Project FAQ
How do you match a digital 3D model with a real-world background photograph?
We utilize a technical workflow known as perspective matching or camera calibration. By identifying fixed physical landmarks in the original photo (such as fence posts, stable doors, or distant trees) and aligning them with corresponding points in our 3D software, we reverse-engineer the exact focal length, sensor crop, and spatial position of the photographer’s camera. This prevents any geometric distortion between the 3D object and the background.
Why was the foreground terrain reconstructed instead of using the original photo as is?
Integrating a new, large-scale structure into an existing landscape photography layout often creates spatial conflicts where the ground footprint meets the camera view. By digitally reconstructing the foreground terrain in 3D, we were able to open up the perspective, clear away visual clutter, and establish natural contact shadows and texture blending where the fabric hall meets the earth.
How do you simulate daylight passing through a fabric tent structure?
Tensile architectural fabrics do not block light completely; they exhibit a property called translucency. We replicate this in the rendering engine using sub-surface scattering (SSS) material shaders. This allows light rays from our virtual sun to pass through the canopy material, scattering the photons to create a realistic interior glow and an authentic external surface sheen that responds to ambient sky lighting.
