Cost of implementation Bullet medium Havok high Newton low PhysX high Performance Bullet good Havok good Newton good (can run asynchronously and use multiple threads, so LE2 physics speed is not as fast as it can get) PhysX best iOS/Android support Bullet yes Havok no Newton yes PhysX unknown Soft bodies Bullet yes Havok yes Newton no PhysX yes Destruction Bullet unknown Havok yes Newton partial PhysX yes Forest physics (for lack of a better term) Bullet unknown Havok no Newton yes PhysX no Source included (not too important to me, but...) Bullet yes Havok no Newton yes PhysX no Based on the lack of iOS/Android support, it looks like it comes down to Bullet vs. Newton. Bullet has soft bodies but Newton has the special forest physics that make our big scenes possible, and my Newton character controller works well. It's a tough call.

I think cable costs about the same, and has better speed.

I'm uploading another backup from January, but there's nothing useful in it. It's mostly just to prove to them none of the backups generated contain the databases.

First, so you don't have to read through all my rambling, the website database is set back to November 2010, and there is no way around it. I was working with the forum software on Sunday, 4-17, and I was just very pleased with how things were working. I saw there was an update for the bug tracker application, and the change list just mentioned some bug fixes, so I felt okay installing it. The new version removed custom issue fields, which we use extensively for listing hardware, drivers, operating systems, etc. It's not very easy to revert to previous software versions. I had performed a full website backup earlier that day, so I figured the best way to revert the tracker app would just be to have the IT admin revert the server to the backup I had made. I'd downloaded it to my local hard drive and it was intact, and also still available on the server. I also had an earlier full website backup I made on April 2. I figured this would be a minor inconvenience that would take the forum offline for a few hours. Here's the interface in CPanel: I also talked to the IT admin and they assured me that the full website backup does includes MySQL databases. I sent the following message to them Sunday afternoon: My caution in this email might indicate I had a suspicion something was wrong. Did I somehow know something would go wrong? Should I have? This thought is nagging me right now. I've been on the phone with tech support for a couple days, but you don't need the whole story. The outcome is the server was erased and repopulated with the contents of the backup archive. All files were intact, but the databases were not saved when the backup was performed. The previous backup I had was from April 2, which would not be a terrible loss. It appears the same occurred then. In fact, since I have been dutifully saving full website backups since November, thinking I was making extra effort to be on the safe side, the databases were never being saved in the archive. So the last copy of the forum database I have is from November 2010. I've been quite diligent with backing the site up, but that doesn't mean anything if the backups aren't working. The host automatically backs up sites under 10 gb every 24-36 hours, but that size excludes us. Although it was easy to bring the forum software up to date, all forum data since November 2010 is gone forever. The loss of this is staggering. To me, and to others here. You can get your screenshots here in a single package. They're randomly named, but if you really need something you can find it, and it's divided up by month: http://leadwerks.com/werkspace/index.php?/topic/3098-screenshot-archive/page__pid__28584#entry28584 I still have all the attached files from posts, blogs, downloads, etc., but they are randomly named and I don't know how possible it is to go through them. The thing that really hurts is the lost documentation that was created after November. That's going to take time to recover from. We'll recover, but the loss is still sinking in for me. Jorn worked really hard on that at a reasonable pay rate and I feel really bad about it. I have records of all registered users. If you registered for your Leadwerks account after November of 2010, your account will be recreated and your password will be set to your registration key you received. The wiki and old forum are fine. The new forum skin is fine, but not installed at the moment. This must never happen again. First, a better backup protocol is needed. The most important thing is that the backups actually be valid backups. Obviously, I've learned that MySQL databases must be backed up individually and that a full website backup from CPanel is not reliable. Data is saved to a 2 TB external hard drive. Additionally, I am opening a safe deposit box where code and site data are regular deposited. I already thought I was doing everything right, so at this point I feel like I can't be too careful. Second, I am locking the forum software at the current versions, unless a critical vulnerability is discovered. In 2009, all we had was an installation of PHPBB. The idea for Werkspace was something Annika came up with and gradually sold me on. We listed all the features we wanted and found forum software that would allow it. Customizing the look and feel of the software to fit in with the theme of Leadwerks was a long process, but we finally got a suitable skin made. I am satisfied with the features and functionality of the system, and now we can just leave it be, indefinitely. The data loss does not affect the skin we had developed. The skin will continue to get minor improvements, but those kind of changes are easily performed and rolled back, if need be. Third, semi-annual tests are needed to make sure data can be restored successfully to a test server. Backups don't help if you wait until you need them to find out they don't work. A test server will be used to install the latest backup on every six months, or before any restoration takes place. Maybe this is overkill, but nothing was supposed to go wrong before, and we found out otherwise. It seems redundant to say I'm sorry about this occurrence. I know we'll get back to normal, but it hurts pretty bad. The key point is my data backup technique was flawed, so all the backups I've been performing were worthless. -Josh

You are free to implement your own drivers for device input, window creation, etc.

That's the point of the processor...to get rid of the hierarchy and collapse everything into a single mesh.

I don't know of any exact examples of Blender animations off the top of my head, though it has been done. Leadwerks provides an FBX to GMF converter. If the animation did not show up correctly in Leadwerks the only reason would be because the FBX file data was somehow incorrect.

The GMF processor collapses the mesh hierarchy. So if you do that to an animated mesh, it won't be animated anymore.

The Lua speed is fast, because it is using LuaJIT, so it's really compiled code. You can write your whole program in Lua, or just use scripts attached to entities, or don't use script at all.

The code he posted creates a framework object and sets the Lua variable to that object. Do this first, then load your world, and all scripted objects should have access to the framework object, which is used for advanced rendering settings.

A custom buffer allows you to create the window and handle messages yourself. Creating your own window and a custom buffer bypasses the mouse and key input. Not at this time. Version 3 will support a no-graphics renderer. You can load a background texture and adjust the blend level of each layer. Using a color array in the vertices wouldn't be good because the appearance would change with the LOD level changes.

The GetLuaState functions returns the global Lua state, and you can use the Lua library from that point on.
