Aligning Objects

Hello,

Couldn't find this in the manual - maybe I've missed something obvious. But is there a way to align 3D objects on a particular axis? Or to centre objects relative to others?

Hi,

Please copy paste an example comp of what you are trying to accomplish.

Cheers,

Marc

For example, I want to centre the X & Y of the camera with the 3DShape.

Code: Select all

{
   Tools = ordered() {
      Shape3D1 = Shape3D {
         CtrlWZoom = false,
         Inputs = {
            ["Transform3DOp.Translate.X"] = Input { Value = 0.523223474893334, },
            ["Transform3DOp.Translate.Y"] = Input { Value = -0.503418802189864, },
            ["MtlStdInputs.MaterialID"] = Input { Value = 2, },
            ["SurfacePlaneInputs.ObjectID.ObjectID"] = Input { Value = 2, }
         },
         ViewInfo = OperatorInfo { Pos = { 1265, 247.5 } },
      },
      Merge3D1 = Merge3D {
         Inputs = {
            SceneInput1 = Input {
               SourceOp = "Camera3D1",
               Source = "Output",
            },
            SceneInput2 = Input {
               SourceOp = "Shape3D1",
               Source = "Output",
            },
         },
         ViewInfo = OperatorInfo { Pos = { 1210, 379.5 } },
         Colors = {
            TileColor = { R = 0.525490196078431, G = 0, B = 0.00784313725490196 },
            TextColor = { R = 0, G = 0, B = 0 },
         }
      },
      Camera3D1 = Camera3D {
         Inputs = {
            ["Transform3DOp.Translate.X"] = Input { Value = -0.801984826056138, },
            ["Transform3DOp.Translate.Z"] = Input { Value = 1.0678535408965, },
            AoV = Input { Value = 19.2642683071402, },
            ["Stereo.Mode"] = Input { Value = FuID { "Mono" }, },
            FilmGate = Input { Value = FuID { "BMD_URSA_4K_16x9" }, },
            ApertureW = Input { Value = 0.831496062992126, },
            ApertureH = Input { Value = 0.467716535433071, },
            ["SurfacePlaneInputs.ObjectID.ObjectID"] = Input { Value = 1, },
            ["MtlStdInputs.MaterialID"] = Input { Value = 1, },
         },
         ViewInfo = OperatorInfo { Pos = { 1100, 247.5 } },
         Colors = {
            TileColor = { R = 0.525490196078431, G = 0, B = 0.00784313725490196 },
            TextColor = { R = 0, G = 0, B = 0 },
         }
      }
   }
}

OK, I see the comp, silly question probably, but why not just set the xyz of both to 0 and move around the merge xyz.. then camera is centered on shape and locked together ...?

Yeah, could do. I was just hoping for a quick and easy way to align one object to another (like in Maya/Afx) on a particular axis as I often want to centre the camera or it's target on another object.

Perhaps there isn't a way other than typing in the values like you say.

With some scripting it should doable

You can open both camera and shape, then on the coords tab set camera target enabled, then right click xyz and set to expression, then pickwhip to the xyz of the shape..

            TextColor = { R = 0, G = 0, B = 0 },
         }
      }
   }
}

Hmmm. I wonder if a script or macro could be setup then to automate that...

Anyway - many thanks.
