To convert coordinates of an object from 3D to 2D space (to get the 2D projection of a 3D point), you need a [[Eyeon:Manual/Fusion_6/Camera_3D|Camera3D]] and a [[Eyeon:Manual/Fusion_6/Locator_3D|Locator3D]].

1. If the camera was created not in Fusion, import the camera parameters into the [[Eyeon:Manual/Fusion_6/Camera_3D|Camera3D]] node pressing '''"Import Camera..."''' in its Controls tab. Fusion supports the following formats: Maya ASCII (.ma), XSI Scene (.xsi), 3Ds Max (.ase), Lightwave (.lws)<br>
2. If the 3D object is animated in Fusion, create a [[Eyeon:Manual/Fusion_6/Locator_3D|Locator3D]] node and connect it's coordinates to the object: RMB on the X/Y/Z Offset, select '''Connect To''' and choose the animated X/Y/Z parameters.<br>
2.1. If the object was animated in another application, export its coordinates from the application as a locator into one of the formats listed above, then create a [[Eyeon:Manual/Fusion_6/Locator_3D|Locator3D]] node and press the '''"Import Transform..."''' button in its 3D Controls tab to import the animation from the external file.<br>
2.2. If you want to get coordinates from a point cloud generated by tracking software, create a [[Eyeon:Manual/Fusion_6/Point_Cloud_3D|PointCloud3D]] node press '''"Import Point Cloud..."''' in the Controls tab to import it from an external file (the same format list). Then create a [[Eyeon:Manual/Fusion_6/Locator_3D|Locator3D]]. You can position the [[Eyeon:Manual/Fusion_6/Locator_3D|Locator3D]] according to the point cloud in three ways:<br>
2.2.1. Select a point of the [[Eyeon:Manual/Fusion_6/Point_Cloud_3D|PointCloud3D]] in the [[Eyeon:Manual/Fusion_6/Display_Views/Display_View_Introduction|Display View]], RMB in the window, select '''PointCloud3D>Publish'''. Then copy the coordinates of the newly published point to the corresponding [[Eyeon:Manual/Fusion_6/Locator_3D|Locator3D]] coordinates.<br>
2.2.2. Display the [[Eyeon:Manual/Fusion_6/Point_Cloud_3D|PointCloud3D]] in a [[Eyeon:Manual/Fusion_6/Display_Views/Display_View_Introduction|Display View]], select the [[Eyeon:Manual/Fusion_6/Locator_3D|Locator3D]] and use its '''"Pick Translation"''' button from the 3D Controls tab to select a point from the point cloud to which the [[Eyeon:Manual/Fusion_6/Locator_3D|Locator3D]] should stick to. This method is less precise and reliable, but it's much faster.<br>
2.2.3. Use the [[Media:SE_PointCloudFun.eyeonscript|SE_PointCloudFun]] tool script. It should be copied to your Fusion:\Scripts\Tool and then you can RMB on the [[Eyeon:Manual/Fusion_6/Point_Cloud_3D|PointCloud3D]] node, select '''Script>SE_PointCloudFun'''.<br>
3.Feed the [[Eyeon:Manual/Fusion_6/Camera_3D|Camera3D]] output to to the [[Eyeon:Manual/Fusion_6/Locator_3D|Locator3D]] 3D Data input.<br>
4. Set appropriate Camera Settings in [[Eyeon:Manual/Fusion_6/Locator_3D|Locator3D]]<br>
5. RMB on your 2d-object's Center, select '''Connect To>Locator3D>Position'''
