SHADERed

SHADERed is a lightweight tool for writing and debugging shaders. It is easy to use, open source, cross-platform (runs on Windows, Linux & Web).

Shader debugger lets you easily find bugs in your shader code. It is simple to use - you just need to pause the preview and select the pixel that you want to debug. After starting the debugger, you will be able to:

step through your shader code line by line
run immediate expressions
add watches
place (conditional) breakpoints
see list of all variables and their values
hover over expressions and see their value

With SHADERed, you can debug vertex, geometry, tessellation control, pixel and compute shaders.

Thanks to SHADERed, you can now also debug shaders in Visual Studio Code with an extension. Read more about this in the blog post: https://shadered.org/blog?id=9.

Frame analyzer

Besides debugging your shader line-by-line, SHADERed also lets you find bugs and errors visually. After you run the frame analyzer, you will be able to:

detect undefined behavior
see variable's value throughout the whole frame
global breakpoints (color a pixel that meets a certain condition)
SPIR-V instruction heatmap

Compute & geometry shaders

You are not limited to vertex and pixel shaders. SHADERed also supports compute & geometry shaders. You can create advanced animations and effects with these two shader stages:

Plugin API

You can develop custom SHADERed plugins and upload them to SHADERed store so that they can be installed through SHADERed.

To see the plugin API's potential, check out these plugins:

GodotShaders - adds support for Godot's canvas shaders
ShadertoyImporter - import ShaderToy projects
GIFCapture - adds the ability to capture GIFs
Slang - adds support for Slang shader language
Rust - adds the ability to write shaders in Rust
C++ - adds the ability to write shaders in C++
Terminal - open terminal windows in SHADERed

See changes instantly

SHADERed can compile your shaders while you write the code. This way you can see your changes instantly. SHADERed also works nicely with external text editors (such as VS Code) - it will recompile the shaders that were modified by some external program.

Other features

SHADERed has lots of features that let you achieve effects like in no other shader editor. Features are also being added rapidly. Here are some of the feature:

render states (blending, stencil test, depth test, etc...)
import 3D models
built-in 3D geometry objects
import 2D texture, 3D textures, cubemaps
import audio files (build awesome music visualizers)
render textures (easily build G-Buffer)
buffers
instancing
profiling
multi-camera system
audio shaders (generate music on GPU)
custom variables & powerful variable system
zooming in on the preview window
exporting image sequence
code autocompletion designed for shader code
... and so much more!

Binaries

You can download precompiled binaries through the Releases page or via SHADERed's website.

Install using Scoop (Windows)

On Windows, you can use Scoop to install SHADERed:

scoop bucket add extras
scoop install shadered

Install using Flatpak (Linux)

SHADERed is available on Flathub. After setting up Flatpak, you can install it by entering the following commands in a terminal:

flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
flatpak install --user flathub org.shadered.SHADERed -y

Note that the Flatpak version runs in a sandbox and some features may not work correctly yet. Please report Flatpak-specific issues here.

Building

First clone the project & submodules:

git clone https://github.com/dfranx/SHADERed.git
cd SHADERed
git submodule update --init

Linux

Install all the libraries that are needed:

# Ubuntu
sudo apt install libsdl2-dev libglew-dev libglm-dev libgtk-3-dev
# Fedora
sudo dnf install glm-devel glew-devel SDL2-devel gtk3-devel

Build:

cmake .
make

If you would like to perform an out-of-source build, do the following:

mkdir build
cd build
cmake ..
make

Run:

./bin/SHADERed

macOS

NOTE: macOS is not officially supported by me + some features are not implemented for macOS

Install all the libraries that are needed:

brew install sdl2 glew glm

Build:

mkdir build
cd build
cmake ../
make -j8

Note: If you're building on a macOS version prior to 10.15 (Catalina) you may need to update Xcode and create a symlink for the SDK:
ln -s "$(xcrun --sdk macosx --show-sdk-path)" "$(xcrun --sdk macosx --show-sdk-platform-path)/Developer/SDKs/MacOSX10.15.sdk"

Run:

./bin/SHADERed

Windows

Install SDL2, GLEW & GLM through your favourite package manager (I recommend vcpkg)
Run cmake-gui and set CMAKE_TOOLCHAIN_FILE variable
Press Configure and then Generate if no errors occured
Open the .sln and build the project!
