Uncapped Framerate
We at MachineGames are huge PC players, and all of id Software’s games have very strong PC DNA. So it’s important for us to make sure the PC version of the game is as solid as any console version. That’s why we built the game on idTech 6, which also allows for uncapped framerate – one of the features we’re most excited about.

When we started development of Wolfenstein II, the choice of graphics API for PC was a simple one. DOOM had already set the stage for what could be done with Vulkan and we wanted to take it to the next level.

Using Vulkan when developing has allowed us to utilize the power of AMD's VEGA graphics chips in ways that were not possible before, giving us fine grained control over the performance and feature set of the GPU without having to sacrifice artistic intent. Combined with the flexibility of AMD's hardware, Vulkan gives us the artistic freedom to deliver Wolfenstein without compromise.

3D-Tech News Around The Web / Flow Fields Explained
« on: October 24, 2017, 10:49:12 AM »
Maybe you’ve heard the term “flow field” and maybe you’ve seen some neat pictures or animations with the term attached. In this article, I’ll cover what a flow field is, show how to create one, and give a few examples of experimenting with them. Flow fields are also known as vector fields.

I’ll be using HTML5, JavaScript and Canvas for this article, but the concepts will apply to Processing, p5js, WebGL, or just about any other graphics programming platform. That being the case, I’m going to try to focus less on the canvas specific stuff and more on the core concepts.


3D-Tech News Around The Web / Windows 10 Fall Creators Update is there
« on: October 18, 2017, 08:54:27 AM »
The third major update of Windows 10 is there: Mixed Reality,  better Photo app, better Edge browser, improved security and PC gaming and more...

Today, we deliver the Windows 10 Fall Creators Update offering breakthroughs in creativity – from bringing mixed reality and 3D to the masses, to faster broadcasting for gaming, to turning photos and videos into real memories, and so much more. The Windows 10 Fall Creators Update can be experienced on a wide variety of Windows 10 PCs and on a range of Windows Mixed Reality headsets available for the first time today. We believe the PC is the ultimate canvas for creativity and can empower people to create like never before.

A defining feature of the new Volta GPU Architecture is its Tensor Cores, which give the Tesla V100 accelerator a peak throughput 12 times the 32-bit floating point throughput of the previous-generation Tesla P100.

Tensor Cores are already supported for Deep Learning training either in a main release or via pull requests in many Deep Learning frameworks (including Tensorflow, PyTorch, MXNet, and Caffe2). For more information about enabling Tensor Cores when using these frameworks, check out the Mixed-Precision Training Guide. For Deep Learning inference the recent TensorRT 3 release also supports Tensor Cores.

In this blog post we show you how you to use Tensor Cores in your own application using CUDA Libraries as well as how to program them directly in CUDA C++ device code.

esla V100’s Tensor Cores are programmable matrix-multiply-and-accumulate units that can deliver up to 125 Tensor TFLOPS for training and inference applications. The Tesla V100 GPU contains 640 Tensor Cores: 8 per SM. Tensor Cores and their associated data paths are custom-crafted to dramatically increase floating-point compute throughput at only modest area and power costs. Clock gating is used extensively to maximize power savings.

What are Tensor Cores?
Each Tensor Core provides a 4x4x4 matrix processing array which performs the operation D = A * B + C, where A, B, C and D are 4×4 matrices as Figure 1 shows. The matrix multiply inputs A and B are FP16 matrices, while the accumulation matrices C and D may be FP16 or FP32 matrices.

Each Tensor Core performs 64 floating point FMA mixed-precision operations per clock (FP16 input multiply with full-precision product and FP32 accumulate, as Figure 2 shows) and 8 Tensor Cores in an SM perform a total of 1024 floating point operations per clock. This is a dramatic 8X increase in throughput for deep learning applications per SM compared to Pascal GP100 using standard FP32 operations, resulting in a total 12X increase in throughput for the Volta V100 GPU compared to the Pascal P100 GPU.

Microsoft has released the Windows 10 SDK version 10.0.16299.15 for Fall Creators Update.

The Windows 10 SDK for Fall Creators Update (10.0.16299.15) provides the latest headers, libraries, metadata, and tools for building Windows 10 apps. When used in conjunction with the latest version of Visual Studio 2017, the Windows 10 SDK provides the optimum experience for building apps for Windows 10.

More information and download:

The complete SDK will took around 758MB on your disk after download.

Thank you Darin for your feedback. It's weird because I compiled and tested GeeXLab on Raspbian Stretch and I didn't see this issue. Anyway, I will update the OpenGL ES support for the next release. Thanks!

3D-Tech News Around The Web / Apple releases Darwin kernel (XNU) source code
« on: September 30, 2017, 06:24:41 PM »
XNU kernel is part of the Darwin operating system for use in OS X and iOS operating systems. XNU is an acronym for XNU is Not Unix. XNU is a hybrid kernel combining the Mach kernel developed at Carnegie Mellon University with components from FreeBSD and C++ API for writing drivers called IOKit. XNU runs on I386, X86_64 for both single processor and multi-processor configurations.


Creative Technology has released the first public version of its Aurora SDK (software dev kit) that allows developers to program lighting effects on Sound BlasterX RGB-enabled hardware like the Sound BlasterX AE-5 gaming sound card.
