found a cool recusive algrotim that speeds up drawing 100x*

also looks cool to boot!

#  CONTROLS

# + = make bigger  (key is actually "=")

#  - = make smaller 

# SPACE = reset

inspired by amazing video

# prompt

```python

write a javscript p5.js sketch.

creates two grid's

grid_current = a NxN arrays, (hiegnt, width),initalized to all 0 's

grid_buffer = a NxN arrays, (hiegnt, width), initalized to all 0's

create a enum {0: empty, 1: sand}

set current position to 

where height defaults to 10

      width  defaults to 10

create a function updateGridState to screen

inputs: 

grid_buffer, grid_current

for each row in grid

iterate the columns

if grid[current row+1][current column] is equal to enum "empty"

    set grid_buffer [current row][current column] to 'empty'

    # move the sand pixel down 

    set grid_buffer [current_rowrow+1][current column] to "sand"

if  cell bellow current is sand and grid to left & down is 'EMPTY'

    set left and down = SAND

    set current index to EMPTY

returns buffer grid

create a function draw_pixels

inputs: 

scale factor for pixels default to 4x size, grid

for each position in grid draw a rect of size scale factor by scale factor

set fill color to sandstone yellow

return 

create a function that sets the current mouse position mapped to which current grid location its pointed to and sets it from EMPTY to full

also set the surounding pixels in a radius of 5 to SAND

funciton draw()

set the result of updateGridState(scale factor, grid_buffer, grid_current) to current grid

draw_pixels

```

prompt v1

draw_pixels

create a edge detection kernal if the sum of the kernal detects a edge add a vertext to beginshape

if not dont do anything

DUDE THIS LOOKS AWESOME

but has error of vertex drawing order

![alt text](image-6.png)

fixed! was simple

dam this one came out looking really cool

prompt v2

draw_pixels

recusively do

start by splitting the grid into 4 quadrents test each, keep sub dividing untill box test size is 1

set call limit to 10

box test is iterate through 

if 0 is found then box test fails

    recurvivly subdivide the box 

if all are 1's then pass

    add vertex's for all 4 corners of.

looks cool by color by call depth
