2 – Release Notes

GeeXLab 0.60.0 is available for Windows 32/64-bit, Linux 64-bit (GLIBC 2.31) and ARM64 (GLIBC 2.36).

This new version of GeeXLab brings many small changes, bug fixes and improvements.

Updated libraries

The following libraries have been updated to their latest versions:

Core libraries:
– Lua engine: version 5.4.7 (all platforms)
– Dear ImGui: version 1.91.1 (all platforms)
– SQLite engine: version 3.46.1 (all platforms)
– curl: version 8.10.0 (windows)
– LuaSocket: version 3.1.0 (all platforms)

Plugin libraries:
– FFmpeg: version 7.0.2 (windows – other platforms: 7.0)
– ASSIMP: version 5.4.2 (all platforms)
– PhysX 5: version 5.4.0 (windows)
– Python 3: version 3.12.6 (windows)

GeeXLab 0.60.0 is behind all the following applications: FurMark 2.4, GPU Shark 2.4, ASUS FurMark 2 ROG Edition 2.4, YAFFplayer 0.10.0, h4shg3n 0.5.5, MSI Kombustor 4.1.30 and MadView3D 0.5.0! That’s why this release took me a bit time to finalize.

arm64 / aarch64 and Raspberry Pi platforms

A word about arm64 / aarch64 platform. Now GeeXLab is available in two flavors for arm64: one pure arm64 version and one arm64 version for Raspberry Pi. Both versions have been compiled on Raspberry Pi OS Bookworm on a RPi 5 hardware. The pure arm64 version should work on any Linux for arm64 with GLIBC 2.36 or higher. I don’t have a non-RPi arm64 platform, so if you, dear reader, have such a platform, please try to launch GeeXLab and let me know if it works. The second version is still for arm64 but specifically for Raspberry Pi hardware / OS: this version has dependencies with the RGBA Led Matrix support and GPIO support using WiringPi.

A second word about arm64 versions. GLIBC 2.36 is now required because GeeXLab is now compiled on the Raspberry Pi 5 board with Raspberry Pi OS Bookworm (Debian 12). It’s now a pleasure to work with the RPi 5, this board is fast and everything run smoothly (except Xwayland that still does not work). The latest iteration of Raspberry Pi OS Bookworm (July 4th 2024) seems to work on all Raspberry Pi hardware (RPi3, RPi4 and RPi5) that’s why Debian 12 Bookworm is now my new OS for RPi development.

NVIDIA Vulkan driver on Windows

Let’s quickly talk about the gh_renderer.bind_render_window() added to GeeXLab 0.60.1. This function is called in the startup demo of GeeXLab (in the startup-demo/ folder in init.lua). The call to bind_render_window() deserves an explanation.

Without this call, the startup demo crashes if there are two NVIDIA graphics cards in the system. In my development machine, I have a GeForce RTX 2070 + GeForce GT 1030 drove by R561.09. If I remove the GT 1030, the demo works fine. With both cards, the demo crashes. This is an OpenGL demo that in middle of the init script, initializes Vulkan and reads Vulkan information (see InitVkInfo()). Any OpenGL call after InitVkInfo() leads to a crash (OpenGL function pointers seem correct but crash when we called them). After few hours of debugging, I had the feeling that the crash happened as if the OpenGL context was lost or not properly restored after Vulkan calls. That’s why I tested with bind_render_window() and… YES, that fixed the crash! The bind_render_window() function is a wrapper around wglMakeCurrent.

However, it’s not a victory. The crash is still there in 32-bit. With bind_render_window() the crash disappears in 64-bit but not in 32-bit.

Duplicated Vulkan devices

The other thing is that with 2 graphics cards, the NVIDIA Vulkan driver duplicates all Vulkan physical devices. Instead of detecting
two physical devices (the RTX 2070 and the GT 1030), the NVIDIA Vulkan driver returns:
– GPU 0: NVIDIA GeForce RTX 2070
– GPU 1: NVIDIA GeForce RTX 2070
– GPU 2: NVIDIA GeForce GT 1030
– GPU 3: NVIDIA GeForce GT 1030

There is probably a bug in the NV VK driver. I tried to uninstall it (I used the latest DDU 18.0.8 for that), reinstalled it, but no change, any Vulkan utility (GPU Shark 2, GPU Caps Viewer, Vulkan Capability Viewer, vkinfo, GLview) still displayed 4 devices…

Modern graphics programming is blood, sweat and pain!

2 – Release Notes

GeeXLab 0.57.0 is available for Windows 32/64-bit and Linux 64-bit (built with GLIBC 2.31).

Bug fixes

This new update of GeeXLab is more a maintenance release than a version with new features. Several bugs have been fixed (in GPU monitoring for Intel Arc GPUs, in the Vulkan plugin, in the PhysX 5 plugin).

