FoodI have not been eating as well as I would like to be. I have been eating out way to much. I went a restocked my fridge and am going to start eating better again this week.
EquationsI have been playing a lot with SAGE and implicit modeling. It is very cool to have this:
c = Tetrahedral (18,18,60)
sp = Sphere(1.5)
sld = Join(c,sp)
swplt = Plot3d(sld,5,100)
where you just define the individual shapes like this:
def Tetrahedral (a,b,c) : return ((x^2 + y^2 + z^2)^2 + a*x*y*z - b*(x^2 + y^2 + z^2) + c)
def Sphere (r) : return (x^2+y^2+z^2-r^2
and a join like this:
def Join (a,b) : return Min2(a,b)
And what comes out is:
ExersiceI went for a run this morning. It was not a very long run, but it was a run. I think I am going to join the "Movers and Shakers" club at work. That is where you get a pedometer and log your miles. You then get prizes at certain points. It might be a good motivator....
LasersI think for my final project in my rapid prototyping class we are going to test and use a 3D scanner setup using free software called DAVID (http://www.david-laserscanner.com/). What is very cool about this is that it uses any camera and a laser with a line diffuser on it. You use the laser to scan the surface of the object while the camera records the shape of the line. This is then converted into a 3D shape in the computer.
