Detailed Description

The present invention is further described below in conjunction with the following figures and specific examples so that those skilled in the art may better understand the present invention and practice it, but the examples are not intended to limit the present invention.

The invention provides a data visualization-based three-dimensional map implementation method, which utilizes a three-dimensional design tool to manufacture a data visualization three-dimensional map, namely, acquiring a map contour, determining the pixel size of an acquired map picture, setting the plane size of the map, setting the plane direction as a-Z direction, determining a map contour spline, adjusting and extruding each map model in the map through the spline, selecting the extruded map model, and generating a corresponding target file;

According to the method, the data visualization three-dimensional map is manufactured by using the three-dimensional design tool, and is displayed by using the video editing design tool, so that the problems of poor display substitution feeling of the plane map and the like in various large screens needing to display the map can be solved.

In particular applications, the process in some embodiments of the method of the invention is as follows:

s1: a planar graph of a three-dimensional map to be made is selected, and a required map can be downloaded through Baidu encyclopedia search or http:// datav. The pixel size of the obtained picture is determined, taking the map of china as an example, the size of the pixel size is 1028 × 1028 px.

S2: with the C4D tool "create object-plane", set the plane size to the same physical dimensions as the picture size described above, where cm corresponds to px, as long as the scale is correct, and set the direction of the plane to the-Z direction, otherwise no adjustment is required.

S3: and (3) newly building a material ball, loading a map outline picture before loading at a 'material editor-color-texture' position, and setting the size to be 2-3 times of the size of the original picture at the 'material editor-editing-texture preview size' position, so that the preview effect picture becomes clearer.

S4: in the "middle view-space-front view", a plan view is selected instead of a perspective view. Select "create spline-brush" (just like the pen tool in PS), draw the map outline out of the spline with the brush. And meanwhile, the point difference value mode of the spline is adjusted to be uniform, so that the problem of the model when the material is added in the later period is prevented.

S5: adding 'creating-generating-extruding' to the selected sample strip, adjusting the extrusion width 'object-moving' to be 60cm, simultaneously selecting 'capping-type-quadrilateral', checking a standard grid, and setting the width to be 8 cm.

S6: and selecting the squeezed map model, clicking the middle of the mouse to select all layers, and changing the map model into an editable object by 'right mouse button-connecting object + deleting'. Select "File-export-Wavefront OBJ" and generate the map model as a target file for OBJ.

S7: after the steps are completed, the map three-dimensional modeling can be manufactured and completed in C4D. Other provinces and city maps can be sequentially manufactured through the steps.

S8: the AE tool is opened, new-solid layer-effect-Video copy-Element, and E3D effect is newly created. The settings page Scene interface Scene Setup is entered in the E3D plug-in.

S9: importing the obj file generated by us by using C4D, and setting as follows:

the nationwide map and provinces are classified into different groups,

changing-the direction (90 degrees, 180 degrees, 0 degrees),

transformation-ratio (60%, 60%, 60%),

material-basic set-color (#000), diffusion 1.0, ambient 1.0, gloss 100%,

material-reflectivity-strength of 0,

material-refractive index-intensity 0,

texture-illumination-color (# OABCFF), intensity-300%, fresnel offset 1.49.

S10: the method comprises the following steps of building a new solid layer, creating an effect, Video coding, Saber and selecting a pen tool, and drawing the appearance of a map, the boundary line of a city and the outline. The Saber attributes are set for the outer contour color #005AFF and the inner contour province color # E2C 136. Adjusting the light emitting property: the Glow Intensity was 20%, Glow Spread was 0.28, Glow Bias was 0.40, and Core Size was 1.00.

S11: adding a province elevation effect 'Element-group 1-particle copy-position Y', and adding a key frame animation to the position to enable the province to be elevated at a specific time; adding camera animation, "Transform-Position," adds keyframe animation to the Position attribute so that when a certain province is selected, the shot will have a pull-in effect.

When the method is implemented, after the map contour model is obtained, the contour line is redrawn in the C4D, excessive turning points and brush pen handle adjustment are reduced as much as possible in the drawing process, and the line has no redundant points. And modifying the line point difference mode to enable points on the line to be uniformly distributed, so as to prepare for next extrusion.

After the lines are extruded, the upper and lower caps of the extrusion model have no subdivision lines, and when the model type is changed into a quadrilateral and standard grid, the skeleton with grid lines added to the upper and lower caps of the model is equivalent to generate a model capable of being exported.

After the obj model is available, the existing obj model is introduced by adding the E3D effect to the solid layer in AE, and the texture is adjusted to complete the creation in E3D. And simultaneously, a Saber light effect is added through another solid layer, and the outline of the rotated model is drawn. And after the model is manufactured, adding keyframe animation, adjusting the position of a camera, and finally exporting a three-dimensional map to be applied to a large visual screen.

The three-dimensional map manufactured by the steps can be applied to various large screens needing to display the map, the three-dimensional map is convenient to modify, and after parameters are set, the map is changed only by replacing obj. For designers familiar with the design tool, the method can be used for realizing the through-fusion, modifying the color scheme and matching data visualization large screens with different styles.

For design enthusiasts and even front-end developers, the three-dimensional map meeting the requirements can be manufactured through the steps of the method.
