C++ (Cpp) Matrixd::invert Examples

Example #1

File: CameraController.cpp Project: ymy88/PSDF

Vec3d CameraController::switchCoordinateSystem_point( const Vec3d& point, const Matrixd& from, const Matrixd& to )
{
	Matrixd mat;
	mat.invert(to);

	Vec3d v = point * from * mat;

	return v;
}

Example #2

File: CameraController.cpp Project: ymy88/PSDF

Vec3d CameraController::switchCoordinateSystem_vector( const Vec3d& vec, const Matrixd& from, const Matrixd& to )
{
	Matrixd mat;
	mat.invert(to);

	Vec3d begin = Vec3d(0, 0, 0);
	Vec3d end = vec;

	Vec3d begin2 = begin * from * mat;
	Vec3d end2 = end * from * mat;

	Vec3d v = end2 - begin2;
	return v;
}

Example #3

File: Camera.cpp Project: aitormoreno/OpenSceneGraph

Matrixd Camera::getInverseViewMatrix() const
{
    Matrixd inverse;
    inverse.invert(_viewMatrix);
    return inverse;
}
