WebGL - TED DXML importer

So I redid some javascript; Now I have a stronger preliminary system for loading data from TED files. It's scary fast, and impressively so. (The GL part anyways)

So, make sure you export ONLY data in the TED format, not the JSON format. Use the TED format because it's a lot easier to read and understand, and it's not much less efficient than a JSON file (Maybe 1% tops).

You must export your own test model for now, from blender. Download the source here to try it on your local machine

TED Exporter (test 2.49b, not yet 2.5* compatible):
http://www.gocaco.com/webgl/igtl_export_ted.py

Download the python file, put it in your blender scripts directory (blender/.blender/scripts for me) or add it on to your 2.5 (not tested, API not stable)

Then open any file you want, and select some objects, then File->Export TED.
You may want to poke through the python a little to read something about what it does.
Save your exported ted file (All ted files are UTF-8 ASCII only, so always human readable) and place it wherever you extracted the source index.html.

Then, just enter in the name of the file and click load, nothing nothing breaks.

You should be able to fly around a (currently non-objected) world with left mouse and right mouse drags, left+right mouse is zoom, left is rotate, right is pan.

I do not yet have the scene objects loaded, nor do I have the animations active. That's next. But this is progress, I can now load data into the webgl, that includes models, textures, and animations.

Here's Gigginox from Monster Hunter 3. Not doing much.

WebGL - Blender Exporter to JSON format

EDIT (2010-04-03): JSON is a bad format. I'm remove support for it in favor of the XML already in place. XML parsers read DXML easily, so the original TED files remain as is. Reason: JSON cannot handle multiple nodes with the same name. Crippling.


Since I already have a very heavy exporter built for blender, and it just so happens to be in the DXML format, I can directly convert it to a JSON with almost no loss of information.

So, if you are frustrated with not having a prebuilt Blender -> JSON exporter, use mine (or copy + improve on it).

The download link is always on the right hand side of my blog, or here since this post is about the exporter:

http://www.gocaco.com/temp/igtl_export_ted.py

You might wonder "why do I want yet another stupid format". GOOD QUESTION.
The "TED" file is designed to mimic hardware formats.
It exports:

• Optimized mesh data (automatically splits along UV seams, and material seams, and matrix palette splits. Exports vertex, texcoord, normal, tangent, weight, weightindex, maybe colors)
• Material information (As much as possible for now, needs improvement)
• Armature data (all of it, including IK chains)
• Animation data (All actions that fit an armature)
• Frame actions (You can make text files with scripts that can act as data for animations)
• Textures (Can be converted to text and put in the file)
• Scenes (Converted exactly as shown)
• Objects (including game properties! And links to data.)

So, it's also all fairly logical. You will have to play with it to get used to it, especially for you novice's out there. Reading through the exporter (find the "const_DTD_ted" declaration) and looking at what the data is should help. Try exporting a regular TED file first, and open it with any text editor. DXML files are regular, very restrictive XML files to promote consistency and easy of reading. It should be immediately obvious how to read them in.

More importantly, for you beginners, the data exporter from the TED exporter is everything you find normally in any commercial game out there. This includes X360, PS3, Wii games, as I have tested and proven myself.
It does NOT export some advanced features, because blender does not have those features yet. Bother blender.org about that if you want more functionality with muscle/keyframe animation.

If you do end up using this, enjoy. Please drop some credit somewhere; there are no restrictions or guarantees to this script. It's 100% free as in free beer.

A early preliminary test:

I will add a animated test soon.

WebGL - YES!

First, go here to update your Firefox (or use Chrome):

http://www.mozilla.com/en-US/firefox/all.html

In firefox 4.0, you have to enable this feature manually,

First type in "about:config" in the address bar,
     Don't let it scare you,
     Sort the items by name,
     Find the "webgl.force_enabled" and double click that to make it true.

Now, go find some sweet OpenGL ES 2.0 type demos.

!!! ACHTUNG !!!

--> Make absolutely sure you have the NoScript AddOn (http://noscript.net/) for firefox first. This will allow you to STOP content from automatically loading, just in case you are like me and are trigger happy.

http://www.khronos.org/webgl/wiki/Demo_Repository
http://www.chromeexperiments.com/webgl

This is great because it eliminates the need for stupid plugins like Unity, Flash, Shockwave, Java, ect...
Now you can use the ECMA script (Javascript) built into the browser to make full powered 3D games, which now are compliant to any browsers that use them!

This is serious cool. I'm totally making something in this.

