Hi,

I want to place an Object on a given global Koordinate.

What i have is a Matrix with 16 Values like:
"1,0,0,0,0,1,0,0,0,0,1,0,0,0,5,1.439"

I read the documentation and found in the Topic "Matrix Fundamentals"
that my matix is like this:

  
      1     0     0     0      1     0     0     0   
    v0.x v1.x v2.x v3.x     0     1     0     0   
m = v0.y v1.y v2.y v3.y = 0     0     1     0   
    v0.z v1.z v2.z V3.z     0     0     1   1.439   
  

Here my question:
How can I convert my Data-Structure so, that i can write it in the command
obj.SetMg(Matrix)

here my aktual code

  
coord = LINEDATA.split(",")   
                    #print coord   
                    #print ("Datenzeile enthält " + str(len (coord)) + " Datensätze")   
                    MA1 = float(coord[0])   
                    MA2 = float(coord[1])   
                    MA3 = float(coord[2])   
                    MA4 = float(coord[3])   
                    MA5 = float(coord[4])   
                    MA6 = float(coord[5])   
                    MA7 = float(coord[6])   
                    MA8 = float(coord[7])   
                    MA9 = float(coord[8])   
                    MA10 = float(coord[9])   
                    MA11 = float(coord[10])   
                    MA12 = float(coord[11])   
                    MA13 = float(coord[12])   
                    MA14 = float(coord[13])   
                    MA15 = float(coord[14])   
                    MA16 = float(coord[15])   
                       
                    Matrix = [[MA1,MA2,MA3,MA4],[MA5,MA6,MA7,MA8],[MA9,MA10,MA11,MA12],[MA13,MA14,MA15,MA16]]   
                    print Matrix   
                       
                    #c4d.SetPoint(i,c4d.Vector(x,y,z))   
                    obj = c4d.BaseObject(c4d.Onull)        # Create new cube   
                    #obj.SetRelPos(c4d.Vector(20))           # Set position of cube   
                    obj.SetMg(Matrix)   
                    doc.InsertObject(obj)                   # Insert object in document   

Thanks a lot

Why don't you use the given function in that matrix chapter:
You only need to define v0 - offset and v1,v2,v3 - scale and rotation.

E.g. SetGlobalScale(obj, c4d.Vector(1.0, 1.0, 1.439))

SetGlobalPosition(obj, pos) # Sets the global position of obj to pos
SetGlobalRotation(obj, rot) # Sets the global rotation of obj to rot
SetGlobalScale(obj, scale)  # Sets the global scale of obj to scale

it sounds so easy
but:
how do I define v_0 (i think this is the offset
how do I define v_1
how do I define v_2
how do I define v_3
how do I define pos
how do I define rot
how do I define scale

I know it is in my linedata
here an example: "1,0,0,0,0,1,0,0,0,0,1,0,0,0,5,1.439"
But i dont know how to convert it.

Sorry for sutch stupid questions

Here is my actual code

  
for line in DATA:   
    LINEDATA = line.strip()                    #lese den Zeileninhalt ohne rechte Leerzeichen   
    if (LINEDATA.find (SUCHSTRING_DATA) != -1) :   
        l = len(SUCHSTRING_DATA)   
        LINEDATA = LINEDATA[l:]   
        LINEDATA = LINEDATA[:-4]   
        coord = LINEDATA.split(",")   
  
        print "Begin neuer Datensatz"   
          
  
        # Umwandlung in floating   
        for i in range(16) :   
            coord[i] = float(coord[i])   
            #print ("Coord", i , "= ",coord[i])   
            #print i   
            continue   
          
        print (coord)   
          
  
        # Definition der Vektoren   
        v_1 = c4d.Vector( coord[5] , coord[9] , coord[13] )   
        v_2 = c4d.Vector( coord[6] , coord[10] , coord[14] )   
        v_3 = c4d.Vector( coord[7] , coord[11] , coord[15] )   
        off = c4d.Vector(0,0,0)   
          
        print ( v_1 , v_2 , v_3, off)   
        print ()   
        print (v_1)   
        print (v_2)   
        print (v_3)   
        print (off)   
          
        mat = (v_1,v_2,v_3,off)   
          
        #c4d.SetPoint(i,c4d.Vector(x,y,z))   
        obj = c4d.BaseObject(c4d.Onull)        # Create new nullobject   
        #obj.SetRelPos(c4d.Vector(20))           # Set position of cube   
        obj.SetMg(mat)   
        doc.InsertObject(obj)                   # Insert object in document

Looks good. 
But make

mat = (v_1,v_2,v_3,off)

mat = c4d.Matrix(off, v_1, v_2, v_3)

instead.

small change, big impact.

it works.

Thanks a lot
