partikel_accelleration_on_gpu's Introduction

Particle-Simulation using the GPU via the OpenGL Compute-Shader

This particle simulation is more like a proof of concept for myself or others, to show and understand how compute shaders in OpenGL work. Using the knowledge I gathered from this project, more complex, fascinating and fast projects are possible, which use the power of the graphics hardware for computations.

The final result looks like that:

Animation

Each particle has a life span in which it fades from red (new born) to blue (about dying). When a particle dies, it respawnes in its negated (x,y,z) position.

The movement itself is computed using an Euler integration method for each particle.

There are several global randomly moving attraction points. Particles are attracted and accelerated by these points.

Example screenshots:

Install && Run

I tested an ran this simulation on a debian-based Linux OS (Ubuntu, Mint, ...). It should run on other machines as well but is not tested.

System Requirements

The following system attributes are required for running this simulation:

A graphics card supporting OpenGL version 4.3 (For the compute-shader!).
Unix-Libraries: xorg-dev and mesa-common-dev

Both GLEW (The OpenGL Extension Wrangler Library) and GLFW (Window-Manager) are now included locally, so no system wide installation is necessary!

For a system wide installation, further information is available under the following links:

GLFW: http://www.glfw.org/.
GLEW (with install instructions): http://glew.sourceforge.net/build.html.

Running

Compiling and running should work under windows. OSX is not supported as the available OpenGL version does not reach 4.3. In the root directory, execute:

cmake .
make
cd bin/
./particleSim

While the simulation runs, you can move around (always looking to the center!) with your mouse (left-klick and move) and zoom in/out with your mouse (right click and move up/down).

More Screenshots

So, here are some more screenshots, because screenshots are awesome :)

You can find some more screenshots in the screenshot-folder: More Screenshots :).

G_Attractor_Mass initialization

It seems G_Attractor_Mass initialization is missing... or am I wrong?

Because it should be null when you try to assign it to the vec.w

vec.w = G_Attractor_Mass[i];

running errors: GLSL 4.30 is not supported.

When running the codes, it showed the errors

Then, I checked my computer with glxinfo and it shows

OpenGL vendor string: Intel Open Source Technology Center

OpenGL core profile version string: 4.6 (Core Profile) Mesa 20.2.6

It seems that my computer supports 4.6 Core profile. How do I know if my computer supports GLSL 4.30 or not? Thank you!

Compile Error In Shader

I am trying to run The Legend Of Zelda: Breath of the Wild on my PC with cemu but it crashes when it loads. My log looks like this:

[20:27:21] Compile error in shader. Log:
[20:27:21] 0:1(10): error: GLSL 4.30 is not supported. Supported versions are: 1.10, 1.20, 1.30, 1.40, 1.50, 3.30, 1.00 ES, and 3.00 ES

any Help?

Flickering

Hi, I compiled and ran your program, it works but I get a lot of flickering (blue, red, blue, red). I would like to know if you have the same problem.

I am using Ubuntu.

Thanks in advance.

Wont run Mac os
