Problems solved by technology

[0003] In related technologies, in the process of displaying 3D text, when the number of text input by the user is large, it is easy to cause the generated 3D text to be partially truncated, or the 3D text can be completely displayed during generation. When the 3D text is rotated, part of the 3D text is cut off, which greatly affects the user experience

Embodiment Construction

[0026] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0027] In the related art, in the process of displaying 3D characters, the generated 3D characters are easily partially truncated and cannot be displayed. According to the 3D character display method of the embodiment of the present invention, firstly, the user's input instruction is obtained to generate the input instruction The corresponding three-dimensional vertex data of 3D characters, wherein, the three-dimensional vertex data of 3D characters includes the coordinate value of each vertex in the 3D characters, thus, the farth...

Abstract

The invention discloses a 3D character display method, medium, equipment and device. The method comprises the following steps: obtaining an input instruction of a user, so as to generate corresponding3D character three-dimensional vertex data according to the input instruction; calculating the longest distance between the vertex of the 3D character and the rotation center according to the 3D vertex data of the 3D character; constructing a sphere with the rotation center as the sphere center and the farthest distance as the radius; calculating the distance between the sphere center and the viewpoint of the camera according to the radius of the sphere and the visual angle of the camera when the sphere is tangent to the square conical visual space of the camera; setting the camera accordingto the distance between the center of sphere and the viewpoint of the camera, and projecting the 3D characters onto a canvas through the set camera so as to display the 3D characters; according to thetechnical scheme, the 3D characters can be prevented from being cut off during display, complete display of the 3D characters is guaranteed, user experience is improved, and the canvas can be utilized to the maximum extent no matter how many the characters are.

Description

technical field [0001] The invention relates to the technical field of 3D text processing, in particular to a 3D text display method, a computer-readable storage medium, a computer device and a 3D text display device. Background technique [0002] 3D text is a text display form that presents text in a three-dimensional and more vivid way. Compared with ordinary two-dimensional text, it has a prominent visual effect, so it is recognized by more and more people. [0003] In related technologies, in the process of displaying 3D text, when the number of text input by the user is large, it is easy to cause the generated 3D text to be partially truncated, or the 3D text can be completely displayed during generation. When the 3D text is rotated, part of the 3D text is cut off, which greatly affects the user experience. Contents of the invention [0004] The present invention aims to solve one of the technical problems in the above-mentioned technologies at least to a certain ext...
