Abstract
This case study stages a controlled conflict between image coherence and spatial truth. From one privileged viewpoint, the footage reads as a stable 2D scene. As the viewpoint shifts, the same footage becomes evidence of a 3D volume—splitting across faces and exposing the mechanism that previously remained invisible. The system treats the camera not as a neutral observer, but as a switch that determines what counts as “the image.”
Research Question
When does a moving image behave like a surface, and when does it reveal itself as a projection distributed across space?
More specifically: How much viewpoint change does it take for an image to stop being believed as a continuous record and become read as a constructed object?
System / Method
A source video is mapped orthographically onto a 3D proxy structure (a hidden volume).
The camera performs a controlled rotational sweep around the proxy.
As the view departs from the privileged axis, projection continuity breaks:
- the footage fragments across multiple planes,
- spatial discontinuities become legible,
- the proxy reads as “the cause” of the image.
At approximately 90°, the proxy becomes visually minimized and the video reconstructs into a coherent image plane.
Observations
- Coherence is viewpoint-dependent: continuity is not an inherent property of the video, but an alignment event.
- The reveal is procedural, not decorative: the fracture pattern communicates underlying geometry and mapping logic.
- Reconstruction behaves like a perceptual snap: at the correct alignment, the viewer’s attention shifts from “object” back to “image.”
Key Contributions
- Demonstrates a compact, readable system where camera motion functions as an epistemic test: it determines whether the viewer interprets content as documentation or construction.
- Bridges cinematic language (the sweep/reveal) with computational imaging logic (projection, proxy geometry, alignment).
- Produces a repeatable template for future studies using different source footage, proxy topologies, and sweep ranges.
Why this belongs in Computational Imaging
Although the source material is aerial/urban footage, the project’s subject is image formation under constraint: how projection and viewpoint produce (or destroy) continuity, and how spatial proxies can “carry” an image until the view reveals the cheat.
Tools
- Cinema4D for proxy modeling + UV/projection setup, orthographic projection mapping, and rendered camera sweep.
- AfterEffects used for editing, pacing, and presentation.
Next Iterations
- Test different proxy geometries to control how the fracture reads (grid, radial, architectural proxies).
- Quantify the “break point” (angle threshold) where viewers stop reading the image as continuous.
- Add a split-screen diagnostic render (clean view / proxy-only / UV/projection debug) for tighter research documentation.
