Verse integration for Naali

jesterKing — Tue, 03 Aug 2010 15:02:19 +0000

During the summer I’ve been working on a simple Verse integration tech demo for Naali (RealXtend). In short, Verse integration is for having a low-overhead and fast protocol for EC (Entity Component) attributes. In this techdemo I’ve concentrated on setting light attributes and a way to have Naali keep book of world objects and map them to verse nodes.

I have recorded a short demonstration in which I show how the light can be set using an external tool that has Verse support, in this case the Connector scene graph editor from Quel Solaar.

Implementationally the Verse integration is done on the level of Primitive class, where Primitive will connect to a verse server when instantiated. Upon accept Naali will then subscribe to object nodes and for each object node it receives it will also subscribe to changes.

When a new object is created in Naali, also a verse node is created, to hold and communicate changes to EC_OgreLight.

To keep track of the different objects on different servers there are three maps, one to map RexUUID to VNodeID, one reverse VNodeID to RexUUID and then an extra RexUUID to entity_id_t to speedup lookups when receiving updates through Verse.

When Blender gets again proper Verse integration this will be especially interesting when thinking from perspective of content authoring using external tools. Blender is already a great modelling and content creation suite, and with Verse it’s easy to write simple, small tools to do a number of tasks (texturing, scene decoration, mesh changing, audio attaching, etc.)

VerseSharp implementation continued

I’ve been working again on the C# implementation of the Verse protocol, versesharp. This work I’ve been conducting in the branch coderestruct. I’ve managed to implement all object, geometry, bitmap and material commands, and about all system commands are there too (ping still missing). For now I leave text, curve and audio commands out of the loop, and will start working on some kind of server to see how well this all works. I still think session handling needs a lot more improvement.

One reason to work on this again is the possibility of having Verse used in RealXtend, and it was a good way to ensure I am familiar enough with how Verse works. Alongside I’ve been trying to work out how it can be used. The idea is to have EC attribute syncing done over the Verse protocol to ensure minimal traffic and package overhead between Naali viewers and the EC attribute server (which thus will be a verse server). How this exactly will work out is something to investigate during the next month.

BMesh win32 test build (r24303)

I’ve created a win32 build of joeedh’s bmesh branch. See his call for testers for more info (note the redmine link for bug reports!).

So grab your build and start testing and reporting!

Before you start reporting issues:

NOTE 1:

his redmine installation has a copy of the users from http://projects.blender.org. If you have already an account there, you need to reset the password here (forgot password). This to make sure that a proper password is generated for your user account.

NOTE 2:

If you managed to create several accounts on projects.blender.org using your email address, contact me.

Fresh win64 build: Blender 2.5 AMD64 r18932

I have created a new build for 64bit Windows machines. The download is available at graphicall.org. Please test the binary if you have the possibility to.

The build has been created against SVN revision 18932, and there are no debug symbols enabled. I still have uncommitted tweaks in my local tree, but if you’re interested in seeing what the scons configuration is that I use for building:

New 64-bit Blender 2.5 build for Windows

jesterKing — Mon, 02 Feb 2009 01:32:17 +0000

I have created a new build of the Blender 2.5 branch for 64-bit Windows. Currently these builds are still very experimental, as many of the dependencies need still to be built before they can be used.

Despite the missing dependencies, this build is ready for testing. It is created on revision 18787 from the Blender SVN repository.

Download the binary from graphicall.org.
