I barely know C++ and minimizing things isnt easy. For gcc I didn't test it well enough but it is nothing serious ATM, unlike clang's crashing case which was blocking some moves.

Re: [ANN][WIP] Library & app for 3D visualization system
I just try gcc-snapshot from new Ubuntu and I can build Objective-C++ with it now. It failed on some methods that look like message::, ie. having any argument w/o textDescription: But at least it doesn't crash like clang on some cases (sorry but C++ code was killing enough of my not-so-much-left neurals and I decide to avoid that rather to minimize the nested C++ case to make a bug reports) Anyway, I found it's more interesting with the new released Macbuntu as it does docking by default and has horizontal menu on the top screen edge finally. What's the behavior of our GNOME theme when running in this environment? -- ..

Re: [ANN][WIP] Library & app for 3D visualization system
Hi, Some updates on the current details implementations in 3SUM application project. Now it's only about AP3, the AppKit inspired, a forked and rewritten of GNU 3D Kit, 3D engine. latest list of changes * Now depending on clang for Objective-C++, would be nice if someone can help me making it work with GCC, which could be either using GCC's Objective-C++ or writing a C struct front, to allow .m to include .h. Now all files must be mm. * Changing AX prefix to AA, I planned to keep AX for binary stream APIs. Binary stream in AP3 are like an array of float or double, using stride to divide them into blocks. It isn't a priority for AP3 as it's mostly for modeling works which is a part of 3SUM. * The current code based is quite clean and well tested. AAAffineTransform, which is 3D internally, has similar interface to NSAffineTransform and should pass its tests. Some test sets for 3D transformations would be very welcome. What are next? * Getting camera to work in 3D to NSView conversions. * Start working on controllers. Controllers are a collection of NSControl and its 3D counterpart AAControl that can be used to manipulate scene graph data model. I'd start with some NSView based for testing then I will move on the shader part before getting back to make 3D controls. * Shader, like GNUstep's rendering back-ends. The current focus is to use GL view for real time and Aqsis for real rendering. 3D objects are responsible to maintain shading infos for each backend. Shader will have front-end to collect shader languages in sets. eg. a set could contain a delegate to rendering code either for multiple versions of OpenGL code blocks, or NSGraphicsContext or a renderman shader strings, * Raster, will start working on this once we have texture. * Symbol systems, so you can refer to objects by name, or have something like $X in text field to refer to some shared values. * One day I may want to use this 2D display, NSView based code to make a general 2D vector application but with powerful perspective engine and constructional history or helping implementing a CAD application. Just that I really have had some good experiences editing bezier path in Blender.

Cool project. I will try this later.

[ANN][WIP] Library & app for 3D visualization system
Dear GNUstep people, I have been working on these for a while after looking at that SNAP thing I decided to put up this premature announcement. First, I am working on a framework called AP3, which abbreviates nothing but stands for ape coz I love monkey. AP3 is a 3D application development framework which currently included a basic scene graph, a sample OpenGL view to display 3D information currently just some meshes, but all the goals are * Data model, built around COLLADA, has a quite complete and working COLLADA parser which I barely use, however. * Basic object or view, heavily inspired by Blender's internal data structure (unnecessarily), these basic view objects are in so many way like NSView, just in 3D. The model data above can be shared and exchanged and ID'ed between basic view objects (Think of duplicate linked, if you know Blender). They might have a single parent and children objects just like NSView... and any scene graph system. The APIs will also try to imitate NSView's, but with additional Z axis, having 3D ray "hitTest" to map the mouse action, well you get the picture. * Animation system, time-based with graphs, FK/IK * Rendering engine backend(s), quite like GNUstep's rendering backend but more visible and can have more than 1 of them working at the same time. The rendering engine backends can be either used for shading 3D data model which attached shading language (eg. GLSL or Renderman) over an NSOpenGLView or invoking other photo realistic renderer, the first idea is to support Aqsis renderer. The default real time engine should be extensible enough for general purpose rendering but it will not define a strict display API like GNUstep's display backend. * 2D raster engine. This engine is a rewrite of my own maliwan project. It can be used to implement procedural texture generation also a GIMP clone if you want to make one. The data model was built around lcms library which dealt with ICC color profile management. Mainly the old node system will be rewritten since I think I have a better design for that based on DAG'ed invocations (which will also be used in the procedural 3D modeling) This project can be described as a fork of GNUstep 3DKit but didn't share the code (not anymore, I think). Second project, I called this one 3Σ, which will utilize the AP3 framework, is just like GORM but in 3D though has way cooler name. It will include many 3D modeling functionalities as I want to make this one a Houdini killer and ... I can just dream about that for now, the first phase would just be able to use it to layout the scene and linking methods and properties' relationships and generate a GORM file?!?! The website of the project is at http://mus3.sourceforge.net/ which currently has no source code pool (or it did? must be pretty obsolete). I'm managing the code that some part was GPL'ed but the project should be at least LGPL so this will take some time to make a release or put it in public. Beside that, most parts need a clean up and I am migrating clean source (now 2 files) into my local git and will have it on-line ASAP. If anyone is interested and want to join the development you can write me.
