Hi Frank,
I've been using the Building Blocks JavaScript plugin that you helped
me with years ago to model periodic waveforms on three axes and on the
axes of the sphere all of which are controlled by notes of the musical
scale. The combination that has me stumped is the A, C, E triad. The
attached file includes the JS script and the path of the sphere does
not return to the starting point in the number of frames that I have
assigned .... no matter how many I use .... I've gone as high as
25,000. It seems to need about 15% more frames than I assign no
matter how many I use. This doesn't happen on other note
combinations. I don't think it is a non-recurring cycle. I'm using 30
FPS. Any thoughts, suggestions. I also discovered that the sequence
of spheres file grows much faster when the realtime renderer is turned
off .... Duh!!!! The things I learn while beating my head against
the wall:-)
I'm finally getting access to our Stereo-Lithography Printer so I'm
looking forward to seeing these forms in the real world soon. I'm in a
course that is using Rhino to interface with the Stratasys machine and
the instructor says that the best import/export is with the IGES
plugin. So, I'm trying all of the possible formats before I spend the
$200 for the IGES plugin. So far .3ds is working pretty good.
This 12 input oscilloscope draws some VERY COOL sculptures ......
Thanks much for your input on this and for your many contributions to
this forum.
Cheers, Chuck Henry
Hi Charles,
Without knowing what all the numbers mean its very hard to comment on
the problem. I am not really a maths person but I assume that as the
initialisation of the variables is based on Sin their numbers should be
based upon a factor of PI to complete a circuit which they dont appear
to be, also the time may need to be a factor of the frame rate 30fps*100
for example. But these are really only guesses.
Good luck with your project,
Frank "The Rookie" Dodd
