Embodiment Construction

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

[0032] Combine figure 2 .

[0033] S1, scene drawing;

[0034] S2, get the rendering result Colorbuffer;

[0035] S3. According to the parameters of the hardware device, perform the frame tracking algorithm time warp graphics calculation;

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

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

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

[0039] Principle description: In a three-dimensional VR scene, the staring white point can be understood as the display performance of the intersec...

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 field of virtual reality technology, and specifically is a space point mapping method based on virtual reality application anti-distortion grid. Background technique [0002] Virtual reality technology comprehensively utilizes computer graphics, photoelectric imaging technology, sensor technology, computer simulation, artificial intelligence and other technologies, and with the help of various interactive devices, aims to provide users with a realistic, multi-perceptual virtual world. In recent years, with Facebook's acquisition of Oculus for US$2 billion, virtual reality technology has begun to attract widespread attention worldwide. Current virtual reality applications usually require the user to indicate the relative relationship of the user's gaze in the three-dimensional scene through an intermediate gaze point. This gaze point is used to indicate the interaction between the current gaze and the scene, such as selecting int...
