Elements placed/shifted wrong after import.

Hi,

I’m using a software called Structure Synth (http://structuresynth.sourceforge.net/index.php). There exists import scripts for older Blender versions, but the one that I found and want to use does something wrong when it places cube primitives.

I think there is something wrong with the translation matrix, but I can’t figure out what it is…
Maybe one of you can see the problem…

The problem looks like that:

But cubes should placed in that way:


argsIndex += 1
            transMatrix = ((float(args[argsIndex + 0]),  float(args[argsIndex + 1]),  float(args[argsIndex + 2]),  float(args[argsIndex + 12])), 
                           (float(args[argsIndex + 4]),  float(args[argsIndex + 5]),  float(args[argsIndex + 6]),  float(args[argsIndex + 13])), 
                           (float(args[argsIndex + 8]),  float(args[argsIndex + 9]),  float(args[argsIndex + 10]), float(args[argsIndex + 14])), 
                           (float(args[argsIndex + 3]),  float(args[argsIndex + 7]),  float(args[argsIndex + 11]), float(args[argsIndex + 15])))


            
            print (transMatrix)
            
            mat = mathutils.Matrix(transMatrix)
            print(mat)
            
            loc, rot, sca = mat.decompose()
             
            print(loc, rot, sca)
            loc = tuple(loc)
            sca = tuple(sca)
            rot = tuple(mat.to_euler())
            print (loc, sca, rot)
                       
            argsIndex += 16


            colR = eval(args[argsIndex])
            argsIndex += 1
            colG = eval(args[argsIndex])
            argsIndex += 1
            colB = eval(args[argsIndex])
            argsIndex += 1
            alpha = 1.0
            
            
            bpy.context.object.color = (colR, colG, colB, alpha)
            objColor = bpy.context.object.color
            create_CubeMesh('cubePrimary', objColor, loc, rot, sca)

Gegards and thx,

just a wild guess, but here’s a transposed version of the transMatrix:

argsIndex += 1
            transMatrix = ((float(args[argsIndex + 0]),  float(args[argsIndex + 4]),  float(args[argsIndex + 8]),  float(args[argsIndex + 3])), 
                           (float(args[argsIndex + 1]),  float(args[argsIndex + 5]),  float(args[argsIndex + 9]),  float(args[argsIndex + 7])), 
                           (float(args[argsIndex + 2]),  float(args[argsIndex + 6]),  float(args[argsIndex + 10]), float(args[argsIndex + 11])), 
                           (float(args[argsIndex + 12]),  float(args[argsIndex + 13]),  float(args[argsIndex + 14]), float(args[argsIndex + 15])))
