Today, we are releasing Build 14251 Windows Insiders in the Fast ring.
 
Sharp-eyed Insiders likely noted the big jump in build numbers from our last preview build (11102). Historically, the codebase for mobile had a different OS version than the codebase for PC because they were developed by different teams on different schedules. With Windows 10, we became one Windows team and brought these two codebases together. We started by changing the version string displayed in the UI to be consistent, which is why you saw similarly labeled builds over the past year for both Mobile and PC, but the underlying binary version numbers were still different. As part of our work getting the common codebase ready for the next release, we decided to complete that work and sync the build numbers between mobile and PC. Because the mobile codebase used higher build numbers than PC, we needed to jump ahead a bunch of build numbers to ensure updates to future builds will continue to work. So that’s why build numbers went from 11105, 11106, and 11107 to 14251.

This build doesn’t have notable new features in it but I encourage you to check out the new Cortana improvements we released to Insiders earlier this week. The January update to the Xbox Beta app for Windows 10 is also now available with some really nice improvements for Insiders to try out and give us feedback.

This build does contain some really good bug fixes that Insiders will appreciate:
 
  • We fixed the issue where some PC games would crash switching from windowed mode to full screen, upon game resolution change, or upon launch due to a bug in Windows graphics stack. So play your games! If you run into any issues – please let us know by reporting in the Feedback app and include the game title.
  • We fixed the issue where applications such as Narrator, Magnifier, and third-party assistive technologies may experience intermittent issues or crashes.
  • We fixed an issue where File Explorer would crash frequently when DPI settings were at 175%.
I also want to reiterate once again that with the change to release builds faster to Windows Insiders in the Fast ring, bugs like the ones we had in the last build (or the File Explorer copy UX from the prior build) are going to pop up. Sometimes it might be several builds before we get these bugs fixed. And there might be times where a build we release contains bugs we haven’t found in internal testing as well.

We’re at the beginning of a new development cycle for our next feature update to Windows 10, and that means teams will be checking in lots of new code as they integrate their feature payloads. Being an Insider means you’re getting the latest code changes, and working with new builds that are relatively new even for Microsoft employees. If this worries you, you can switch to the Slow ring and stick with less frequent but more stable builds.

English forum / How to use keyboard in ported Shadertoy demos
« on: January 27, 2016, 05:08:34 PM »
Here is a nice keyboard controlled demo: Key Quest

I tried to port it to GeeXLab - download here

Keyboard action in the info quad works fine, but i have no idea how to send virtual key codes through the "iChannel" to the pixel shader.

Thats' what i tried:

Code: [Select]
...
  if (gh_input.keyboard_is_key_down(KC_B) == 1) then
    _keyboard_last_time = elapsed_time
    key_str = "B"
    virtual_key = 66
  end
...

-- this doesn't work...
gh_gpu_program.uniform1i(shadertoy_prog, "iChannel3", virtual_key)

-- this works
gfx.write_text(10, 160, 1, 1, 0, 1, "Press buttons ABCDEFGHK")
gfx.write_text(10, 180, 1, 0, 0, 1, "" .. key_str)

Here is a pack with mouse-click controlled shaders

I remember to have stumbled over Shadertoy demos with keyboard control, but i passed on them because the keyboard is stuffed in an iChannel

I take another look if i find these demos again...

OK,
got it working now

Code: [Select]
local mx, my = gh_input.mouse_getpos()
local mz = gh_input.mouse_get_button_state(1)
local mw = mz

gh_gpu_program.uniform4f(shadertoy_prog, "iMouse", mx, -(my - winH), mz, mw)


I will add both mouse-click and mouse-over versions to next demo pack.

Here is another demo: 2D Radial Repeat : Hex RadClick
Besides mouse i patched other issues.

section id
shifted to bottom left of the screen, away from GeeXLab's overlay

uv.x += iDate.w ; // rotate each radius offset with constant speed
doesn't work, replaced with
uv.x += iGlobalTime ;

mouse click
if(iMouse.z>0.) pos = iMouse.xy;
replaced with mouse over
if(iMouse.x>20.) pos = iMouse.xy;

From my understanding each website needs to be recoded for that.

Otherwise you can  "Enable multi-process" in new FF versions.

