I have an app that is running slow. I have narrowed it down to several functions which are trig-intensive (used to calculate the position of the moon at a given moment and more specifically to calculate rise/set times).
To calculate the position and rise/set times for a month on average, requires: 300 trig functions for position 24 points in time to find the correct set of three points 30 days 2 events Total of 432,000 trig functions (mostly sin and cos) On my iPad 3, this takes about 3 seconds, and on my desktop (2.3GHz Quad-core i7) it is nearly instantaneous. I am using doubles (not floats). What can I do to speed this up? _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
