I'm trying to carefully word this question because the problem doesn't appear to be that the animation isn't being imported. I can see the animation as <untitled animation> in the scene graph, and I can play the animation in Xcode; the issue is then locating the animation as an attribute to any of the objects. This is what I can see in the scene graph:
But, when I try and locate the animation here:
... nothing appears. So, it seems that it isn't importing the animation as a CAAnimation object with a key.
I have tried to programmatically enumerate through the child nodes to find any CAAnimation objects, but it doesn't see any. Other scenes work perfectly however.
What do I need to add to the DAE file to get it to build the CAAnimation object properly?
Worth pointing out that the 3D model and animation was exported from 3DS Max using OpenCollada. I don't know what the best practices are for exporting collada to SceneKit, and if anyone has any useful information that would be great. Apple don't seem to have anything.
The SceneKit editor in Xcode does not display the root node in the scene graph view, and it might be the one that holds the animation.
You should be able to retrieve the root node's animation programmatically.
I am trying to script a setup where the map borders is set to something specific after smoothing the geo in the viewport. I don't know how to call upon that attribute or change it.
It's under smooth mesh - extra controls in the GEOShape of the mesh.
Any ideas?
Mel or Python... I dont care, I just need to know how to reach these? :-)
Open up the Script Editor, and turn on History > Echo All Commands
Also open the Window > General Editors > Attribute Spreadsheet.
From the All tab, find Keep Map Borders.
As you change the radio button between Do not smooth, Smooth internal, and Smooth all, you'll see the value in the Attribute Spreadsheet change between All, Internal, and None.
Type All in the Attribute Spreadsheet, and look over at the Script Editor. You should see this line:
setAttr "pCubeShape1.keepMapBorders" 2;
That is the MEL command that sets Map Borders to Do not smooth
I have a video playing of lines being drawn on the screen. Is it possible to create a pixel shader (for WPF) that turns newly colored pixels a certain color for N milliseconds?
That way, there can be some indication to the user to movement on the screen when the lines don't move often and the user isn't always looking at the screen.
You can use DirectShow. Its written in unmanaged code, so you need to use this wrapper DirectShow.NET in order to use it in your C# application which is running in managed environment (samples are included, even with EVR which stands for Enhanced video Renderer which means MUCH better video quality). And when you will be passing a control handle to wrapper method for setting the video output, you need a WinForms control, because only from them you can get your desired control handle. That WinForms control you can then host in your WPF application using the WindowsFormsHost control provided for such situations when you need to use some WinForms control(s) in a WPF application. Its just theory, so i dont know if its an ultimate solution for you.
BTW: The whole idea is based on fact, that DirectShow is just some query constructed from separated filters. Renderer is a filter (EVR, VMR-7, VMR-9). Sound player is a filter. And they are connected through their pins. Its like a diagram. Electronic schema or something like that. And you can put for example Grey scale filter in there. And voila, video output will be greyscale. There is a bunch of tutorials for that. And completed simple filters as well. Unfortunately, filters must be written in C++:(
PS: I never said its gonna be easy:D
I'm working on a module that displays DWG files in WPF. I've managed to use CadLib library but it's working very slowly and I want to make it faster. I found out that if I convert that DWG file to SVG format and then print it to my XPS printer and rename the file to ZIP, I can get .page file which is basically a XAML file that displays the original SVG object in XAML.
I want to display this XAML code on a custom control and be able to pan / zoom it around. I tried to place this XAML code in a Canvas and it did manage to show up there, but now I'm stuck trying to pan / zoom the shape that was drawn there. Also, the mouse events are fired only when you click the actual drawing itself, and not the Canvas, which will be hard for the user to click...
Any help would be highly appreciated :)
You could try creating nested Canvases : One that holds the vectors and is moved on demand, one that is fixed and serves as the viewport. Haven't tried that, but it should be feasible...
If i have a logo, let's say done as a jpg or even a png. Any suggestion for how I can use that to define a path geometry? It would be really good if any suggestions could be provided for how i can do it in blend.
Thanks
Yes - I just tackled this problem for an LOB application two days ago.
I can't offer advice for Blend (though I've read that it can be done in Expression Designer). However, the best free tool I've found for this is called InkScape (http://www.inkscape.org).
It's opensource, and while it's intended primarily for editing SVG vector-based images, it has two key features that are useful to us WPFers:
It can vectorize (i.e. "trace") raster images like bitmaps and jpegs, albeit not as well as one would hope, and
It can export the vector image as XAML
You'll invariably find that you get better results from loading vector formats (like SVG, EMF, WMF, etc) and saving to XAML, than if you try to convert a bitmap/jpeg... simply because the process of vectorizing a raster image is error prone at best. So if you want to bring a company logo into XAML, try to get hold of the source files used to create the logo (perhaps done in Illustrator?) and import that into InkScape.
If this post is helpful, please be kind and give it a one-up.
Jasema is a terrific tool right for the job.
Also, don't be shy to use Blend - it is somewhat more difficult to use (drawing shapes using pen) but it gets easier pretty fast. Switch on gridlines and optionally snap to them for good results.
What both Jasema and Blend are lacking, is the ability to easily create shapes with a central symmetry (like stars), so I took parts from Jasema and created my own tool (named Radius) that works a bit like a combination of a ruler and compass.
I have a good idea but you're png, bmp, jpg or other non vector file is must be very simple because we need best scan results and only use inkscape.
Step: Drag and drop your file workspace on Inkscape, download free.
Tip: If your image is color white, Top menu item File->Document Properties-> heck Checkerboard Background and if you want uncheck Page border show.
Step: Top menu item Path-> Trace Bitmap-> Mode check what you want property, i usually use color property and if your file is png check Remove Background then click OK, then wait again Ok button is Enable and close window.
Step: Now you have a two layer, top layer vektor file and bottom layer your file. Select vector file and top menu item Edit-> XML Editor-> select svg path and look side column, d name propery in your data path value.
But this method may not always work or may not give the desired results and draw your own shapes with the scape so you can get the path data from the XML editor.
Example, my first tests this like:
and after working on it some more:
I've solved my problem (export an image as XAML) using Microsoft Expression Design 4 (Free Version). I've downloaded from the link
http://www.microsoft.com/en-us/download/confirmation.aspx?id=36180
As input, I had Adobe Ilustrator files.
Adobe Illustrator / CorelDraw is perhaps the best tool out there for these operations that I have used.
Personally, I prefer illustrator for on-screen media. These tracings can be exported into several formats such as EPS, SVG, AI, or even XAML (with this plugin)
Best of Luck !!!!
I have recently been struggling with this myself. I had a set of icons done in data and needed to update them to look nicer.
I tried everything, manually typing them out. drawing in svg, converting svg to xaml.
in the end i found a list of open source icons from google material icons.
I then used this to convert from the svg files to data
https://github.com/BerndK/SvgToXaml
It works well but not for the icons i drew myself.
I decided to place all the icons data i convert into an app i built myself that will give you the data and a preview of the icon. feel free to use and contribute. I will keep updating as much as i can.

Convert your image from png to svg in online converter, then drop file into this site http://inloop.github.io/svg2android/ and you will see pathData of your image like below shown in my image.
