Geological Model Related Solutions

scenes to be used

This document mainly introduces what functions can be used for the geological model after it is imported into SuperMap, what effect can be achieved, and what kind of application can it have in the project?
In SuperMap iDesktop, we can modify model colors in batches, edit and modify model textures. In SuperMap iClient3D for WebGL, we have also implemented a variety of geological body real-time analysis functions, including:

function realization

This article introduces step by step from the following three aspects:

1. Edit and modify the material of the geological model

If the imported geological body model has no material, or if you want to modify the material of the model, you can do it in SuperMap iDesktop.

Currently we provide three ways to edit materials:

1.1、Through the "Material Browser" function, select the object to modify the material in real time

Let's take a Geo3DML file as an example to illustrate:

2. Publish model data to data service

2.1 Publish the processed dataset as a data service through SuperMap iServer

3. In SuperMap iClient3D for WebGL, load the data service and realize the real-time analysis function of geological bodies.

By citing the data released in the above steps, relevant real-time analysis functions can be realized according to the relevant interfaces provided.

3.1 Real-time profile analysis

In SuperMap iClient3D for WebGL, observe the internal structural shape of the geological body and the changes along the section plane by sectioning.

3.6 Live Expression - Geological Explosion

Currently, there are two ways to do the geological explosion effect:

1. By way of data service

2. The method of loading local data through dynamic layer

First introduce the way of data service: the way of data service does not require further processing of the model data set, and the service obtained in step 2.2 can be used directly.

How to load local data through dynamic layers:

Currently, the dynamic layer only supports loading files in .s3m and .s3mb format, and does not support files in .json format, so further processing of the model dataset is required.

In SuperMap iClient3D for WebGL, the position of the geological body object is determined by setting the model insertion point, so it is necessary to fill in the position coordinates of the model insertion point on the page. If the data is in a projected coordinate system, it is necessary to convert the projected coordinate system to a geographic coordinate system
and then obtain the coordinates of the insertion point of the model.

1. Create a new dynamic layer and add geological bodies to the corresponding dynamic layer. 

		         var cell1 = '../data/Layer1.s3m'; 
		         var cell2 = '../data /Layer2.s3m'
		         …
                         var layer = new SuperMap3D.DynamicLayer3D(
                          scene._context, [cell1,cell2…]
                          );
                         layer.updateInterval = 500;//Dynamic layer update time
                         layer.enableLocalOffset = false;//Disable model local offsets
                         scene.primitives.add(layer)

2、Write the value of the insertion point obtained in step ①

		         var points = [
                         [11x. 000,3x. 000,-46.56],
                         …
                         ];

3、Set the color and other information of the geological body. If you already have a color, you don’t need to set it again

		         var point1 = points[0];
                         var cellState1 = new SuperMap3D.DynamicObjectState({ 
                     	 id:1, longitude: point1[0], 
                    	 latitude: point1[1], 
                    	 altitude: point1[2],
	                     color:new SuperMap3D.Color(94/255, 179/255, 59/255, 1)
                         });

4、Control the offset of each dynamic layer individually

		           document.getElementById("explode").onclick = function() { 
		            	 keymap[cell1][0].altitude =keymap[cell1][0].altitude+5000; 
		                 keymap[cell1][0].lockOrientation = true;
		                 layer.updateObjectWithModel(
		                       cell1, keymap[cell1
		                       ])
                             …
                             }

The explosion effect achieved through data services, the movement of the geological model has no transition effect; the movement of the geological model has a smooth transition effect through the way of loading local data through dynamic layers.

Remarks

1. When editing model materials, SuperMap iDesktop 10i (2020) version is required to have the function of the material editor.

2. The real-time analysis function of geological bodies mentioned in the document needs the SuperMap_iClient3D_10i(2020) version to support it.

3. The coordinate system of the data set must be a geographic coordinate system. If it is a projected coordinate system, it needs to be converted into a geographic coordinate system before operation.

4. iServer requires version 10.12
