Dot Vector in Python ?

[MrScienceOfficer]

Outside of the formatting issue, it looks fine.

Your error isn't related to that code(unless its related to the formatting issue)

[CinnamonMetal]

Sorry, can you point out the formatting issue ?

The section entitled "Few Important Things to Remember" at the end, briefly goes that.

 

I recommend going through other tutorials I found here,

I know that; what I can't figure out is the error.  I get an error related to hou.py in the python library.

[MrScienceOfficer]

I recommend posting an example file showing the issue like Bonsak suggested.

def theLooper(curNode):
    for thePrim in curNode.geometry().prims():
        primColor = thePrim.floatListAttribValue("Cd")
        rounded = tuple((round(total,3)) for total in primColor)
        print(thePrim.number())
        print(primColor)
        print("Theese are the rounded numbers\n"+str(rounded))
        #print(round(primColor,3))
        dot = hou.Vector3(primColor).dot(hou.Vector3((rounded))
        tolerance = 0.000001
        if dot >= 1.0-tolerance and dot <=1.0+tolerance:
            print("match")
        else:
            print("no match")
    if curNode.geometry().findPrimAttrib("Cd"):
        print("yes")
    else:
        print("no")

The error is at the `tolerance` variable ?

def theLooper(curNode):
    for thePrim in curNode.geometry().prims():
        primColor = thePrim.floatListAttribValue("Cd")
        rounded = tuple((round(total,3)) for total in primColor)
        print(thePrim.number())
        print(primColor)
        print("Theese are the rounded numbers\n"+str(rounded))
        #print(round(primColor,3))
        dot = hou.Vector3(primColor).dot(hou.Vector3((rounded))) # closing parentheses was missing
        tolerance = 0.000001
        if dot >= 1.0-tolerance and dot <=1.0+tolerance:
            print("match")
        else:
            print("no match")
    if curNode.geometry().findPrimAttrib("Cd"):
        print("yes")
    else:
        print("no")

 

Python tends to throw a syntax error on the following line when a line doesn't complete it's statement i.e. parentheses block not closed.

[bonsak]

You are missing a closing parenthesis at the end of dot = hou.Vector3(primColor).dot(hou.Vector3((rounded)))

Too late

Common I missed that. 

I suppose my truncated rounded variable is not working as I thought, if it was the results should be match  

Since one values gives me a valid float color value; any suggestions on how I can get Houdini to test if the truncated float color value is equal to that of the full float color value ?

Why would it match (and why would you need it to?), your rounding to the .001th decimal place and testing for a tolerance to .00001th place.