Dear ImGui

Dear ImGui has been updated with latest version 1.90.1 and list clipping functions have been updated (list clipping allows the handling of lists with large number of items, like 10’000 or 100’000 items — a code sample is available in the OpenGL 2.1 demopack: geexlab-demopack-gl21/d29-imgui/imgui-list-clipping/).

Python 3

The Python 3.12 plugin has been refreshed with latest Python 3.12.2.

And for those who don’t want to download and unzip a 200MB (or more) zip file just to run a shader effect demo, I added a nano version of GeeXLab (10MB). The nano version comes with 3 plugins only: Vulkan, FMOD and the GPU monitoring.

3 – Changelog

This changelog is intended for all versions of GeeXLab.

2 – Release Notes

GeeXLab 0.55.0 is available for Windows 32/64-bit. I will update Linux64, macOS and Raspberry Pi later (for the RPi, I’m waiting the for RPi 5…). GeeXLab 0.55 engine is behind latest versions of GPU Shark 2, FurMark 2, MSI Kombustor and FurMark ROG and YAFFplayer.

Here are the main changes:

FFmpeg plugin

The FFmpeg plugin has been updated with latest version 6.1.0 code-named Heaviside (Oliver Heaviside was a famous mathematician and physicist with important contributions in electromagnetism and electricity). I fixed many bugs in the FFmpeg plugin and updated the CUDA support (now its works!). FFmpeg 6.1 comes with the Vulkan support for some decoders like the H264 but as always with Vulkan, things are not easy to do. So no Vulkan support in the FFmpeg plugin. Maybe later.

Python 3 plugin

A new Python 3 plugin is available for Python 3.12. Now, GeeXLab supports all versions of Python 3 from Python 3.7 to the latest Python 3.12.

2 – Release Notes
GeeXLab 0.54.0 is available for Windows 32/64-bit and Linux 64-bit. GeeXLab 0.54 engine powers all latest versions of GPU Shark 2, FurMark 2, MSI Kombustor and FurMark ROG. Other tools like YAFFplayer or MadView3D will be update shortly. The public release of FurMark 2 is imminent, after what I’ll take time to update GeeXLab for Raspberry Pi (the RPi 5 is around the corner) and macOS versions.
Here are the main changes:
PhysX 5 plugin
The PhysX 5 plugin has been updated with latest PhysX 5.3.0 and is now available on Windows and Linux platforms.
ASSIMP plugin
The ASSIMP plugin has been updated with latest ASSIMP 5.3.1. This last version ASSIMP brings only minor changes (bugfixes) but updating to the latest version doesn’t hurt.
Vulkan plugin
I updated the Vulkan plugin and improved a bit the acquire / present part with better synchronization. I added the fullscreen exclusive mode support but I didn’t manage to get it work. According to the specs and the Vulkan SDK, the VK_KHR_get_surface_capabilities2 extension is required by the VK_EXT_full_screen_exclusive extension. But weirdly, VK_KHR_get_surface_capabilities2 is not exposed by latest NVIDIA, AMD or Intel drivers. Maybe I missed something. It doesn’t matter, the FSE support is there and I will update it as soon as possible. 
GPU monitoring plugin
I added the support of latest Radeon RX 7800 XT / RX 7700 XT and I added a new function (gh_gml.get_gpu_commercial_name()) that retrieves the commercial name of a graphics card. For example get_gpu_commercial_name return MSI RTX 2070 Ventus 8G for my RTX 2070. I tried to support most of the GeForce RTX 30 / RTX 40, Radeon RX 6000 / RX 7000 and Intel Arc graphics cards.
Internal libraries updates
The following libraries have been updated to their latest versions:

– Python 3.11.6

– Dear ImGui 1.89.9

– SQLite 3.43.1

– ImPlot 0.16

– imspinner

– imgui-filebrowser

– Spout 2.007.012
Last thing, now, when a new version is available you will see a small dialog box showing the new version as well as the download button:

Shadertoy Demopack v23.3.28

JeGX — Tue, 28 Mar 2023 08:32:12 +0000

Downloads

A new version of the Shadertoy demopack is available to enjoy Shadertoy demos on your PC. The Shadertoy demopack is a selection of the coolest demos available on shadertoy website.

New shadertoy demos are in the following folders:
– gl-shadertoy-singlepass/
– gl-shadertoy-multipass/

Unzip the pack where you want, and drag and drop any demo (main.xml or demo.xml) into GeeXLab.

If you want to benchmark and log scores, you can do it via command line:

GeeXLab /width=1920 /height=1080 /fullscreen /demofile="absolute_path_to_the_demo.xml" /demofile_abs_path=1 /no_menubar /benchmark_duration_ms=10000 /benchmark_log_score

Many demos, if not all, are shipped with live-coding ready pixel shader. That means you can edit the shader file (shader_img.glsl in single pass demos) in your favorite text editor and any change is instantly visible.

