I guessed it was better to open an independent discussion instead of hijacking the thread. 2013/3/19 Douglas Cox &lt;ziflin&lt; at &gt;gmail.com&gt; I'd be interested in knowing more about doing the other thing around. I have a small little language I've been using for a while and I've been fairly happy with it. So far, the language itself does not have reflective constructs (nor I plan to add them) but I use reflection internally mainly to simulate duck typing. So far, I haven't well understood the benefits of reflection. I had seen some examples in ObjC but they didn't really appeared to be buying much from me. I know reflection is there in a Java package, but I couldn't quite figure out the whole picture. Could you please elaborate on the benefits of using reflection? Please be specific on whatever you're talking about reflection from the native core or reflection from the language. Thank you Massimo _______________________________________________</pre> Massimo Del Zotto 2013-03-19T17:35:06 http://comments.gmane.org/gmane.games.devel.sweng/11062 <pre>Hello gents, I wanted to experiment with reflection and I found different way to obtain it: 1) Invasive macro based registration 2) Reflection visitor pattern 3) Parsing pdb/clang stuff and create a manual table of what you want/need 4) c++ custom parser that uses tags to create reflection informations (like a comment near a member, ...) (exuberant ctags???) 5) create serializable/reflected classes in a data format, then run a tool that generates headers and cpps I am trying to figure out flaws and merits of each kind, and even if there are other solutions. I love the idea to have the possibility to serialize in and out structures, access fields and change values, stream in/out stuff from network ,and maybe link with scripting. My goal is to have fast iteration times, both artists and programmers, and I achieved it for rendering programmers already with having json binarized configurable rendering, but still there are code stuff that are not easy to achieve. Here are my thoughts, but I would</pre> Gabriel Sassone 2013-03-14T18:09:30 http://comments.gmane.org/gmane.games.devel.sweng/11061 <pre>http://www.physioth.com/ivjhhzl/bbnxdajysuxrt/kyo_______________________________________________ Sweng-Gamedev mailing list Sweng-Gamedev&lt; at &gt;lists.midnightryder.com http://lists.midnightryder.com/listinfo.cgi/sweng-gamedev-midnightryder.com </pre> Ken K 2013-03-06T01:34:37 http://comments.gmane.org/gmane.games.devel.sweng/11051 <pre>This is a semi on-top and semi-offtopic question. I can't find much information on creating pipelines for creating 3D content for large worlds. I'm finding that artists modelling the "shape" of such words (primitives) of cities, buildings or even natural places such as canyons or valleys is doen pretty quickly, they usually do it in a matter of days. Artists painting texturing and detail to them is also done quickly in nowadays tools, but the absolute bottleneck is UV mapping. The guys modeling take a long time uvmapping everything and artists are often not happy with the resulting UVs. Unwrapping architetural geometry in most 3D apps produces suboptimal results. There is also the problem of texture streaming, for which to achieve a good quality, textures should somehow be split evenly around world areas like quadrants or octants i think. I looked into Carmack's megatexturing approach, but it seems too unnecesarily complex IMO, plus there are no tools available that artists can use commercially? So, I'm loo</pre> Juan Linietsky 2012-11-24T20:50:02 http://comments.gmane.org/gmane.games.devel.sweng/11045 <pre>Hello to all contributors. I need some help in understanding how physics libraries are supposed to be used. I am referring to Bullet in particular as it appears to have everything I need with a liberal, cross-platform licensing. So far I have been experimenting with physics for a few months with mixed results at best. As I write this, I have just resolved an issue with player-controlled objects which has been keeping me awake at night for quite a while so I'm thinking at the next problem I see on the horizon. Now, in Bullet there are three kinds of objects: 1. STAtic 2. DYNamic 3. KINematic I think I have finally got a kinematic behaviour that works right for my game. The point of this email is the interaction of dynamic objects and a world built from static objects. I started modelling my world by procedurally generating a set of hulls, in most cases, those were boxes. I don't remember the exact numbers but I'd say my current data set for the world is about 96% boxes (mostly axis-aligned) and 4%</pre> Massimo Del Zotto 2012-06-11T07:54:32 http://comments.gmane.org/gmane.games.devel.sweng/11016 <pre>Hello ladies and gents, I graduated 5 years ago with the intention of becoming a game developer, my career got sidetracked and although this sidetrack led to an ultimately comfortable existence and a lot of life lessons learned, I'm now at the point where my career as a Flash / Flex developer is stagnating. It may also be coming to a forced end as more and more of my employer's clients move away from Flash each month. I've been keeping up with the times, and doing a lot of graphics programming on the side using nVidia's CG shader programming language and OpenGL. I'm looking for a little insight into what skill level you expect entry level, and reasonably competent graphics programmers (i.e. qualifying as something above 'junior' in their job title, even if that's just the omission of the word) to be at, and the difference between the two. By skill level, I mean knowledge base, for example implementing certain shader routines (e.g. normal mapping) and grasp of mathematics.

