Embodiment Construction

[0046] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0047] Figure 4It is a schematic flowchart of the method for displaying real-time shadows in virtual reality according to the present invention. see Figure 4 , the method mainly includes:

[0048] Step 401 : Select key time points according to scene illumination changes; calculate shadow values ​​for each key time point to obtain a shadow map, and use the frame containing the shadow map as a key frame corresponding to the key time point.

[0049] Step 402, when realizing real-time shadow display, determine the current time point, read two key frames corresponding to two key time points before and after the current time point, and perform interpolation calculation on the shadow maps in the two key frames, A real-time shadow map of the frame corresponding to the current time point is obtained, wherein the interpolation calculated b...

Abstract

The invention discloses a method for displaying a real-time shadow in virtual reality. The method comprises the following steps: key time points are selected according to illumination change of a scene; shadow values are calculated for the key time points, a shadow map is obtained, and frames containing the shadow map are taken as key frames corresponding to the key time points; the current time point is determined when the real-time shadow is displayed, two key frames corresponding to the two key time points before and after the current time point are read, interpolating calculation is performed on the shadow map in the two key frames, and the real-time shadow map of the frame corresponding to the current time point is obtained, wherein an interpolation for the interpolating calculation is determined according to the interval between the current time point and the key time points before and after the current time point. Consumption of computing resources is reduced while the real-time shadow effect can be realized.

Description

technical field [0001] The present application relates to the technical field of virtual reality, in particular to a method for displaying real-time shadows in virtual reality. Background technique [0002] Virtual reality technology is a computer simulation system that can create and experience a virtual world. This technology uses a computer to generate a simulated environment. The user is immersed in the environment. [0003] At present, virtual reality technology is widely used in application scenarios such as 3D games and simulation exercises. In virtual reality technology, it is often necessary to shape and render the virtual environment to make the virtual environment as realistic as possible. [0004] Shadows are a very important part of computer graphics, whether in 3D animation or 3D games, it is through shadows that many vivid and even bizarre visual effects are created. In the virtual reality world of computer graphics, it is the combination of shadows and oth...
