/** |
||||||
|
* This test demonstrates various GImpactCollisionShapes colliding against two identical curved surfaces. The |
||||||
|
* left surface is a MeshCollisionShape, right surface is another GImpactCollisionShape. An ideal result is |
||||||
|
* for all objects to land and change to a blue colored mesh indicating they are inactive. Falling through the |
||||||
|
* floor, or never going inactive (bouncing forever) are failure conditions. |
||||||
|
* <p> |
||||||
|
* Observations as of June 2019 (JME v3.3.0-alpha2): |
||||||
|
* <ol> |
||||||
|
* <li> |
||||||
|
* With default starting parameters, Native Bullet should pass the test parameters above. JBullet fails due to |
||||||
|
* the rocket/MeshCollisionShape never going inactive. |
||||||
|
* </li> |
||||||
|
* <li> |
||||||
|
* Native Bullet behaves better than JBullet. JBullet sometimes allows objects to "gain too much energy" after |
||||||
|
* a collision, such as the rocket or teapot. Native also does this, to a lesser degree. This generally |
||||||
|
* appears to happen at larger object scales. |
||||||
|
* </li> |
||||||
|
* <li> |
||||||
|
* JBullet allows some objects to get "stuck" inside the floor, which usually results in a fall-through |
||||||
|
* eventually, generally a larger scales for this test. |
||||||
|
* </li> |
||||||
|
* <li> |
||||||
|
* Some shapes such as PQTorus & signpost never go inactive at larger scales for both Native and JBullet (test |
||||||
|
* at 1.5 and 1.9 scale) |
||||||
|
* </li> |
||||||
|
* </ol> |
