hi

whats the best way to do the following:

i want to read a still image, but not display it immediately. instead
i want to reveal blocks of it (maybe 10 x 10 pixels at a time)
scanning from left to right, top to bottom, until the complete image
is visible.

and this needs to be quite fast too.. like maybe 30ms per block.

thanks

if you feel more comfortable doing it in vvvv, have fun.
do you have some comments about that environment i’d be glad to hear.
from anyone using that also.

thanks Andreas for the report from the front.
i looked into vvvv 3 years ago when i was just starting with jitter, it
wasnt were its at now.
many of the good things has been there from the start, a testemnt to the
deep thought that went into it.

its true that jitter lacks in the multiple department, and reactivity has
always been a weakness of visual programing languages. in that department v4
lacks support for 3rd party languages like jitter with c, java, js and my
favorite jit.lua. a plus here.

i feel 4v has been born with spreads in mind while jitter is more of a tool
for single object manipulation, leaving multiple as an afterthought. as you
mentioned, geared for working in a column not in row. most of the work and
demos has a single object end-point in mind. the tutorials and cookbooks
leans more thowrds video processing and less "many abstract shapes"
aesthetics. which is quit abundant with v4 and p5(~realtime).
many times the tool draws users with similar aesthetic tastes.

as we could see with the community’s response to Andrew b. examples of
tinyVideo and latter, the demand for better spread support is here, and
right now its the work of creative patching that makes it possible. the
methods are available but hard to implement and not for the weak of heart.
I’m sure latter versions of jitter will address this.

the "live patching" issue is already around the corner with max5 new
inspektor(sic) and live debug inlets. some of this method were open to
veterans but now they will be were they should. at the forefront.

as many others, im excited about max5 (ad jitter2) and i hope for us all v4
will continue to capture hearts and prosper.

my 2cent, would love to hear more. and excuse my crappy grammar and
editing..

new and might receive revisions soon.

second paragraph should read ‘recursivity’ and not ‘reactivity’. blame the
spellchecker.
