Light Curves Of A Fractal Asteroid
This is a neat little Idea.... Maybe one day I'll do somehting
useful with it (authors note  2 years on and I've still to do something
with it).
Using my little fractal asteroid generator I thought it would be
fun to vbuild a hypothtical asteroid and see what kind of rotational lightcurves
it would produce. There are a lot of free variables here  asteroid rotation
axis, illumination direction and then there's a whole slew of surface properties
which I could look at.... anyway here' a few examples...
Test Asteroid Rotating
LIght Curve Graphs For a Range of Illumination Angles
0 degrees


45 Degrees


90 Degrees


135 Degrees


180 Degrees....


225 Degrees


270 Degrees


315 Degrees


All these angles are taken with respect to the viewer, and in the
plane of the object's rotation. The Values are Log(Brightness)  don't
read too much into the scales they are dimensionless  calculated by pixel
counts. The xscale is the angle of rotation in Degrees  the long axix
begins at 90 degrees to the viewer.