Synology DS 1511+ - More fun

So far, everything has worked like a champ. The Media server is seen by the PS3, and although the PS3 sucks bawls when it comes to format compatibility, when it CAN play something, it does seamlessly.

We ran a blue ray movie off the Synology, to see how fast it could throughput. The router isn't fast enough to even begin to test, I'll have to get a switch and some better networking equipment before I can.

So, to compensate, we watched a blue ray movie WHILE uploading a blu ray, and had two sources pulling and 1 uploading.

No chokes or anything. A consistent, router limited 10 MB/s.

So that was great.

However, if you setup this unit for FTP, make sure to follow synology's instructions and use filezilla, otherwise you'll get frustrated with other shitty FTP programs.

I still like it so far. It's fast, efficient, very quiet, it's amazingly silent for what it's doing, though the clicking is inevitable in any system.

The temperatures are about 98 98 100 100 99 Fahrenheit in the unit itself under blue ray playing mode. So that's really decent. Ambient room temp is 70 Fahrenheit.

HOWEVER

I encountered one problem, but not with the synology DS1511+. The problem is, VLC.

VLC does not seem to support UPnP/DLNA browsing/playing! What the hell!
I googled this, and found either they do not have enabled, since it seems there are builds with it, or it is not working for just windows.
I was able to download XBMC (oh god I hate it) and it worked fine with the synology, no problems, minus I absolutely hate that media player. VLC spoils you, really!

For example, when watching the dark knight on blue ray, we randomly skipped about and sped up/slowed down the playback and added filters. Still good, though seeking took a moment, naturally. But no longer than I would have expected.

Windows XP Pro seems to SEE the UPNP server, but I don;t have any programs that can browse / pull data off it.

This is a crippling problem, and I want VLC to stream from the NAS.

In unrelated news,

I made the candied citrus peel recipe from the "Desserts By Pierre Herme" awesome cookbook I have; And, OH MY GOD they are amazing. I don;t know what I did wrong, if anything, but caramel + orange + candied is absolutely something else. It's incredibly tasty, and super addicting. Once they all dry, I'll coat them in some crappy ass commercial dark chocolate like Hershey's special dark or something. Maybe.

I'm definitely making these things more often. And I'll quantify the recipe so I can replicate it.

Synology DS 1511+ - Playing around

So, 10TB of a RAID 6 resulted in 5.44 TB of usable space; and it only took about 7 hours to parity check, maybe 1 to build! If you think about it.

10TB / 8hr => 364 MBps

Which, my poor ass router can't go that fast.

So the thing is fast. I started formatting and toying with settings and stuff, uploading movies and music to test it's integrity.

Pending results from the UPnP test with some PS3's.

Remove the DNS so the box is intranet only, which is awesome.

Here's what it looks like in action, using Synology's DSM web interface:

I'm a little hesitant to enable the transcoding on it, but we'll test it out while it's still fresh.

Great job so far guys, this is the best tech product I've ever used. Props Synology!

Synology DS 1511+ - Initial Setup

So, the unit arrived this afternoon.

after a greedy session of package unwrapping, I uncovered the DS1511+ itself.

It looks a lot better than the picture.

Everything is exactly as stated. I had no problems opening the packaging, the instructions were all in a .pdf, easy to follow, the drive sleds were a little flimsy feeling, you have to really be gentle with them.

Basically, you unlock the bay, push in the bay, and it pops out making it easy to slide out. Then, you screw in the hard drive (rubber grommets don't fit for noise abatement, need that fix.) And slide the sled back in, and push the clip back down.

It took me a few tries on the first drive to get it push back enough before it would click back, slightly frustrating, but  it only happened the first time and was user error.

With all the drives in place, I carted the unit into the NAS Room, and setup the UPS for the unit.
The UPS is manditory for any kind of storage operation, since if the power fluctuates, you need a battery backup to keep the unit running until it can shut down and suspend proporly.

I plugged it all in, and installed the Disk Manager software.

Now this part is a little hairy, but my systems have auto-everything disabled. So, I manually allows the autorun, and a little splash window popped up, and you click a big install button. Wait a minute, then you detect your NAS.

Initially, nothing. I check the ethernet cable, and I guess it had wiggled out. So be careful with those ethernet cables, make sure you have a good connection physically.

After that, it blinked on, and I logged in.

From there, it got easy. The Linux OS they use is really damn clean. It works through a web browser nicely, I had 0 trouble using it. Was like home.

More interestingly, is that using a OS like that in a web browser (aside from being really stupid imo) was insanely easy to do. Kinda like using a strong VNC/RDP connection.

So, I clicked arround, made some user accounts, setup  the RAID6 array, and let it go ahead and check everybody for errors.

