Model Outline

[pusia1]

I want show osgEarth::ModelNode Outline.

I tried like this.

but did not apply.

`
m_rpModelNode = new osgEarth::ModelNode(pMapNode, style);
const char* VS =
"#version 330 compatibility \n"
"uniform float outlineWidth; \n"
"void main()"
"{ \n"
" vec4 clip = gl_ModelViewProjectionMatrix * gl_Vertex; \n"
" vec3 normal = normalize(gl_NormalMatrix * gl_Normal); \n"
" normal.x *= gl_ProjectionMatrix[0][0]; \n"
" normal.y *= gl_ProjectionMatrix[1][1]; \n"
" clip.xy += normal.xy * clip.w * outlineWidth;\n"
" gl_Position = clip; \n"
"} \n";

	const char* FS =
		"#version 330\n"
		"uniform vec4 outlineColor; \n"
		"void main() \n"
		"{ \n"
		"    gl_FragColor = outlineColor; \n"
		"} \n";
	osg::Program* program = new osg::Program();
	program->addShader(new osg::Shader(osg::Shader::VERTEX, VS));
	program->addShader(new osg::Shader(osg::Shader::FRAGMENT, FS));

	osg::Group* outline = new osg::Group();
	osg::StateSet* outlineSS = outline->getOrCreateStateSet();
	outlineSS->setRenderBinDetails(1, "RenderBin");
	outlineSS->setAttributeAndModes(new osg::Depth(osg::Depth::LESS, 0.0, 1.0, false));
	outlineSS->setMode(GL_CULL_FACE, 0);
	outlineSS->setAttribute(program);
	outlineSS->addUniform(new osg::Uniform("outlineWidth", 0.002f));
	outlineSS->addUniform(new osg::Uniform("outlineColor", osg::Vec4f(0.0f, 0.7f, 0.0f, 1.0f)));
	outline->addChild(rpModel);

	osg::ref_ptr<osg::Group> rpRenderModel = new osg::Group();
	rpRenderModel->getOrCreateStateSet()->setRenderBinDetails(2, "RenderBin");
	rpRenderModel->addChild(m_rpModelNode);
	

	rpRoot->addChild(rpRenderModel);
	rpRoot->addChild(outline);

`

How can I Show Model Outline?

osg version 3.6.0
osgEarth version 3.4

Does your code work with a normal OSG model? (outside of osgEarth?)

[pusia1]

you're right.
When using only osg without using osgEarth, the line is visible normally.
