TIP technology accelerated by GPU

To accelerate rendering speed of TIP(Tour Into the Picture),a method is proposed based on GPU(Graphics Processing Unit).In the method,the operation ability of GPU is fully used,that is,the process of extracting background texture is transferred from CPU to GPU,the fixed pipelines of GPU are used to implement TIP rendering,and the depth calculation and texture extraction of foreground model are processed by CPU.So parallel operation can be implemented for GPU and CPU.It means that the method can improve texture projection speed effectively,accelerate TIP rendering speed and can satisfy the real-time roaming requirement of virtual scene for customers.
