Vectorization research code designed for structured low-resolution clip-art. Works by first computing a perceptually optimal polygonal approximation through a shortest cycle formulation on the raster boundary. This approximation is used to guide the curve fitting and model the supervised primitive classification.

Implementation of surface subdivision schemes for triangular (Loop) and quadrilateral (Catmull-Clark) manifold meshes. Experimenting with SoA layouts and SIMD intrinsics.

Code

Unidirectional Monte Carlo path tracer supporting textures, multiple importance sampling, BSDFS (Lambertian, specular, glass) and multi-threaded rendering.

Github

Forward renderer supporting many lights through screen-space buckets, HDR pipeline with luminosity downsampling and tone mapping, shadows with PCF filtering.

Github

Implementation of Motion Graphs [Kovar et al '02]. Capable of loading a BVH motion sequence, correctly rendering it, identify similar motion segments and generate keyframes smoothly interpolating the two segment endpoints.
(The download is big as it includes part of the BVH CMU dataset)

Code

Finds the minimizer of a quadratic function subject to equality and inequality constraints: Newton's method is applied to the KKT conditions to obtain a search direction which is then refined through Mehrotra predictor-corrector logic. I apply it to the relatively simple retargeting problem used in my BSc thesis.

Code Course report

Stores sparse and compact retargeting solutions as EXIF metadata in JPEG images. A client-side scripts extracts the metadata replacing the image with a WebGL canvas which interpolates the closest solutions to retarget the image to the desired resolution (inferred from its style).
