Embodiment 1

[0022] The invention provides a method for realizing special effects in a three-dimensional scene, such as figure 1 shown, including the following steps:

[0023] Step S1: adding special effects to the 3D scene.

[0024] First, a special effect attribute node is added to a 3D scene containing multiple primitives, and scene-level special effects are added to the special effect node, including 3D scene camera special effects and 3D scene fade-in and fade-out special effects.

[0025] Step S2: Adjust the parameters of the special effects added to the 3D scene.

[0026] According to whether the camera special effect or the fade-in and fade-out special effect is added on the 3D scene, different parameters are provided for the user to choose. Edit the 3D scene camera special effects and the 3D scene fade-in and fade-out special effects added in step S1 and modify their special effect attribute parameters.

[0027] Step S3: Render the 3D scene through the rendering engine. Before...

Embodiment 2

[0032] Embodiment 2 of the present invention will be described in detail by taking the example of adding a special effect of a camera in a three-dimensional scene, as figure 2 shown, including:

[0033] Step S1: Add the newly created camera out effect to the 3D scene. Add a special effect attribute node in the 3D scene to make it support special effects like ordinary primitives, and then give the camera special effects to the special effect attribute node.

[0034] Step S2: Adjust the parameters of the special effect of the camera added in step S1. Camera stunt parameters include: camera position, angle, motion trajectory, which can be set flexibly by users. It also provides many saved templates, such as translation, rotation around any axis, pitch, yaw, roll, walk, pan and lift, etc. Some simple parameters are provided in these templates to fine-tune the effects of various templates, making It is convenient for the user to use the selected stunt.

[0035] Step S3: Use th...

Embodiment 3

[0039] Embodiment 3 of the present invention will take the example of adding fade-in and fade-out special effects in a three-dimensional scene to describe in detail, as shown in image 3 shown, including:

[0040] Step S1: Add the newly created fade-in and fade-out effect to the 3D scene; add an out-effect attribute node in the three-dimensional scene, and then assign a fade-in and fade-out effect to the out-effect attribute node.

[0041] Step S2: Edit the fade-in and fade-out special effects added in step S1; including: fade-in and fade-out frequency, color change, and change direction, etc., which can be set flexibly by the user. The saved templates provided include fade-in, fade-out, flashing, etc. In the saved templates, the effects of various templates can be fine-tuned through some simple parameters, so that users can use this special effect very conveniently.

[0042] Step S3: Use the rendering engine to render the scene containing the fade-in and fade-out effects acc...

Abstract

The invention discloses a method for realizing special fade-in and fade-out effects in a three-dimensional scene. The method comprises the following steps that: a special fade-in and fade-out effect attribute node is added into a three-dimensional scene and special fade-in and fade-out effects are attached to the attribute node; special effect parameter adjustment is carried out on the special effects that are added into the three-dimensional scene; it is determined whether there is a special fade-in and fade-out effect attribute node and special effects in the three-dimensional scene and the three-dimensional scene is rendered by a rendering engine; and the rendered image is displayed. According to the method provided in the embodiment of the invention, special fade-in and fade-out effect processing with a scene level is realized; operation steps are simplified; and user demands can be met. Moreover, multiple adjusting modes of special fade-in and fade-out effects with a scene level are provided, thereby enriching special effects.

Description

technical field [0001] The invention relates to the field of broadcasting and television, in particular to a method for realizing special effects in a three-dimensional scene. Background technique [0002] Under the premise of the rapid development of video production in the field of broadcasting and television, there are higher requirements for any link of video production. An important link in the process of video subtitle production special effects is the editing and processing of special effects in 3D scenes. The main special effects in 3D scenes are camera special effects and fade-in and fade-out special effects. [0003] The camera out effect of the 3D scene contains 4 camera vectors: right vector, up vector, view vector and position vector to define the position and orientation of the camera relative to the world coordinate system. These vectors essentially define a local coordinate system for the camera described relative to the world coordinate system. Since the r...
