Real Time Auralization 1 Reply

Dear all, for those of you interested in real time auralization, I recently made this GH file to use the outputs from the Pachyderm image source tracer to send auralization data to Max-MSP and Spat-5…Continue

Hi Petros,

I just tested both of those systems, and they seem to be working fine (both openings of .pac1 files, and custom absorption coefficients). However, if you have found something I can't reproduce, the best thing you could do is send me the .pac1 file, so that I can look into it.

Regarding the absorption coefficients, try again. I'm very certain that system works fine.

Hi Surakist,

Sorry for the long wait. I didn't get a notice that you had posted... Happens sometimes.

First off, what pachyderm is doing is very computationally intensive, so unless the window outright disappears, it has not crashed. You should just wait for it to complete what it is doing.

Second, it is likely that you are using very low absorption coefficients. You should reconsider whether those coefficients are the right ones. There are few places on earth that have that much reverberation.

Let me know if you have additonal questions.

Hi Arthur thanks for your great plugin and hi everyone,

on "pachyderm hybrid models" window

-I am facing some problems on opening analysis data that was previously saved as a file type ".pac1" from pachyderm.

-Also, I find a problem at the material section,  when I assign a custom material on a layer, it will automatically reassign this material to all the project layers. So I am using the "object acoustic setting" at rhino properties to input the absorption material data.

I am running latest pachyderm on windows Rhino 6.

I am just wondering if this is something known or is me doing something wrong.

Best regards

Hi Authur

I am study in master degree and i am researching about Changing Acoustic in Multi functional space  

I have some issue about "Ray tracing" Component in grasshopper when i put all the value and then the Ray tracing will show a message "Preparing Threads" for long time and then clash and not responding and another case it can work but just some Ray that reached and then it clash again. I don't know why this component can not run. How solve this problem ? what should i do ?

ps. I use Minimum Convergence so Do i no need to put value in Number of Rays ?

 

Thank you

Hi Prakati,

Simple. Load Pachyderm for rhino before opening grasshopper. The grasshopper plugin depends on the rhino plugin to work.

To load it, just run any Pachyderm command in the command line

hey arthur im having issue with pulling the rhino geometry to polyscene . its showing this error please help

Hi Prakrati,

It sounds like your screen is a bit small. sorry about that. I'm afraid I don't have a good solution for you at this time.

Maybe you can find a larger screen somewhere. (I'll see how small I can allow it to get for a future release... I think there was a limit in terms of the legibility of the graphics, though).

hey arthur 

thanks for replying . i have one more doubt how to adjust the interface of the call absorption . i have already tried to adjust the screen resolution it doesn't fit . what to do ? 

thanks
