Embodiment 1

[0060] This embodiment uses a two-dimensional picture as a scene image, and discloses a dome display and adjustment method based on computer graphics, including the following steps:

[0061] S1: Create a plane in the Unity3D engine, adjust the length and width of the plane, and spread the plane to the entire screen;

[0062] Create a material in the Unity3D engine, and introduce a static or dynamic 2D image into a 3D scene by using the system's preset Standard shader file or a custom shader file as needed;

[0063] This embodiment adopts a custom ocean shader file, adds the color adjustment and normal map of the continent, and adds effects such as seawater flow and offshore gradient color simulation, thereby realizing a dynamic seawater effect and making the earth effect more realistic and delicate;

[0064] S2: Establish the shader material file for adjusting the scene image, and write the shader file of the shader material file through the CG language, use the shader file to...

Embodiment 2

[0070] This embodiment uses ordinary video as the scene image, and discloses a dome display and adjustment method based on computer graphics, including the following steps:

[0071] S1: Create a GameObject in the Unity3D engine, and mount the inherent component in the engine-VideoPlayer;

[0072] Drag the video resource to be converted into the VideoClip property of the VideoPlayer component;

[0073] Create a RenderTexture and drag it into the TargetTexture property of the VideoPlayer component;

[0074] Create a new RawImage, drag the previously created RenderTexture into the Texture property of RawImage;

[0075] S2: Create a shader material file for adjusting the scene image, drag the newly created shader material file into the Material property of RawImage, use CG language to write the shader file of the shader material file, and use the shader file to import The scene image is processed, and the image color brightness variable, the polar coordinate radius variable, the...

Embodiment 3

[0080] This embodiment uses the three-dimensional underwater world as the scene image, and discloses a dome display and adjustment method based on computer graphics, including the following steps:

[0081] S1: Create a three-dimensional underwater world in the Unity3D engine, with marine animals swimming around the seabed;

[0082] S2: Establish the shader material file for adjusting the scene image, and write the shader file of the shader material file through the CG language, use the shader file to process the imported scene image, and convert the image color brightness variable, extreme Coordinate radius variables, edge blurring variables, and rotation angle variables are opened and become visual adjustment controls;

[0083] The processing of the scene image by the shader file includes: converting the scene image into a polar coordinate image, and calculating the image color brightness, polar coordinate radius, edge blurring degree, and rotation angle;

[0084] S3: Create...

Abstract

The present invention relates to a ball screen playing and adjusting method based on computer graphics, which is characterized in that it comprises the following steps: S1: creating a scene image in a three-dimensional engine; S2: creating a material file, writing a shader file, and converting the scene image For a polar coordinate image, calculate the image color brightness, polar coordinate radius, edge blurring degree, and rotation angle, and open the image color brightness variable, polar coordinate radius variable, edge blurring degree variable, and rotation angle variable as visual adjustment controls; S3: Perform image effect processing on the scene image; S4: Use the visual adjustment control to make preliminary adjustments to the scene image; S5: Establish terminal control software, and perform visual adjustment on the scene image on the terminal control interface. The invention expands the resources played by the dome screen, simplifies the calculation process of resource conversion, and improves the fluency and expressive force of the play of the dome resource.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a dome display and adjustment system based on computer graphics. Background technique [0002] Ball screen technology is a new display technology, which breaks the previous limitation that projected images can only be flat regular graphics, and meets the needs of aesthetic fatigue and innovative personalized display. The screen of the dome screen is a spherical screen, and the screen can be inside or outside the sphere. The image is projected onto the entire spherical screen, and the audience can see that the entire dome screen is covered with images. Compared with ordinary screens, it has a more shocking performance effect and is easy to attract the audience's attention. [0003] Due to the different arrangement of pixels between the dome screen and the ordinary screen, the ordinary image will be distorted during playback. In response to this situation, there are vari...
