Re: [nebula-dev] Flow widget

Thanks Nicholas,

Yeah, loading images and creating textures (I think that's because of TextureIO in JOGL) are slow. But once the textures created with the images, it is fast enough, and the animation is smooth. If the application loads 30 or 40 images, probably it would be ok, but if the application loads 1000 images, then it would take a while to load all the images and create the textures. To load 1000 of images, probably the app code may need to create each item and set the image using display.asyncExec or something like that... The UI might be a little sluggish until all the images/textures loaded. That's one of the areas we would need to look into in the future.

Hi Hiro,

This is a very nice widget and I hope it will be able to pass the ip review. I made a similar widget in my open source project "Sharemedia" but I didn't have time to turn it into a generic one.

Is your widget able to load images on demand , without slowing down the next/previous animation ? This is something I had issues to achieve with LWJGL.

Nice work.

Nicolas

Thank you Tom,

I updated my comment on the bug report.
In my opinion, a couple of possible options:

1) remove JOGL lib from the project simply or
2) replace JOGL API with OS OpenGL API. (it would take a while to do this though)

btw,
another concern is Flow widget requires JavaSE/Java2D, since JOGL depends on JavaSE/Java2D (like BufferedImage, Rectangle2D so on)..

Hi,

Thanks for your contribution the widget looks awsome! I've added a
comment to the bug and JOGL CQ.

For all of you not following the bug: The problem is that this cool new
widget needs OpenGL and there's currently no approved 3rd party lib at
Eclipse.org to interface with OpenGL :-(

I've CC'ed the gef3d people who know best the status on 3d@Eclipse.

I'm not sure but probably our position is better than the one of GEF 3d
because we could define JOGL as an prereq which has the draw back that
people can't get an all in one download from Eclipse.org.
