cesium-transformer v1.0.11

Cesium Transformer

A powerful npm package built on top of Cesium, enabling advanced geometric transformations for Model, Primitive, and Cesium3DTileset.

Installation

Install the package via npm:

npm install cesium-transformer

Install the package via pnpm:

pnpm install cesium-transformer

Usage

• Transformer({viewer, element, boundingSphere})

  • Applies a geometric transformation to the specified element in the Cesium scene.

  • Parameters:

    • viewer (Cesium.Viewer): The Cesium Viewer instance where the transformation will be applied.
    • element (Cesium.Model, Cesium.Primitive, Cesium.Cesium3DTileset): The target element to be transformed. This can be a model, primitive, or 3D tileset.
    • boundingSphere (Cesium.BoundingSphere): The bounding sphere that defines the area of the element that will be transformed.

  • Example:

    import Transformer from 'cesium-transformer';
    
    const boundingSphere = new Cesium.BoundingSphere(Cesium.Cartesian3.fromDegrees(-75.59777, 40.03883), 1000);
    
    const transformer = new Transformer({
      viewer, element, boundingSphere
    });

    

  • functions

    • changeMode(mode)

      • Changes the current transformation mode to either 'translate', 'rotate', or 'scale'.

      • Parameters:

        • mode (string): The transformation mode to switch to. Accepted values are 'translation', 'rotation', and 'scale'.

      • Example:

         transformer.changeMode('translation');  // Switches to translation mode
         transformer.changeMode('rotation');  // Switches to rotation mode
         transformer.changeMode('scale');   // Switches to scaling mode

    • destory

      • destory the transformer

      • Example:

         transformer.destory()
