Hi,
maybe check code in osgfpdepth example.

Hi,
I've done all the tests, and they are all ok.
May the problem comes from the depth buffer attachment ?
When I use :
Code:
p_camera->attach(osg::Camera::COLOR_BUFFER, p_renderTextureColor, 0, 0, false,
4, 4);
p_camera->attach(osg::Camera::DEPTH_BUFFER, p_renderTextureDepth, 0, 0, false,
4, 4);
or :
p_camera->attach(osg::Camera::COLOR_BUFFER, p_renderTextureColor, 0, 0, false,
4, 4);
p_camera->attach(osg::Camera::DEPTH_BUFFER, p_renderTextureDepth);
There is black screen, but if I don't attach depth buffer, I got something rendered and
no "Warning: detected OpenGL error 'invalid operation' at after
RenderBin::draw(..)" errors in the console.
Here is how I create my textures :
Code:
// Main color texture
p_renderTextureColor = new osg::Texture2D();
p_renderTextureColor->setTextureSize(p_osgViewport->width(),
p_osgViewport->height());
p_renderTextureColor->setInternalFormat(GL_RGBA32F_ARB);
p_renderTextureColor->setSourceFormat(GL_RGBA);
p_renderTextureColor->setSourceType(GL_FLOAT);
p_renderTextureColor->setFilter(osg::Texture2D::MIN_FILTER,
osg::Texture2D::LINEAR);
p_renderTextureColor->setFilter(osg::Texture2D::MAG_FILTER,
osg::Texture2D::LINEAR);
p_renderTextureColor->setWrap(osg::Texture::WRAP_S,
osg::Texture::CLAMP_TO_EDGE);
p_renderTextureColor->setWrap(osg::Texture::WRAP_T,
osg::Texture::CLAMP_TO_EDGE);
p_renderTextureColor->setDataVariance(osg::Object::DYNAMIC);
p_renderTextureColor->setUseHardwareMipMapGeneration(false);
p_renderTextureColor->setResizeNonPowerOfTwoHint(false);
// Main depth texture
p_renderTextureDepth = new osg::Texture2D();
p_renderTextureDepth->setTextureSize(p_osgViewport->width(),
p_osgViewport->height());
p_renderTextureDepth->setSourceFormat(GL_DEPTH_COMPONENT);
p_renderTextureDepth->setSourceType(GL_FLOAT);
p_renderTextureDepth->setInternalFormat(GL_DEPTH_COMPONENT32F);
p_renderTextureDepth->setFilter(osg::Texture2D::MIN_FILTER,
osg::Texture2D::LINEAR);
p_renderTextureDepth->setFilter(osg::Texture2D::MAG_FILTER,
osg::Texture2D::LINEAR);
p_renderTextureDepth->setWrap(osg::Texture::WRAP_S,
osg::Texture::CLAMP_TO_EDGE);
p_renderTextureDepth->setWrap(osg::Texture::WRAP_T,
osg::Texture::CLAMP_TO_EDGE);
p_renderTextureDepth->setDataVariance(osg::Object::DYNAMIC);
p_renderTextureDepth->setUseHardwareMipMapGeneration(false);
p_renderTextureDepth->setResizeNonPowerOfTwoHint(false);
Thank you!
Cheers,
