Geometry Compression

--- The Idea----

A plugin that seamlessly compresses Geometry (including things like, uvw tags and various other types of tags), thus reducung scene size on disk, and improving Network rendering Performance.

--- Benefits----

A: Small scene size on DISK
B: Faster Net Render or TR network Transport due to significanty reduced traffic
C: Faster Load and Save Times.

--- Basis ----

Already have a working plugin for Points and Polygons, which works, and depending on the data, files size that are at least, better than 1/4 the size of the original.

--- who needs this ----
Anyone dealing with large amounts of static geometry (polygon objects)




If your interested and want to support this idea, you can vote for it here..




thanks

Paul

isnt that what compression programs like zip or rar does?

The idea seems to be to do the compression/decompression within CINEMA 4D, thus reducing the amount of data transferred to or from disk/network.

Like the compression levels in alembic.

I'm assuming it would be easy to turn off the compression, if for example a client wants the scene file?

Regarding B, please check with Maxon on this, if i remember correctly TR already does compression for the network transfer, doing this again via plugin might result in far lower gain than expected.

Hi Paul
I say Yes, it will need for c4d and not only for it - for example, for vectorworks. it uses c4d as (rt-) renderer(renderworks)
Also i have question, why are start this project? i feel situation that was happen with cineman...maxon drop development of it, main developer left project... Will be Alembic-io project dropped?
And you have alternative solution

no. This is embedded compression. You load and save your file as normal. Its still a C4D file, but it just takes up a fraction of the space currently occupied.
Smaller file , faster loading, faster saving, faster network transport.

nothing, whatesoever, anything like the compression levels in alembic !

Absolutely, reversable and transferable. Hence the term "seamless"

I would purchase this. Count me in.

New features and better workflow are always welcome, but what kind of price tag are we talking of? 10, 30, 50, 100, 150 euros?

Sounds like a great idea- with each film I do have 1200-1500 large c4d project files so this would be a great space saver- I voted for it- thanks Paul!

some initial test results.


one object
18 million polys

saved as standard C4D scene = 721 MB
saved as crushed C4D scene = 148 MB (no load or save time hit)

standard C4D scene, post Zipped to 299 MB (takes 5 minutes to compress !)
crushed C4D scene, post zipped to 52 MB (takes 4 seconds to compress !)

unpacked = c4d scene without crusher
packed = c4d scene with crusher



So in this example (and some much bigger tests), I can conclude that crusher, can offer you a very strong compression rate over a standard scene save. Crusher offers an unheard of efficiency for 100% lossless, reversable geometry compression. When dealing with large amounts of geometry there is nothing else that comes even close, on any platform.


@bjorn : if TR is lwzipping the scene , the absolute best it could hope for is a reduction, as above, for "unpacked post".This will then probably spend more time packing and unpacking than it can save in traffic reduction/transport. Meaning, that for large geometry sets it is probably faster not have set compression in the first place with TR.
If TR is using network compression, the traffic reduction would be neglegable, to nothing, imo.
There is also Command line and NET and all the versions of c4d whch are not R15, that could make use of this, not discounting the archiving advantage of a 6/1 compression over the best that any zipper on this planet can do.


Also, if you look a the post zip results, and assuming TR is lzwing. When TR compression is activated, the absolute best thing anyone could do, who has huge amounts of geometry, is to Crush the scene. TR would then compress in seconds(as apposed to minutes), and only need to transport 1/6th of what it would otherwise have to transport.And the decompress takes a fraction of the time it would otherwise take on each client. Thats a pretty good combo imo.


regards
Paul
