3D-Tech News Around The Web / 3DMark Serra (new benchmark?)
« on: July 31, 2017, 10:41:09 AM »
Found this picture in one the Radeon RX Vega 64 articles:

We're excited to announce that in Windows 10 Fall Creators Update (FCU) due to ship in fall 2017, Windows Subsystem for Linux (WSL) will no longer be a beta feature and will become a fully supported Windows feature. Early adopters on the Windows Insider program will notice that WSL is no longer marked as a beta feature as of Insider build 16251.

This will be great news for those who've held-back from employing WSL as a mainline toolset: You'll now be able to leverage WSL as a day-to-day developer toolset, and become ever more productive when building, testing, deploying, and managing your apps and systems on Windows 10.


The content is running real time in 4K, the frame rate depends on the use of settings and with some optimization can run very fast on a single Titan or 1080TI (around 45 or perhaps I can hit 60). In SLI it is no problems to hit 60, so is playing it HD on regular cards. I am making use of Unreal engine and Nvidia's VXGI solution for real time lighting.

Youtube video:

The setup used to render this demo:
- Dual GTX 1080 Ti in SLI
- Intel Core i7 5960X
- Asus X99-E WS
- Corsair 64GB DDR4 2400MHz
- Acer 28" Predator XB281HK G-Sync 4K

GPU Caps Viewer is available.

More information and downloads links:

The Radeon GPU Profiler (RGP) is a ground-breaking low-level optimization tool from AMD.  It provides detailed timing information on Radeon Graphics using custom, built-in, hardware thread-tracing, allowing the developer deep inspection of GPU workloads.

This unique tool generates easy to understand visualizations of how your DirectX®12 and Vulkan® games interact with the GPU at the hardware level. Profiling a game is both a quick, and simple process using the Radeon Developer Panel and the public Crimson driver.

Supported GPUs:
- AMD Radeon R9 Fury and Nano series 
- AMD Radeon RX 400, RX 500 series

3D-Tech News Around The Web / Where do I start graphics programming?
« on: July 28, 2017, 08:21:44 AM »
Sometimes I get this question. And since it happens frequent enough, I decided I should write it publicly so that others can benefit, and also so I don’t have to repeat myself every time

In case you don’t know me, I’m self taught. I started doing graphics programming at age 14. My first experience was Visual C++ 6.0 and dived straight into C, C++ and assembly and came out just fine. The basics I learnt by reading a random PDF I found back then “Aprenda C++ como si estuviera en primero” (in Spanish) which was a very simple introduction to the language in 87 pages. What a variable is, what an enum is. How to do basic hello world.

Then I learnt a lot by trial and error. I started with several open source Glide Wrappers which were popular at the time. I used the debugger a lot to see line by line how the variables evolved. I would often remove some snippet of code to see what would happen if I took it out. I also played a lot with XviD’s source code.

Back then I had the DirectX SDK 7.0 samples and documentation to play with and I learnt a lot from it. In particular, Mathematics of Direct3D lighting fascinated me. I ended up writing my own TnL C library written in SSE assembly. It wasn’t very useful and I haven’t really updated it in more than a decade, but it helped a lot paving my foundations for when I came into contact with Vertex & Pixel Shaders. I was shocked that what took me an entire summer vacation and lots of assembly instructions (e.g. a matrix multiplication) could be done in one line of vertex shader code.



3D-Tech News Around The Web / Vulkan Synchronization Examples
« on: July 28, 2017, 08:19:24 AM »
Lot of synchronization examples are available here:

Synchronization in Vulkan can be confusing. It takes a lot of time to understand, and even then it's easy to trip up on small details. Most common use of Vulkan synchronization can be boiled down to a handful of use cases though, and this page lists a number of examples. May expand this in future to include other questions about synchronization.

