gemini-viewer is a WebGL based JS SDK, it is built on top of three.js. It provides following viewers:
Used to view 2d drawings and PDF. For dwg, we need to convert it to dxf first (there is a dwg2dxf.exe worker). It supports most common entity types, it supports OLE and region via dwg2dxf; It supports common line types; It supports common hatch styles; It support line width;
Used to view 3d BIM models. It supports formats including gltf, obj, fbx, ifc, dae, etc. Its features including measurement, section, display outline, orthographic camera, selection, etc.
Used to view panoramas. It supports viewing a panorama with 1 image, 6 images, or 24 images; It supports viewing a serials of panoramas; It supports hotpoints;
To install from npm:
npm install @pattern-x/gemini-viewer-threejs
import { DxfViewer, DxfViewerConfig, ModelConfig } from "@pattern-x/gemini-viewer-threejs";
const viewerCfg: DxfViewerConfig = {
containerId: "myCanvas",
enableSpinner: true,
enableLayoutBar: true,
};
const modelCfg: ModelConfig = {
modelId: "id_0",
name: "sample",
src: "http://www.abc.com/sample.dxf",
}
const fontFiles = ["http://www.abc.com/hztxt.shx", "http://www.abc.com/simplex.shx"];
const viewer = new DxfViewer(viewerCfg);
await viewer.setFont(fontFiles);
await viewer.loadModelAsync(modelCfg, (event) => {
const progress = (event.loaded * 100) / event.total;
console.log(`${event.type}: ${progress}%`);
});
console.log("Loaded");
viewer.goToHomeView();
DxfViewer features includes: load and view one or more dxf files, basic mouse/key operations, layouts, layers, distance/area/angle measurements with osnaps, markups, hotpoints, comparison, undo/redo for measurements/markups, zoom to selected area, screenshots, set background color, etc.
