java - How can I convert an ArrayList<Vector3f> to a ByteBuffer? -

i'm trying create triangleindexvertexarray jbullet, need parse bytebuffer of vertices in model.

i have got arraylist<vector3f> of vertices in model.

how can parse list of vector3f's bytebuffer?

you can follow

declaring vertices

arraylist<vector3f> verticesnew = new arraylist<vector3f>(); 

set vertices

vertices.add( new vector3f(somevertice) ); 

get float buffer vertices:

// there 3 floats needed each vertex (x,y,z) int buffersize = vertices.size() * 3 * float.size; floatbuffer verticesbuffer = bytebuffer.allocatedirect( buffersize ).order( byteorder.nativeorder() ).asfloatbuffer();  // copy values list direct float buffer ( vector3f v : vertices )     verticesbuffer.put( v.x ).put( v.y ).put( v.z );
