3D-Tech News Around The Web / Direct3D 12 render passes
« on: November 19, 2018, 10:57:38 AM »

The render passes feature is new for Windows 10, version 1809 (10.0; Build 17763), and it introduces the concept of a Direct3D 12 render pass. A render pass consists of a subset of the commands that you record into a command list.

To declare where each render pass begins and ends, you nest the commands belonging to that pass inside calls to ID3D12GraphicsCommandList4::BeginRenderPass and EndRenderPass. Consequently, any command list contains zero, one, or more render passes.

3D-Tech News Around The Web / AMD Discloses Initial Zen 2 Details
« on: November 19, 2018, 10:54:28 AM »
Zen 2 is  AMD's next-generation core microarchitecture for desktop and server chips.
Some numbers: 7nm TSMC, up to 64 cores and 128 threads!

Quote
Earlier this month AMD made their first disclosure of Zen 2, their next-generation core microarchitecture for desktop and server chips. Along with Zen 2, AMD also unveiled initial details of their next-generation server chips, codename Rome.

...

Zen 2 succeeds Zen/Zen+. The design targets TSMC 7 nm process node. AMD evaluated both 10 nm and 7 nm. The choice to go with 7 nm boiled down to the much lower power and higher density they were able get. AMD claims 7-nanometers delivers 2x the density and offers 0.5x the power at the same performance or >1.25x the performance at the same power (note that at Computex AMD’s slide said “1.35x”). Zen 2-based chips are currently sampling and are on track to be delivered to market in 2019.

...

With eight octa-core compute dies, Rome can offer up to 64 cores and 128 threads, effectively doubling/quadrupling (AVX2) the throughput of first-generation EPYC. Although Rome stays with 128 PCIe lanes, it brings new supports for PCIe Gen 4, doubling the transfer rate from 8 GT/s to 16 GT/s. There are eight DDR4 memory channels supporting up to four terabytes of DRAM per socket. One interesting detail AMD disclosed with their GPU announcement is that the infinity fabric now supports 100 GB/s (BiDir) per link.

hardwareluxx.de and techpowerup.com have tested the freshly released Battlefiled 5 with realtime raytracing effects (DX12 + DXR). The conclusion is simple: the performance drop is enormous! What's more the raytracing is limited to reflective surfaces only (water, mirrors, glasses), shadows for example are not raytraced. In 4K, BF5 with DXR is not playable on a RTX 2080/Ti.

NVIDIA today introduced the Quadro RTX 4000 graphics card — the company’s first midrange professional GPU powered by the NVIDIA Turing architecture and the NVIDIA RTX platform.

Unveiled at the annual Autodesk University Conference in Las Vegas, the Quadro RTX 4000 puts real-time ray tracing within reach of a wider range of developers, designers and artists worldwide.

Professionals from the manufacturing, architecture, engineering and media creation industries witnessed a seismic shift in computer graphics with the launch of Turing in August. The field’s greatest leap since the invention of the CUDA GPU in 2006, Turing features new RT Cores to accelerate ray tracing and next-gen Tensor Cores for AI inferencing which, together for the first time, make real-time ray tracing possible.

The Quadro RTX 4000 features a power-efficient, single-slot design that fits in variety of workstation chassis.

3D-Tech News Around The Web / 2Geom: easy C++ 2D graphics library
« on: November 12, 2018, 05:25:26 PM »

What is this?
2Geom is a C++ 2D geometry library geared towards robust processing of computational geometry data associated with vector graphics. The primary design consideration is ease of use and clarity. It is dual-licensed under LGPL 2.1 and MPL 1.1.

The library is descended from a set of geometric routines present in Inkscape, a vector graphics editor based around the Scalable Vector Graphics format, the most widespread vector graphics interchange format on the Web and a W3C Recommendation. Due to this legacy, not all parts of the API form a coherent whole (yet).

Rendering is outside the scope of this library, and it is assumed something like libcairo or similar is employed for this. 2geom concentrates on higher level algorithms and geometric computations.

