Topic: Uh... new topic...

I guess at some point I should start a new train of thought...

OK.

This version of LaserBoy.... did you get that?

We're talking about LaserBoy here! ...

Ya' know!

Oh have you never heard of it?

.

Well let me tell you about it...

.
.
.

.
This version has a per channel (signal) polarity matrix switch!!!

My next big adventure is reading "Ambiguous Waves" of "Unknown Origin" !!!

 It looks like your global polarity works as before- are these new discrete polarity bits in the same 32bit word after the date stamp??

[James]

No. That 32-bit word is nothing but 32 Boolean flags that indicate the presence (or absence) of chunks of LaserBoy information in the header.

So far, it looks like this:

Code: [Select]

#define    EZ_WAVE_NO_MODE                0
#define    EZ_WAVE_POSITIVE               1
#define    EZ_WAVE_END_OF_FRAME           2
#define    EZ_WAVE_UNIQUE_FRAME           4
#define    EZ_WAVE_UNIQUE_POINT           8
#define    EZ_WAVE_OFFSETS                16
#define    EZ_WAVE_OPTIMIZED              32
#define    EZ_WAVE_SIGNAL_MATRIX          64
#define    EZ_SIGNAL_BIT_RESOLUTION       128

If the bit for EZ_WAVE_SIGNAL_MATRIX is set, then there will be a chunk of shorts (one for each channel) that will have some of the following signal ID tags in it. If the tag is positive, the signal is positive, if the tag is negative the signal is inverted!

Code: [Select]

  This opens up a can of worms... You aready have a master invert polarity toggle, together with discete polarity settings...
For example, say I render IN.ild, then I do a global inversion, next I do an individual polarity invert on X & Y. When I go back to see the data in LB or LW, the X-Y data should be absolute polarity due to double inversion (and the raw data is in fact correct), but that is not the case, because we both use the global invert toggle to view the data (without considering the individual channel may have already be inverted in the first place). In LW, the global polarity flip is applied only when Use Default Settings is enabled, which allows me to see what is really there when it's disabled. Gotta love that one!!!

[James]

Well... I knew I wouldn't do it right to suit YOU!  :

I think it makes some sense. It's one of those things. We'll have to actually work with it to see if it hold up to reason.

That's why the LaserBoy wave header additions has a version string!