When developing games based on large worlds (like Elder Scrolls, GTA, etc), i can imagine that physics and rendering become more jittery the further away the camera moves from the origin (due to floating point precision loss). Is this really a problem? If so, how is this solved? I can imagine that increasing floating point precision to doubles helps a enormously, but i'm not sure if that's enough and if it's worth the extra processing/bandwidth cost. Transforming the world to local coordinates (so the camera is always at the origin) also seems to me like a solution, but sounds like a lot more work and messy code. So, how is this solved in most cases? cheers!

I am using AABB trees for all sorts of stuff in a scene graph. The problem is that we need to quickly calculate a new AABB when an object moves. Therefore I am working on an algorithm for generating vastly simplified convex meshes for fast(ish) AABB calculation for objects that can have an arbitrary orientation. The basic idea is to sort of fit a geodesic sphere over an object to produce a low-poly convex blob that contains the significant maximum extent information from any arbitrary orientation. The geodesic sphere is just a tool for discovering the maximum extent within a solid angle that radiates outward from an origin from within a mesh model. A geodesic sphere has the property that it is constructed from tetrahedrons. Therefore discovery of the maximum extent within each solid angle can occur with a barycentric coordinate evaluation. I am abusing the term solid angle here to mean the volume within a sphere which is a tetrahedron that has one vertex on the sphere</pre> BRIAN LIVINGSTON 2011-06-07T00:52:29 http://comments.gmane.org/gmane.games.devel.sweng/10986 <pre>I'm not sure if this is a common quesiton in the list, but I think tool programming is a very overlooked issue of software engineering in game development. So my question is, since many here have tremendous experience in the game industry and worked on huge projects, what kind of tools do software engineers supply to game or level designers so they can, for example, prototype a game stage before, say, 3D artists start working on a final version? In more depth, games like Halo, God of War or Mario Galaxy for example have really complex scenarios, so complex that a height map or grid map editors do not suffice for prototyping. I can imagine that before 3D artists can start working on the final art, a simpler looking prototype must be created. I also can imagine that creating such prototypes need constant adjusting on the fly (a cliff may be too high, a room to small to fit the enemies, a target out of shooting range), so either special tools for editing stages are created or special plugins for integrating wi</pre> Juan Linietsky 2011-04-20T05:26:25 http://comments.gmane.org/gmane.games.devel.sweng/10964 <pre>Hi folks, I've been working as an AS3 programmer / animator for the last 3.5 years, and have the strongest desire to leave the marketing industry behind and pursue my original intended career as a games programmer, which I sidelined due to a very coincidental series of events. To this end, I've been (slowly) building a graphics engine using C++, OpenGL and nVidia CG which renders very large chunks of terrain using GPU Clipmaps. The idea is that eventually it will render planets with atmosphere and real time shadows, or die trying, and in any case will serve as my main portfolio piece when I eventually start applying for positions. Because I've been outside of my programming comfort zone for so long it's been slow going, but now that I've finally got a firm grasp on shaders and the OpenGL pipeline it's time to look to the future. This is where my problem lies; although there are many examples on the 'net showing me how to animate the most beautiful normal mapped cobbled cube, or tutorials on specific render</pre> Tommy Brett 2011-03-18T12:52:32 http://comments.gmane.org/gmane.games.devel.sweng/10961 <pre>Hi everybody, just curious about the possibility to render the grass shadow in realtime on consoles.
