A Swift library for graph visualization and efficient force simulation.

Hi, I’m Zhen.

I’m interested in visualization, human-computer interaction and programming languages. Sometimes I tinker with typography and graphics.

I love Pokémon games. If you spot a laptop with 4 pixelated Pokémon stickers on it, that’s mine.

Would you share you visionOS app to our Demo Share Platform

Hello, I am Zhang Siqi, the person in charge of SwitGG and XReality.Zone.

Events hosted by these two communities have been officially recommended by Apple multiple times, and you can still find our SwiftGG: WWDC.Playground event organized this year on the Beyond WWDC official website.

I am reaching out to you because I heard that you have a demo for visionOS. Would you be interested in publishing it on our visionOS app exchange platform?

Application Exchange Platform: https://github.com/XRealityZone/Let-us-xrOS/blob/main/README.md
Application Data Repository: https://github.com/XRealityZone/XRApps/blob/main/README.md

Here is a brief explanation of why we are undertaking this project.

With the release of Apple Vision Pro this summer, the era of spatial computing is upon us, inspiring tech enthusiasts and developers to think about crafting unique three-dimensional applications with new interactions, systems, and hardware.

Since the WWDC 2023 keynote, social media has been abuzz with stunning visuals and demo videos of visionOS apps, but due to the Apple Vision Pro not being officially released yet, it's difficult for us to try out other developers' creations.

To address this, we have developed the Let’s xrOS app, which allows you to test out visionOS apps from other creators in the community, giving you early access to the charm of spatial computing devices.

We hope this tool will enhance the frequency of exchanges between developers and promote the growth of the entire community.

I look forward to your response!

Wishing you all the best!

P.S.: Please do not publicize this app and data repository yet. Let's wait for our official announcement tomorrow, and then you can help us promote it. For now, my main objective is to gather some developers' apps to generate interest in the store!

To Publish `/docs` to GitHub Pages

Hi, @li3zhen1

I think there's something wrong with publishing the "docs" folder, so I share my solution here:

The documentation should be published on the path: /documentation/grape

https://li3zhen1.github.io/Grape/documentation/grape

If the documentation doesn't appear on the path, please check the publish condition on the repository settings:

1. Got to Settings > Pages > Build and deployment
2. Set Source to Deploy from a branch
3. Select Branch to main, /docs
4. Click Save

[SIMD] Use any(mask) instead of comparing zeros

Comparing .nan always returns false

Dragging nodes does not work on iOS

Several of the examples include the ability to drag nodes. When built for macOS, the nodes can be tapped (clicked) and dragged. When built for iOS, only tapping works.

I discovered this first by incorporating this library in my iOS app, then adding handlers as documented. I spent a long time trying to understand why I could only get onNodeTapped to work, adding and removing handlers to see if they made any difference. I was not able to understand why by reading your code, but I assume I just missed something.

I eventually decided to build and run the examples project on macOS, then on an iOS simulator. This is when I discovered that they do not perform the same.

Any ideas what might be causing this?

Thanks, Wilson

需要帮助，无法实现3d视图中拖拽与点相连的圆柱体

我是一名没有基础的代码小白，我想实现在Grape的3D例子中的拖拽效果，但我仅仅只能实现对球体的拖拽，在拖拽后该怎样使圆柱体重新定位与小球相连。求大神指教，万分感谢！

Make the view scrollable / pan to move

Thanks for your great work!
Is it possible to make the view scrollable, i.e., make the view larger than the screen and use pan and zoom to navigate around?
I tried to wrap the view inside a scrollview, but without success.
Also, the pinch to zoom gesture seems to be buggy.

Thanks again for your support.
