Our next step is to put everything together to build a basic 3D game with Shapes, including basic gameplay mechanics and basic UI. You will then go through LibGDXвЂ™s 3D rendering API main features and talk about the camera used for 3D. You will start off with the basic Intellij environment, workflow and set up a LibGDX project with necessary APIs for 3D development. This book will teach readers how the LibGDX framework uses its 3D rendering API with the OpenGL wrapper, in combination with Bullet Physics, 3D Particles, and Shaders to develop and deploy a game application to different platforms This should give you a file called ship.LibGDX is a hugely popular open source, cross-platform, Java-based game development framework built for the demands of cross-platform game development. DonвЂ™t drag and drop your fbx file on fbx-conv, it will not work for most scenarioвЂ™s.

#LIBGDX 3D BLENDER MODELS HOW TO#

I assume you know how to execute command line (CLI) utilities on your platform. fbx-conv-win32, in which case you should use that name accordingly. Note that the actual executable might be named differently, e.g.

Make sure the other files (like ship.mtl) are within the same folder. There are two file formats LibGDX support, g3dj (which is json textual for easy debugging) and g3db (binary which you should use on release, because itвЂ™s smaller and faster to load). Unlike the name might suggest, fbx-conv is suitable for converting many file formats (including obj), although fbx is the preferred file format because almost every modeling application support that format.

Luckily thereвЂ™s fbx-conv, which converts models exported from modeling software to a format suitable for rendering using LibGDX. In fact, the ObjLoader that is included with LibGDX is only intended for testing and doesnвЂ™t implement all functionality you might want to use. But it is not suitable to use in a real application, because the file format doesnвЂ™t include enough information for rendering complex models. Using an obj (wavefront) file is nice for testing.

In the doneLoading method we now create multiple instances and position them in a grid on the XZ plane. Note that you can also scroll the mouse to zoom in or out. Here we move the camera a bit away from the origin, so we can see all our ships. Public class LoadModelsTest implements ApplicationListener Now letвЂ™s change the Basic3DTest to use that model instead of the box we created earlier: ThatвЂ™s to be expected and will be resolved later on. If you use your own (OBJ) model, you might notice that it might not render correctly. Later on in this tutorial we will see how to convert a model to a more suitable file format. The OBJ format is not fully supported and should be avoided. This is only done for the sake of this tutorial. Please note that this model is in the wavefront (OBJ) file format.

ship.png: the texture the material uses.

ship.mtl: the wavefront material file the model uses.

ship.obj: the wavefront model file we're going to load.

Notice that it contains three files, which must be included in the same folder:

#LIBGDX 3D BLENDER MODELS ANDROID#

You can extract it to the data folder within the assets folder of the android project. I used the ship model that comes with LibGDX gdx-invaders, you can find it here.

You can start your favorite modeling application or grab an existing model.

The full source, assets and a runnable tests of this tutorial can be found on this github repository. Now letвЂ™s make things a bit more iteresting by adding loading a model instead of creating a box. WeвЂ™ve setup a camera, added some lights and rendered a green box. In the previous tutorial, weвЂ™ve seen how to setup libgdx for rendering a 3D scene.
