Xith3D Features

[DavidYazel]

This post is to keep updated the different features supported now and in the future of the Xith3D project.  Because we add features so quickly, this is a pace people can look to quickly determine if something is implemented.

Architecture

• Not tied to any underlying API
  
• Under a dozen classes need to be implemented to port to another API
  
• Reference implementation uses JOGL -> OpenGL
  
• Sophisticated state sorting
  

Geometry

• Triangle Array
  
• Quad Array
  
• Triangle Fan
  
• Triangle Strip
  
• Indexed Triangle Array
  
• Loader for ASE
  

Rendering

• Depth buffer : test / write
  
• Alpha buffer : test / write
  
• Stencil buffer : test / write
  

Texturing

• Multi-texturing
  
• COMBINE mode
  
• MipMap, clamping, perspective correction, etc
  
• Loaders for RGB, RGBA and GRAY images from PNG, JPG, etc
  
• By-Reference, auto-flipping
  
• memory and disk caching of textures.
  
• TexCoord generation
  

Transparency

• Vertex alpha
  
• Shape Blending
  
• Shape sorting for back-to-front rendering
  

Sound

• Loaders for WAV and OGG formats
  
• Ambient Sound (Stereo)
  
• spatialized sound (Mono)
  
• Designed independant of any API.
  
• OpenAL and JavaSound support
  

Spatial

• Bounds: Sphere, Box, Frustum, Plane
  
• OctTree
  
• Real time frustum culling
  

Misc

• Shadow volumes
  
• Canvas shape picking
  
• Overlay support
  
• Swing GUI support
  

Scenegraph

• Nested transforms
  
• View based culling
  
• Projection / ortho modes
  
• Local and vworld bounds kept current
  
• Any number of nested transforms

David

what about interpolators/behaviors?

[DavidYazel]

Bump... still waiting for mod privs to make sticky.

David,

Could you please add under the ASE Loader entry that the GROUP nodes are not yet supported to avoid confusion for new users? (issue 22)

Thanks,

Will.

Hi! Do you plan to add to Xith3D scenegraph serialization feature (like   that contained in  scenegraph.io package in Java3D 1.3.1) ? I need it hardly.

[Jens]

I need it hardly.

You need it "absolutely". ("hardly"="kaum" in case you are german)

[kimerinn]

I'm not a german, I'm ukrainian  , and my english is bad, but this does not change the matter: I ABSOLUTELY need scenegraph serialization.

[kevglass]

Infact, "I need it absolutely" isn't very good english either

"I need it desperately" would probably be better. Better still would be "I desperately need it".

Anyway, if you're porting something from Java3D you could just implement at simplistic serialisation.

Infact, "I need it absolutely" isn't very good english either

"I need it desperately" would probably be better. Better still would be "I desperately need it".

You're right of course. I tried to correct it, because I thought people can really misunderstand it.

[kimerinn]

I want to switch from Java3D (by rumours, it is dead), but, unfortunately, I can't. Xith3d has not scenegraph serialization, and it is too much work to do it by myself. So, when Xith3d has, I'll switch on it, but now I'm stay on j3d.

[abies]

Do you need to be compatible with java3d serialized data, or just be able to serialize/deserialize inside xith3d ? In latter case, it should be not so hard to add support for serialization.

[kimerinn]

I need only ability to serializa scenegraph, compatibility with serialized java3d scenegraph is not needed

[abies]

Then don't give up kimerinn. I'll start up a thread about scenegraph serialization and we will see what can and what cannot be done.

[kimerinn]

thanks a lot

Hi all. Here is one great "feature", that java3d has and xith has not: a good one-file installer. I've read xith installing tutorial and feeled that only few "dumb" users will use xith because of sophisticate install procedure.

[Jens]

What do you want the installer to do? I don't know the Java3D installer, but if you have an Xith3D installation you probably don't want to modify the installed JRE of a user, because of several reasons (e.g. your app is usually tested and stable with a certain combination of libraries). All you need is a startfile, which puts all the libraries in the classpath and library path and then starts your game.

[William Denniss]

yeah - and since Xith3D is targeted at developers, we assume they are competent enough to install it (and we've got a lot of docs to help them).

Currently everyone pulishing stuff is bundeling their own versions (ie. their own installer or JWS).  A generic installer could happen if the API stabalises but it is far from that.  It also is a large task because you have to think of multiple platforms and versioning.  Maybe ask this again in a year

Will.

[William Denniss]

David,

Can you please update this line (under Geometry) to reflect the fact the loader does support GROUP's now:

Loader for ASE (does not support GROUP node)

Will.

[Java Cool Dude]

Add TextureCubeMap, FragmentProgram, VertexProgram

[Herkules]

Add Fog

[Herkules]

clear definition of 'Background' concerning Z-buffering, Z-clipping, other renderstates (transparency?)

[aNt]

+1 fog

[javazoid]

Add Text3D (important), Text2D (less important)

[Amos Wenger]

This list isn't at his right place. I think it should move on to xith.org, where anyone registered in the tiki-wiki and with the proper rights can edit.

[Amos Wenger]

Following my remark, Features is now an article under the new Xith website (http://xith.org).
