New methods osg::Geometry::containsDeprecatedData() and osg::Geometry::fixDeprecatedData() provide a means for converting geometries that still use the array indices and BIND_PER_PRIMITIVE across to complient
versions.
Cleaned up the rest of the OSG where use of array indices and BIND_PER_PRIMITIVE were accessed or used.
GeometryNew is only temporary and will be renamed to Geometry on the completion of refactoring work and feedback from community.
Ported osggeometry across to use GeometryNew.
The following change to State.cpp fixes the case where textures in a stateset along with a compute shader program did not make those textures available to the shader, since it got evaluated before the texture bind(s)."
Note from Robert, Michael only change State::apply(StateSet*) so I also applied the same reversal in apply of texutre modes/state into the State::apply() method for consistency.
I looked into the "State::applyShaderComposition" method and noticed that it will print debug information to the osg::INFO stream. I commented that line out and the performance drop was gone.
I'm not sure if the printing was accidentally left in or is meant to be enabled. I've modified the function to only call the print function if INFO logging is enabled. I've attached the change."
Failure to perform a vertical flip on S3TC-DXTC now simply leaves the original image instead of corrupting it.
Image.cpp was sometimes performing a "normal" (= for uncompressed images) vertical flip on S3TC-DXTC images, producing weird results.
Actually, code was trying a "DXTC vertical flip" and relied on the result to call a "normal vertical flip". But when the "DXTC v-flip" encounters an error, this is is not necessarily because the image is not S3TC (ex: unhandled image dimensions)!
So now the code simply does "if dxtc, then flip_dxtc; else flip_normal;".
Note from Robert Osfield, moved the isDXT function into the dxt_tool file and namespace.
TextureBuffer objects may use osg::Texture::bindToImageUnit(), so GLSL shaders are able to use not only texelFetch() function , but also functions defined in GL_ARB_shader_image_load_store extension : imageLoad(), imageStore(), imageAtomicAdd() etc."
second email: "After a while I found that osg::Texture::applyTexParameters() used with TextureBuffer may cause some OpenGL errors ( applying texture filters and wraps to TextureBuffer makes no sense ) so I fixed it."
I hope the change seems reasonable. I searched the entire code base for code that accesses the StateSetStack, and noticed RenderBin and RenderStage use it. However, I don't think that code would ever be called from within the State::apply() function, so I'm fairly confident the change should be safe."
OSG_DEBUG << "Hello world!\n";
the underlying stream is not automatically flushed. It is flushed
if endl is queued instead of \n:
OSG_DEBUG << "Hello world!" << std::endl;
The notify macros do:
stream->setCurrentSeverity(severity);
return *stream;
So, if a function do:
OSG_DEBUG << "This is a debug message\n";
OSG_NOTICE << "This is a notice message" << std::endl;
the debug message will be classified as a notice message.
It is a problem when the application uses a NotifyHandler. The notify
method of the handler is called with:
severity = NOTICE
message = "This is a debug message\nThis is a notice message"
The attached Notify.cpp contains an automatic flush of the stream when
the current severity changes.
"
If the index is more than the size of _children vector, the new child is pushed at the end of the vector, but the index value is unmodified, so an incorrect value is passed to the "childInserted" method."
* avfoundation: added support for IOS (CoreVideo-support is still in development, works only for SDK >= 6.0, set IPHONE_SDKVER in cMake accordingly)
* zeroconf: added ZeroConf-device-plugin (Mac/Win only, linux implementation missing) to advertise and discover services via ZeroConf/Bonjour, on windows you'll need the Bonjour SDK from Apple
* osgosc: modified the example to demonstrate the usage of the ZeroConf-plugin (start the example with the command-line-argument --zeroconf)
* SlideShowConstructor: enable/disable CoreVideo via a environment variable (P3D_ENABLE_CORE_VIDEO)
* RestHttp: mouse-motion-events get interpolated
* RestHttp: unhandled http-requests get sent as an user-event to the event-queue, all arguments get attached as user-values to the event
* modified some CMakeModules to work correctly when compiling for IOS
* fixed a compile-error for IOS in GraphicsWindowIOS
* some minor bugfixes"
