helix-3d-toolkit

问题 Follow-on question to this one. I am trying to generate and save a series of images. Rendering is done by Helix Toolkit, which I am told utilises the WPF composite render thread. This is causing problems because it executes asynchronously. My original problem was that I couldn't save a given image because it hadn't yet been rendered at that time I was trying to save it. The above answer provides a workaround to this by putting the 'save' operation inside an Action which is called with low

问题 C#, WPF, Helix Toolkit. I am trying to generate a bitmap from a HelixViewport3D and have encountered a few problems. The first problem is that I cannot find a way to render off-screen. There are a few references to this online (e.g. here) and as far as I can see it does not have a built-in solution. As a somewhat sub-optimal workaround I have proceeded to render to the screen where the user can see it, with the intention of creating a bitmap from that rendered image. I now have the problem

问题 I am new to WPF, and am trying to build a 3d viewport with helix toolkit. The viewport, grid etc show up as expected, And I add a simple tube.

问题 I want to draw a set of 3D-Cubes, each Cube should display a name and also should have its own event handler when the cube is selected. Is it possible to implement it using code behind or xaml binding? 回答1: To draw a 3D cube from code behind I would use the Helix3D toolkit CubeVisual3D. However if you want to stick with stock WPF 3D elements it is fairly simple to implement. start here to Learn about Text in 3D enviroments http://www.codeproject.com/Articles/33893/WPF-Creation-of-Text-Labels

问题 I am trying to build an obj file viewer using Helix Toolkit (https://github.com/helix-toolkit/helix-toolkit) with SharpDX. So far I am able to load an object file and render it's contents to Helix Viewport3DX. Model looks good with some obj files but for others there are some lightning problem and back surfaces are always black. I am not sure what am I doing wrong. Is this light problem due to the fact that SharpDX does not support back materials?? Please help. Problem using Helix Sharp DX:
