This isn't as pretty as other projects, but might be useful for some, it's available here.

This is a side project, which I'm calling ImControl. One pushes transformations to a stack and then places control points which can then be dragged. The key point is that the transformations depend on parameters (passed as pointers) and dragging the control points feeds back to these parameters. One doesn't have to worry about how to do this, all the vector calculus / linear algebra happens in the background.

The API is still in flux, but here is the code for the arm example for anyone interested (edit: best to check out the repo, linked above):

static float base_rotation = 0.0f;
static float base_angle = 0.1f;
static float elbow_angle = 0.2f;

// Begin the viewport, filling available space
ImControl::BeginControlPointView("arm", { -1, -1 }, { 1, 1, 1, 1 });

// Push projection and camera matrices
ImControl::PushPerspectiveMatrix(45.0f / 180.0f * 3.14159f, ImControl::GetControlPointViewAspectRatio(), 0.01f, 10.0f);
ImControl::PushLookAtMatrix({ 0.0f, 0.9f, -1.5f, 1.0f }, { 0, 0.5, 0, 1 }, { 0, -1, 0, 0 });

ImControl::PushRotationAboutY(&base_rotation);  // Rotate arm

ImControlPointFlags flags = ImControlPointFlags_DrawControlPointMarkers | ImControlPointFlags_DrawParamDerivatives;

ImControl::ControlPoint({ 0.2f, 0, 0, 1.0f }, &base_rotation, flags, 0, 0.0375f, { 1, 0, 1, 1 });  // Controls Rotation
ImControl::StaticControlPoint({ 0.0f, 0, 0, 1.0f }, flags, 0, 0.025f, { 1, 1, 1, 1 });  // Demarks base of arm

ImControl::PushRotationAboutZ(&base_angle);  // Rotate arm up and down
ImControl::PushStaticTranslationAlongY(0.5f);  // Move up to next joint

ImControl::ControlPoint({ 0.0f, -0.1f, 0.0f, 1.0f }, &base_angle, flags, 0, 0.025f, { 1, 1, 1, 1 });  // Control points along arm
ImControl::ControlPoint({ 0.0f, -0.2f, 0.0f, 1.0f }, &base_angle, flags, 0, 0.025f, { 1, 1, 1, 1 });
ImControl::ControlPoint({ 0.0f, -0.3f, 0.0f, 1.0f }, &base_angle, flags, 0, 0.025f, { 1, 1, 1, 1 });
ImControl::ControlPoint({ 0.0f, -0.4f, 0.0f, 1.0f }, &base_angle, flags, 0, 0.025f, { 1, 1, 1, 1 });
ImControl::ControlPoint({ 0.0f, -0.0f, 0.0f, 1.0f }, &base_angle, flags, 0, 0.0375f, { 1, 1, 1, 1 });  // Control point at joint

ImControl::PushRotationAboutZ(&elbow_angle);  // Bend the elbow
ImControl::PushStaticTranslationAlongY(0.4f);  // Move to end of arm

ImControl::ControlPoint({ 0.0f, -0.1f, 0.0f, 1.0f }, &elbow_angle, flags, 0, 0.025f, { 1, 1, 0, 1 });  // Control points along forearm
ImControl::ControlPoint({ 0.0f, -0.2f, 0.0f, 1.0f }, &elbow_angle, flags, 0, 0.025f, { 1, 1, 0, 1 });
ImControl::ControlPoint({ 0.0f, -0.3f, 0.0f, 1.0f }, &elbow_angle, flags, 0, 0.025f, { 1, 1, 0, 1 });
ImControl::ControlPoint({ 0.0f, -0.0f, 0.0f, 1.0f }, &elbow_angle, &base_angle, flags, 0, 0.0375f, { 1, 0, 0, 1 });  // Hand controls two angles

ImControl::ClearTransformations();
ImControl::EndControlPointView();  // Parameter changes are made here

elbow_angle = clamp(elbow_angle, 0.3f, 2.8f);  // Clamp angles after view ends
base_angle = clamp(base_angle, 0.1f, 1.4f);

@ocornut do you think that it'll be good to open next threads like this in "Discussions" section from now on? I think they'll fit better there.

[ocornut]

Presently I think "Discussions" have missing features (no labeling) and biased design (no way to mark as resolved without stupid scoring/gamification) so at this mind I am not even sure I want Discussions, I'm just hoping Github will at least add the labeling otherwise they are not worth using ihmo.

The biggest set back for me (and couple of others) which prevent us to use ImGui in production for our players is how limited its text rendering is and the lack of support for complex text layout (shaping, bi-di, etc). This is because the majority of my players write in Persian (which is basically the Arabic script)

So I've searched on google and from #1228 I knew I had to implement this myself.

So I went ahead and did.

