Embodiment

[0020] figure 1 It is a flow chart of a method for realizing material plate special effects provided by an embodiment of the present invention.

[0021] Such as figure 1 Said, the method includes the following steps:

[0022] Step 101, acquire video data, material texture data and opacity Alpha texture data, the material texture data and opacity Alpha texture data are static images, and the material texture data and opacity Alpha texture data are stored in the hard disk in the form of files superior.

[0023] Step 102, generating normal line texture data according to the material texture data.

[0024] Step 103: Overlay the material texture data with the video data, and call the opacity Alpha texture data to control the opacity of the material texture data.

[0025] Before the superposition of the material texture data and the video data includes: constructing a tetrahedron on the xyz axis space, and mapping the material texture data on the tetrahedron, the initial length ...

Abstract

The invention discloses a method for realizing special effects of material boards. The method comprises the following steps of: acquiring video data, material texture data and nontransparency Alpha texture data; generating normal texture data according to the material texture data; superposing the material texture data and the video data and calling the nontransparency Alpha texture data to control nontransparency of the material texture data; controlling the strength of concave-convex impression in the material texture data by calling the normal texture data and adjusting illumination information, and acquiring blended data; and rendering the blended data and acquiring video special-effect data after being added with the special effects of the material boards. By the method, the quality of pictures is greatly improved, and concave-convex impression of the pictures is improved.

Description

technical field [0001] The invention relates to the field of video editing, in particular to a method for realizing material plate special effects. Background technique [0002] Movies, TV series and other films watched by the audience now will have special effects added through post-production. In order to highlight the texture of the film, material plate special effects are usually added. Now audiences watching movies are not limited to the storyline of the movie, but more to the visual shock brought by the special effects added to the movie. Therefore, more special effects were gradually developed. [0003] In order to reflect the uneven visual effects in the real environment, such as folds, rough brick walls, mottled city walls, etc., it is urgent to meet the needs of users in video editing. As a two-dimensional image, the video image cannot show this effect. The material plate effect is a method for simulating rough surfaces based on 3D scenes. Through different mat...
