oliver s blog oliver s blog this machine will will not communicate these thoughts and the strain i am under saturday september 22 2012 dante and waffle chad versace s xdc2012 waffle presentation included a demo of dante running with a waffle backend with dynamic switching of the window system x11 glx or wayland using an environment variable i definitely intend to research and hopefully even contribute to waffle in the future chad quickly wrote 95 or more of the waffle backend i provided some guidance and a small patch to stubbed out x11 input together we managed to pull this together

developers conference xdc2012 friday august 17 2012 prebuilt android apks i have quickly uploaded a dante debug apk and some basic info to http dante mobi debug in the apk context means the code is not signed with a key so you need to enable installation of such packages in the android settings menu the code is compiled with optimizations but do not expect anything above single digit frames per second presently optimization is something i m working towards but the fact remains that many of the current generation devices simply do not have the gpu horsepower to run the game at an acceptable greater than or equal to 30 fps rate memory is another major killer you need as much as possible available currently the dante icon will launch the doom 3 game to the main menu however at least on my device it s not possible to launch the single player campaign aka game mars_city1 due to memory requirements again this is something that will be improved in the future you need to make the directory and copy your doom 3 pk4 files into sdcard android data com game dante base from your cds or dvd you must also copy pak000_gl2progs pk4 into the same directory otherwise the game will not run this file contains the glsl shaders required by dante the apk package is not guaranteed to run on your specific device you re welcome to file a issue about it on github but please check for duplicates first it s also not my fault if the apk destroys your device kills your kitten or causes the mayan apocalypse i ll write up some detailed instructions for compiling and installing dante on android later this week or early next week for those who wish to do this or don t trust installing my apk package happy hacking posted by oliver mcfadden at 08 18 17 comments labels dante development doom 3 egl es2 gles2 glsl opengl sunday august 12 2012 dante with android with much thanks to krzysztof kkszysiu klinikowski we now have mostly working support for android devices in dante that is to say the code is there the build scripts are there but it s still not an easy process for the user to build their own dante apk package for their phone tablet i am considering writing a detailed how to guide on setting up the android sdk and ndk creating the standalone toolchain and running the build it s not really difficult it s just tedious to execute all of the commands required for the android build i have shell scripts which do most but not all of the work checked into git however you still need to know how to use them how to modify them to point to your ndk and standalone toolchain and finally how to transfer the doom 3 media assets onto your device right now the process is definitely not very easy nor streamlined we are not yet at a point where this is user friendly you re welcome to visit us in the dante irc channel on irc freenode net if you really want to build your own packages get involved in the development or just see what s happening in real time okay this is a free time project so you may have to idle a bit and the channel is not always active performance is currently bad i am aware of this and it s something we re working on improving in various ways it s unlikely to happen overnight touchscreen input is also bad but i expect this will improve fairly quickly adding good on screen controls to be able to move and look around i see as a much more difficult problem perhaps one that will be solved with a wearable device such as a phone or mini tablet a bluetooth wireless controller and the oculus rift i ll have to wait for my unassembled prototype in november to find out audio support currently does not exist though progress is being made in this area you can see the bugs and planned enhancements features on dante s github issue tracker happy hacking posted by oliver

aka idtech4 es2 0 aka oliver s doom aka omcfadde s doom to an easier to remember name going forward the repository will be named dante based on dante s inferno and it s fitting description of the doom 3 game dante journeyed through hell guided by the roman poet virgil hopefully this will make it much easier to uniquely and easily identify my repository unfortunately for those of you who already have clones of the idtech4 repository from github you will need to adjust the remote origin to point to the new address i apologize for any inconvenience don t worry the project is continuing as usual the only change is the repository name posted by oliver mcfadden at 23 42 9 comments labels dante doom 3 egl es2 git gles2 glsl opengl wednesday august 1 2012 doom 3 blinn phong vs phong without going into the technical and implementation details of each shading algorithms i would like to request comments from people as to which you prefer visually unmodified doom 3 uses the blinn phong shading model which is an approximation of the more computationally expensive phong shading model both images are using a fixed exponent of 16 0f however it s possible to adjust the exponent based on material type in both shading models currently this is not done a higher exponent produces a tight specular highlight for example chrome metal while a lower exponent will produce a broader highlight for example matte paint or skin tones please note that some tuning of the exponent may be required for the phong model due differences in lighting calculation doom 3 blinn phong 16 0f doom 3 phong 16 0f
