Soruces for simple OpenGL 2.0 HUD/GUI for android

 Posted on July 18, 2014  |  Sascha

As I’m currently prototyping a new game for Android, I was in need of a quick (and simple) way of adding some selectable text elements on top of my 3D OpenGL ES scene. So I created a simple demonstration with full source (you can get them from my OpenGL ES git repository) that renders a 3D scene and a basic hud with clickable text elements on top of it in orthogonal mode.

Android OpenGL ES repository

 Posted on July 12, 2014  |  Sascha

Following the C++ (OpenGL) repository, I recently added an Android OpenGL ES repositry (using Java) over here. It currently only contains two public demos, one for a simple stl viewer and another one for using the camera input of an android device as an OpenGL ES texture, but over time I plan on adding more and more demos. And though I used to mock Java in the past I really like coding with Java nowadays. [Read More]

OpenGL ES CapsViewer updated to 0.3

 Posted on February 21, 2014  |  Sascha

High on the heels of the last release (0.2), I just updated the OpenGL ES CapsViewer to version 0.3. Changelog : Changed way of setting up the OpenGL ES render context Certain devices (mostly those with PowerVR GPUs) were reporting wrong OpenGL ES versions (e.g. 1.1 instead of 2.0). I’ve changed the way of setting up the highest possible OpenGL ES version, so those devices should now display their real supported OpenGL ES version. [Read More]

OpenGL ES CapsViewer update to 0.2

 Posted on February 18, 2014  |  Sascha

I’ve just released an update for the OpenGL ES CapsViewer to google’s playstore. This version should fix crashes upon startup that seemed to be caused by a wrong egl configuration, so for this version I’ve changed the method of selecting the egl configuration for the render context. So if the application crashed on your device feel free to update (in case you’ve turned automatic updates off) the the most recent version and submit your OpenGL ES reports. [Read More]

OpenGL ES Caps Viewer available on Playstore

 Posted on February 3, 2014  |  Sascha

My first ever mobile app is now available over at Google’s PlayStore! This is a premiere for me, and though I wasn’t on wether to spend the 25$ registration fee for the google’s developer console, I hope many android apps and games will follow. Download via Google play The OpenGL ES CapsViewer is the mobile counterpart to the OpenGL CapsViewer, reading the OpenGL ES implementation info of your Android device, as well as device information that may be of use to developers.

3D loader for android, first roaming zombies

 Posted on January 30, 2014  |  Sascha

A 3d game needs 3d models, so I wrote a simple .obj (wavefront) model loader, and it was surprisingly easy with java. It took me roughly 30 minutes and is no more than 50 lines of code (including declarations and comments). So the “game” (still no gameplay in) can now display 3d models, and since it’s a zombie game, I’ve put in a (drum roll please) zombie! But it’s not just visual, but also backed by an NPC class that makes it move (more or less randomly) around the dungeon in a turn based manner. [Read More]

Zombie infected random dungeon crawling

 Posted on January 20, 2014  |  Sascha

2014 started off pretty busy and I haven’t had that much time to work on my current (and first) android project. But at least I wrote down the first pages of the basic game design draft, and I plan on doing a randomly generated, zombie themed dungeon crawler with not your usual zombie story. So in terms of gameplay it’ll be a traditional dungeon crawler (think of Eye of the Beholder, or more recently Legend of Grimrock), with semi-realtime movement but with a modern horror theme based on a zombie infection (yeah, I know, zombies are all around nowadays, see the success of DayZ, but I always wanted to do something with zombies anyway).

2013 - Final posting - Dwelling in randomly generated mobile Dungeons

 Posted on December 29, 2013  |  Sascha

Another year has (almost) passed, and as with the previous years I’ll keep up the tradition of publishing a final posting before heading into 2014. From a personal point-of-view, 2013 wasn’t thad bad (though still far from perfect) like some of the years before. I still earn my money as a sofware developer using delphi and love my job, and recently I even bought the house I’ve been spending most of my 32 years in (though there is still a bit of renovation to be done, but the house itself is in a good shape).

OpenGL ES Hardware Database Preview

 Posted on December 18, 2013  |  Sascha

It took (a bit) longer than expected, but I finally got the first preview of the online OpenGL ES Hardware Database online. I want this to be the match to the widely used OpenGL Hardware Database (filled by the glCapsViewer). Where the former is aimed at developing desktop applications with OpenGL, the later one is planned to be a helper for all developers planning on deploying OpenGL ES based applications, games or tools on the Android platform (other platforms that support OpenGL ES may follow in the future, the database design is flexible enough) that want to know what features are offered by the different devices on the market.

From Delphi, Windows, OpenGL and Newton to

 Posted on November 8, 2013  |  Sascha

…Java , Android, OpenGL ES and Box2D. That’s what I’ve been doing the last few days during my (currently rather rare) coding sessions. I wrote a simple physics playground using JBox2D for my phone that allows me to drop different objects by the touch of a finger and also uses the orientation sensor to change the gravity vectors. Putting lots of dynamic objects inside a confined box, and seeing them fall over by just tilting the phone is a fun affair ;) [Read More]
