Hey all,

I am developing a next iteration of my GFX engine (previously called CalderaD) and I am looking for help from the community to get some feedback on compilation instructions (any other feedback is very welcome as well as well as code quality).

What can you do to help ?

Please clone the repository, and try to build it on your system. Currently it shoudl build on Linux and windows 64bit. but since I don't have a Mac available it would be great to get some feedback on that as well.

Please let me know any issues that you have (either here or via a Github issue)

The repository lives here: https://github.com/DannyArends/DImGui

(I know the name is chosen poorly, I'll probably change it in the Future to CalderaD, and get rid of the previous iteration)

Some highlights of the engine:

  • Using importC to bind to SDL, Vulkan, and CImGui
  • Uses GLSL shaders for rendering
  • Has a Compute Shader pass rendering to a texture
  • Basic objects (triangles, squares, cubes, particle engine)
  • Renders PDB proteins and has a 3D Turtle on top of an L-system
  • Basic loading of Wavefront objects

Hope this is allows, and thanks in advance for your feedback

Haven't tried it yet, but from the first glance look what is missing:

  • example folder: with easy to run as "dub run" code (at least for supported and tested platforms)
  • screenshot for Readme.md - showing how the final result should look like

Thanks, I added a screenshot to the readme.

What do you mean by example folder ? Currently the engine has a single scene.d file, which loads all objects in one go. Do you mean having multiple dub.json files each loading / setting up different scenes ?

Oh it's already kind of a working example.
I thought the main code is just a library to be used in other projects as a dependency.

Indeed, the basic compile is doing a working example of the engine, the scene setup is eventually supposed to be provided by the user of the library.

Again many thanks for the feedback :)

I guess it's because I failed to clone submodule(s)

```bash
user@host:~/workspace/DImGui$  git submodule update --init --recursive

Could you use not git protocol but https one? I can easily clone using latter:
```bash
git clone https://github.com/cimgui/cimgui.git

Hmm, that is weird, I just added it using a

git submodule add

Let me see if I can update that, never really worked with git submodules before

Should be solved in commit: 86259698fd24be5f2fbad5fbcfe9ae4d1f416f01

Thanks for trying it, and reporting this.
Let me know if it works now :)

Thank you! The problem is fixed. Now I need to install other dependencies, I'll do it later
