I want to change the output of my SWIG of the class btVector3 to a struct btVector3. The main issue I'm having is that I'm using BulletPhysics and I need a few core components to use structs as normal to prevent cache trashing.
"btVector3 can be used to represent 3D points and vectors. It has an un-used w component to suit 16-byte alignment when btVector3 is stored in containers."
************************** C++ aligned class ************************
__declspec(align(16)) class btVector3
{
public:
union {
__m128 mVec128;
btScalar m_floats[4];
};
//...
}
************************** c# Wrapper OUTPUT ************************
public class btVector3 : IDisposable {
private HandleRef swigCPtr;
protected bool swigCMemOwn;
internal btVector3(IntPtr cPtr, bool cMemoryOwn) {
swigCMemOwn = cMemoryOwn;
swigCPtr = new HandleRef(this, cPtr);
}
internal static HandleRef getCPtr(btVector3 obj) {
return (obj == null) ? new HandleRef(null, IntPtr.Zero) : obj.swigCPtr;
}
~btVector3() {
Dispose();
}
public virtual void Dispose() {
lock(this) {
if (swigCPtr.Handle != IntPtr.Zero) {
if (swigCMemOwn) {
swigCMemOwn = false;
BulletPhysicsPINVOKE.delete_btVector3(swigCPtr);
}
swigCPtr = new HandleRef(null, IntPtr.Zero);
}
GC.SuppressFinalize(this);
}
}
///...
}
************************** C# Wrapper GOAL (TARGET) ************************
[StructLayoutAttribute(LayoutKind.Sequential, CharSet = CharSet.Ansi)]
public struct btVector3 {
[MarshalAs(UnmanagedType.ByValArray, SizeConst = 4)]
public float[] m_floats;
}
}