New demos:

Here is a small demo that shows how to use two new widgets added in the gh_imgui library (Lua and Python).

This demo requires GeeXLab 0.50+ and is available in the OpenGL 2.1 demopack in the geexlab-demopack-gl21/d29-imgui/imgui-knob-toggle/ folder.

Here is a code snippet in Lua that shows how to use the toggle widget:

ImGuiToggleFlags_None                   = 0
ImGuiToggleFlags_Animated               = 1  
ImGuiToggleFlags_BorderedFrame          = 8  
ImGuiToggleFlags_BorderedKnob           = 16 
ImGuiToggleFlags_ShadowedFrame          = 32 
ImGuiToggleFlags_ShadowedKnob           = 64 
ImGuiToggleFlags_A11y                   = 256

size_x = 40
size_y = 20
toggle_flags = ImGuiToggleFlags_Animated
animation_duration = 0.1
frame_rounding = 1.0 
knob_rounding = 1.0 
label = "Horizontal drag"
DragHorizontal = gh_imgui.toggle(label, DragHorizontal, 
                                 size_x, size_y, toggle_flags, animation_duration, 
                                 frame_rounding, knob_rounding)

The original knob library in C/C++ for Dear ImGui is available HERE.

And a code snippet in Lua showing the use of the knob widget:

ImGuiKnobVariant_Tick = 1
ImGuiKnobVariant_Dot = 2
ImGuiKnobVariant_Wiper = 4
ImGuiKnobVariant_WiperOnly = 8
ImGuiKnobVariant_WiperDot = 16
ImGuiKnobVariant_Stepped = 32
ImGuiKnobVariant_Space = 64 

ImGuiKnobFlags_NoTitle = 1
ImGuiKnobFlags_NoInput = 2
ImGuiKnobFlags_ValueTooltip = 4
ImGuiKnobFlags_DragHorizontal = 8
-- this is special flag fopr GeeXLab only.
ImGuiKnobFlags_ReadOnlyInput = 16 
-- this is special flag fopr GeeXLab only.
ImGuiKnobFlags_DisableMouse = 32 

knob_flags = 0 
v_min = 0.0
v_max = 100.0
speed = 0.5
format = "%.1f"
size = 100
steps = 0
ret = 0
value = 0

label = "Tick"
knob_type = ImGuiKnobVariant_Tick
value, ret = gh_imgui.knob(label, knob_value01, v_min, v_max, speed, format, knob_type, size, knob_flags, steps)
if (ret == 1) then
  -- value has changed
  knob_value01 = value
end

Today, a new tweet shader made by yonatan using twigl.app (online editor for coding one tweet pixel shaders). This shader is very cool and I ported it to GeeXLab.

for(float i,g,e,R,S;i++<1e2;o.rgb+=hsv(.4-.02/R,(e=max(e*R*1e4,.7)),.03/exp(e))){S=1.;vec3 p=vec3((FC.xy/r-.5)*g,g-.3)-i/2e5;p.yz*=rotate2D(.3);for(p=vec3(log(R=length(p))-t,e=asin(-p.z/R)-.1/R,atan(p.x,p.y)*3.);S<1e2;S+=S)e+=pow(abs(dot(sin(p.yxz*S),cos(p*S))),.2)/S;g+=e*R*.1;} pic.twitter.com/rKA0dGDCdr

Original pixel shader:

for(float i,g,e,R,S;i++<1e2;o.rgb+=hsv(.4-.02/R,(e=max(e*R*1e4,.7)),.03/exp(e))){S=1.;
vec3 p=vec3((FC.xy/r-.5)*g,g-.3)-i/2e5;p.yz*=rotate2D(.3);
for(p=vec3(log(R=length(p))-t,e=asin(-p.z/R)-.1/R,atan(p.x,p.y)*3.);
S<1e2;S+=S)e+=pow(abs(dot(sin(p.yxz*S),cos(p*S))),.2)/S;g+=e*R*.1;}

Here is the same pixel shader in the GeeXLab demo:

#version 150
uniform float time;
uniform float frame;
uniform vec2 resolution;
in vec4 v_texcoord;
out vec4 FragColor;

