very cool thanks

hey thanks for the answer

but its not totally what i meant

if I had to reformulate it now i would have asked for a function which scans the previous one and creates a random pair of legs "on top" of the other and places it without intersections ans rescans the newly created one again and again .

the basic "idea" of the sketch was how i wanted it
but the lines were too chaotic

i hope my text is not too incomprehensible

regards David

Hi its me again with another problem

newPage(2000, 2000)
xMiddle = 2000/2
yMiddle = 2000/2
strokeWidht=2


g1=randint (20,100)
g2=randint (500,900)
g3=randint (20,100)
g4=randint (20,100)
g5=randint (20,100)


w=1
h=1
def legs (x,y,w,h):
       
    scale(w, h)
    newPath()
    stroke(0)
    fill(None)
    strokeWidth(strokeWidht)
    polygon ((0,0),(g2,0),(g2,-g3),(g4,-g5),(g1,-g2),close=False)

def legs2 (x,y,w,h):
       
    scale(w, h)
    newPath()
    stroke(0)
    fill(None)
    strokeWidth(strokeWidht)
    polygon ((0,0),(-g2,0),(-g2,-g3),(-g4,-g5),(-g1,-g2),close=False)
    
# def wing (x,y):
#     newPath()
#     stroke(None)
#     fill(0,0,20, 0.5)
#     blendMode('exclusion')
#     strokeWidth(strokeWidht)
#     polygon ((0,29),(g2,g5),(g2,-g3),(g4,-g5),(g1,-g2),close=True)
    
    
   




translate(xMiddle,yMiddle)
rect(-20,-3,40,40)
# wing(0,0)

for i in range(4):
 
    g1=randint (20,100)
    g2=randint (20,644)
    g3=randint (20,100)
    g4=randint (20,100)
    g5=randint (20,100)

           
    
    
    
    
    translate (0,+i+5)
    

    legs(0,0,w,h)
    legs2(-0,-0,w,h)
    

I wrote this code which generates "legs "randomly
now Iam looking to generate these randomly without them intersecting each others

Maybe one of you have a little hint for me

Greetings David

thanks

@gferreira said in determine centerpoint in irregular rectangle / create "composition":

def myShape(x, y, w, h):
save()
translate(x, y)
scale(w, h)
newPath()
moveTo((0., 0.0))
lineTo((1.0, 0.0))
curveTo((0.7, 0.3), (0.7, 0.7), (1.0, 1.0))
lineTo((0, 1.0))
closePath()
drawPath()
restore()

newPage(500, 500)

xMiddle = width()/2
yMiddle = height()/2

shapeWidth, shapeHeight = 354, 242

shapeX = xMiddle - shapeWidth/2
shapeY = yMiddle - shapeHeight/2

myShape(shapeX, shapeY, shapeWidth, shapeHeight)

Thanks Mister Ferreira
for your quick and detailed answer

can I ask you why suddenly everything is now in decimal numbers ?
this is the only thing i didnt really understand

Best regards David

Hi Iam still learning the basics and i have a new problem !

I drew a rectangle using lineTo commands and curveTo commands
and I managed to center it but I wanted to ask if there is a way to treat the 4 commands more like a group or rect without loosing the ability to control the handles.

the only solution i found was to return a distance value for each point

thanks a lot

regards david

for i in range(1) :
    newPage (5000,5000)
    xMiddle, yMiddle = 2500, 2500  # mitte

    fill(0)

    for i in range(1): #Body
        translate (-450,450)

        newPath()

        moveTo((-0, -0))
        # line to from the previous point to a new point

        # close the path
        closePath()

        drawPath()

Cool thanks for your help !
Iam really struggling to find the right information in the reference

Hi Community
I would wish that every shape in the loop is unique and not repeated

is that somehow possible ?

Hi

I think I have a easy to solve problem

can somebody tell me how to center an anchor point to the "ovals" middle ?

and is there a trick to move a primitive itself to the middle of the canvas ?

I appreciate every help

thank you
