Real Time Graphics Asg03

Now that I actually understand the graphics pipeline a bit better, this assignment was quite a bit easier.  I understood immediately what the light class would look like and understood how everything was going to fit together.  It was just a matter of figuring out the right method calls and changing the Mesh file into something more readable, you're welcome, I think string parsing in C++ actually physically hurts me.  ;)  Anyways, here's the assignment for the randoms reading this.  Basically this week we had to texture our cube and apply lighting.

The controls are the same as before, WASD controls the camera, the Arrow keys control the cube, and IJKL controls the light source.

The troubles I ran into this week were all kind of trivial.  First of all, I don't know if this was brought up in class, but the UV coordinates originate from the top left.  It seems like each individual aspect of the DirectX graphics pipeline uses a different origin..

The second issue was I assumed the D3DCOLOR object in the s_vertex was size 12 because its three ints, but I guess I was wrong.  That caused my texture to be drawn horribly wrong because I used the wrong offset into the struct.  That took awhile to fix, really Sherly figured it out.

Another aggravating issue is I used the word texture in my fragment shader, which must be a keyword or something.  I should probably get a syntax highlighting plugin.  The error just said something like 'unexpected token texture'.  I just changed it on a whim to texture_sample and it worked.

Finally, I couldn't tell if my light was actually moving at first because moving it at the same speed as the camera and the cube.  I'm guessing changing it by 1 has such a minuscule effect on the angle hitting the cube that you have to move it really far to notice.  I changed the controls to offset by 10 at a time and it works much nicer.

Here's my required screenshot.

And here's my code!

P.S. Jason and I worked together so that's why we wrote about the same issues.
