My problem now it's that i can't get Mouse3DDown to working. I am missing something? Is it not possible to hitTest a billboard?
Another question, is it possible to change ScreenSpacedGroup3D's default camera? I would like to try an orthogonal camera instead.
Lunci
@holance
@artipo Currently billboard does not support hit test in screen space group yet. Will need some time to implement the hit test for it.

Hope to get your answer @ Gravemind2401
@Gravemind2401 You need to tune the depth bias to avoid z fighting.
Hello, I'm using the component process of Gis to load Google maps section of ellipsoid, the different layers of the biopsy, after treatment, the depth of the calculated error problem may cause the depth buffer, through access to information, I found that you can use the logarithmic depth buffer, to adjust the depth to solve this problem, but I did not found in the components of the depth of description, the position of the sources are vec4, but the position of the component is vec3, so what is the component of the depth of the attribute name?
Where is the depth of the model stored?

Perfect, thank you for the info!

Is there a way to set or measure the size of a SpatialTextItem? I'm trying to make something like a chess board in 3d -- which will be completely flat -- and put a custom text in each tile of the board. The TextDemo gives a general idea how to do that, and I can control the height of the text shapes via TextGroupVisual3D.Height, but I can't figure out how do I control the width too (I'd want the text to scale to best fit a tile).

Is there some way I can subscribe to changes in Visibility for Element3D objects in code behind? Seems a bit complicated with the DependencyProperties.
Lunci
@holance
@kthyholdt There's a Visible Changed event in scene node you can hook up.

Ive added "helix-toolkit-wpf-SharpDX" to my project and I'm trying to use a viewport3DX. I've added lights and camera to my viewport but the viewport is showing a blank black screen. I've not added any effects manager to my Viewport3DX. Is it necessary to add an effects manager to the viewport for the viewport to work and display models? If yes how do I add an effects manager to a viewport 3DX?
SwaroopSomanna
@SwaroopSomanna
Ok so I've added default effects manager as shown below:

@SwaroopSomanna
And it's still showing blank screen

Ok now the viewport is working during runtime but in the designer it stays blank black

Hi! Does anyone here have experience with the topic of reducing polygon number? I want to apply it to simplify my model using Helix Toolkit using those algorithms.
Here is a link to a related paper: http://pds26.egloos.com/pds/201402/12/11/gdmag.pdf
Thanks!

Does anyone know how to add a grid bed to the ViewPort3DX?

Hi, what is the unit system in viewport3D, is it mm/cm/m? and can I change the unit of the viewport? Thank you
Lunci
@holance
@atlesg There's no such thing as unit defined in helix toolkit. You need to define the unit yourself and do a transform on your data for helix toolkit to render.

Hi guys, Im new to HelixToolKit and i wanted to know if it was possible to animate an imported object using Helix Toolkit?

I don't think it's possible...

Hi, I want to create a coordinate model on MouseDown whenever I click on the model. I already got the Point and Normal Vector from Raycast -> Triangle Facet. I did create Arrow model: Point 0 = position -> Point1 = position + direction |length of arrow|. Howevers, I don't know how to apply that to create a coordinate model CoordinateSystemVisual3D*

I guess we must kinda do some transformation since every created coordinate model is at the orgin 0,0,0

Helixtoolkit sharpdx version supports basic animation.

@atlesg You need to apply a translation transform to move your coordinate model to the location.

@holance Could you provide any reference link for the same. Thank you for your reply.

Hi, how can we longer the arrow length of the CombinedManipulator? I can only make the diameter bigger. Thank you!

@Shreyasj96
@holance Thanks. I checked it out. It's awesome..
Shreyasj96
@Shreyasj96
@holance But the code is bit complicated for beginners to understand. I didnt understand how all the values of NodeAnimations were populated. Was it done using an external software like 3DS Max or something similar?
Lunci
@holance
@Shreyasj96 Yes, it's done by other software. Helix toolkit only reads animation from model files.
Shreyasj96
@Shreyasj96
@holance Hmm..Perhaps, it would be better if there was a tutorial on how to make it step by step and even better if there was like a HelixToolKit Start to Finish Udemy course. Definitely would pay to learn the tricks.
Tai Le
@atlesg
There is no way to scale up the combined manipulator :( I'm giving up
Lunci
@holance
You can copy the manipulator source code and modify yourself. @atlesg

Hello, how can we serialize our nested objects that include WPF 3D components inside (ModelVisual3D, Model3D...). I tried Json Newtonsoft but every time I serialize, I got a StackOverFlow error.
Is Json the correct path to go? Or I need to seek for something else? My goal is to:

1- Save a scene, with lists of objects inside, so next time I start the app I can import back the scene with my objects (they are declared globally).
Thank you!
2- Save a list of objects, so I can later import into a parent object.

Hi! I've notice only now your message!
THANK YOU VERY MUCH! I wasn't expecting some work from you!
After the holidays I was even thinking of asking help to contribute myself to fix these problems.
Anyway I'll try to give you feedback as soon as I can.

I'm trying to test your fixes, sadly I don't know how to get the compiled dlls.
I've tried to retrieve the nightly build from the "Nightly build" link in the Readme.md but it appears to be broken.
I've also tried to clone the code and compile it myself, but I get lot of dependencie missing errors, althought I didn't tried to much.
Lunci
@holance
@artipo add the nightly build Link as an nuget source in your visual studio.

Hey all, I've been working alongside Nordaj to implement morph target animation for Helix. He's just submitted a PR. This PR allows for morph targets (aka blend shapes). And models that contain blend shapes no longer crash helix (woo!). The pr is up.
Lunci
@holance
@robotron2084 I tried the demo, seems like the morph from the model is not obvious enough to verify the result. I can't tell where the morph is happening during animation. I disable the morph and the demo is running exactly the same using only skeleton animation.

SharpDX WPF:
I am looking for the best way to toggle between one finger rotate and one finger pan. The method can not use additional keys. Something like a conditional ManipulationBinding?
Lunci
@holance
@bugbiter Currently the touch behaviors are hard coded in camera controller class. They do not support manipulation binding.
Chris Hill
@robotron2084
@holance that is odd. The demo should show the model talking. Are you not seeing that?
Lunci
@holance
@robotron2084 I am not seeing the model talking. Only open the mouth a bit
Are you seeing differently on your side?