I had to heavily modify ImGui's freetype integration, in fact glyph range and merge mode no longer work because when you do text shaping, you have to load all the glyphs, some of the glyphs are not mapped to any codepoint since they are ligatures.
Then I had to rewrite almost every part of the text rendering functionality resulting in triple the amount of the current code written for text rendering.
There are many caching and tricks in place to prevent shaping and other stuff in each frame.

2021-06-14_05-27-23-PM.mp4

Word wrapping was not easy to get right... Since I fully support bi-di texts, word wrapping is quite complicated and there wasn't much resource about this online.

And if that wasn't enough

2021-06-14_05-31-29-PM.mp4

stb_textedit is not meant to do RTL or at least I haven't seen anyone use stb_textedit for RTL input widget. So I spent a good amount of time making stb_textedit work alongside RTL and bi-di text.
The blinking cursor was also very complicated to do and selections are no longer just one rectangle for each line and as you can see in the video, although there's still a single Stb.select_start and Stb.select_end, multiple portions of text are being selected and it's because of bi-di. I've also added right align to input widget.

Honestly this wasn't an easy task and since ImGui's codebase was not ready for this I had to heavily edit ImGui itself.
I've also separated the atlas for each font and the font texture get built in another thread (async load) so it will no longer block the rendering thread. (This wasn't required but I did it to speed up the loading)

Open source libraries used: HarfBuzz (for shaping), SheenBidi (for bi-di text), FreeType

[ocornut]

@0x416c69 This looks amazing!
It's a big thing and instead of discussing it here, I would suggest that you post all of this in a new Issue + ideally post a link to the sources/fork/mods so we can get an idea of whether this would be possible to get some of it main line (even partially). I understand you went through caching the shaping and other stuff, it's going to be good to have that as a refernece.

(PS: We've been working on a rework of InputText() which among other things should simplify the selection rendering code (current one is tricky because it is interleaved with two other things, for the sole purpose of not having to iterate the buffer multiple times, new version maintain a line index meaning none of the slow seeking at required anymore meaning that code is simplified)

[0x416c69]

@ocornut Thank you.

I'll have to refactor the code first since it's pretty messy right now. I'll put the link to the repo in the newly created issue: #4227

It aims at fast prototyping small applications where performance does also matter.

Flexible Example:

    from p3ui import *

    ...

    widgets = ScrollArea(content=Flexible(
        width=(100 | percent, 0, 0),
        direction=Direction.Vertical,
        align_items=Alignment.Stretch,
        justify_content=Justification.Start))


    ...

    widgets.content.add(ScrollArea(
        width=(200 | px, 1, 0),
        height=(200 | px, 1, 0),
        content=Image(texture=Texture((imread(test_png_path.as_posix()) * 255).astype(np.uint8)))
    ))

Been working on a custom PCB emulator the past few days. Here's a button, an LED and an UART pin header connected to an emulated RISC-V controller. Didn't do much fancy yet with ImGui but it was once again super helpful to quickly build a nice interface for the whole thing :)

Code currently running on the RISC-V Core:

#include <types.hpp>

void print(const char* string) {
    char *UARTA_TX = reinterpret_cast<char*>(0x5000'0004);

    for (const char* s = string; *s != 0x00; s++)
        *UARTA_TX = *s;
}

int main() {
    print("Hello RISC-V!\n");

    volatile u8 *GPIOA_CR = reinterpret_cast<volatile u8*>(0x6000'0000);
    volatile u8 *GPIOA_IN = reinterpret_cast<volatile u8*>(0x6000'0004);
    volatile u8 *GPIOA_OUT = reinterpret_cast<volatile u8*>(0x6000'0008);

    *GPIOA_CR = 0b10;
    while (true) {
        if (*GPIOA_IN == 0b01)
            *GPIOA_OUT = 0b10;
        else
            *GPIOA_OUT = 0b00;
    }
}

So hello, people! It is rare nowadays to see DearImgui being used as actual game interface. So I went ahead and used it for MonogameJam3 jam. The topic was "low budget". So I used the library not only for making tools but for making GUI itself!

I've seen a few audio processing plugins (VST) posted here, so here is another one :) I wrote it for KVRs semi-annual Developers Challenge. It's loosely based on an old guitar pedal that was given to me by my dad. It's both a fuzzbox and a compressor that can pump like crazy with the right settings. Try it on drums and other dynamic material with the amount up all the way and tweak the speed and gain knobs for some grainy pumping ;) You can find some audio examples and download the binary (windows and linux) here https://www.kvraudio.com/product/nb01---distortion-sustainer-by-noizebox-industries

The UI is all Dear ImGui with custom widgets for the knobs and level meters, and a modified GLFW as platform backend. It uses thread-local ImGui contexts and one drawing thread per instance to provide multiple, separate editor instances.
