Feedback please - Render Terrain Widget

Anonymous User

Hi, I've created a widget to create a simulated terrain model of our LiDAR data. Please, try it and let me know if the user interface - tilt, rotation and freeze is user friendly, thanks!

gis.macombgov.org/flexviewer2

The widget is under "I want to..." Render Terrain.

Great feedback Noah, as for #2, if you click the "N"(north) - rotation resets. Every "Build Rendering" will reset the height exaggeration silder to the default exaggeration for that scale. But, I will try a "reset to default" button.

I attempted having listeners for every change in the map - to rebuild the rendering on every extent or TOC change. But, I didn't like having so many listeners running. So, I thought the user should be in control and have "Build Rendering" and "Hide Rendering". But, maybe I will re-evaluate that, too.

as for #3, the dimensional math is pretty intensive and the computations can greatly task the users CPU. Some devices have no problem at all. Actually, three dimensional modeling on a web browser is not very common. I can make it run "smoother" - but the cost would be the quality. Maybe, I should give users a choice of "low resolution" or "high resolution".

as for #4, the missing "x" - this was a release-build compile issue and should be fixed.

Thanks for saying the widget is good. I'm not sure of the usefullness of the widget. But, like you said, I think it can give users another point of view to evaluate a map location(another perspective). And, make our GIS maps a little more entertaining to use.

Hi Dan,

I checked out the widget, very cool. Here's my feedback:

1) Pretty easy to figure out. It took me a minute to understand how the ball worked, but once I did I enjoyed playing around with it.

2) Rotate and Exaggerate height worked pretty well, but I found myself having to constantly reset the settings after I stopped rendering and moved onto a new area. Perhaps there could be a way to reset those settings to default? Like true north and middle (or low) height perhaps.

3) Sometimes the map "twitches" and moves very, very slowly after double-clicking to freeze, and this can become a bit unsettling.

4) The close button was missing (usually the little "x" in the top right).

Overall, this is a great widget and a very cool use of the Flex Viewer. Thanks for sharing!

Viewed in Chrome.

Looking good.

If you build a rendering, then hide it, then build it again, you will get the TOC null values error.
If you pan/zoom some before re-rendering, the error does not pop up.
After this, in your Layers button, the spinner never stops "Loading Layers".

Other than that, nice job. I not only like the renderer, but the layout in general.

Running Firefox 21.0 and latest flash (content debugger). No problems performing all your requested activities. Interesting widget, also like the dropdown list of activities. Please post code when done.

Thanks for the feedback. I think I've fixed most of the errors. Now, as far as the http://gis.macombgov.org/flexviewer2

Using the "Render Terrain" widget - under "I want to ..."

For feedback - as far as ease of use, turn on the Satellite 2010 photo - zoom into some buildings - hover over ball, freeze, rotate, exaggerate height, unfreeze, hover - any suggestions - does it work without much effort? thanks again

I am using IE. When click on "Satellite" button I got following message. Would be nice move all your hotizontal years button to middle so won't cover the satellite button.

I think I fixed those errors. How do I get to see those debug errors? I never see them. I'm compiling actionscript on a test webserver . . . debug mode has issues. Sorry, I'm just a self taught programmer. But, I do understand 3 dimensional math.

Yes you fixed the initial load issue. I'm checking out your app. now.

Just need to download the debug version of flash player for you browser, either IE or non-IE basically.

http://www.adobe.com/support/flashplayer/downloads.html

Check out the ones that say Content Debugger.

Keep in mind, there's a lot of sites out there with Flash issues so it does get a little annoying sometimes having the Debug version installed.

I too would be interested in the source once you get it working correctly.

for now, on initial load:

Then, if I continue with the debugger window, once I click "Build Rendering", I get:

TypeError: Error #1009: Cannot access a property or method of a null object reference.

Then it renders the layer..

Locked up my Flash plugin on initial load.
Can you share the source code for your widget or application?

Did the entire flexviewer lock your flash player or the widget?
What browser? What type of device and OS?
I guess if you can't even look at it - feedback is impossible.
This widget is under development and I'm still making it.
