[osg-users] How to prevent OSG linking against Desktop OpenGL

2016-09-09 Thread Daniel Neos
Hi, my Applcation mainly uses Qt(with QOpenGlWidget) and OpensceneGraph, thus it relies heavily on OpenGL. Since the Remote Desktop Protocol(RDP) poorly supports OpenGL, there is no trivial way to run my application over Windows Remote Desktop. Hence, I choose to use Softwarerendering as a

[osg-users] Get openGL version with the Help of osg

2016-08-04 Thread Daniel Neos
Hi, In my application, at the very first beginning, I want to check which openGL version the user has before creating/doing anything openGL related. For example the user can have a very poor openGL version(or remote Desktop only supports openGL 1.1), then I want to check the openGL version

[osg-users] Improvement of Arcball Camera Handling

2016-07-21 Thread Daniel Neos
Hi, I want to improve my CameraHandling since it acts a little bit odd if I am too far in the center of the scene, which is the lookat-point of the camera. The camera is rotates around a specific point(mid of the boundingsphere center), always looking at it. But if I am getting to close to

[osg-users] Visibility of Vertices

2016-07-08 Thread Daniel Neos
Hi, is there an easy way to determine whether a single vertex is visible or not, i.e. no other object is blocking the line of sight? My problem is that my geometry does not consist of solid objects or planes, just a lot of single vertices. I want to be enable to pick a point reliably by a

[osg-users] Keep Geometry always visible withtout occlusions

2016-07-06 Thread Daniel Neos
Hi, I have a scene consisting one geometry node. This node contains 2 geometries. One of them has a lot of vertices, color are bound per vertex. The other one is a single vertex, but set with a point of the size of 15, basically it is just a 'fat' vertex. This servers as a marker. This marker

[osg-users] Realtime Pointpicking

2016-06-24 Thread Daniel Neos
Hi, I have a Pickhandler and a dynamically changing scene which consists only of a geometry node. To be more specific, the geometry node represents a point cloud consisting over ~10 vertices. Using a line intersector makes it nearly impossible to get an intersection, but the Intersector I

2016-05-16 Thread Daniel Neos
Hi everyone, I have implemented a Cameramanipulator by myself, because I need more individually control over the camera in the scene, like rotating around a specific axis. I let osg compute the Boundingsphere of my scene and set the rotationpoint and the lookat-point or center-point at the

Greetings everyone, I am trying to display a point cloud, consisting of vertices and color with OpenSceneGraph. A static point cloud to display is rather easy with this guide. But I am not capable of updating such a point cloud. My intention is to create a geometry and attach it to my viewer
