Camera Projection vs. Projection 3D Node
The Camera 3D node also provides a projection feature, and should be used when the
projection is meant to match a camera, as this node has more control over aperture, film back,
and clip planes. The Projector 3D node was designed to be used as a custom light in 3D scenes
for layering and texturing. The projector provides better control over light intensity, color, decay,
and shadows.
Inputs
The Projector 3D has two inputs: one for the scene you are projecting on to and another for the
projected image.
–
SceneInput: The orange scene input accepts a 3D scene. If a scene is connected
to this input, then transformations applied to the spotlight also affect the rest of the
scene.
–
ProjectiveImage: The white input expects a 2D image to be used for the projection.
This connection is required.
Basic Node Setup
As an example, the Projector 3D node below is used to project a texture (MediaIn2) onto 3D
primitives as a way to create a simple 3D set. All the set elements are connected into a Merge
3D, which outputs the projected set into a larger scene with camera, lights, and other elements.
As an alternative, the Projector 3D node could be inserted between the two Merge 3D nodes;
however, the transform controls in the Projector 3D node would then affect the entire scene.