GeeXLab - english forum / New way to live-code a GLSL shader
« on: June 18, 2017, 04:46:22 PM »
GeeXLab 0.16+ comes with a new and cross-platform way to live code GLSL shaders:

GeeXLab - english forum / GeeXLab 0.16.x released
« on: June 18, 2017, 04:41:43 PM »
A new version of GeeXLab is available for Windows 64-bit and Linux 64-bit.

Release highlights:

Version - 2017.06.17
+ added a new command line param to select the GPU for Vulkan (or Direct3D 12)
  demos: /gpu_index=x
! [WINDOWS] Vulkan plugin recompiled with latest Vulkan API headers (v1.0.51).
- [WINDOWS] removed from Tools menu entries related to network live updaters.
  Network live updaters tools are still available but in the nettools/ folder.
! [WINDOWS] GPU Shark utility moved to gpushark/ sub-folder. For some very
  obscure reasons, GPU Shark utility no longer works in the root
  folder of GeeXLab. But it works fine from the sub folder gpushark/.
* fixed a minor bug in the Lua kx framework for Vulkan.
+ added support of live-coding of GLSL shaders by editing the source
  code of a shader with any text editor.
+ added delay between two reloads of script files for live-coding of scripts.
! improved the performance of the Vulkan renderer.
! improved the support of AMD GPUs in the Vulkan renderer.
* fixed a bug in the Vulkan renderer in the creation of swapchain that led
  to a crash on NVIDIA GPUs.
+ added an automatic call to wait_for_gpu after all INIT scripts.
  Usefull with Vulkan or Direct3D 12 renderers.
+ added support of render targets in the Vulkan renderer.
! updated gh_texture.create_2d_from_rt() internals.
! [WINDOWS] updated the GPU monitoring plugin with NVIDIA GeForce GT 1030.

Boost.Compute is a GPU/parallel-computing library for C++ based on OpenCL.

The core library is a thin C++ wrapper over the OpenCL API and provides access to compute devices, contexts, command queues and memory buffers.

On top of the core library is a generic, STL-like interface providing common algorithms (e.g. transform(), accumulate(), sort()) along with common containers (e.g. vector<T>, flat_set<T>). It also features a number of extensions including parallel-computing algorithms (e.g. exclusive_scan(), scatter(), reduce()) and a number of fancy iterators (e.g. transform_iterator<>, permutation_iterator<>, zip_iterator<>).


The development branch brings the full support of OpenCL 2.1:

Code sample:
Code: [Select]
#include <vector>
#include <algorithm>
#include <boost/compute.hpp>

namespace compute = boost::compute;

int main()
    // get the default compute device
    compute::device gpu = compute::system::default_device();

    // create a compute context and command queue
    compute::context ctx(gpu);
    compute::command_queue queue(ctx, gpu);

    // generate random numbers on the host
    std::vector<float> host_vector(1000000);
    std::generate(host_vector.begin(), host_vector.end(), rand);

    // create vector on the device
    compute::vector<float> device_vector(1000000, ctx);

    // copy data to the device
        host_vector.begin(), host_vector.end(), device_vector.begin(), queue

    // sort data on the device
        device_vector.begin(), device_vector.end(), queue

    // copy data back to the host
        device_vector.begin(), device_vector.end(), host_vector.begin(), queue

    return 0;

3D-Tech News Around The Web / (Demoscene) How a 64k intro is made
« on: May 22, 2017, 10:01:58 AM »
How is made the Guberniya 64k intro, released at the Revision 2017:

The demoscene is about producing cool real time works (as in “runs on your computer”) called demos. Some demos are really small, say 64 kilobytes or less, and these are called intros. The name comes from “crack intros”. So an intro is just a demo that’s small.

I’ve noticed many people have interest in demoscene productions but have no idea how they are actually made. This is a braindump/post-mortem of our recent 64k intro Guberniya and I hope that it will be interesting to newcomers and seasoned veterans alike. This article touches basically all techniques used in the demo and should give you an idea what goes into making one. I refer to people with their nick names in this article because that’s what sceners do.
