I want to deform the shape of a complex 3D model in an iOS app, is there a way scene kit allows you to deform a mesh around a point or similar? If not what is the best way to create this kind of effect? I have a mesh with armature in Blender, can I use this?

I am pretty new to WPF and want to use the 3D rendering options in WPF. For this I need to write custom shaders for my 3D meshes. I searched a lot, but haven't found anything related to 3D. I only found the ShaderEffect, that can be used for 2D graphics. So is there any way to do this? Maybe by looking on how the DiffuseMaterial or other Material work?
I have the following setup: I can track a surface very accuratly in a 3d space using a tracking system. Now I want to project on this plane with an overhead projector.
I want to develop my interface in WPF/XAML and then render it in real time to the surface that is tracked. But I don't know exactly how to do it...
This is what I think: I need to model the tracked surface in a 3D space, then I want to develop the interface using regular WPF/XAML controls use (maybe) directx to render these controls to model in 3D that represent the tracked surface.
I already found information of using directx in combination with wpf (Sharpdx.WPF) but here they demonstrate how to create 3d scenes with wpf... However, they don't show how to use regular WPF controls and render these to the 3d models.
Do I first need to convert the user control of WPF/XAML to an image and then render it to the 3d model or is there another way to do it?
I'm using 3d in WPF and want to save it to a 2d image file, kind of screen shot.
What's the best way to do that ?
In his 12 days of WPF 3D series, Eric Sink has a nice post about Rendering a WPF 3D scene to a Bitmap. Also of interest might be the post on Printing support.
And for any WPF 3D user, I highly recommend the (open-source) Helix 3D Toolkit, which has several importers and exporters to different formats, and is an essential WPF 3D companion library.
I am considering using Silverlight for a project I am working on. This project will need to show a 3-Dimensional cube. Is this possible in Silverlight?
I see a lot of examples that a basically 2-sides of one item. Kind of like a sheet of paper. Is this what "perspective" 3D is? How is perspective 3D different than normal 3D?
Thank you!
You should look at Kit3D for Silverlight. Someone also created a silverlight3d.com site, but it current just has three reference articles and a link to Kit3D.
It is also possible to emulate 3D as demonstrated by this MSDN article.
The feature that was added in Silverlight 3 is referred to as "perspective 3D" to avoid confusion that might arise with someone expecting it be some kind of full scale 3d rendering API (like DirectX or OpenGl etc.) or something like WPFs UIElement3D.
The "perspective 3D" feature in Silverlight allows you to take any regular 2D UIElement and rotate it in 3D dimensions; you can think of it like a more powerful RenderTransform. There are two ways of setting a "Projection" on a UIElement, with a PlaneProjection (simple) or with a Matrix3DProjection (more complex).
You could certainly use this feature to create a 3D cube, where each face of the cube is a UIElement with a Projection applied to it. However you would not use this feature to create something that required complex 3d models such as a 3D game.
I am trying to port a WebForms app to Silverlight, this application is using the GDI Graphics class to draw polygons to a in-memory bitmap, it will then do pixel by pixel comparisons so I need access to the pixel buffer.
Example:
Graphics g = Graphics.FromImage(bmp);
g.FillClosedCurve(brush, points, FillMode.Winding);
I have done some serious googling trying to figure out how to draw polygons and then be able to access the pixel buffer of the canvas surface. My findings indicate that this is not possible with the WPF silverlight graphics, so I need to use a custom graphics library but have only found some 3D libraries. Is there a simple 2D library for silverlight or should I just go a head and write a polygon render algorithm myself?
If you write a polygon rendering algorithm for Silverlight, it would have to be all managed code, I haven't seen any examples of this, but if you write one let me know, I've been looking for something like the for XNA.
Silverlight 3 should be adding some of the things you need to make this a lot easier like rendering to a texture and accessing a bitmap at the pixel level.
Could you grab an image from a server and process that? You could dynamically generate the image and you'd have access to whatever you needed outside of Silverlight.
