Here is the second tech demo by maister made to showcase what is possible with libretro GL. SceneWalker is a heavily modified version of ModelViewer.
Instead of loading ‘character models’, its main purpose is to load in ‘scene models’. Once loaded in, you can then walk around these environments from a first-person perspective. It’s possible to move through environments using either the D-pad and/or the analog sticks. Pressing RetroPad B button allows you to jump – this comes in handy with some models where certain obstacles are preventing you from fully traversing the environment.
A great deal of environments already work within this SceneWalker app – the initial ‘placement’ of your starting position is currently a problem in some models since it is possible for you to be ‘dropped’ inside a void space. This happens for instance with the ‘Devil May Cry 4’ street model which makes it impossible to walk around that map.
Other maps (such as Silent Hill 3’s chapel) work fine on the other hand.
Basic collision detection and gravity has been implemented – it mostly works the part for most models.
Below you’ll find some screenshots of some models that we have loaded into this SceneWalker.
Scene Walker right now runs on:
- PC (Windows/UNIX/OSX)
- Blackberry QNX (BB10/Playbook)
The maximum supported internal resolution at which you can render the models depends on the platform you’re running Scene Walker on. On the mobile platforms we have consciously decided to set the maximum supported resolution at 1024×768 – this should be the native resolution of the iPad 2/iPad Mini and it is doubtful that even on a powerful tablet you’d have much need for 1080p internal resolution anyway.
On PC 1920×1600 is the maximum internal resolution at which you can render these models.
Like all the non-GL based libretro cores, you can apply any amount of shaders that you want.

I’m not exactly sure how hard-ball game developers are when it comes to these models – but anyways, there is a lot of source material you can find on the Internet.
Some places that supply them is DeviantArt (search for DeviantArt + XNALara- that should show up a bunch).
Another site that I’ve found includes a lot of useful models is this one (http://thefree3dmodels.com/). Make sure that when downloading a model form there, that it says ‘OBJ’ or something similar. Models that are not in this format can’t be expected to run right now.
