WebMy camera class has standard rotate and translate functions which call glm::rotate and glm::translate respectively void camera::rotate (float amount, glm::vec3 axis) { m_view = glm::rotate (m_view, amount, axis); } void camera::translate (glm::vec3 dir) { m_view = glm::translate (m_view, dir); } Webrotated_point = orientation_quaternion * point; … but if you want to compute your Model Matrix, you should probably convert it to a matrix instead. Note that the center of rotation is always the origin. If you want to rotate around another point: rotated_point = origin + (orientation_quaternion * (point-origin));