Features List
    C++
    Functional programming style.
    Points
    Efficient affine transformations
    Rectangles
    Convex Hulls
    Bounded error
    General purpose paths:
        Exact elliptical arcs
        Area
        Centroid and bending moments
    Path Locations:
        Determination of special spots (e.g. maximum curvature)
        Splitting
        Point, tangent, curvature at location
        Efficient arc length and inverse arc length
    Path algebra:
        Computations such as offset curves can be written with their mathematical definition and still get a bounded error,
        efficient curve. (preliminary trials indicate offset done this way out performs the method used in Inkscape)
    Arbitrary distortion (with bounded error):
        Mesh distorts
        Computational distorts such as the GIMP's 'vortex' plugin
        3d mapping (perspective, flag, sphere)
    Exact boolean ops (elliptic arcs remain elliptic arcs)
    Efficient 2d database
    Implicit function plotting
    NURBs input and output
    Tunable path simplification
    PDoF constraint system for CAD/CAGD

This project is a very basic unidirectional path tracer that I wrote using DirectX Raytracing, also known as DXR. I mostly did this to learn the new API, and also for a bit of fun. Therefore you shouldn't take this as an example of the best or most performant way to implement a path tracer on the GPU: I mostly did whatever was fastest and/or easiest to implement! However it could be useful for other people looking for samples that are bit more complex than what's currently offered in the offical DirectX sample repo, or for people who want to start hacking on something and don't want to do all of the boring work themselves. Either way, have fun!

3D-Tech News Around The Web / NVIDIA GeForce RTX 2080 Ti are dying!

- Nvidia RTX 2080 Ti Cards Have A Serious Problem -- They Keep Dying
Quote
I just finished reading a surprisingly large quantity of forum posts and complaints -- at least the ones I'm aware of -- from owners of Nvidia's new flagship RTX graphics cards. They all can be condensed into a single broad statement: the RTX 2080 Ti sure seems to be dying on a lot of people, resulting in some seriously unhappy early adopters. Literally hundreds of them. And this card just launched one month ago.


- Nvidia's GeForce RTX 2080 Ti cards are reportedly failing in high numbers

Founders Edition cards seem to be the most bork-prone

SO YOU'VE DROPPED NORTH OF A GRAND on Nvidia's RTX 2080 Ti; not only do you expect all the graphics, but you also don't expect it to fail.

But rather worryingly, Nvidia's flagship GPU is failing more often than it should, according to Digital Trends, which reported graphical artefacts and instabilities right after installing the graphics card.

And elsewhere, rather high numbers of other RTX 2080 Ti users are flagging that their cards are failing very quickly.

The 'Founders Edition' RTX 2080 Ti appears to be the card that's most likely to fail, with reports that even replacements from manufacturers are also borking.

These cards are also failing despite the fact that they are locked down and don't allow users to carry out manual overclocking or change the voltage, thereby meaning users can go around borking the high-end GPU.

Nvidia told us it's looking into the issue, but seemed to downplay the borkage somewhat: "We are working with users individually, but we are not seeing any broader issues."

It would look like the issue is perhaps a fault in the early production of the RTX 2080 Ti, and something Nvidia should be able to iron out, though it'll probably cost the company a pretty penny.

Concerns are mounting over the failure rate of Nvidia’s RTX 2080 Ti graphics card, with increasing numbers of reports of dead and dying cards from early adopters. Some display issues involve artifacting and instability immediately after being installed, while others begin to show signs of degradation after a few days, despite a lack of manual overclocking or voltage manipulation.

RTX is NVIDIA’s new platform for hybrid rendering, allowing the combination of rasterization and compute-based techniques with hardware-accelerated ray tracing and deep learning. It has already been adopted in a number of games and engines. Based on those experiences, this blog aims to give the reader an insight into how RTX ray tracing is best integrated into real-time applications today. This blog assumes that the reader is familiar with the Microsoft DXR API at a basic level.

While ray tracing can produce much more realistic imagery than rasterization, it is also computationally intensive. The best approach for real-time applications is hybrid rendering, a combination of ray tracing and rasterization. Rasterization is used where it is most effective while ray tracing is used where it provides the most visual benefit compared to rasterization. The typical use cases for ray tracing include reflections, diffuse global illumination, shadows, and ambient occlusion while primary visibility is resolved through rasterization as before. Another potential use case for RTX is to implement a more complete path tracer for non-real-time light map baking or for use as a reference in content production and development of less accurate real-time techniques.

A barebones application to get you jump started with DirectX Raytracing (DXR)! Unlike other tutorials, this sample code does not create or use any abstractions on top of the DXR Host API, and focuses on highlighting exactly what is new and different with DXR using the raw API calls.

To compile the demo you need VS2017 and the Windows 10 SDK v10.0.17763.0. And to run the demo you need a GPU that support D3D12_RAYTRACING_TIER_1_0. In other words, a GeForce RTX  :P
