David: It's equivalent to this C++ code:

for (size_t i = rightpenumbra.sections.size() - 1; i < blockerLine.size() - leftpenumbra.sections.size() + 1; ++i) {

    Vert &vert = blockerLine[i];

    umbra.sections.push_back(Umbra::Section(vert, extendDir(0.5 * (leftpenumbra.sections.last().direction + rightpenumbra.sections.last().direction)));

}

Hi, great tutorial.
But I’m having some troubles converting it to C++.

Would you mind converting this line to me, I can’t understand the loop, begins where and finishes where?

foreach(ref vert; blockerLine[rightpenumbra.sections.length-1..$-leftpenumbra.sections.length+1])
umbra.sections ~= Umbra.Section(vert, extendDir(0.5 * (leftpenumbra.sections[$-1].direction + rightpenumbra.sections[$-1].direction)));

I’m also having some troubles on other parts but for now this would help a bunch. I’ve placed my email on the form.
Thanks

Cool stuff, any chance to download c++ code for it?

Christian: Thx for the reply :). Dont worry, i got it working just enough to achieve what i want.

Thank you. Your sample codes really helped me in trying to achieve the effect. I would have no idea how/where to start by just reading orangy’s article.

Cheers :)

Jim: While porting the prototype can be a fun exercise, a lot has changed in the last years. You could probably achieve the same effect much more efficiently on modern graphics cards.

Unfortunately I don’t have the time to help debug your problem. Start small, build things step by step and test everything along the way.

Hi, Im just wondering if youre still active or not. I am currently in the process of porting the prototype to c++, but im having trouble in getting the blending to work, thus the shadows dont work.

Would be great if you can help.

FYI, great article. Helped me a lot :)

I’m sorry, but I do not have a working version of the C++ port Damian did. If someone ports it again and releases the source, please drop me a line so I can add a link!

Hello, where can I get the c++ port of the code?
I really wanted to try it out.

Best regards and excellent work!

Ok. Thanks for your response and interest to my request.
