Nvidia to Open MDL SDK Source Code

As reported, this set of tools integrates the precise look and feel of real-world materials into rendering applications
15 August 2018   420

NVIDIA opened the source code of the Material Definition Language SDK. This tool kit is designed for transferring material parameters to any application for drawing 3D graphics. The tools will allow developers to use more applications for rendering and transfer projects to the Android and iOS platforms.

As an example, the company introduced fabric materials created in Allegorithmic Substance Designer. They can be saved in the library and quickly transferred to the Adobe Dimension CC application. The tools were also introduced into Unreal Studio 4.20 from Epic Games, designed to import 3D models into the Unreal Engine.

Being able to use a single material definition, like NVIDIA’s MDL, across multiple applications and render engines is a huge benefit to the end-user. Now that we’ve added MDL support to Unreal Studio, our enterprise customers can see their material representations converted to real time in Unreal Engine without baking every parameter. This means their creative intent can be carried to new forms of expression.

The tool kit also contains components for loading, checking and editing material parameters and converting them into PTX and LLVM-IR formats. Get more info at GitHub

Cloudflare to Develop IPFS Gateway

According to the developers, new gateway will allow to create P2P based websites

Cloudflare told about the IPFS gateway, which will allow creating sites based on P2P network. The company said that access to content will be done without having to install special software on the devices.

As a technology feature, Cloudflare experts note decentralization. Using a standard network scheme with servers involves physical storage of data in one place. Hacking the server or damage to communications as a result of an emergency (for example, a natural disaster) will lead to inaccessibility of information or its loss. The same is threatened with information if the server owner has decided to refuse it.

The IPFS gateway combines computers, on each of which some information is stored, to the worldwide network. Therefore, the inaccessibility of one computer does not mean that the content can not be viewed or downloaded. Therefore, the key differences are two:

  1. With IPFS, anyone can freely post information instead of storing it on remote servers and paying for their services.
  2. Requests for access to data are carried out using cryptographic hashing, rather than by IP address. The query data is converted to a series of letters and numbers, by which the system finds the required files. For example, the query for any information will not like "get information that is located at IP address 93.184.216.34", but the kind "get information with hash sum QmXnnyufdzAWL5CqZ2RnSNgPbvCc1ALT73s6epPrRnZ1Xy". This hash sum is part of the desired file and is on several computers.

The system automatically determines the authenticity of the file. If we take as an example a query with a hash sum QmXnnyufdzAWL5CqZ2RnSNgPbvCc1ALT73s6epPrRnZ1Xy, then when receiving the information it should remain the same. If the hash value differs, then the file has been changed. In other words, the hash-sum can be represented as a unique fingerprint:

Supporters of decentralization are also in a number of other companies. Mozilla employees believe that consumers should not be tied to a particular product, brand or platform. In early August 2018, developers published a version of the IoT gateway Things Gateway 0.5. In it, they realized the possibility of loading third-party icons and an interface for complex devices.