So, it should be done tonight.

I'm impressed with this product. Using their software online as a testbed was a good way to test it, and getting the unit in a flawless configuration was a really nice bonus as well.

The next test will be to load it with data, and yank out a drive to see how it rebuilds.

BUT, I probably don't need to do that. It seems perfectly fine to me, I'd rather make sure the UPnP stuff works for the PS3's and the Mac in the house, so I can stream stuff to em.


SUMMARY PROS:

• Easy Setup Physically
• Amazingly easy software setup
• Works so far
• Unusually quiet
• Able to add DX510 units to expand the unit's capacity greatly (26 TB theoretical! 16 TB probably max due to FS problems)

 SUMMARY CONS:

• Drive bays a little flimsy
• No anti-noise grommets for hard drives, nor is there room to add any
• Uses a web interface (However, it has a VGA port and USB ports, I bet you can run it with no web interface. Not yet tested.)
• Filesystem limitations come into play unless you smartly divide the drive out. Which is really hard to do, initially.

SATISFACTION: Yes

Until next update!

Synology DS 1511+

So I purchased this baby, it should be here in a week. Maybe more since our atmospheric conditions are trending to the less than favorable end of the spectrum. Loaded with 2 TB drives, I'll configure it as a RAID 6 or equivalent level of protection NAS.
This represents the first serious move I have ever made in the attempt to clean up and organize the vast amount of data I have acquired. Having a HD video camera sucked all the little magnetic pikmin out of my drive platters so fast you'd think it was some sort of monster movie. But, since I have about 3.7 TB of data and almost a literal million files, I figured I needed some way to back up this garbage; the important data only amounts to about 400 GB or so (models, music I made, data, programming) and the critical data still fits on a CD (core code, finances).

So, package wise, this NAS seems to be one of the top products out there. When I get the unit setup, I'll do a full review on it. So far it looks great, and very promising in the software end.


in the meantime, I've been attempting to fix a blender problem, which has been exceedingly difficult for no good reason. (I implemented the fix myself in C/C++ in an hour or two, and got it to work fine) I've been fighting it for over a week, and I'm still not anywhere close to done. Well, that's a lie, but it's not perfect yet.
The script, for those of you who use blender, lets you edit an armature, and it then corrects  your animations after you finish editing. That way, you can model, tweak your armature, make a animation to test, and not lose all that work in the process. You will still lose some, in some cases, since moving bones cannot be corrected; but rotating them or changing their roll can.
I know, it sounds simple right? The problem is the data is stored in local keyframes, as you know:
Parent Matrix * Armature Default Matrix * Pose Matrix = Final Matrix
And you simply solve for Pose Matrix:
Pose Matrix = Armature Default Matrix ^ -1 * Parent Matrix^-1 * Desired Final Matrix
So that applying the pose gets you the desired final matrix.
For whatever weird reason (mostly blenders shitty internal representations of rotations & poorly constructed math utilities, I'm sure many people suffered this) it doesn't. I'll figgure it out eventually. I seem to have rotations working, but not positions since positions apparently come from a different space transform or some silly thing.

Platforming game was going fine, as usual, artist hit RL problems, so I don't know what I'll be doing with it yet.

Played with Unity some. Using Unity makes the Blender Game Engine look good. And that is seriously saying something. And that something is that unity sucks*. But, what do you expect for free? It suffers from the same problems all game engines have. Oh well, it's still fun to mess around in. Did everyone just forget BGE had a webplugin too? Or did Unity just steal their source? Who knows.

Also, work is hard, and we're upgrading what I'm doing again. Fun stuff.

Peace out folks!

2D Platforming Game

Well, I had a dream one day, December 1st or something, where I was instructed how to make a platforming game.
I woke up, coded it, and it worked.
DAMN simple too.

Given a list of AABB's in space, and Actors which contain AABB's for motion against the level,
Simply calculate the current bounds and previous bounds (stored)
then detect any EDGE crossings based on the difference from the previous/current bounds for edges;
Then take the minimum edges found, and move the character out from those edges, with some epsilon (in flash, 0.1 works)

To fire a laser in the game, use a space hash (Make a uniform grid of blocks that store references to the objects) and use a specialized edge traversal algorithm, that moves to the next best slope cell, and check everything in that cell until the laser is exhausted or hits something. Handle the case if it changes a major cell, and check the next two to avoid errors.

Both these ideas work PERFECTLY, and thus any 2D platforming game (without ramps so far) is easily made.

Once I clean up the engine, I'll post it so people can make their own high-powered 2D platformers.
