Form grid not perfect

[Roland R. kahlenberg]

What are you intending to do with the grid or with the objects in the grid? There are other options to creating a grid.

[Chris McCard] “Heres my setup, I have 2 layers each with form on them

one of them is

10000px X 10000px with 500×500 particles

and the other is

2000px X 2000px with 100×100 particles –

the math all seems right to me and it should be lining up on top of eachother, but its not.”

The spacing of the grid is what’s causing this. The particles at the edges of the grid will have their centers located at the boundary of the grid. To account for this you can modify your grid sizes.

Simply take the value you currently have and subtract Particle Size * 2 from both the large and small grids, so if you had a particle of size 10:

2000 – (2 * 10) = 1980
10000 – (2 * 10) = 9980

Those sizes will cause the particles to line up entirely inside of a 2000×2000 and a 10000×10000 grid instead of the outer particles sitting half inside and half outside those boundaries.

Darby’s likely got the math correct but my thoughts are that you could easily have duplicated the larger layer and then applied a track matte to delimit its effective size.

This works great! thanks for your help. i was sorta eyeballing it before hand but the math really helps on this. Thanks so much!

Yea, ive experimented with a few other ways of making grids, however the form way is how i decided to go as I’m going to be flying around this grid a bit- and the smaller grids that are inside of that I’m using for pattern generators to effect the color/opacity of only whats inside that area. There may be better ways to do this, but form was my first setup on it and i thought it would work best.
