A com.jme3.bounding.BoundingVolume is an interface for dealing with containment of a collection of points. All BoundingVolumes are <code>Collidable</code> and are used as optimization to calculate non-physical collisions more quickly: It's always faster to calculate an intersection between simple shapes like spheres and boxes than between complex shapes like models.

One of the supported <code>Collidable</code>s are meshes and scene graph objects. To execute a collision detection query against a scene graph, use <code>Spatial.collideWith()</code>.

<h3><a>What is java.lang.LinkageError: Version mismatch?</a></h3>
<div>
<p>
This rare exception shows a message similar to the following: <code>Exception in thread "LWJGL Renderer Thread" java.lang.LinkageError: Version mismatch: jar version is (number), native library version is (another number)</code>. jME3 needs native libraries (.dll, .jnilib, lib*.so files) to run LWJGL and jBullet. The correct versions of these libraries are included when you install the <acronymtitle="Software Development Kit">SDK</acronym> or download the binaries. However there are circumstances where jME3 cannot determine which copy of the native library it should use: <br/>
If you install another application that needs a different version of a native library, and this app globally installs its version over jME3's; or if an old copy of a native library is in your project directory, your home directory, or Java library path, or in the classpath; or if you permanently linked an old copy in your IDE's settings; then Java assumes you prefer these native libraries over the bundled ones, and your jME3 application ends up running with the wrong version. <br/>
To fix this, search for .dll (Windows), .jnilib (Mac), and .so (Linux) files for jBullet and LWJGL on your harddrive and in your path and IDE settings, and verify they don't interfere. (If you have other jME versions installed and linked somehow, the outdated natives may also be in a lwjgl.jar or jbullet.jar file!)

<p><div>Storing the textures inside your project directory is necessary for the paths in JME's binary model files (.j3o) to work. Treat the paths of your assets like class names of java classes, they define a specific asset. When you later generate .j3o files, compile class files, and distribute the project, paths and files need to be available in their final absolute form. It is imperative to keep the same directory structure from beginning to end. <br/>
If you ever change the assets directory structure, you will have to do manual refactoring (just as for Java package name changes): You will need to re-export all affected models, regenerate all affected .j3o files, and manually update all affected paths in your code.

It's a fact of life, math is hard. Unfortunately, 3D graphics require a fair bit of knowledge about the subject. Fortunately, jME is able to hide the majority of the details away from the user. Vectors are the fundamental type in the 3D environment, and it is used extensively. Matrices are also a basic necessity of 3D for representing linear systems. Quaternions are perhaps the most complicated of the basic types and are used for rotation in jME.
