Realtime Animation and Rendering of Ocean Whitecaps - Picture

Realtime Animation and Rendering of Ocean Whitecaps

We present a scalable method to procedurally animate and render vast ocean scenes with whitecaps on the GPU. Our model takes advantage of the fast mip-mapping and texture filtering capabilities of modern hardware to produce plausible and anti-aliased images for scales ranging from centimetric to planetary in realtime.

A Time Series 3D Hierarchy for Real-Time Dynamic Point Cloud Interaction - Picture

A Time Series 3D Hierarchy for Real-Time Dynamic Point Cloud Interaction

Adopting point cloud representations can avoid computational complexity in connectivity construction.We propose a time series hierarchy for rendering of dynamic point-based models, using a novel spatio-temporal synchronization approach. Higher precision, efficient memory usage and responsive interaction can be delivered on desktops or mobiles in multi-view mode.

Real or Fake? Human judgments about photographs and computer-generated images of faces - Picture

Real or Fake? Human judgments about photographs and computer-generated images of faces

Our work explores what factors influence whether people perceive an image to be a real photograph or a computer-generated image of faces. The main goal is to characterize aspects of images and humans on the perception of visual realism for face images.

A 2.5D Culling for Forward+ - Picture

A 2.5D Culling for Forward+

We present a 2.5D culling for Forward+ which is simple and inexpensive, but effective. The method culls lights that falls in the void space between the foreground and background geometry. It can be implemented by adding a few ALU instructions to the Forward+ rendering pipeline.

Stroke-based Real-time Ink Wash Painting Style Rendering for 3D Models - Picture

Stroke-based Real-time Ink Wash Painting Style Rendering for 3D Models

In this paper, we present an approach to generate ink wash painting
styled images for 3D model. It is an stroke-based method with flexible ink simulation by analyzing the baisc drawing techniques in ink wash painting, which is suitable for NPR on complex objects.
