But now I have 2 options: to work with tables (reading tables values with tabread and manipulating this values) or to work without tables, manipulating lists directly to extract each value I need. What's the best option in terms of computational effectivity? (I use a lot of data which require a lot of cpu, so I need to minimize computational cost). I will use this video data for audio synthesis.
Using a table normally is faster, especially if you want to access values by index (that is, not sequentially). You can do some optimizations, too: For one, you can get rid of one counter, if you send the RGB-list to:
[list]
|
[list split 3]
|
[unpack 0 0 0]
| | |
... put to tables
Even faster probably is using just one table for all RGB values: Just do a [list prepend 0] after [pix dump] and send the 0-prepended list to a sender with your table-name as target.
You can still access the individual R, G, or B values by adjusting your index into [tabread] accordingly (use: 3*index + X with X = 0, 1 or 2)
