Timing issue

[Uttama_vizard]

While working with avatars moving dynamically on the virtual screen, I want to record the x,y,z coordinates of say 'head' of an avatar. For this, I am using

print "male1_head_position:", head1.getPosition(viz.AVATAR_WORLD)

This is giving me the coordinates.

In addition, I want to record the system time instantaneously, so that I can correlate the 3D coordinates of say, head of an avatar at a particular instant with some tracking data. From the "help" coming with Vizard, I am getting the elasped time, but, I am not getting the particular instant associated with a particular 3D position of an object.

Can any one suggest me a solution to this?

Thanks in advance.

Use viz.getFrameTime() to get the current absolute time of the frame.

Thank you so much.

But, I am getting this display as output

male1_head_position: [0.0054466063156723976, 1.7178937196731567, -1.9990379810333252]

male1_head_position: [0.0054466063156723976, 1.7178937196731567, -1.9990379810333252]
158.816147862

'2' indicates my second looping of the program. In fact, it shows that the frame time is doubled in the second looping of the program.

What, I wanted is to display the system time in hrs:mins:secs format.

Your suggestions are very helpful.

Thanks

The viz.getFrameTime() function returns the current time in seconds. You can use the time module to format it for display. The following code will format the time to hrs:min:secs:

import time
print time.strftime('%H:%M:%S',time.gmtime(viz.getFrameTime()))

I am getting the output as

male1_head_position: [0.0054466063156723976, 1.7178937196731567, -1.9990379810333252]

But, this is the elasped time. I wanted the system time in hrs:mins:secs format.


Thanks

Have a look at the Python documentation for the time module. It describes all the functionality you need. In this case you would use the time.localtime() function:

time.strftime('%H:%M:%S',time.localtime())

Your suggestions are really valuable. It works great.

Lots of thanks
