How to Disable Avast CyberCapture (for Developers)

JeGX — Thu, 23 Jan 2020 14:01:08 +0000

I recently switched from Bitdefender to Avast. Avast seems to do a good job, is invisible (no ads every minute) and so far, does not have false positive detection on my binaries (GeeXLab, FurMark, GPU Caps Viewer, GPU Shark, and so on… — update: in fact, it has false positives!). Avast seems to be a solid antivirus except that window that appears each time … Continue reading How to Disable Avast CyberCapture (for Developers) »

Simple Display Emulator with an HDMI-VGA Adapter

JeGX — Fri, 09 Jun 2017 13:19:32 +0000

Several years ago, I wrote articles about a dummy VGA dongle based on a DVI-VGA adapter (see HERE and HERE). Let’s see if this old trick is still valid today with an HDMI-VGA adapter. The main goal of this dummy VGA/HDMI dongle is to fool Windows (or Linux or macOS) by simulating a ghost monitor that would be plugged on the HDMI port. To be … Continue reading Simple Display Emulator with an HDMI-VGA Adapter »

(WebGL) How to Enable Native OpenGL in your Browser (Windows)

JeGX — Tue, 11 Jun 2013 16:09:09 +0000

By default, both Firefox and Chrome use the ANGLE layer to render WebGL draw calls under Windows. ANGLE is an implementation of the OpenGL ES 2.0 specification that is hardware-accelerated via Direct3D 9. If, for some reasons (for some Shadertoy demos for example), you want to use real OpenGL draw calls, you can enable native OpenGL in Firefox and Chrome. In Firefox, just set the … Continue reading (WebGL) How to Enable Native OpenGL in your Browser (Windows) »

How to Quickly Test GLSL Shaders for ATI on a NVIDIA System?

JeGX — Sat, 02 Oct 2010 14:04:50 +0000

Why? GLSL is not the same on ATI and NVIDIA cards? Yes of course, GLSL code is the same on both cards but the compilation of GLSL is where both vendors diverge: ATI has a strict GLSL compiler while NVIDIA has a laxer one. Moreover, NVIDIA GLSL compiler is based on Cg one and you can use Cg / HLSL types in GLSL like float3 … Continue reading How to Quickly Test GLSL Shaders for ATI on a NVIDIA System? »

How To Get the List of the OpenGL Extensions With a Core Profile

JeGX — Thu, 22 Jul 2010 10:11:00 +0000

In this news we learnt that GLEW fails to initialize when an OpenGL 3 or 4 core profile is used because GLEW uses the deprecated glGetString(GL_EXTENSIONS) to read the available extensions. With OpenGL 3 and 4, there is a new way to fetch the supported extensions First you have to get the number of extensions with: GLint n=0; glGetIntegerv(GL_NUM_EXTENSIONS, &n); Now you can list all … Continue reading How To Get the List of the OpenGL Extensions With a Core Profile »
