The present invention relates to panning a virtual camera in a three dimensional environment. In an embodiment of the present invention, a computer-implemented method pans a virtual camera in a three dimensional environment. In the method embodiment, a first point is determined on a three dimensional model in the three dimensional environment. According to the first point, the three dimensional model, and a position of a virtual camera in the three dimensional environment, a virtual surface is determined. A second point is determined on the virtual surface. Finally, a location of the three dimensional model is changed according to the first point and the second point.

The invention belongs to the field of three-dimensional parking equipment, and particularly relates to lateral moving type double-layer parking equipment. The equipment consists of a ground rail, a framework, a slide sleeve, a lifting device, a first floor table plate, a second floor table plate, a first pushing device and a second pushing device. A framework type structure is used; the structure is simple; the reliability is high; the stress of the second floor table plate is balanced; the deformation quantity of the second floor table plate is small; the lifting device uses single-motor four-point lifting; the synchronicity and the stability are good; the first floor table plate can outwards (leaving far away from the pushing device) or inwards (approaching to the pushing device) translate along the ground rail under the effect of the first pushing device; and the framework drives the second layer table plate to outwards or inwards translate under the effect of the second pushing device. The first floor table plate realizes the car storage and taking through the translation action; and the second floor table plate realizes the car storage and taking through the matching of two actions of the translation and the ascending and descending. The lateral moving type double-layer parking equipment has the advantages that the structure is simple; the operation is easy; safety and reliability are realized; the running direction of a car does not need to be changed by using the equipment; the car storage and taking can be realized without rotating the table plates; the car storage and taking process is simple and fast; and the car storage and taking efficiency is high.

The invention relates to a connecting and locking device, in particular to a connecting and locking device for building formworks. The connecting and locking device for the building formworks is good in connecting stability and capable of connecting formworks with different angles. The connecting and locking device for the building formwork comprises a T-shaped frame, a first connecting spring, a first hinge block, a second hinge block and the like, a cavity is formed in the right side of the T-shaped frame, the first hinge block is arranged in the cavity in a sliding mode, the first connecting spring is connected between the first hinge block and the T-shaped frame, and a shaft rod rotationally penetrates through the right portion of the first hinge block; the shaft rod is sleeved with a second hinge block. The formworks are fixed through the screws, the two formworks are made to be close to each other, then the hollow blocks are clamped through the clamping plates, so that the formworks can be stably connected together, and the formworks with different angles can be connected through cooperation of the first hinge blocks and the second hinge blocks and rotation of the T-shaped frames.
