SHADERed

SHADERed is a lightweight tool for creating and testing HLSL and GLSL shaders. It is easy to use, open source and frequently updated with new features. It has many features that the competition is lacking.

Features

See changes instantly

You can press F5 (or whatever shortcut you have set in the options) to see you changes:

Don't want to press F5 constantly? Using an external editor and not the built-in one? Turn on the "Recompile shader on file change" flag in the options and once you make changes to the file, SHADERed will instantly detect that and recompile your shaders:

Want to see how a certain object affects your scene? Grab the object and scale, rotate and move it around the scene:

Geometry shaders

You are not limited to vertex and pixel shaders. SHADERed also has support for geometry shaders. Just enable GS in your shader pass and set the path to your shader. Create advanced animations and effects using geometry shaders.

Render states

You can modify rasterizer, blend and depth-stencil state. Using these states you can: turn on wireframe mode, disable depth test, use stencil buffer, disable culling, custom blending, etc... All those things help you achieve even more advanced effects.

Heres an example of rasterizer state properties:

Audio files

Load a song and create amazing music visualizers!

Loading 3D models

You can easily add your custom 3D models to the scene. You can also add built-in geometry objects such as cubes, spheres, planes, full screen quads, etc...

Textures

Load textures from files and bind them to your shader. SHADERed also supports cubemaps.

Render textures

You can render your results to a window or a custom render texture. You can bind multiple render textures to one shader pass. It helps you create things such as G-Buffer more easily and in only one shader pass.

Shader input variables

You can create your own variables and edit their values. Those variables will be sent to a shader using a constant buffer. There are also a lot of built-in 'system' shader variables (elapsed time, window size, various view matrices, etc...).

You can also pin those variables. All pinned variables (from different shader passes) will be visible on a single window. You can edit them there easily and see your results in real time.

You can change a shader variable value only for a specific 3D model/geometry item. No programming is required. Imagine passing a variable objColor with value (1,1,1,1) to a shader in a constant buffer. You can change that variable's value before rendering a specific item:

Workspace

You can modify SHADERed workspace however you want to thanks to Omar Cornut's great work on Dear ImGUI's docking branch, which implements window docking.

Code editor

SHADERed has a built-in code editor. The code editor features a very basic version of code predictions. It is called Smart predictions and it will be updated and improved over time. It also has very basic version of autocompletion (inserts/removes brackets) and automatic indenting. All of these features can be turned on/off in options. Theres also an option to convert your tabs to spaces. The code editor will be improved over time.

You are not forced to use the built-in code editor (and you probably shouldn't use it right now to avoid some annoying bugs). You can seperately run your favourite code editor and SHADERed. Modify your shaders in the code editor of your choice and just save the file - SHADERed will automatically recompile the shaders for you.

Error markers

Error markers help you locate and identify your shader errors more easily. Hover over a line with an error to see the message or just check it in the "Output" window.

Custom themes

You can create your own theme SHADERed theme. Modify ImGuiStyle members in an *.ini file. SHADERed themes allow you to customize everything including text editor color palette. SHADERed comes with a few built-in themes. I am bad at designing so please submit your own themes!

Want to create your own theme but don't know how? Visit TUTORIAL.md.

Custom templates

You can create your own custom templates. SHADERed comes with a GLSL, HLSL and HLSL deferred rendering template. Templates help you start developing shaders quickly. To create your own project template, paste your project directory in /templates directory and name your project file template.sprj. You have to reopen SHADERed if it was already running to see the template under File -> New. A menu item for creating a template will have the same text as the parent directory of the template.

TODO

There are also some features that I am looking to implement:

  • multiple cameras
    • this feature would allow you to render same scene from multiple angles
  • shader variable pointers
    • currently if you want to have same value in two shader passes you will have to enter the values manually
  • node shader editor that can export to GLSL and HLSL
  • shader & theme "store"
    • a place where you can upload your shaders or themes and see other peoples creations
  • "Export as DirectX/OpenGL application" option (.cpp file)
  • compute and tesselation shaders
  • render your shader to a video file
  • support #include and macros
  • buffers read from file or built using in-app buffer editor
  • magnifier tool & pixel inspector
  • text geometry
  • debugger
  • built-in FXAA

Except those large features, I am also planning to do some small QoL changes:

  • feature such as "Change variables" for items but for changing textures -> render textured 3D models easily (have an option to set up everything automatically)
  • add "Advanced" menu that allows user to modify (at least some) system variables when taking screenshot/video
  • program crashes on invalid input layout (+ probably other invalid inputs too)
  • cubemap preview
  • click on cubemap, audio, 3d model, texture and render texture preview should open a preview window
  • recompile the shader after we change shader path in a shader pass
  • when adding a shader pass, decompile the shader and detect the input layout + input variables
  • when loading a texture it might not be loaded if not bound to any shader pass
  • indent controls after fps in the status bar - bad UX and UI
  • ability to change warning, message and error text colors
  • add a */ImGuiWindowFlags_UnsavedDocument to Pipeline (and add '*' to window titlebar) after changing anything in the project (+ popup window on exit)
  • PipelineUI::GetSelectedShaderPass() -> add Geometry and other options under "Create" menu item in GUIManager
  • use an icon font instead of buttons like "U", "D", etc...
  • toolbar (a bar with all the important tools (icons))
  • shift+drag with right click to move ArcBallCamera focus point
  • add an option to disable certain shader pass
  • find and replace in code editor
  • right click in code editor
  • improve the overall code (enum for shader type, etc...)
  • fix memory leaks
  • undo/redo adding shader items
  • languages (english, croatian, etc...)
  • switch from sdl to sfml (?)
  • dragging items from one pass to another, duplicating them, etc...

Credits

Huge thanks to Omar Cornut, go follow him on twitter or support him on patreon. I dont think SHADERed would exist without his awesome library Dear ImGUI. I came up with the shader editor idea when I stubmled upon a ImGuiColorTextEdit. So big thanks to BalazsJako for his amazing creation. Also, thanks to Raph Levien for the Inconsolata font and Christian Robertson for Roboto Mono.

Thanks to Khronos for creating glslangValidator and SPIRV-Cross tools. Those programs allowed me to add support for GLSL. Thanks to AMD and their RenderMonkey examples. Credits to creators of the themes that SHADERed comes with. Those themes and their creators can be found here.
