is that a bad thing?
Richard Carter at 18:46 PM, 17 Aug 2011 via web
not really, but I'm more used to smaller fonts.
Charles at 18:47 PM, 17 Aug 2011 via web
so i have mixed feelings about the choice of XNA. i was looking forward to learning (more) opengl. :-\
Richard Carter at 18:48 PM, 17 Aug 2011 via web
I've used xna before, mostly for 2d stuff, It's nice, C# makes it real easy.
Charles at 18:49 PM, 17 Aug 2011 via web
Yeah, I was looking forward to OpenGL
Stephen at 18:49 PM, 17 Aug 2011 via web
yeah i'm okay with it. but for example i wanted to further my opengl usage on android, and i figured i might be able to mix that with class.

nah, I have an android phone, I've yet to meet some one with a windows phone.
Charles at 18:53 PM, 17 Aug 2011 via web
yea that's a good point, i've never seen a windows phone in person either, their sales must be terrible
Richard Carter at 18:54 PM, 17 Aug 2011 via web
though it might be cool to get a windows phone for development for the stuff we do in here.
Stephen at 18:55 PM, 17 Aug 2011 via web
it would be cool, shame non-contract phones cost so much.

I was looking forward to OpenGL as well, but whatever

So I started an Android raytracer today. Got it "working", ran it with a single sphere as the scene, and... it draws a rectangle. *headdesk*
Richard at 02:07 AM, 26 Aug 2011 via web
I'm guessing it's a rounding error or something. Graphics are so hard to debug.

I found this example worked for grabbing the vertices. http://goo.gl/voyI9 - I am yet to look into accessing the index buffer though.
Richard at 19:00 PM, 12 Sep 2011 via web
Actually looks like it also can get the index buffer as well. I looked at it line by line to get a sense of how to get the vertices from XNA

Richard at 00:54 AM, 28 Sep 2011 via web
Has anyone figured out good values for phong lighting? I haven't played with it yet, my first guess is turning out to be really dark though.
Richard at 05:38 AM, 28 Sep 2011 via web
Also, reminder to ask Prof Watson: 1. sample file name?, 2. reflection percentages?, 3. do we need to render model color/texture?

Is it:

Bounces?
Or just one value for pixels?

XNA GraphicsDevice.Viewport.Unproject can be used to calc world space location through projection plane
Jim at 14:33 PM, 08 Oct 2011 via web
A good intermediate step for testing your 2D projection plane is to draw all model vertices as points (short lines) before any ray casting.
