Compilation problem

[pemsley]

Hi Mark,

I tried to compile... but failed - I am not sure if this is my old compiler or your code. (Apple LLVM version 6.1.0 (clang-602.0.49) (based on LLVM 3.6.0svn))

Thanks,

Paul.

Hi Paul,

Sorry for taking so long to reply. I think my compiler implicitly casts std::string to a C-style string there, so I didn't catch it. I'll make a PR shortly to fix that.

Also, there currently isn't any documentation on how to actually use the engine, so I'll upload a demo project to a new repo and link it in the README here (until I get around to actually writing docs - planned to be within the next few updates!).

Thanks for the heads up! Mark

Hi Mark,

I am the author of a molecular graphics application representing protein models and cryo-EM reconstructions (that is in part what it does). I am interested in improving its looks - and that's how I discovered your Vulpes-engine.

This is how it looks now (with fixed pipeline graphics):

https://www2.mrc-lmb.cam.ac.uk/personal/pemsley/coot/web/screenshots/coot-gleevec-page.html

The model primitives are 3D points with a color index (atoms) and lines between 2 3D points (bonds). The density/mesh is just a list of lines between points (or triangles).

I'd like to represent the density with some sort of glass effect, rather than the triangular mesh.

Thanks for the (future) demo.

Regards,

Paul.

Sorry again for the late reply - I just finished my final exams.

Your application looks very interesting, but I don't think Vulpes Engine is a suitable fit for it (yet). In particular, it doesn't support transparent materials and it isn't entirely easy to implement it due to the rendering technique I chose.

If you're looking for a C++ library that can render in 3D, then you might want to check out Ogre3D or Irrlicht which are more feature-complete engines (there are many others which are easy to find, too). Godot also has C++ but I don't believe you import it as a library. If the language doesn't matter then Unity would be your best bet (especially considering the size of the community - you would get a lot of help).

I'll leave this issue up until I fix the code in the meantime. Let me know if you have any questions!

Should be fixed in #6 - thanks for bringing this to my attention!

[pemsley]

thanks.
