Research interests

Large-scale imagery

Large planar and spherical images motivate novel processing techniques.
[ streaming multigrid, distributed processing, spherical processing, multiscale continuity ]

Parallel spatial data structures

The SIMD parallelism in GPUs benefits from new efficient random-access spatial structures.
[ geometry clipmaps, perfect spatial hashing, compressed trees, factored images, vector graphics, mesh LOD ]

Texture synthesis

Given a compact texture exemplar, a parallel algorithm can efficiently generate spatially infinite deterministic content.
[ parallel controllable texture synthesis, appearance-space texture synthesis, vector field design, lapped textures ]

Geometry images (regularly sampled surfaces)

With optimized graphics pipelines, geometry might be represented using ordinary grids just like texture images.
[ geometry images, spherical parameterization and remeshing, smooth geometry images, multi-chart geometry images, geometry clipmaps ]

Progressive meshes (irregular connectivity)

Progressive meshes define a lossless, continuous-resolution representation of arbitrary meshes, and support scalable rendering, geomorphs, progressive transmission, and compression. They are exposed in the D3DX library of Microsoft DirectX 8.
[ mesh optimization, progressive meshes, progressive simplicial complexes, view-dependent refinement, ... ]

Subdivision-based multiresolution (semi-regular connectivity)

Mesh refinement based on uniform subdivision provides more structure than irregular meshes.
[ multiresolution analysis of arbitrary meshes, displaced subdivision surfaces ]

Surface parameterization (geometry texturing)

Textures map regularly sampled images onto irregular mesh geometry.
[ atlases in silhouette clipping, texture mapping progressive meshes, signal-specialized parameterization, and multi-chart geometry images ]
[ instanced charts in lapped textures, real-time fur rendering, and real-time hatching ]
[ also spherical parameterization and geometry image parameterization ]

Surface reconstruction (geometry creation)

My PhD thesis addresses automatic reconstruction of surface models from scanned 3D points.
[ surface reconstruction from unorganized points, mesh optimization, piecewise smooth surface reconstruction,
Poisson surface reconstruction, multilevel streaming for out-of-core reconstruction, multi-view stereo, parallel Poisson reconstruction ]

Some recent demos

	Cliplets: Juxtaposing still and dynamic imagery. This tool creates cinemagraphs and more general spatiotemporal compositions from ordinary handheld video. Demo
	Freeform vector graphics. Interactive authoring system that builds on thin-plate splines to enable a richer class of vector graphics. The user sketches a variety of curves and points to intuitively control color interpolation within the resulting image. (This demo runs best on a fast multicore CPU.) Demo 20111003
	Random-access vector graphics. Antialiased vector graphics rendered on arbitrary surfaces or under arbitrary deformations. We create a coarse lattice in which each cell contains a variable-length encoding of the graphics primitives that overlap it. These cell-specialized encodings are interpreted at runtime within a pixel shader. Demo 20080613
	Rendering of terrains using geometry clipmaps. Terrain rendering using a set of nested regular grids. The terrain is either incrementally decompressed from a compact in-memory representation or synthesized on the fly as a user navigates within an infinite landscape. Demo 20060328
