Everything's possible, but not everything's fun...


« Posted 2006-03-24 18:18:20 »

We need testcases for :

- NVidia stripifier
- Transparent rendering & opaque/transparent shapes sorting
- Multipass rendering (MultipassView class)
- The different renderers : JOGL, LWJGL, JSR231
- Texture anim (other than the "Fun with textures" tutorial of the GSG)
- Bounds (and we need to fix showBounds() method, since it's bugged)
- OrderedGroup Testcase done by arne on 24/03/2006, not working
- Skybox
- Primitives
- Billboard

Oh, and I think we should erase the "Xith3D" prefix in front of the test/demos class name.

EDIT : And split the test package, too.

not so necessary I think that's unnecessary work (ok it doesn't break any code, I don't think anybody uses those examples in their application)

No! No! No! This sounds as if it works, but it doesn't!!

- Skybox
used it without problems, but it's some kind of confusing if you don't have y up

- Billboard
used it and works, but it doesn't orient in all axes to the view. Because I needed it for bomb-explosion animations I copied it and modified that version, extending it was some kind of impossible or with too much overhead - an example of the modified Billboard class is in the SpaceBomber project. (the project is fairly dead now - not enough people here in the forum to invest some time in it - nay maybe simple examples for each xith-features are better anyways)

Hi,

Consider adding ARB_point_sprite support for billboading - in this case, graphic card does everything for you. It will be also useful for particle systems - will reduce CPU load factor of four in some cases.

Billboard can be used to implement auto-oriented groups of real shapes (not just textured rectangles)

At the opposite I think this would be nice. You can then test each class or package and it's more clear :
See my logic :
com.xith3d.scenegraph.Billboard -> gives test : com.xith3d.test.scenegraph.BillboardTest
com.xith3d.render.lwjgl -> gives test : com.xith3d.test.render.LWJGLTest
And yes it doesn't break any code, except the JNLP on the Xith3D demos page.
And I propose that cause I can do it, don't wanna annoy anybody with that.

Changed. Is it better ? If it would work, it would be green.

That's an issue. Theoritically users can use whichever axis they watn to be up.

Do your modified version do all the things the original version do ? If yes it should be included in the core.

Can you do that ?
I don't have enough OpenGL knowledge for that. I can do it but I'll have to spend some time on learning how to do it.

It gives quite a different result.

I think Yuri's idea is the best. Billboard will then have to become a Group.

Yep. That was my original concept of the Billboard until I looked into the Billboard.java file, though.
