Hi David, tesselation shaders usually work on the GL_PATCH primitive rather than usual triangles. So in order to get your program running you need to run a visitor on the scene and convert the primitive sets to this. This however won't magically solve every tesselation problem, but this a

Re: [osg-users] [build] When writing my own software and integrating openscenegraph, LNK error is thrown out.

Hi Diwas, Can you be a bit more specific on the Linker error you are getting? It is hard to guess what might be missing without some output and maybe some minimal code. The only thing I'm spotting is the /MDd. Have you tried /MD instead? Cheers Sebastian Hi, I will explain what I did till

Re: [osg-users] Support for sampler arrays

Hi Chris, Following Lionels reply I did a quick test which seems to work: void addSamplerArray(osg::StateSet* ss) { osg::Uniform* uniform = new osg::Uniform(osg::Uniform::INT, "test",2); uniform->setElement(0,0); uniform->setElement(1,1); osg::Texture2D* tex1 = new

Re: [osg-users] Support for sampler arrays

Hi Chris, Hi, Working on an app that is going to be doing a lot of work with large texture processing, and will need to squeeze as much data into graphics memory as possible and allow many textures to be referenced programmatically. I've got texture arrays working, but can't use this for all

Re: [osg-users] Vapsxt instrument insert into Osg?

Hi Zhangfa, I don't know the specific product, but usually you can wrap the "draw" of the 3rd-party into an custom drawable and use the drawImplementation to execute the libraries code. Set setUseVertexBufferObjects(false); setUseDisplayList(false); Also you should structure your call

Re: [osg-users] Running OSG models on OpenGLES2.0

Hi Hyun, Hi Chris, I tried most of examples. Now I'm focusing on glsl_simple.osgt as it looks simple, but only the second row of shapes shows. If I modify the vertex shader a little, I get to see both first/second row. Can you tell us which platform you are using? You usually don't have to

Re: [osg-users] 16384x4096-Textures and 8192x8192-Textures

Hi Peter Hi, i´m wondering why OpenSceneGraph-Viewer can view 16384x4096-Textures but not 8192x8192-Textures. This totally depends on your GPU/Driver. Usually 8192x8192 can be displayed by any modern GPU. When OSG encounters an image with a size over the limit reported by the driver it will

[osg-users] Mutliple viewers with multiple scenes

Hi, I've got some abnormal usage-pattern of viewers and scenes in one application. There is some Qt-based application using OSG to render different scenes into individual widgets(which use an osgViewer::Viewer), which kind of works. The problem is mainly due to osgDB::Registry being a

Hi Michael, Unfortunately this will render the geometry three times. First shadow map depth pass, Second to create the screenspace shadow texture and for the RTT again. Any idea how to prevent the second pass and move it to some later stage? Cheers Sebastian Hi. I have the sample that

Hi Tony, It happens for the mailing list too (I guess the reply-mail for the forum post is related to the duplication to the mailing list). It seems that you get one every time you post something of the forum. I posted two things tonight and got two of these. Tony

Hi Pierre-Jean Hi, I try to port my app from Linux to Mac OS (El Capitan) using OSG 3.2. I wrote a simple system of shaders to apply a texture on a model: Vertex shader : Code: attribute vec4 osg_Vertex; uniform mat4 osg_ModelViewProjectionMatrix; varying vec4 texCoord0; void main(void)
