Embodiment 1

[0082] Example 1: Combining figure 1 , a virtual reality mobile terminal dynamic time frame compensation rendering system, which includes an application-screen two-level rendering module, a shared buffer rendering module, a vertical synchronization management module, an application running scene recognition module, an interactive behavior recognition module, and a time frame compensation control module module, a system performance configuration module, a GPU and a screen, the application-screen two-level rendering module includes an application frame rendering module and a time frame rendering module, respectively performing application frame primary rendering and time frame secondary rendering; the application running scene The information collected by the recognition module and the interactive behavior recognition module is sent to the time frame compensation control module; on the one hand, the time frame compensation control module is connected to the application rendering ...

Embodiment 2

[0087] Embodiment 2: A virtual reality mobile terminal dynamic time frame compensation rendering method, such as a virtual reality mobile terminal dynamic time frame compensation rendering system described in Embodiment 1, the application frame rendering generates an application frame buffer sequence, and the application frame buffer The latest or most recent application frame is extracted from the sequence for secondary rendering to obtain a time frame, and the time frame is sent to the shared buffer. Under the timing control of the vertical synchronization management module, the screen reads the rendering result of the time frame and refreshes it.

Embodiment 3

[0088] Embodiment 3: a virtual reality mobile terminal dynamic time frame compensation rendering method as described in embodiment 2, the rendering cycle and timing of the application frame are controlled by the time frame compensation control module; the time frame compensation control module passes the application scene recognition module and interactive behavior recognition module to collect optical parameter information and user head position information when the application is running, and at the same time match the preset time frame compensation strategy for compensation operation and performance configuration, combined with figure 2 , the specific process is as follows:

[0089] Step 1: Load the time frame compensation policy file, which defines application frame scheduling rules and performance level configuration rules under different operating scenarios and interactive behaviors;

[0090] Step 2: Read the running scene information, which is provided by the applicati...

Abstract

The invention discloses a dynamic time frame compensation rendering system and a dynamic time frame compensation rendering method for a virtual-reality mobile terminal. The method comprises the following steps of generating an application frame buffer sequence by use of frame rendering, extracting the up-to-date or latest application frame from the application frame buffer sequence, and performing secondary rendering, thereby obtaining a time frame; sending the time frame to a shared buffer; and under sequence control of a vertical synchronous management module, reading a time frame rendering result by use of a screen, and performing updating. By virtue of the design of the shared buffer, a GPU rendering result is directly stored in a cache updated by the screen, so that delay of multi-caching exchange is reduced; by virtue of vertical synchronous time management, the GPU rendering time is controlled, collision between GPU rendering writing and screen update reading is avoided, frames can be normally displayed with low delay, and no splitting is generated.

Description

technical field [0001] The invention relates to the field of virtual reality, in particular to a dynamic time frame compensation rendering method of a virtual reality mobile terminal. Background technique [0002] Virtual reality technology comprehensively utilizes computer graphics, photoelectric imaging technology, sensing technology, computer simulation, artificial intelligence and other technologies, and with the help of various interactive devices, it aims to provide users with a realistic and multi-sensory virtual world. [0003] In recent years, virtual reality technology has developed rapidly, and host-side virtual reality uses high-performance PCs or game consoles as the computing core to provide virtual reality experience. With its powerful hardware, it has been able to bring users a very good immersive experience, but due to its high cost and cumbersome supporting equipment, it has not been widely popularized. In contrast, the threshold for mobile virtual reality...
