Camera Mapping
Camera mapping lets you add depth and perspective to a matte painting or
rendered image by allowing it to be projected onto geometry from the point
of view of the camera. In this way, you can add the illusion of 3D movement
to a 2D scene. This facilitates the creation of virtual set extensions, and is also
used as part of the process of converting 2D material to stereoscopic imagery.
Using the Camera Mapping tool, which you can place between the geometry
generator and the Layer node, you can generate UV coordinates. UV
coordinates are 2D coordinates that you can apply to an object; they are
generated by the camera connected to the Camera Mapping tool. UV
coordinates are affected by the camera's parameters, such as the field of view,
distance, and so on.
To use the Camera Mapping tool:
1 Create a new composition.
2 From the Tools tab, select Reaction and drag it to the Schematic view
3 Select a layer type from the Layer type menu and click Create to add a
new layer.
4 Open the File browser and drag the image you want projected into
Schematic and attach it to the new layer you created.
5 Display the Group Schematic by double-clicking the Reaction node or
right-clicking the Reaction node and selecting Edit Group.