#define PI 3.14159265
#define FC gl_FragCoord

vec3 hsv(float h, float s, float v)
{
  vec4 t = vec4(1.0, 2.0 / 3.0, 1.0 / 3.0, 3.0);
  vec3 p = abs(fract(vec3(h) + t.xyz) * 6.0 - vec3(t.w));
  return v * mix(vec3(t.x), clamp(p - vec3(t.x), 0.0, 1.0), s);
}

mat2 rotate2D(float r)
{
  return mat2(cos(r), sin(r), -sin(r), cos(r));
}

void main()
{
  vec2 r = resolution;
  float t = time;
  float f = frame;
  vec4 o = vec4(0.0);
  vec3 p = vec3(0.0);
  float i=0,g=0,e=0,R=0,S=0;
  for(; i++<1e2; o.rgb += hsv(.4-.02/R,(e=max(e*R*1e4,.7)),.03/exp(e)))
  {
    S=1.;
    vec3 p=vec3((FC.xy/r-.5)*g,g-.3)-i/2e5;
    p.yz*=rotate2D(.3);
    for(p=vec3(log(R=length(p))-t,e=asin(-p.z/R)-.1/R,atan(p.x,p.y)*3.);S<1e2;S+=S)
      e+=pow(abs(dot(sin(p.yxz*S),cos(p*S))),.2)/S;
    
    g+=e*R*.1;
  }

  FragColor = o;
}

The GeeXLab demo (just drop geexlab-demopack-gl32/d30-twigl/twigl06.xml in GeeXLab):

The shader is ready for live coding. Just edit the shader (d30-twigl/shaders/ps06.glsl) in your favorite text editor and save it to see the result in real time.

On a GeForce RTX 2070, this demo runs at 190 FPS (resolution: 800x800).

GeeXLab 0.49 Released for Windows and Linux (Updated: v0.49.3)

JeGX — Wed, 30 Nov 2022 12:15:27 +0000

Downloads

GeeXLab 0.49.3 (linux64) (113MB)

GeeXLab 0.49.2 (macOS M1 / arm64) (16MB)

1 – Release Notes

This new version of GeeXLab is available for Windows 64-bit, Windows 32-bit and Linux 64-bit (GLIBC 2.31). This version of GeeXLab is used as the foundation of several new GPU tools: GPU Shark 2, FurMark 2 and GPU Magick. All these tools will be released very shortly.

Here are the main changes in GeeXLab 0.49:

GPU Monitoring plugin

The GPU monitoring plugin comes with the support of recent NVIDIA GPUs: GeForce RTX 4090 and GeForce RTX 4080, GeForce RTX 3060 Ti GDDR6X and RTX 3060 GDDR6X. The fan speed reading has been improved for GeForce GPUs: all fans can bee now monitored (new functions in gh_gml library: get_num_fans() and get_fan_speed_v2()).

The major new feature in the GPU monitoring plugin is the support of Intel Arc GPUs: Arc A380, Arc A750 and Arc A770. All important hardware sensors can be monitored: GPU temperature, GPU usage, fan speed, chip power consumption, GPU and memory clock speed. The monitoring of Arc GPUs is only available on Windows 64-bit.

GPU Shark 2 (based on GeeXLab and soon available) has the monitoring of Intel Arc GPUs:

Python 3.11 Support

The latest version of Python 3 is now supported. GeeXLab can now execute scripts for Python 3.7, Python 3.8, Python 3.9, Python 3.10 and Python 3.11. The Python demopack contains a set of demos to check the support of all versions of Python (folder: geexlab-demopack-python3/general/01-system-info-v2/).

On the Windows version, Python 3.8 is the default Python version when you specify only PYTHON_3 in the XML script node. On Linux, the default Python version is now Python 3.10. GeeXLab allows you to specify the Python version in your scripts (PYTHON_3_7, PYTHON_3_10, etc.) as well as Python’s home directory.

Lua Engine

I slightly modified the Lua engine in order to display longer file names in error messages. By default, the length of file names is 60 bytes. The new length is now 512 bytes.

Vulkan plugin

The instance creation is now done with Vulkan 1.1 (VK_API_VERSION_1_1). For ray tracing, the version 1.2 is recommended. You can specify the Vulkan version (vulkan1.2 or vulkan1.3, default is vulkan1.1) in the XML window node:

The support of multi-sampling anti-aliasing has been added to the Vulkan plugin. You can enable this support in the window node:

In OpenGL, the MSAA support can be enabled or disabled at any moment in the frame script. This feature is not possible in Vulkan.

ImGui

GeeXLab 0.49 comes with the latest Dear ImGui 1.89 final. The ImPlot support has been updated with version 0.14 and some functions to draw plots have been updated with new parameters. A demo is available in the OpenGL 2.1 demopack: geexlab-demopack-gl21/d29-imgui/imgui-implot/.

I took the time to add a cool lib in GeeXLab to draw some spinners with ImGui. A demo is available in OpenGL 2.1 demopack: geexlab-demopack-gl21/d29-imgui/imgui-imspinner/.

Libraries Update

The following libraries have been updated to their latest versions:
– Dear ImGui: 1.89.1
– ImPlot: 0.14
– SQlite: 3.40.0
– SDL2 (FFmpeg plugin): 2.0.26
– curl: 7.86.0
