[osg-users] [osgPPU] why would The Hdr Effects disappeared from hdrExample after scene adding to the ive format model?
Hi, What are the requirements for this model format for this effect or can't be displayed because the parameter settings are incorrect? Thank you!

Re: [osg-users] I don't quite understand this part of code from hdr examle, can anyone elaborate more?

[osg-users] why the "adaptedlum->addChild(brightpass)" code is doing what it does In the osgPPU hdr example
Hi,
// The adapted luminance ppu do compute it. However if you
// can follow me for now, you maybe encounter, that this ppu do
// have to write into the same texture as it also read from.
// To prevent this, we just generate an inout ppu which do
// nothing than render the copy of input to the output.
// We will use the output of this ppu as input for the
// adapted luminance ppu. In this way we do not write to the
// same texture as we have readed from.
osgPPU::UnitInOut* adaptedlumCopy = new osgPPU::UnitInOut();
adaptedlumCopy->setName("AdaptedLuminanceCopy");
adaptedlumCopy->addChild(adaptedlum);
// now connect the output of the adaptedlum with the rest where it
is needed
adaptedlum->addChild(adaptedlumCopy);
adaptedlum->addChild(brightpass);
brightpass->setInputToUniform(adaptedlum, "texAdaptedLuminance");
adaptedlum->addChild(hdr);
hdr->setInputToUniform(adaptedlum, "texAdaptedLuminance");
Thank you!
Cheers,
Mirro

[osg-users] why does the adding of lighting, colour and fusion to the "shader" model result in the opacity of its windowpane?
Hi,
Code:
const char* gl2_VertexFaceShader = {
"vec4 directionalLight(in vec3 normal,in vec4 color)\n"
"{\n"
" float NdotL = dot(normal,
normalize(gl_LightSource[0].position.xyz)); \n"
" NdotL = max(0.0, NdotL); \n"
" float NdotHV = dot(normal, gl_LightSource[0].halfVector.xyz);
\n"
" NdotHV = max(0.0, NdotHV); \n"
" color *= gl_FrontLightModelProduct.sceneColor + \n"
" gl_FrontLightProduct[0].ambient + \n"
" gl_FrontLightProduct[0].diffuse * NdotL; \n"
" if (NdotL * NdotHV > 0.0)\n"
" color += gl_FrontLightProduct[0].specular * pow(NdotHV,
gl_FrontMaterial.shininess); \n"
" return color;\n"
"}\n"
"varying vec2 texCoord;\n"
"varying vec4 vertexColor;\n"
"void main(void)\n"
"{\n"
"gl_Position = gl_ModelViewProjectionMatrix * gl_Vertex;\n"
"texCoord= gl_MultiTexCoord0.xy;\n"
"vec3 normal = normalize(gl_NormalMatrix * gl_Normal);\n"
"vertexColor = directionalLight(normal,gl_Color); \n"
"}\n"
};
const char* gl2_FragmentFaceShader = {
"uniform vec3 highlightColor;\n"
"uniform float transparency ;\n"
"uniform sampler2D baseTexture;\n"
"varying vec2 texCoord;\n"
"varying vec4 vertexColor;\n"
"void main(void)\n"
"{\n"
"gl_FragColor = vertexColor * texture2D(baseTexture, texCoord) *
vec4(highlightColor.x,highlightColor.y,highlightColor.z,transparency);\n"
"}\n"
};
Thank you!
