Through-the-Lens Scene Design

The increasing need in composing nice views of 3D scenes make it necessary to propose better editing tools that emphasize composition and aesthetics through high-level manipulators. In this paper, we propose to relieve the user from some low-level aspects of manipulation using a Through-the-lens declarative scheme. The projected features of the components that guide the composition of a picture (staging, camera and settings) are considered as primitives on which constraints can be applied. Specifically, we show how to compute the locations and orientations of objects, cameras and lights by constraining such features as vertex positions, specular reflections, shadows and penumbra.
