Image update method, system, and apparatus
An image update method executed by a render server, includes: acquiring a graphics instruction of a virtual machine, determining a type of the graphics instruction of the virtual machine, if the type of the graphics instruction of the virtual machine is a three-dimensional graphics instruction, sending a drawing instruction to a graphics processing unit to perform rendering processing, acquiring a rendering image corresponding to the graphics instruction of the virtual machine, sending a graphics update instruction to a primary surface management unit of the render server, acquiring an original primary surface of the virtual machine, synthesizing a new primary surface according to the original primary surface of the virtual machine, the first graphics update area, and the rendering image, sending an image corresponding to the new primary surface to a client of the virtual machine.
1. An image update method, comprising:
acquiring, by a render server, a first graphics instruction of a virtual machine, wherein the first graphics instruction of the virtual machine carries a first graphics update area and first graphics update content, wherein the first graphics instruction is one of a plurality of graphics instructions, and wherein the plurality of graphics instructions are in an instruction queue to be performed one by one;
performing, by the render server, the first graphics instruction;
determining, by the render server, whether an execution result of the first graphics instruction of the virtual machine changes an image of a primary surface of the virtual machine;
allocating an execution sequence number to the first graphics instruction of the virtual machine when determining that the execution result changes the image, wherein a graphics update instruction carries the execution sequence number, and wherein the execution sequence number is allocated according to a time sequence of each of the plurality of graphics instructions in a sequential order;
receiving, by a primary surface management unit, the graphics update instruction; and
synthesizing, by the primary surface management unit, a new primary surface corresponding to the graphics update instruction according to the execution sequence number carried in the received graphics update instruction.
2. An image update apparatus, comprising:
a communication interface; and
a processor coupled to the communication interface and configured to:
acquire a first graphics instruction of a virtual machine, wherein the first graphics instruction of the virtual machine carries a first graphics update area and first graphics update content, wherein the first graphics instruction is one of a plurality of graphics instructions, and wherein the plurality of graphics instructions are in an instruction queue to be performed one by one;
perform the first graphics instruction;
determine whether an execution result of the first graphics instruction of the virtual machine changes an image of a primary surface of the virtual machine;
allocate an execution sequence number to the first graphics instruction of the virtual machine when determining that the execution result changes the image, wherein a graphics update instruction carries the execution sequence number, and wherein the execution sequence number is allocated according to a time sequence of each of the plurality of graphics instructions in a sequential order;
receive the graphics update instruction; and
synthesize a new primary surface corresponding to the graphics update instruction according to the execution sequence number carried in the received graphics update instruction.
