Hi, You just need load some two textures here is the code
osg::Program* program = new osg::Program; geometry->getOrCreateStateSet()->setAttribute(program); char vertexShaderSource[] = "varying vec2 texcoord;\n" "\n" "void main(void)\n" "{\n" " gl_Position = ftransform();\n" " texcoord = gl_MultiTexCoord0.xy;\n" "}\n"; char fragmentShaderSource[] = "uniform sampler2D baseTexture; \n" "varying vec2 texcoord;\n" "\n" "void main(void) \n" "{\n" " vec4 CHROMA_KEY = vec4(1.0,1.0,1.0,0.1);\n" " vec4 color = texture2D( baseTexture, texcoord); \n" " // ARUNA ROX I DID IT hahahaaaaa. THE BACKGROUND IN THE VIDEO IS NOT THAT COLOR\n" " if (color.y > 0.5)\n" " discard;\n" " gl_FragColor = color; \n" "}\n"; program->addShader(new osg::Shader(osg::Shader::VERTEX, vertexShaderSource)); program->addShader(new osg::Shader(osg::Shader::FRAGMENT, fragmentShaderSource)); here geometry is osg::Geometry pointer to which relative to the vedio Thank you!
