@stiangglanda
Hi i am currently implementing skeletal animation using directx and i use a left handed coordinate system
stiangglanda®
@stiangglanda
I have two questions first since i need to transpose every matrix (bone offset in my case) do i need to do something to rotation vector 4, position vector 3 and scaling vector 3 maybe swap y and z?
stiangglanda®
@stiangglanda
And second I don't know what the transformation in aiNode does i thought it meight be(for the bones) the bone offset but since the data isn't the same tis can't be true or is it scalingpositionrotation already calculated?
Edit: scaling x position x rotation

@ushort
@AndreiDespinoiu Thank you, was very informative. Unfortunately, my "bones" do not have a hierarchy. I simply have a group of vertices and the transformations for each frame. Is this supported in assimp?

Hi, quick assimp question: https://stackoverflow.com/q/70575859/1131467

Heyyo, how do I actually compile Assimp with a program?
I don't actually understand how to do so, as my program requires assimp.lib and mesh.h, however, assimp.lib doesn't exist.

I'm trying to use the MSYS make provided in the MinGW Windows Installation to little avail. It's worked for the most part, but the issue I'm having is I don't know what I am doing.
Kim Kulling
@kimkulling
Hi
@tomazos Hopefully my answer on github helped you a little bit.
@GeneRickUsername Which kind of program? Do you want to integrate Assimp into your own application?
And please post your issues

i just did the build and the lib folder only has a .lib and no .dll
can you help me know why that happened

You can d
Find the dll in the bin folder

Hi Im trying to cross-compile ASSIMP for devkitARM for the 3DS. I know this probably isn't a supported thing to do however the main problem I come across is contrib/zlib/CMakeFiles/zlibstatic.dir/compiler_depend.make:4: *** multiple target patterns. Stop. when I try to compile ASSIMP. However, if I manually go into the zlib directory and run cmake then make it works fine and compiles without multiple target patterns. Anyone here know how to fix this multiple target patterns issue?
Kim Kulling
@kimkulling
You can configure cmake to use your own zlib. maybe that could help you
And hi
Jsut check the cmake-file in the root folder. there is one switch for using a global zlib

Hello. I'm looking for advice on using the latest version of Assimp with C# in .NET 5.0. I have been able to use 4.x and 5.0.1 with the Nuget.org package called AssimpNet but I wonder if anyone has made an update to target 5.1.x? I tried reaching out to the developer on BitBucket but got no response so I thought I'd ask here just in case. Is anyone currently using Assimp 5.1.x with .NET 5.0?
Kim Kulling
@kimkulling
I think we need to update the assimp.net wrapper
At this moment, the latest versions are not available.

hey hey
how do you guys build the viewer?
having issues with fbx files with animations
Kim Kulling
@kimkulling
you need to enable the build for it when generating the project files.
And you have to keep in mind: the viewer will only work on windows
you can create it via: cmake CMakeLists.txt -DASSIMP_BUILD_ASSIMP_VIEW=ON
This will generate projectfiles for the viewer on windows

Hi, I have the same question as @PiKeyAr, is there someone working on the Assimp .NET wrapper? I'm trying to export files to gltf2, but the gltf2 output in AssimpNet 4.1.0 is not up to the glTF standards and shows errors on opening in https://gltf-viewer.donmccurdy.com/
I have also tried the 5.0.1 beta package, that one works well for the gltf2 exports. But the issue here is that the application crashes after every export. I have tried the AssimpNet wrapper (both 4.1.0 and 5.0.0-beta1) with the newer Assimp releases. But those are not compatible anymore with Assimp, at least not for exporting to gltf2 files, starting from version 5.1.x and up.
I would of course prefer to use the newest version of Assimp with the C# wrapper so have all the latest fixes for gltf2 included. So I am wondering if someone is still working on it / will pick it up and if yes, is there any indication about when we can expect it? Or if it's better to set this idea aside for now and maybe try to pick it some other time.
Kim Kulling
@kimkulling
Hi
I guess not. I tried to update this package but saw a looot of build failures. So I was not able to solve them at this moment
So if someone is interested in working on this, feel free!

hey kim, been auditing my assets bought from the unity store and I found that the fbx file's position vertices has been imported X,Z,Y instead of X,Y,Z. This was found after converting the original file into collada. Is there any flags in assimp to manipulate vector component order?
Rebecca
@beckylum0216
the second issue is that the indices from the original fbx when compared to the indices after they were imported into blender don't match up. The import from blender rendered the model, the data from the original fbx would not render correctly
Kim Kulling
@kimkulling
Hi @beckylum0216
Are all vertices rotated or is the global coord system of your model rotated in such a way?
4 replies
Maybe some rotations has applied after importing the asset? Normally we will not touch the xyz components of our positions.
Rebecca
@beckylum0216
hey kim, further auditing was done and it seems like the library is generating malformed vertices, something is not being initialised. I can post the log file for your reference.

Hi Kim, I'm using 5.2.0 to export and all the file formats are working fine, apart from the glTF ones (both gltf, glb & gltf2, glb2)... Is there anything different within the 'aiScene' that i need to set for these formats? The exports are failing with aiReturn_FAILURE.

Many thanks!

Hi
Do you have a small example which can be used to reproduce the issue?

Hi,

Would you like a zipped project or code snippet?

Hey guys, is anyone know how should I get the material parameter from the library? I made some parameter, except the diffuse color= base color(from blender), for the other, it not looks same(like specular , roughness etc)
