Method getModelViewMatrix

octovis/src/extern/QGLViewer/camera.cpp:651–658

! Fills \p m with the Camera modelView matrix values. First calls computeModelViewMatrix() to define the Camera modelView matrix. Note that this matrix may \e not be the one you would get from a \c glGetDoublev(GL_MODELVIEW_MATRIX, m). It actually represents the state of the \c GL_MODELVIEW after QGLViewer::preDraw(), at the \e beginning of QGLViewer::draw(). It converts from the world to t

void Camera::getModelViewMatrix(GLdouble m[16]) const
{
	// May not be needed, but easier like this.
	// Prevents from retrieving matrix in stereo mode -> overwrites shifted value.
	computeModelViewMatrix();

		m[i] = modelViewMatrix_[i];

/*! Overloaded getModelViewMatrix(GLdouble m[16]) method using a \c GLfloat array instead. */
