Presentation

In the context of computer graphics, this project aims to enhance the realism and visual richness of digital images. More precisely, our goal is to design novel representations for the creation, manipulation and efficient rendering of highly detailed 3D objects. First, the focus will be put on the representation of meso-scale geometry to find a lightweight and more controllable alternative to the classical bitmap-based displacement, normal, albedo or bidirectional reflectance textures. Then, we plan to generalize our approach to reproduce the very high-frequency effects produced by some classes of micro-scale geometry (e.g., brushed metals). Such effects are challenging to reproduce as they cannot be explicitly represented but smoothed out by classical material representations. Finally, we also plan to embed multi-scale aspects into our novel representation to enable alias-free rendering from distant viewpoints while avoiding the over-smoothing produced by current approaches.
