Camera projections

PostSat Nov 14, 2015 9:47 pm

Hello,

Can anyone please present the proper way of setting up a camera projection. I was trying to do it with a Camera3D as a projector and with Projector3D nodes, without any result. I want to project an image on a loaded custom geometry - not on a plane.

Thank you,
Lukas

Here's a really simple example of using projection mapping with an ambient light. You can copy the code and paste in the Fusion flow. You'll just have to replace the loader in this flow with something you have locally.

Code: Select all
{
   Tools = ordered() {
      aniCam = Camera3D {
         CtrlWZoom = false,
         NameSet = true,
         Inputs = {
            ["Transform3DOp.Translate.X"] = Input { Value = -4.7676106345563, },
            ["Transform3DOp.Translate.Z"] = Input { Value = 6.40997375086043, },
            ["Transform3DOp.Rotate.Y"] = Input { Value = -29.1084695649333, },
            AoV = Input { Value = 24.3265863475745, },
            ["Stereo.Mode"] = Input { Value = FuID { "OffAxis", }, },
            ["SurfacePlaneInputs.ObjectID.ObjectID"] = Input { Value = 3, },
            ["MtlStdInputs.MaterialID"] = Input { Value = 3, },
         },
         ViewInfo = OperatorInfo { Pos = { 957.016, 195.926, }, },
      },
      Note1 = Note {
         Inputs = {
            Comments = Input { Value = "Replace this loader with a texture\r\n", },
         },
         ViewInfo = StickyNoteInfo {
            Pos = { 349.455, -42.2308, },
            Flags = {
               Expanded = true,
            },
            Size = { 196, 256.468, },
         },
      },
      Merge3D1 = Merge3D {

In addition to Yuri's suggestion, Alkesh has a lot of information in his Projection Mapping and re-lighting tutorials. This is a good place to start:
