This is Part 3, I am splitting issues to reduce loading times and avoid github collapsing messages.

Browse all threads and find latest one to post to using the gallery label.

I'm making a game called Re:creation (more info here).
Here are some in-game dev tools I've made with ImGui!

I've also made ImGui SFML binding and wrote two articles about ImGui (Part 1, Part 2)

UI mockup for an asset library/manager I'm working on. Nothing functional as we speak :)
Built mostly by re-using code from omar (obviously), dougbinks, juliettef, itamago, simon geilfus, krys and flix01.

Exciting times indeed!

Edit: @ratzlaff: used http://blog.bahraniapps.com/gifcam/ to encode the gif :)
Edit: @Flix01: it's Google's MaterialDesignIcons actually! (fixed-size icons are much better to work with!)

[Flix01]

@r-lyeh Awesome main menu! And awesome icon font (or probably awesome usage of "Font Awesome" ?!?)
:)

Edit: @r-lyeh: good to know that Google's MaterialDesignIcons are fixed-size! "Font Awesome" is a bigger set AFAIK, but their size is not always the same, and this can result in visual problems (for example with check boxes where the width of the unchecked and checked icons is not the same).

@bkaradzic nice ! is this anim tool somewhere on your github repos ?

[bkaradzic]

@damqui Nope, but all default settings for that UI are in bgfx repo.

An unfinished (just the GUI ATM), very bad looking, Sudoku game for Dear ImGui:

[phoenixcatdog]

Testing Imgui with native cocoa(no external dependencies) and opengl3(Working on Metal version).

[edin-purkovic]

Working on my 3D Model Editor/Game Engine, currently fixing my docking code and some bugs, for the most part it works.. imgui makes it very easy and beautiful looking...

This is sneek peak of node editor build on top of ImGui. It handle displaying and user interaction.

ImGui can be bend to handle zooming while keeping crisp details.

[jarikomppa]

Squee! Please say the sources are/will be available?

@jarikomppa Right now source isn't out there. I will think about making it open source.

[Flix01]

@thedmd I knew you were making awesome stuff! :)

ImGui can be bend to handle zooming while keeping crisp details.

How?

[Edit:] Is this something related to your branch named: 2016-09-fringe-scale, and expecially this commit: thedmd@94dd233 ?
Is it easy to use ?

[DrJedikiah]

I've edited ImGUI a lot, and i solve the AA issue thanks by the way it was about renderer. I changed my hook to Present[17] from EndScene. And this is dll file not exe.

I made this tab system with buttons, i swapped the system of active state. If tab is active, button stays active too.

[thedmd]

@Flix01: You're correct. Branch 2016-09-fringe-scale is related to my solution. I'm scaling content of draw list vertex buffer. When zooming in finge is also magnified. To get rid of that I scale it by inverse of zoom factor. This is basic idea. I will post some code as an example when I get to my PC.

[Flix01]

@thedmd Thanks.

[thedmd]

@Flix01: In more detail. To achieve scaling choose some scale factor, set fringe to 1 / scale factor and draw as normal. I'm drawing on multiple channels to achieve layering but this isn't necessary. After drawing is done call ImDrawList_TransformChannel_Inner and voilà, you are done. Almost.

This works but some problems arise around it. Working with global coordinate system (GCS) when scaling is involved isn't best experience. Treating your child window as canvas which works in local coordinate system (LCS) is much easier. (0, 0) is in top left corner of child window. I advise to use matrices to represent transformation from one space to another from the start.

First thing is transforming ImGuiIO::MousePos and ImGuiIO::MouseClickPos to LCS. This will allow ImGui to handle input correctly.

Second. Push new clip rectangle which cover visible part of your canvas. When scaling down canvas is larger than actual window, input is clipped to window size in GCS. Pushing larger clip rectangle enable ImGui to handle larger areas. Whole scaeled area isn't visible yet but since MousePos is transfomed ImGui is actually processing input over whole area.

Third. Be ready to restore ImGuiIO::MousePos and ImGuiIO::MouseClickPos to original values and bring them back to LCS. It is necessary if you want show popups correctly.

Last thing to be done is to transform window draw list to make content actually visible. You can use ImDrawList_TransformChannels for that. If you want to write similar function by yourself make sure one vertex is transformed only once. If everything inside window is scalled, good. You can just transform vertices. If only some channels are drawn in LCS things are more tricky. Include code handle former.

If something is unclear or language I use is odd, please point me that out and ask questions.

static void ImDrawList_TransformChannel_Inner(ImVector<ImDrawVert>& vtxBuffer, const ImVector<ImDrawIdx>& idxBuffer, const ImVector<ImDrawCmd>& cmdBuffer, const ImVec2& preOffset, const ImVec2& scale, const ImVec2& postOffset)
{
    auto idxRead = idxBuffer.Data;

    std::bitset<65536> indexMap;

    int minIndex    = 65536;
    int maxIndex    = 0;
    int indexOffset = 0;
    for (auto& cmd : cmdBuffer)
    {
        int idxCount = cmd.ElemCount;

        if (idxCount == 0) continue;

        for (int i = 0; i < idxCount; ++i)
        {
            int idx = idxRead[indexOffset + i];
            indexMap.set(idx);
            if (minIndex > idx) minIndex = idx;
            if (maxIndex < idx) maxIndex = idx;
        }

        indexOffset += idxCount;
    }

    ++maxIndex;
    for (int idx = minIndex; idx < maxIndex; ++idx)
    {
        if (!indexMap.test(idx))
            continue;

        auto& vtx = vtxBuffer.Data[idx];

        vtx.pos.x = (vtx.pos.x + preOffset.x) * scale.x + postOffset.x;
        vtx.pos.y = (vtx.pos.y + preOffset.y) * scale.y + postOffset.y;
    }
}

static void ImDrawList_TransformChannels(ImDrawList* drawList, int begin, int end, const ImVec2& preOffset, const ImVec2& scale, const ImVec2& postOffset)
{
    int lastCurrentChannel = drawList->_ChannelsCurrent;
    if (lastCurrentChannel != 0)
        drawList->ChannelsSetCurrent(0);

    auto& vtxBuffer = drawList->VtxBuffer;

    if (begin == 0 && begin != end)
    {
        ImDrawList_TransformChannel_Inner(vtxBuffer, drawList->IdxBuffer, drawList->CmdBuffer, preOffset, scale, postOffset);
        ++begin;
    }

    for (int channelIndex = begin; channelIndex < end; ++channelIndex)
    {
        auto& channel = drawList->_Channels[channelIndex];
        ImDrawList_TransformChannel_Inner(vtxBuffer, channel.IdxBuffer, channel.CmdBuffer, preOffset, scale, postOffset);
    }

    if (lastCurrentChannel != 0)
        drawList->ChannelsSetCurrent(lastCurrentChannel);
}

@thedmd thanks again for your detailed explanation.
It's something I'll investigate further in the future... (I still have to find out how antialiasing works...).

P.S. I'd also like to manage the draw lists to see if sorting indices on a texture-id basis is worthy or not.

@ocornut : sorry for having asked questions in the "Screenshot" section.

[thedmd]

This is from a weekend project ascii-renderer where ImGui is used to control how rendering works. Only grayscale now. Everything is rendered on CPU.

And yes, you can render ImGui to ASCII buffer. : )

[vassvik]

I'm using LumixEngine's docking extensions, as so many others are, to make an editor-ish thing to be mainly used for my simulations. I wanted to create a minimal project with just the essentials to have a decent looking docking example with as few dependencies as possible, so I removed all the things I didn't need from LumixEngine's docking files and replaced it with simpler things.

Current work-in-progress code

@thedmd Please release the source, I'm very interested in node based editors like this!

@ExtasyHosting Slick! :)

This is kind of a meta suggestion, but you can simply link here on each screenshot thread so you don't have to update the description each time.

Correct, but the direct links are 1 click away instead of 2 so it is more convenient for the user :)
