Depth-Presorted Triangle Lists - Picture

Depth-Presorted Triangle Lists

We present a novel approach for real-time rendering of static 3D models front-to-back or back-to-front relative to any view direction. The approach renders depth-sorted triangles using a single draw call. Applications include order-independent transparency and overdraw elimination.

Softshell: Dynamic Scheduling on GPUs - Picture

Softshell: Dynamic Scheduling on GPUs

We present Softshell, a novel execution model for GPUs, featuring dynamic work generation on the GPU, a three-tier dynamic scheduler supporting real-time scheduling, and the ability to influence work already submitted for parallel execution. Using Softshell, algorithms with a relatively low local degree of parallelism can execute efficiently.

High-Quality Curve Rendering using Line Sampled Visibility - Picture

High-Quality Curve Rendering using Line Sampled Visibility

Computing accurate visibility for thin primitives, such as hair strands, fur, grass, at all scales remains difficult or expensive. We present an efficient visibility algorithm based on spatial line sampling, and a novel intersection algorithm between line sample planes and Bézier splines with varying thickness.

Axis-Aligned Filtering for Interactive Sampled Soft Shadows - Picture

Axis-Aligned Filtering for Interactive Sampled Soft Shadows

We develop an efficient method for soft shadows from planar area light sources, based on raytracing, followed by adaptive image-space filtering. Our technical approach derives from recent work on frequency analysis and sheared 4D filtering for offline soft shadows. We develop the theoretical analysis to consider axis-aligned filtering.

Foveated 3D Graphics

Human vision is sharper in the center than in the periphery. Our system tracks the user's gaze and renders the just the area around the gaze point at high resolution. The result appears to be full resolution to the user but is 5-6 times faster to compute.
