Bchan Format Specs


Recommended Posts

Hi guys, I am still having trouble writing out a proper bchan file from an app that I'm writing.

Yes I know bchan may change in the future as a format and hence it's better to write to chan but .. I still want to write to bchan for it's compactness and also faster to load.

It's a bit frustrating trying to reverse engineer bchan and i'm close but no cigar. I loaded the .bchan

file in to vc++ and noticed a "chan" header. So I wrote that. Then included the interleaved data a.k.a

chan

float float float float...

float float foat float ...

so this seems to be ultra simple except houdini still does not see my .bchan file.

I just need the bchan format documentation, and if I had that I'd be set. Or if someone

can post an example.

As allways, thanks for the help!

Austin

I have the source but may not be able to get it to you until Monday, having just put in a 14 hour day Saturday and likely the same Sunday. It's on one of my old IRIX boxes at home plus I know the developer and will contact him should I have trouble finding it on my machines.

Mark THANK YOU!!! and I hope you got some rest!!!

This helps extremely, all the header code I need is right there. I havent yet tested the code yet as I'm not near my dev box but I'm sure it will all be fine.

Again, thanks very much for stepping forward and helping with this issue!

If you are local (Cali), I'll buy you a beer! or coffee :)

Out out curiosity - did you know that you could write out .chan files and feed them through chcp which I believe can convert from ASCII to binary format chans. I haven't tried it at all.

Yea, it's handy, especially for the *really* large channel files!

Hi Austin,

Glad it helped out.

I'm in NYC but will be in LA early next year and just might take you up on the offer! :P

Let me know if you run into any problems.
