3D-Tech News Around The Web / Intel HD Graphics Driver 20.19.15.4377
« Last post by Stefan on February 04, 2016, 04:48:05 PM »
Download from Microsoft
ATM only for SAMSUNG OEM with "Intel(R) HD Graphics 515"

Installation:

STEP 1)
Don't edit ki113672.inf with Notepad, it might save your result as ki113672.inf.TXT or asks you to open WordPad.
Instead use a professional (yet free) solution like Notepad++


STEP 2a)
disable driver signature - secure boot off
bcdedit -set loadoptions DISABLE_INTEGRITY_CHECKS
bcdedit -set testsigning ON

STEP 2b)
disable driver signature - secure boot on
bcdedit -set loadoptions DISABLE_INTEGRITY_CHECKS
enable testsigning via enhanced start options

STEP 3)
Follow this fool-proof "have disk" installation tutorial


No Changelog available, but:
GFXBench passes now all tests with driver 20.19.15.4377 + Windows 10 build 14257 on my rig.

Works fine on another laptop (with an Iris GPU), so must be some odd issue with the previous laptop I tried.

I updated my drivers, and also tried the 32-bit version - didn't solve the issue.

Never mind: I will try from a different laptop, which hopefully will work; I'll post again if it doesn't.

Thanks for your suggestions.

OK,
here is a generic flip code:

replace
iResolution.xy
with
vec2(iResolution.x, -iResolution.y)

Tested in toon video shader and ascii art

I'll upload the demos later with a non-commercial video

No plug-ins, no installing anything, just go to the site.

WebGL is the only way to run a 3D app on Windows, Mac, and Android, etc., with no source changes. The first and only time this has ever been possible – in the known universe! And as Apple fragments the native API landscape with Metal – this portability becomes even more valuable.

I was hoping you already have a function in LUA (equivalent to the magic button at Shadertoy.com)

Anyway i found the sweet spot in the pixelshader: simply replace iResolution.y with -iResolution.y or -1*iResolution.y
But it's only that easy in this particular shader because iResolution is split into x and y

To flip the texture in the shader, you have to play with the vec2 texture coordinates. Try something like that to flip the texture around the horizontal axis (by inversing the Y coordinate):

Code: [Select]
vec4 getColor( in vec2 xy )
{

...

if (int(iter) >= ITER_MAX)
{
  vec2 uv = zxy*0.25 + 0.5;
  uv.y *= -1.0;
  return texture2D(iChannel0, uv);
}

...

vec2 uv = vec2(picx, dist);
uv.y *= -1.0;
vec4 color = texture2D(iChannel0, uv);

...

}

GeeXLab 0.9.4.1 works fine on my Win10 64-bit + HD Graphics 530 GPU (with Intel drivers v4352). Your driver is v4326. I don't think that will make a difference but you can install latest Intel graphics drivers. Maybe you have an antivirus or firewall that is blocking GeeXLab. You can also try the 32-bit version of GeeXLab... Let me know.

There's no visible problem in the log file. Everything looks ok.
I have a test system with an Intel HD Graphics 530, let me do a quick test...
