This article mainly shows you "how to load a single model in Cesium", the content is simple and clear, hoping to help you solve your doubts, let the editor lead you to study and learn "how to load a single model in Cesium" this article.
Cesium supports loading a single 3D model, the commonly used model format is: gltf,glb, these models can be converted from 3dmax, obj and other 3D model format. The official website of Cesium also lists the ways to load a single 3D model, according to the detailed code.
The detailed code is in the Cesium example: 3D Models.html page
The model file for the sample is in the folder of: SampleData
The following is the detailed code for loading the model:
/ / location information, x, y, height information
Var position = Cesium.Cartesian3.fromDegrees (- 123.0744619, 44.0503706, height)
/ / the three directions of the model and the three directions of the three corners in the three-dimensional space can be seen in the figure above.
/ / schematic diagram of small aircraft (where direction corresponds to heading and tilt corresponds to pitch)
Var heading = Cesium.Math.toRadians
Var pitch = 0
Var roll = 0
Var hpr = new Cesium.HeadingPitchRoll (heading, pitch, roll)
/ / to make a conversion according to the position and the set corner information
Var orientation = Cesium.Transforms.headingPitchRollQuaternion (position, hpr)
/ / A single object is usually placed in an entity, and a solid object is added
Var entity = viewer.entities.add ({
/ / set position and steering information
Name: url
Position: position
Orientation: orientation
Model: {
/ / the path of the model
Uri: url
/ / scale of the model
Scale:1.0
/ / the smallest pixel size
MinimumPixelSize: 128
/ / maximum display scale
MaximumScale: 20000
}
});