I found a demo LED scoreboard, that is controlled by mouse-click.
How do i do that in GeeXLab, sth. with gh_input.mouse_get_button_state() ?
EDIT: solution below

As a work-around i replaced mouse-click with mouse-over in the pixel shader

    vec3 col = iMouse.w > 0.5 ? flag( DE ) : flag( RU );
    if ( p.x > 0.5 + halfStripe ){ col = iMouse.w > 0.5 ? flag( RU ) : flag( DE ); }

   
replaced with

    vec3 col = iMouse.x > 0.5*iResolution.x ? flag( DE ) : flag( RU );
    if ( p.x > 0.5 + halfStripe ){ col = iMouse.x > 0.5*iResolution.x ? flag( RU ) : flag( DE ); }

3D-Tech News Around The Web / Firefox - WebGL Off the Main Thread

WebGL Off the Main Thread

We’re happy to announce WebGL in Web Workers in Firefox 44+! Using the new OffscreenCanvas API you can now create a WebGL context off of the main thread.

To follow along, you’ll need a copy of Firefox 44 or newer (currently Firefox Developer Edition or Firefox Nightly). You’ll have to enable this API by navigating to about:config in Firefox, searching for gfx.offscreencanvas.enabled, and setting it to true.  You can grab the code examples from GitHub or preview it here in Firefox 44+ with gfx.offscreencanvas.enabled set to true.  This functionality is not yet available on Windows pending ANGLE support.  AlteredQualia points out things are running great on Windows/FF Nightly 46.

Sample Application for Direct3D 12 Flip Model Swap Chains

Using swap chains in D3D12 has additional complexity compared to D3D11. Only flip model [1] swap chains may be used with D3D12. There are many parameters that must be selected, such as: the number of buffers, number of in-flight frames, the present SyncInterval, and whether or not WaitableObject is used. We developed this application internally to help understand the interaction between the different parameters, and to aid in the discovery of the most useful parameter combinations. The application consists of an interactive visualization of the rendered frames as they progress from CPU to GPU to display and through the present queue. All of the parameters can be modified in real time. The effects on framerate and latency can be observed via the on-screen statistics display.

Note for NVIDIA Optimus users:
NVCPLUI.EXE must run in admin mode to find Windows store apps.

3D-Tech News Around The Web / NVIDIA - Engaging the Voyage to Vulkan
« on: January 16, 2016, 12:22:29 AM »
Vulkan is currently in its final stage of development and we want to share with you what makes it a great graphics API and what some of the differences to OpenGL are. NVIDIA believes strongly that Vulkan supplements OpenGL, and that both APIs have their own strengths.
Vulkan’s strengths lie in the explicit control and multi-threading capabilities that by design allow us to push more commands to the GPU in less CPU time and have finer-grained cost control.

Welcome to 2016 and a new year full of new builds for Windows Insiders. Today we have a new PC build we’re releasing to Insiders in the Fast ring: Build 11099.
 
As with the previous build, this build does not include big noticeable changes or new features yet. Our focus through the holidays was on structural improvements to OneCore, which is the shared core of Windows across devices. The code refactoring and other engineering work we’ve been doing to optimize OneCore is nearing the point where we will be ready for teams to begin checking in new features and improvements. It will still be a few builds before any really noticeable changes show up, depending on when teams begin lighting up new features in their areas. We’re excited for Insiders to use this build to validate the work we’ve been doing to OneCore, so give this build a try and let us know of any issues you run into via the Windows Feedback app.
 
As I explained in the prior post, we are making some changes to how we release builds to the Fast ring starting in 2016. The criteria we use to release builds to Windows Insiders in the Fast ring will be much closer to our criteria for flighting to our internal rings. This will allow more builds to reach Windows Insider. This also means that the builds we release to the Fast ring may include more bugs and other issues that could be slightly more painful for some people to live with. If you’d rather stick with less frequent but more stable builds, you can switch to the Slow ring by going to Settings > Update & Security > Windows Update > Advanced options and under “Get Insider Preview builds” moving the slider to the Slow ring.
 
As a reminder, we will be publishing known issues for builds we release in the Insider Hub rather than in our blog posts here. You can find the known issues for this build here.
 
I do want to note something that we fixed in this build which was a known issue in the last build: the progress dialog when copying or deleting files via File Explorer now shows up as expected.
