[osg-users] How to draw 3D cylinder and 3D band?

Happy New Year, everybody! I’m Daven Hem, OSG beginner in Cambodia. I want to draw 3D cylinder and 3D band which is made from centered line. I have two problems I have to solve with OpenSceneGraph. Create a 3D line which is defined by N vertices. - Create a 3D cylinder which is

Re: [osg-users] Draw vertex as Circle with color given by some Vec4 array

Hi Bruno, As I am recalling how this is to be done is something like this: Let say you want to pass colors as vertex attributes: const size_t vertexAttribLocation = 5; osg::Vec4Array* colors = new ... osg::Geometry* geometry = new ... geometry->setVertexAttribArray(vertexAttribLocation

Re: [osg-users] Check if sampler2D is valid in fragment shader

Hi, yes there is: Simply assign one Program with shaders handling texturing and the non-texturing variant at the appropriate state-sets. Be sure to share the programs (don't create a new one per instance) to keep performance up. I can create a minimal example if you're stuck with this.

Re: [osg-users] Check if sampler2D is valid in fragment shader

Pragmatic shader composition was added to the repository around Feb 13, 2015, and most likely into OSG 3.4 and newer only. A link to the relevant thread started by Robert Osfield is here: http://markmail.org/message/mjxjn4vujpvz3wfz#query:+page:1+mid:vogwv7uwhoefcln6+state:results 2017-01-03

[osg-users] code for merging tri strips in a cache friendly way

When loading .obj files (e.g. exported from Blender) into OSG - especially those that are exported with the "group by material" option - you might find a lot of individual tri strips in the resulting OSG geometry. Here is a piece of code (a node visitor) that will join these tri strips into a

Re: [osg-users] Draw Instanced intersections

Hi Bruno, There is simply no geometry in the scenegraph to intersect (or strictly speaking there is only one drawable) Instancing takes away the load from the CPU to the GPU,which on the OSG-side means to put the instanced geometries into one drawable containing the instancing information.

Re: [osg-users] Draw Instanced intersections

Hi, Oliveira, there maybe many reasons that why no intersection. I cannot give you advise without more information. u can check about examples within OSG source code, e.g. "osgintersection". -- Cheers, --- TianZJ At 2017-01-03 17:55:02, "Bruno Oliveira"

Re: [osg-users] Draw Instanced intersections

Hi TianZJ, Thanks for the quick answer. I checked the intersector, but intersector->getIntersections() returns no intersections at all. 2017-01-03 9:32 GMT+00:00 tianzjyh : > Hi, Oliveira, > You can check the intersections of your intersector(e.g. >

Re: [osg-users] Draw Instanced intersections

Hi, Oliveira, You can check the intersections of your intersector(e.g. LineSegmentIntersector::Intersection), and you will find they contain an "osg::NodePath", which means the whole path of the node(e.g. matrix transform nodes upon the drawable instance). -- Cheers, --- TianZJ At

[osg-users] Draw Instanced intersections

Hello, I'm implementing a draw instanced optimized scene. This is for drawing a set of polygons. Previously I was creating a drawable for each polygon, but now I am using draw instancing. With one drawable per polygon I can easily use osg intersectors for computing scene intersections. But how
