A simple application to run GLSL shader programs as the root window on systems using X.

The window manager used in these screenshots is DWM and I am using Luke Smith's dwmblocks build to set the status with some custom scripts. Using the gradient.frag shader program

1. Clone the repo git clone https://github.com/lord-123/xshader.git
2. cd into the directory.
3. Configure the program by modifying config.h if you so wish.
4. Run sudo make clean install.
5. Add xshader & to your .xinitrc.
6. Logout and log back in to update the background.

• SHADER_PATH is the location of the fragment shader program (note: by default the example /shaders directory is copied to ~/.local/bin/shaders). It must be an absolute directory (no ~/). This may be changed in the future.
• DELAY is how often the program will be delayed between redrawing the screen. Having this low can be a serious power draw on laptops so watch out.
• The number of shader uniforms used MUST be set correctly in UNIFORM_COUNT. This may not be necessary in a future update.
• The custom uniforms are defined by their name and a custom updater function.

• Custom handwritten shaders
• Completely customizable
• Written in pure C for maximum efficiency and minimal power consumption
• Supports custom uniforms which update each frame (animated wallpapers)

• One time shaders at the start of the program
• Seperate shader update rates

I would be very grateful for anybody wanting to contribute anything. Issues and pull requests would be excellent, however, if you would like a substantial feature, I might suggest creating a different fork as I am trying to keep this as minimal as possible. Custom shaders from people would be a great addition to this project.
