3d: Free memorization: To display a Box: we use Triangles:

Frame:
int initialize_box () {
	vTriangle* tri = new vTriangle();
	tri->setTriangle ( new vPoint(0.0f, 0.0f, 0.0f), new vPoint( 50.0f, 0.0f, 0.0f), new vPoint( 0.0f, 50.0f, 0.0f) );
	//tri->setPoint ( new vPoint(0.0f, 50.0f, 0.0f), new vPoint( 00.0f, 5 0.0f, 0.0f), new vPoint( 0.0f, 0.0f, 0.0f) );
}

int initialize_box () {

	vPoint* p1 = memorizevPoint(0.0f, 0.0f, 0.0f);

// 20200307
static LRESULT CALLBACK mainWindowProc( HWND hWnd, UINT uMsg, WPARAM wParam, LPARAM lParam );

Parameters come from the above function:
And we could move the below functions except wButtonController and wCanvasController: 

int initialize_box () ;
int display_box ( HWND hWnd, HDC hDC, PAINTSTRUCT* ps, UINT uMsg, WPARAM wParam, LPARAM lParam ) ;

By use of Frame works, we create, we can solve the above.
At the most, we are going ton change Procee in wButtonController and wCanvasController, we must realise there isn't any other ways.
