This is the patch which controls the middle screen within my installation, this patch is different from the outer screens one since 5o% of the time it plays clips of the Canary wharf building in a portrait ratio and the rest of the time it plays footage from my database in a landscape ratio.
Now that my installation is fully functional I can make adjustments and improvements as they occur to me and I intend to conduct some fine tuning of my Puredata patch between exhibition opening hours.
This is the final version of my pure data patch for the outer two screens.
It is very simple, but still the most sophisticated patch I have built to date.
The metronome object is used to synchronise the play back of ‘random’ (referring to the random object within P.D) videos and sounds from my data base and also to alternate the position of two Gemheads within the screen space.
Outer screens top level patch.
The videos within my database are organized based on the themes – Inward, Outward, Left to right and Right to left. The movselectA and movselectB objects are nested within my patch. The random number object is used to select a category and then a clip within that category.
This is the same as movselectA only the categories are inverted, thus if category’ inward’ is selected in movselectA then category ‘outward’ will be selected in movselectB.
wavselectA + wavselectB
There is one unique sound for each video ‘wavselectA/B’ controls the playback and functions in the same way as ‘movselectA/B’
In my installation this patch is running on two computers which are networked together, it thus creates almost perfect synchronizing between the 4 channels of video featured on the outer two screens. Thanks to Ed Kelly for help setting up the network and also giving me his timeseed and dsp_meter patches which I have also utilized.
