I am a newbie on Itwin platform. I exported a Revit file to iModelhub using Itwin synchronizer. Is it possible to view the revit 2D drawings/sheets in Itwin viewer besides the 3D? If yes, how? Thanks.

I was making some library functions for using the camera in OpenHarmony for the JS API. When I used the tag in the HML file, the Previewer couldn't load it. Moreover, DevEco Studio 3.0.0.900 doesn't support emulators, so I have no other way to test those functions. How should I deal with this?

I am trying to add three.js based 3D objects to a PDF page. It seems there are no direct exporters available to do that. So I am trying to do the below thing,
Convert the gltf/stl/obj files to U3D files
Add the .u3d file to PDF page.
I am trying to do the below process and I am not sure whether this approach is possible. It will be a great help if there is any support available to do any one of the below conversions. Also if you know any other possible approaches, kindly update me!!
Input formats output format
GLTF
OBJ U3D
STL
(any
three.js supported
3D formats)
Thanks.
There are few options available to export the three.js graphics to a PDF ( static content not a dynamic U3D assets)
Static contents
Get the rendered data from the three.js webGL renderer / canvas renderer using toDataURL("image/jpeg"), change the MIME type to JPG/PNG and add the resulting stream as an image to PDF ( this worked for me)
example - https://plnkr.co/edit/Ty8BZaDcflCJH5tH?preview
Like the above approach we can use three.js svgrenderer to export the renderer contents into a SVG data stream, which can be added into the PDF ( textures, mesh may not be 100% reproduced)
The legacy API - "threejs-pdf-renderer" can be used to directly export the three.js animations to a PDF. We don't need any other dependencies to create the PDF. But this is a legacy API which uses legacy three.js version, lot of effort needs to be done to make the API to be compatible with the latest three.js version.

Dynamic 3D contents
We can export the three.js animations into a U3D file (no direct support is available as for now), this U3D file can be directly embedded into PDF.

So I'm getting the error "TMX: unsupported compression method" using this tutorial's code and any of my own created TMX tiled map editor files.
I was just trying to figure out how to use tiled to make interesting maps, since I am creating a side scrolling game I was using this as a reference.
Any help would be appreciated :)
Tiled has multiple compression modes for saving - under File -> Preferences -> Store tile layer data as: for iOS and Box2D, this should be set to Base64 (gzip compressed).
I have a project in which I would like to programatically create and render a 3d animation based upon input. I originally asked here on stackoverflow if Blender was right for the job, and the response was yes, but upon looking at the API, it says this:
Python was embedded in Blender, so to access BPython modules you need to run scripts from the program itself: you can't import the Blender module into an external Python interpreter.
I want to be able to create and render this scene without having to ever open another program like Blender. Is this possible, and is Blender still the right choice?
Thanks in advance!
At work me and colleague worked on a project that rendered 3d scenes altered externally. We used Python to modify/create scenes, and did the rending on server through the command line interface (no GUI).
You can pass a python script as an argument to Blender in the command line options to
generate your scene objects and do the rendering.
I don't see how you can render in Blender without using Blender.
You can use Blender if you want, obviously this is not your only option.
If you need to
create and render a 3d animation based upon input.
You can go as simple or as you complex as you'd like.
You can use OpenGL in your language of choice (C++, Java, Python, etc.)
and display the animation (with or without fancy renderings).
It's up to what 'render' means to your context.
If you need some nice shading(light, soft shadows, reflections, etc. - ray tracers basically), you can still show an interactive preview to your users and generate the scene
for a 3rd party renderer(like Yafaray, Sunflow, LuxRender, etc. - I've put together a short list of free renders), and show the progress to the users after they've chosen the external render option.
On a similar note, have a look at joons.

I want to convert html to pdf dynamically in objective c.
what is the best way to convert it, so that it maintains its look same as html.
Thanks in advance.

UIGraphicsBeginPDFContextToFile will help you to create a PDF file which shows your web content. Read through the documentation and create your own solution or just follow the tutorials I found:
Convert Html or UIWebView to pdf in iPhone or iPad
Making a PDF from a UIWebView
I have used this Haru open source library, it is quite simple and useful for creating pdfs http://libharu.org/wiki/Main_Page
Objective-C is a programming language, it doesn’t know anything about HTML or PDF per se. How to do this depends on the framework you’re using. I’m assuming here you’re using Cocoa on OS X.
There you can load your HTML into a WebView provided by WebKit and then use the NSView method dataWithPDFInsideRect: to render it as PDF. I haven’t tested this, but maybe you’ll have to add the web view to a window before you can query the PDF data.
