Default <!> [T] 3D Model Demo

I've been working on this for a day or two and figured it was basically finished. This is my 3D model viewer for the Zune HD. It takes a model from Blender and, using a special python script, creates a file my program can read. It then displays the file on the zune in its full wireframe glory!

+ YouTube Video
ERROR: If you can see this, then YouTube is down or you don't have Flash installed.


Sorry the video isnt very good, blackberry camera :\

Anyways:
One finger: rotate camera around model
Two fingers: Zoom camera in and out
Three Fingers: Change model's color based on the Y values of your fingers (horizontal if the screen is landscape)
Four Fingers: ?? (try it and post here if you know what it is )

The model that appears at the start is the default monkey from blender. It is facing towards the sky which is why it looks a little strange.

Any questions or comments please post. I'll be happy to answer!

this is great! do you have any other available games other than light cycle?

and it appears as though 4 fingers changes the model... to a fat guy. awesome.

placing two fingers o the screen at once, and place a third while holding the other two on there zooms in a certain amount immediately. or if you drag that third finger it alters the color in shades.

whats the first one? a monkey head?

The only other game I have was my first one called Popem, some people liked it but I didn't really continue making it. That was when XNA first came to the orig zune. It wouldn't run anymore on zuneHDs and im not sure if it is compatible with the newest iteration of the zune firmware either. For the ZuneHD just this tech demo and Lightcycles, it just came out 3 days ago, one person can only do so much ;P

And yea, the first is a monkey's head. It is a default shape in Blender, so it was the easiest thing I could get that wasn't a box. Thanks for pointing out the actual bug of if you place 2 fingers and tap the third it zooms in. I know why it is happening and will fix it sometime soon.
And it isnt just a "fat guy". If you look closely he has some slight features that might help figure out what he is. Heres a hint, he is from a popular video game

wow, great demo. i didnt download it yet so i dont know all the features but you should make it turn in relation to the accelerometer (if it doesnt already do this).

meaning you tilt the zune and the figure stays level i guess? idk how to describe it right now

Um from what I have seen (from Lightcycles's FPS) the ZuneHD and the normal zune have about the same FPS on similar apps. I'm sad to say that the FPS are ~9, but you can't really tell. Same with Lightcycles, It is defiantly less than what most people would consider good FPS, but it looks like it runs well. When you use this demo it doesnt really feel slow due to FPS...at least in my opinions. Maybe others feel differently. I suppose you need to run it to see. No use of the accelerometer yet. Not sure if I will add it in, but it is possible. Wont promise anything, but I might take a look at it for fun.

It is possible to optimize the engine further I believe, I just haven't done it yet (heh not sure if I will)

Also no, not kingdom hearts

Wait, the ZuneHD runs at the same speed as the older ones?

From my 100% informal tests it seems about the same. But it also has a larger screen, so it is drawing to more pixels at the same time (also rendering more lines), but it isn't a huge jump in processing power as far as XNA goes.

(I've posted about my viewings on the performance here and on XNA's official forums. So far it looks like I am the only one that has ported a game, and am pretty hesitant on my findings. My game/app is kind of an outliers as far as performance is concerned, so don't take my findings as fact.)

Oh and blender is a 3D open source modeling program on the computer. It is free. http://www.blender.org/

If anyone has a 3d low poly model they would like imported let me know. I'll see what I can do

Its a boomer from Left 4 Dead. http://media.moddb.com/images/groups...art-boomer.jpg
Not the most obvious, but you can still see the neck growth heh.

Anyways the .ccgame file is updated to have the zoom fix from 3 to 2 fingers. Just redownload the file and resync and it should be fixed
