FLuv32: increase dynamic range, and decrease precision.
...
This still exceeds the precision of LogLuv, but lets us match its
dynamic range.
2020-09-22 11:06:40 +09:00
9cf5ebdf91
Cleaning up the code in fluv32 a bit.
2020-09-21 11:54:14 +09:00
066105b20a
Fluv32: slightly tweak the u/v scaling constants.
...
This allows perfect representation of E (equal energy spectrum).
It's not important from a perceptual standpoint, but it provides
a simple way for Psychopath to represent E when needed for other
purposes.
2020-09-21 09:45:47 +09:00
05f9621ac5
Added a FloatLuv decode function to decode to Yuv instead of XYZ.
...
This is useful because it's super fast, and chromaticity lookups
are typical for spectral upsampling anyway, so this will likely
enable cutting out a bunch of unecessary intermediate calculations.
2020-09-20 15:16:20 +09:00
0ba1acc42d
Add oct32 encode_precise() function.
...
This is significantly slower than `encode()`, but a little more precise.
2020-09-20 14:36:50 +09:00
8c738b2f39
Use FloatLuv32 in Psychopath for encoding XYZ colors.
2020-09-20 11:04:37 +09:00

2020-09-20 10:37:26 +09:00
3eff608493
More FloatLuv32 optimizations, and general code cleanup.
...
This gives another little speed boost to decoding, but gives a
massive (over 3x) speed boost to encoding.
2020-09-20 10:07:02 +09:00
f4ef11f9f3
Fix some names in fluv32 error messages.

Additional optimization to fluv32 decoding.
...
Tiny change but with a nice speed bump.
2020-09-20 02:35:37 +09:00

Cleanup, tweaks, and better documentation for the 32-bit Luv format.
2020-09-19 23:57:59 +09:00
485da9f918
Add a new 32-bit Luv color format.
...
It's based on the SGI LogLuv format, but using a floating point
instead of log encoding for the luminance.

Make signed48 trifloat encoding also a byte array.
...
Same reason as for the unsigned40 encoding in an earlier commit.
2020-09-19 12:22:51 +09:00
49c97bf0fe
Cleaned up the signed48 trifloat code.
2020-09-19 08:55:35 +09:00
fd98b33333
Make unsigned40 trifloat encoding a byte array.
...
The whole point of these formats is to compress down to less
space, so let's not leave actually putting it in the space-saving
form on the client code.
2020-09-19 08:28:59 +09:00
9fb3c95171
Added an unsigned 40-bit trifloat format.
...
It is identical to the 32-bit format, except with more precision
and range due to using more bits. This format should comfortably
store any color information with precision easily exceeding the
limits of human vision.
2020-09-18 22:12:12 +09:00
96b8dd84b9
Cleaned up the u32 trifloat implementation.
...
This also makes encoding faster. However, it no longer does
rounding to the nearest precision when encoding, and insead does
flooring. This seems like a reasonable tradeoff: if you want more
precision... you should use a format with more precision.

f13ffac7bd
Removed the experimental luma-chroma color format.
...
It was a worthwhile experiment, but for it to really work it needs
a really proper luma-chroma separation, which is both slower than
I really want, and requires knowing the colorspace being used.
I might make another go at this based on the TIFF LogLUV color
format, requiring XYZ as input.
2020-09-18 17:57:13 +09:00
c1f516c2b6
Use a better chroma formula for the RGB32 format.
...
This makes much better use of the bit space.
2020-09-13 11:22:48 +09:00

Some code clean-up in the RGB32 encoding/decoding code.
2020-09-13 06:44:42 +09:00

More work on the packed HDR RGB 32-bit format.
...
Switched to a different chroma encoding, which is notably faster
and never produces negative values when decoded.
2020-09-11 21:57:43 +09:00
339568ec0c
Remove stale comments.
2020-09-10 22:42:20 +09:00

2020-05-01 16:08:37 +09:00
946a1860e0
Remove hierarchical instancing.
...
After thinking about this and after some discussion with other
people, I now believe that hierarchical instancing isn't actually
that useful in practice for rendering.
Single-level instancing is still supported, of course.
2020-05-01 16:08:37 +09:00
66dcbc2e7f
Re-implemented nicer error reporting.
...
We lost this in the initial move to streaming parsing. All
errors now (again) print out a line number and an error message.
2020-05-01 16:08:37 +09:00
46d0ef3b28
More parsing code cleanup and better error messages.
2020-05-01 16:08:37 +09:00

More parsing code cleanup and some better error messages.
...
Still more to do, but this is some decent progress.
2020-05-01 16:08:37 +09:00
c1f8d21814
Refactored data tree code to present a slightly nicer API.
2020-05-01 16:08:37 +09:00
6b188c4451
Parse errors now use Strings for error messages.
...
This allows the error messages to be more informative by including
dynamically determined information.
Also made a utility function for ensuring that nodes get closed.
2020-05-01 16:08:37 +09:00
4f564d1474
All parsing is now streaming! But lots left to do.
...
In particular, parsing error messages are now either terrible or
non-existent. But it compiles and works for correct inputs!

It's now the responsibility of the caller to feed the parser
data as needed.
