# gl-compute
Simple tests of OpenGL 4.3 compute shaders.
Note that you need a recent OS to run this. Ubuntu 16.04 or newer should do.
### Compiling
We need CMake, Qt4 and GLM:
```
$ sudo apt install cmake libqt4-dev libglm-dev
```
Configure, compile and run:
```
$ mkdir build; cd build
$ cmake ..
$ make
$ ./mandelbrot
$ ./isosurface
```
### Troubleshooting
Check what OpenGL versions your Linux system supports:
```
$ glxinfo | grep version
server glx version string: 1.4
client glx version string: 1.4
GLX version: 1.4
Max core profile version: 4.5
Max compat profile version: 3.0
Max GLES1 profile version: 1.1
Max GLES[23] profile version: 3.2
OpenGL core profile version string: 4.5 (Core Profile) Mesa 17.2.8
OpenGL core profile shading language version string: 4.50
OpenGL version string: 3.0 Mesa 17.2.8
OpenGL shading language version string: 1.30
OpenGL ES profile version string: OpenGL ES 3.2 Mesa 17.2.8
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.20
```
On some systems, OpenGL 4.3 may not be enabled by default. Try running
with the following environment variable:
```
$ MESA_GL_VERSION_OVERRIDE=4.3 ./mandelbrot
```
