Internships, Ph.D. and post-doc

I am always looking for good motivated students. If you want to do a post-doc with me or a Ph.D. (or an intership) under my supervision, have a look at these. Then feel free to contact me do discuss the different opportunities.

Sketch-Based Implicit Blending by Baptiste Angles et al., Transactions on Graphics, proc. of Siggraph Asia 2017.

Watch these !

Sketch-based implicit composition: We introduce new gradient-based composition operator for combining implicit surfaces. The free-form shape linking the combined objects is inferred from a user sketches (Siggraph Asia 2017).

by Baptiste Angles et al. (see also STORM's YouTube Channel).

Constrained Color Palettes: We introduce constrained color palettes, a useful and powerful representation for color palette creation/editing by interpolation and exploration (Siggraph 2017).

by Nicolas Mellado et al. (see also STORM's YouTube Channel).

n-Ary Composition for Fluid Simulation: We handle complex field function compositions with controlled and dissymmetric blending behaviors. We apply these graph-based new operators on point-based fluid simulations for accurately controlling the fluid surface at boundaries (Symposium on Computer Animation 2016).

by Florian Canezin et al. (see also STORM's YouTube Channel).

Elastic Implicit Skinning: We extend the implicit skinning technique with a tangential relaxation scheme derived from the ARAP energy for controlling the mesh elasticity during an animation (Siggraph Asia 2014).

by Rodolphe Vaillant et al. (see also STORM's YouTube Channel).
