Include textured models

[marcoma9023]

Good morning,

I need to integrate 3D models of any format into my scene, I have no limitations, for example OBJ, STL, 3ds.

Previously, with OSGEarth 2.x I had no problems and each model was created with materials with color and/or texture applied.

I know that under GL3 everything is handled with shaders.

I need to understand:

1. What format for a 3D model is usually used with OSGEarth 3.x?
2. If the OBJ goes well, do you have a shader ready to handle materials?

Thanks for your attention

If you load your models through OSGEarth it will typically run them through a shader generator.
If you load them with OSG directly, you will need to do it yourself either by using the API (osgEarth::ShaderGenerator) or by using the shadergen pseudo-loader, e.g.

osgDB::readRefNodeFile("model.obj.osgearth_shadergen");

Hope this helps.

I usually load the model with osg through the osgDB::readNodeFile() call

but, in case my OBJ contains materials, I have warnings that they don't know how to handle materials and the model color is black.

I tried doing as you suggested, then calling the ShaderGenerator, but the model is black.

What am I missing?

I have the same problem... the ShaderGenerator is not working... use the ".osgearth_shadergen" to have your model fully textured.

Hey sorry for the late reply. Can you provide an example model that we can use to test?

[devil-darkside]

Use the cow.osg from "OpenSceneGraph-Data" and the code in #2328

Resolution in #2328.

Hello, I am currently encountering another issue. I am using osg3.4 and osgearth2.7, osg:: Node * pNode=osgDB:: readRefNodeFile ("cow. osg") or osg:: Node * pNode=osgDB:: readNodeFile ("cow. osg") to load cow.osg, and then using the method osgEarth:: Registry: shaderGenerator(). run (pNode); My pNode node is mounted under an OSG:: Group node, and then OSG:: Group is mounted under the Earth node. The opengl version is compiled using opengl3. There is a problem with the following image
