Embodiment Construction

[0023] A preferred embodiment of the present invention is Figure 1 to Figure 4 shown. First, some concepts involved in the present invention are briefly explained. The "rendering lens" mentioned herein refers to a kind of virtual lens in the three-dimensional animation production software; Virtual shooting in the scene to generate corresponding digital images, the effect is similar to the process of shooting with a real camera to generate photos or movies; "rendering plane" refers to the imaging surface when rendering with the rendering lens, similar to It is based on the film of a real camera; "geometric plane" refers to a plane with a certain shape and size set in the 3D animation production software.

[0024] Step 101: if figure 1 As shown, in the 3D animation production software, the 9 rendering planes (A1, A2, ..., A9) corresponding to 9 (that is, N=9) identical plane rendering lenses are connected in sequence to form a 180-degree arc , perspective points all coincide...

Abstract

The invention relates to a method for producing digit spherical movie, wherein the romance plane with N romance lens are connected to form one romance surface whose one perspective point is at the center; then building another cylinder romance surface to be rotated for alpha degrees; then building M connected seamless cylinder romance surfaces, to form one spherical romance surface whose perspective point is at the center and formed by N*M romance lens; using said N*M romance lens to romance the three-dimension field to generate relative N*M images; then building N*M geometrical surfaces consistent with N*M romance planes, then using pattern projection to project the image to the geometrical planes to form one spherical image; then using secondary romance lens to process secondary romance to generate the spherical movie.

Description

technical field [0001] The invention relates to digital movie technology, in particular to a method for making a digital dome movie using computer three-dimensional animation software to make a dome movie. Background technique [0002] As an emerging computer art in recent years, three-dimensional (3D) animation has developed rapidly and has been widely used in many industries. Three-dimensional animation is a virtual three-dimensional space given by the computer with special animation software. By building an object model, placing the model on the stage of this three-dimensional space, illuminating it with lights from different angles, and then endowing each part with dynamic and Intense texture gets the effect. When making 3D animation, it is first necessary to create a 3D model of the object and the background, then let these objects move in 3D space, and then use the virtual "camera" in the 3D animation software to shoot the movement process of the object, and put on th...
