Embodiment Construction

[0031] The present invention will be further described below in conjunction with embodiment, but protection scope of the present invention is not limited to this:

[0032] combine figure 2 .

[0033] S1, scene drawing;

[0034] S2. Obtain the rendering result Colorbuffer;

[0035] S3. Carry out frame-chasing algorithm time-distortion graphics calculation according to the parameters of the hardware device;

[0036] S4. Draw a staring white point at a certain spatial position according to the relationship between the line of sight and the scene;

[0037] S5. Outputting the result to the screen.

[0038] The present invention puts the drawing of the staring white point in the thread of the frame-tracking algorithm such as ATW. This thread usually has a high priority in VR drawing, and there is no obvious delay in drawing, which can well solve the sense of jitter.

[0039] Principle explanation: In a three-dimensional VR scene, the gaze white point can be understood as the d...

Abstract

The invention discloses a virtual reality-based space point mapping method of applying an anti-distortion grid. The method is characterized by changing a drawing time sequence of a gaze white point, and drawing the gaze white point in an asynchronous timewarp (ATW) thread. The method is based on asynchronous timewarp and other frame chasing algorithms, carries out deep optimization on drawing of the gaze white point on the basis of the algorithm, and will not increase a calculation amount on a current mainstream mobile-VR solution and also does not need to modify workflows of the current ATW and other frame chasing algorithms while the gaze white point can be smoothly drawn.

Description

technical field [0001] The invention belongs to the technical field of virtual reality, and in particular relates to a spatial point mapping method based on a virtual reality application anti-distortion grid. 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. In recent years, with Facebook's acquisition of Oculus for $2 billion, virtual reality technology has attracted widespread attention around the world. In current virtual reality applications, the user usually needs to indicate the relative relationship of the user's line of sight in the 3D scene through a middle line of sight gaze point. This gaze point is used to indicate the interaction relationship between the current line o...
