This is a proof of concept hair renderer that's based on a novel hybrid approach. It's capable of rendering strand-based hair geometry in real-time, even for fully simulated hair styles with over 100,000 strands. Our hybrid rendering pipeline scales in the performance/quality domain by using a rasterizer for closeup shots and a raymarcher for level of detail minification. We can render multiple hair styles at once with this hybrid technique, which has a smooth transition between the two solutions.

...

It is written 100% from scratch in Vulkan and simulates light scattering, self-shadowing and transparency in real-time with GLSL shaders and compute. We handle anti-aliasing by using a fast line coverage method. Our volumetric approximation is derived from the original geometry with a fast voxelization scheme that is used for raymarching and "direct" shading on an isosurface. We also use this volume for ambient occlusion and for more precise self-shadowing, even in the rasterized case.

        Many other usability improvements, performance improvements and bug fixes

    New pixtool features:
        New ‘launch’ options: –remote, –force11on12, –ignore11on12.  Run “pixtool –help launch” for more information.
        Added ‘take-new-timing-capture’ command.  Run “pixtool –help take-new-timing-capture” for more information.

    GPU Capture Improvements
        New event list control – can now pin columns, sort without losing hierarchy as well as general performance improvements

From fluid dynamics and weather simulation, to computational chemistry and bioinformatics, HPC applications span across many domains. Developing these applications requires a robust programming environment with highly optimized domain specific libraries.

Announced today, CUDA-X HPC is a collection of libraries, tools, compilers and APIs that helps developers solve the world’s most challenging problems. Similar to CUDA-X AI announced at GTC Silicon Valley 2019, CUDA-X HPC is built on top of CUDA, NVIDIA’s parallel computing platform and programming model. CUDA-X HPC includes highly tuned kernels essential for high-performance computing (HPC). GPU-accelerated libraries for linear algebra, parallel algorithms, signal and image processing lay the foundation for compute-intensive applications in areas such as computational physics, chemistry, molecular dynamics, and seismic exploration.

Client-side Web renderer

Light Tracer is the world's first solution for GPU accelerated, photorealistic client-side rendering inside a Web browser. At the moment, only Google Chrome and Mozilla Firefox are supported.


Physically-correct engine

It is based on a physically-correct unbiased ray tracing engine working on any graphics card – both discrete GPUs like NVIDIA/AMD and integrated GPUs like Intel (with a lower performance, of course).


Fast and efficient

Highly optimized GPU path tracing engine allows for instant feedback in the viewport while navigating 3D scenes. Interactive modifications made possible by partial acceleration structure rebuilds.

3D-Tech News Around The Web / Vulkan Dos and Don’ts
« on: June 06, 2019, 08:38:29 PM »
After its popular DX12 Do's And Don'ts, NVIDIA publishes a new Dos/Donts, this time, for Vulkan:

Quote
The increased performance potential of modern graphics APIs is coupled with a dramatically increased level of developer responsibility. Optimal use of Vulkan is not a trivial concept, especially in the context of a large engine, and information about how to maximize performance is still somewhat sparse. The following document is a compilation of wisdom from some of the Vulkan experts at NVIDIA. It is not exhaustive, and is expected to be augmented over time, but should be a useful stepping stone for developers looking to utilize Vulkan to its full potential.

Google has published a speed test to check the quality of your internet connection with Stadia.

Quote
This speed test provides a general indication of the quality of your connection, but does not guarantee playability on Stadia. Your gaming experience is dependent on a variety of factors, such as your device, internet service provider, and other bandwidth-consuming activities like downloads, file shares, and streaming.

Speed test: https://projectstream.google.com/speedtest

I did a test:
- direct connection: I got 370Mbps
Quote
Your connection is great.
Based on your current download speed of 370.426 Mbps, we expect you’ll have a high-performance gaming experience on Stadia.

- connection via Opera's VPN: I got 17Mpbs
Quote
Your connection is good.
Based on your current download speed of 17.029 Mbps, we expect you’ll be able to play in high definition on Stadia, but you might not get 4K resolution.

We show how to compute global illumination efficiently in scenes with dynamic objects and lighting. We extend classic irradiance probes to a compact encoding of the full irradiance field in a scene. First, we compute the dynamic irradiance field using an efficient GPU memory layout, geometric ray tracing, and appropriate sampling rates without down-sampling or filtering prohibitively-large spherical textures. Second, we devise a robust filtered irradiance query, using a novel visibility-aware moment-based interpolant. We experimentally validate performance and accuracy tradeoffs and show that our method of dynamic diffuse global illumination (DDGI) robustly lights scenes of varying geometric and radiometric complexity. For completeness, we demonstrate results with a state of the art glossy ray tracing term for sampling the full dynamic light field and include reference GLSL code.

Geeks3D's GPU Tools / MSI Kombustor 4 v0.8.0.0 released
« on: June 05, 2019, 09:20:22 AM »
After nearly one year without update, MSI Kombustor is back with a new version. This version adds support of recent NVIDIA and AMD GPUs, fixes bugs in the Vulkan renderer and brings two new stress tests / benchmarks. The first benchmark (MSI-01) is a pure graphics stress test (tessellation + DoF + PBR) while the second benchmark is based on PhysX 4 and allows to test either the CPU (multi-threaded simulation) or the GPU. Benchmark scores can now be submitted online.

This post is a walkthrough of the vulnerability that we discovered that allows execution of arbitrary commands on a system with the NVIDIA GeForce Experience (GFE) prior to version 3.19 installed – CVE-2019-5678. The exploit can be achieved by convincing a victim to visit a crafted web site and make a few key presses. This is possible due to command injection which was discovered in a local “Web Helper” server which GFE launches on startup.

...

MWR Labs stated in this blog post that GFE starts a local API server which allows control over different aspects of GFE. When you change a setting in the GFE GUI interface, it is likely just making a call to this local API. Knowing this, I thought it may be worthwhile to look into the API to see if there was any interesting functionality. The server that is started by GFE is NodeJS Express and many of the JavaScript source files can be found in “C:\Program Files (x86)\NVIDIA Corporation\NvNode”.

With Windows Version 1903, we have added a new toggle in Graphics Settings for variable refresh rate. Variable refresh rate (VRR) is similar to NVIDIA’s G-SYNC and VESA DisplayPort Adaptive-Sync.

This new OS support is only to augment these experiences and does not replace them. You should continue to use G-SYNC / Adaptive-Sync normally. This toggle doesn’t override any of the settings you’ve already configured in the G-SYNC or Adaptive-Sync control panels.

This new toggle enables VRR support for DX11 full-screen games that did not support VRR natively, so these games can now benefit from your VRR hardware.

Facebook Inc. said it removed 2.2 billion fake accounts in the first quarter, a record that shows how the company is battling an avalanche of bad actors trying to undermine the authenticity of the world’s largest social network.

In the final quarter of 2018, Facebook disabled just more than 1 billion fake accounts and 583 million in the first quarter of last year. The vast majority are removed within minutes of being created, the company said, so they’re not counted in Facebook’s closely watched monthly and daily active user metrics.

“The larger quantities of fake accounts are driven by spammers who are constantly trying to evade our systems,” Guy Rosen, Facebook’s vice president of integrity, told reporters Thursday.
