This article proposes a solution to a common problem in CAD applications: saving a bitmap for each leaf node in an assembly.  The suggested method is based on Eyeshot's assembly navigation system, so it is recommended that you read the article Assembly Navigation first. Our Pulley Transmission article is used to build a sample scene: The assembly tree contains so…

A 3D mouse is an input device used by some CAD users. After a 3D mouse is detected for the first time, whenever the user right-clicks on an Eyeshot control with their (standard) mouse the normal shortcut menu is repopulated with navigation options specific for 3D mice. Please be aware that Eyeshot controls do not react when the "MENU" button of your 3D mouse is pressed. T…

Starting from Eyeshot 2023 the EntityGraphicsData class is abstract. This article explains the recommended approach for creating an instance of the concrete class in a custom Entity. For a complete sample, you can see the SelectTriangle source code. To create an instance you should override the Entity.InitGraphicsData() and use the RenderContextBase.Creat…

Eyeshot offers the possibility to enable multisample anti-aliasing (MSAA), a technique that removes the artifacts known as jaggies from the raster image of a 3d scene. It can be activated like this: design1.AskForAntiAliasing = true; // in the Form/Window constructor design1.AntiAlisasing = true; This technique greatly improves the image quality, however, in eyeshot…

Sometimes it is convenient to get a rough estimate of the 3d position of whatever is under the mouse cursor. It is possible to get that information by reading the depth value corresponding to the mouse screen location.  The method Workspace.ScreenToWorld() does exactly that. The following code sample demonstrates how you could use this approach to show an arrow a…

  Ambient occlusion is a shading and rendering technique used to calculate how exposed each point in a scene is to ambient lighting (source: Wikipedia). Starting from Eyeshot 2023, it is possible to enable the Screen-Space Ambient Occlusion effect (SSAO): a fast approximation of ambient occlusion computed in real-time.   Settings SSAO settings are accessed through t…

Starting from Eyeshot 2023, it is possible to detect and draw silhouettes by leveraging the computational power of the GPU. To enable this feature you should set the relative property:  DisplayModeSettings.SilhouettesDrawingMode = silhouettesDrawingType.ImageBased;   Benefits Fast Independent from the polygon count Limitations Silhouettes are detecte…

devDept Software is proud to announce a new Eyeshot 2023 Beta build. Having now completed several migrations, we have a final Workspaces architecture that no longer requires Design/DesignUI separated objects. This initial design didn’t allow full customization, as we discovered when migrating actual customers’ applications. We then introduced the Documen…
