GlslOptimizerV2

GlslOptimizerV2 is an optimizer for the glsl language with support of last opengl api and Stages Vertex \ Tesselation Control \ Tesselation Evaluation \ Geometry \ Fragment

Based on Mesa3D and glsl-optimizer

Pay Attention, for the moment this app is full of bugs and can crash in any reason.

Why ?

Some time ago i found the original glsl-optimizer, but this project is stopped since a while and without support of Tesselation and Geometry shader stage nor last Opengl Api.

After analysed it a bit, i discovered than most of the Optimization code is coming from Mesa3D Implementation. So after a bit of search, i decided to create an updated version of Gsl-Optimizer who can support last stages and last Opengl api too.

All this work is mostly based on Mesa3D and original Glsl-Optimizer, but all not work porperly for the moment. I not guaranty than generated optimized shader can compile

I have exposed the most of params i have found in Mesa3D for better optimization possibilities, and proposed a GlslOptimizer module and an standalone App for optimize in an easy way your shaders.

I am very interested in graphic programming but as a self-learning guy, im in no way an expert.

So if you feel like it, help me improve this Software that I make available in open source for that.

Get started :

1. Open the App :)
2. Open a shader file( you have many samples in dir shader_samples) or create new (in the main menu bar)
3. Set the type of shader, The version of glsl you want, and Tune the parameters.
4. Optimize

To note :

All the settings are saved in a conf file in the same directory of your shader file the conf file name the name and ext of your shader file with an extention conf : If you have a shader like : shader.frag => the conf file will be shader_frag.conf

So for the next time, you just need to open your sahder file again, (dont opn conf file) and your settings will comming back :)

The module GlslOptimizerV2 :

The module GlslOptimizerV2 is inside the directory GlslOptimizerV2

There is a CMakeLists.txt file for link into your porject easily

The Standalone App :

Some screenshots of the current app :

Open You file :

Write/open your code and optimzie it : (see in the pane, all the params i exepose)

Customize the style ( the default theme is light but you can also customize app theme and editor palette)

Library used :

• Glfw - ZLIB
• Dear ImGui - Docking/tables branch - MIT
• Glad - MIT
• tinyxml2 - ZLIB
• ImGuiColorTextEdit - MIT
• dirent - MIT
• cTools - MIT
• ImGuiFileDialog - MIT
• Mesa3D - MIT (all the optimisation code come form it, but just the compilation code is extracted)

Based on :

• glsl-optimizer - MIT (glsl generation is based on it)
