 Task Description

The best time for a picture....

I set the day time and so the position of the sun by “clock=”

Normal I document my source very good, but this time,
I forgot the clock seting for the picture of my book cover.

So I would find it very practicall to put the clock value
and other setings for rendering
into EXIF data of the picture.

 Task Description

October to middle November, I prodduced a 5 minutes video mainly py POVRAY.

Here a part of the video.ini file

#

# szenes based on games.pov
#

#game-pat
#Initial_Frame=450 - time scale 1000 - 30 seconds
#Final_Frame=899
#Initial_Clock=-12500
#Final_Clock=17500

#game-lost - time scale 1000 - 22 seconds
#Initial_Frame=0
#Final_Frame=659
#Initial_Clock=2000
#Final_Clock=24000

#game-lost - time scale 3000 - 12 seconds - fast through the night
#Initial_Frame=0
#Final_Frame=359
#Initial_Clock=24000
#Final_Clock=60000

#book-cover
#clock=64000

#game-sunrise - time scale 1000 - 35 seconds
#Initial_Frame=0
#Final_Frame=1049
#Initial_Clock=60000
#Final_Clock=95000

Now imagine all the problems:

One computer crashes often because of thermal problems.
Last picture rendere 487.

Now calculate the setings, that this computer continues the task at 487

Or 2 computers should render a scene.

Sounds very easy. Something like computer 1 makes 0..499 computer 2 makes 500..999.

But the computers are different in speed and the pictures are
very different in computation time.

So it would be best

computer 1: 0 to 999
computer 2: 999 to 0

They would meet in the middle, where ever this middle is.

So it would be much easier with

#game-sunrise - time scale 1000 - 35 seconds
Initial_Frame=0
Final_Frame=1049
Initial_Clock=60000
Final_Clock=95000
Initial_Task=487
Final_Task=1049

So I have not to calculate the exact clock seting,
when a computer sould continue a task after crashing at picture 487

#game-sunrise - time scale 1000 - 35 seconds
Initial_Frame=0
Final_Frame=1049
Initial_Clock=60000
Final_Clock=95000
Initial_Task=1049
Final_Task=0

This would be the reverse calcualtion order.
Starting with picture 1049 and going down 1048..1047

 231 Image formatFeature Request3.70 RC3Very LowLow Number of digits in file name at an animation Closed
100%
 Task Description

There is a long animation to render.

computer 1 should render 0..799
computer 2 should render 800..1599

And after this, You have a bad surprise with the filenames.

animation799.png
animation0800.png

There should be a seting how many digits a file name in an animation should have.

This avoids, that there are series of pictures with 3 and other with 4 digit filenames.

BTW: All the experiences for this feature requests had been made during producing
