Re: [osg-users] How to draw 3D pipe?

Hi, Trajce Nikolov Thank you for your kind instruction! I want to learn more from you in future. Bless you and your body. Thanks. Daven Hem -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=69248#69248

Re: [osg-users] How to draw 3D pipe?

Hi Daven, found the code that might get you started. It uses simple geometry shaders to draw 3D pipeline from a set of points interpolated by catmull rom spline https://groups.google.com/forum/#!topic/osg-users/o8ovoo271lA Havn't checked the code now, but I am sure it will work - it worked then

Re: [osg-users] How to draw 3D pipe?

Hi, a)-c) is pretty easy and can be a good task to learn a bit of geometry shaders. I did this long time ago and it was not that hard. Might get you some code if I find it in the email archive. That might helps d) can you clarify more. I have seen this thing with physics and there are companies

[osg-users] How to draw 3D pipe?

Dear, Sir I’m Daven Hem in Cambodia. Thanks for your reviewing. We are currently developing new mineral prospecting aided software for local workings. I have to develop 3D VIEWER which can render 3D work place realistic on its screen. On our workings, there are many pipes, including internet,

[osg-users] how to draw 3d pipe

hi all, I know this problem is not so related to OSG, but there is no better place I can find. What I want to draw is to draw a three-dimensional pipe from a 3d curve with a given radius.The pipe I mean is alike a cylinder,but it is bent. any ideas? thanks in advance.

Re: [osg-users] how to draw 3d pipe

Hi forest, I have done this several times in order to simulate springs. If you have the 3D trajectory, you will also have or you can compute the tangent vector (the one that follows it). For every point in the trajectory, you place a point r units away from it and in a perpendicular direction
