environment, I asked a bunch of question on the forums (I wrote a "bunch", really :p)

I guess it could help.


I used COSM for this purpose in the past: 

I hear the new jit.anim and jit.phys objects do a lot of that - and more - now too.

It helps to navigate but more more indeed.

I'm using it to drive my cam everywhere in my space :)

jit.anim, especially, is very strong.

@dtr, I have looked at COSM as well, although it does spacialization it

is not really very extendable and would make a pretty clumsy platform

@Julien, yes, I did see your posts. I believe we are working on something similar. But I believe you decided to take the JAVA route in implementing

your design, which I am not really interested in doing. I am much faster

As I see it there are some specific pieces that I need to implement in c++

that would glue things together. I will certainly study your posts I am

for adding objects that do other things.

So that leaves ability to set object properties. Is there

a way I can tie in to Max's object browser to have it display

Also, I will need to save all this data. How do I serialize

My requirements:
1. ability to add objects to the world: (sound sources, camera views, etc.)
jit.gl.render

2. specify geometry of the room I am performing in
jit.gridshape, and jit.gl.model

3. ability to set object properties (similar to the object inspector)
?

4. ability to move animate objects over time
jit.anim.drive and jit.phys

So that leaves ability to set object properties. Is there
a way I can tie in to Max's object browser to have it display
custom properties of my 3d objects?

Also, I will need to save all this data. How do I serialize
a heterogeneous mix of data?

With java or c, you have almost all answer to your questions in my threads :-) ( feel free to ask me some specific questions if you need it, I'll do my best to help you)

About properties and serialization.. Jesse pointed me to something in java, but I'm sure there is the same in C

But ... I wouldnt trust a global model like that, and actually I don't .

I made store and retrieve functions that read an XML files and it's attributes and leafs, and which can write too.

It has been done because I made previously an objects model with all my properties and features related to all my objects.

But basically, those functions are very basic.

"You create a class which extends MaxObject, as you would with any abstract class.

This class is the class you call via the mxj object in your patcher."

This would be a great way to do things. I can derive my objects

from an existing Max object and then add my custom stuff.

Actually this is definitely doable in c++. The question is

can I derive my object from an existing object like jit.glrenderer.

public class Foo extends MaxObject
{
...
}

Julien, how are you setting the properties of you sound objects?

Are you using the object inspector or some other display?
