Say I have a cube with a number of segments. Is there maybe a pythonic way to taper it without using the the deformers ????

Hello,

I guess you speak of a parametric cube object? The only way to deform parametric objects is to use deformers. These deformers can work on the object's cache.

In contrast, polygon objects can be edited any way you like.

S_Bach, Sorry I should have said the cube is made editable :blush:

So how would I go around tapering a point object without a deformer ??

I want the cube to deform to a cone shape with a slider?? (Python)

Hello,

to edit the shape (geometry) of a polygon object you just need to change the position of it's points. To get all points of a polygon object just call GetAllPoints(). To set the position of a certain point use SetPoint(). You find some example on this in the SpherifyModifier example.

You can control such deformation with a slider, but this depends on what kind of GUI you use and what kind of plugin you are creating.

I know about "GetAllPoints" and "SetPoint" :wink:

I have got this far with a "plane object"

    obj = doc.SearchObject("Plane")
    cntrl = doc.SearchObject("Null")
    
    Scale = cntrl[c4d.ID_USERDATA,1]/100
    
    pntA = [c4d.Vector(-200, 0, -200),c4d.Vector(200, 0, -200),
                 c4d.Vector(-200, 0, -160),c4d.Vector(200, 0, -160),
                 c4d.Vector(-200, 0, -120),c4d.Vector(200, 0, -120),
                 c4d.Vector(-200, 0, -80),c4d.Vector(200, 0, -80),
                 c4d.Vector(-200, 0, -40),c4d.Vector(200, 0, -40),
                 c4d.Vector(-200, 0, 0),c4d.Vector(200, 0, 0),c4d.Vector(-200, 0, 40),
                 c4d.Vector(200, 0, 40),c4d.Vector(-200, 0, 80),c4d.Vector(200, 0, 80),
                 c4d.Vector(-200, 0, 120),c4d.Vector(200, 0, 120),c4d.Vector(-200, 0, 160),
                 c4d.Vector(200, 0, 160),c4d.Vector(-200, 0, 200),c4d.Vector(200, 0, 200)]
    
    pntsC = len(pntA)
    
    obj.ResizeObject(pntsC) 
        
    for i in xrange(len(pntA)) :
                
        new_x = (i * pntA[i].x) / (pntsC-1) * Scale
          
        obj.SetPoint(i,c4d.Vector(new_x,pntA[i].y,pntA[i].z))

Hello,

so, what exactly is your question?

My question is still the same. This script is for a flat "Plane Object"

How would I do it if it is a "Cube Object"

:confused:

Hello,

if your code works for a specific case you should generalize your algorithm so it can handle different cases. With a polygon object you can never now which shape is has (if it's a cube or something different).
