Problems solved by technology

see figure 2 , the disadvantage of this way of using model roads is that the road model is pre-made, and the terrain of the ground is often undulating, and the road model cannot just fit the ground to be combined, so there may be If there are gaps between the road model and the ground, the simulation effect is not good

Embodiment Construction

[0049] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0050] The core idea of ​​the present invention is to quickly generate a road grid that fits the ground terrain, separate road and ground editing, reduce the difficulty of ground editing without limiting the diversity of the ground. At the same time, the simulation effect of the road is improved to avoid the gap between the road and the ground.

[0051] image 3 It is a schematic flow chart of a method for generating a virtual reality three-dimensional road according to the present invention, see image 3 , the method includes:

[0052] Step 301 determines the road basic mesh conforming to the road outline.

[0053] Step 302: Based on the basic road grid, within the range of the ground grid where the basic road grid is located, a dynamic grid segmentation algorithm is used to generate a three-dimensional road grid that fits the gro...

Abstract

The invention discloses a method for generating a virtual-reality three dimensional road, and the method comprises the steps: determining a road basic grid according with the contour of a road; generating a three-dimensional road grid, attached to the ground, in the ground grid range where the road basic grid is located based on the road basic grid through employing a grid dynamic segmenting method; rendering a three-dimensional road based on a three-dimensional road grid, and obtaining the three-dimensional road attached to a three-dimensional ground. The method can enable the three-dimensional road to be attached to a three-dimensional ground, reduces the calculation resources under the condition of guaranteeing the simulation effect, and improves the rendering efficiency.

Description

technical field [0001] The present application relates to the technical field of computer virtual reality, in particular to a method for generating a virtual reality three-dimensional road. 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] In the rendering and display technology of the 3D virtual environment, it is usually necessary to display roads in the virtual scene. These roads can be paved with fixed road models, or multiple textures can be used on the ground to create road effects by...
