API Reference > imodeljs-backend > iModels > IModelDb > exportGraphics exportGraphics Method Export meshes suitable for graphics APIs from arbitrary geometry in elements in this IModelDb. Requests can be slow when processing many elements so it is expected that this function be used on a dedicated backend, or that shared backends export a limited number of elements at a time. Vertices are exported in the IModelDb's world coordinate system, which is right-handed with Z pointing up. The results of changing ExportGraphicsOptions during the ExportGraphicsOptions.onGraphics callback are not defined. Example that prints the mesh for element 1 to stdout in OBJ format const onGraphics: ExportGraphicsFunction = (info: ExportGraphicsInfo) => { const mesh: ExportGraphicsMesh = info.mesh; for (let i = 0; i < mesh.points.length; i += 3) { process.stdout.write(`v ${mesh.points[i]} ${mesh.points[i + 1]} ${mesh.points[i + 2]}\n`); process.stdout.write(`vn ${mesh.normals[i]} ${mesh.normals[i + 1]} ${mesh.normals[i + 2]}\n`); } for (let i = 0; i < mesh.params.length; i += 2) { process.stdout.write(`vt ${mesh.params[i]} ${mesh.params[i + 1]}\n`); } for (let i = 0; i < mesh.indices.length; i += 3) { const p1 = mesh.indices[i]; const p2 = mesh.indices[i + 1]; const p3 = mesh.indices[i + 2]; process.stdout.write(`f ${p1}/${p1}/${p1} ${p2}/${p2}/${p2} ${p3}/${p3}/${p3}\n`); } }; iModel.exportGraphics(({ onGraphics, elementIdArray: ["0x1"] })); exportGraphics(exportProps: ExportGraphicsOptions): DbResult Parameter Type Description exportProps ExportGraphicsOptions Returns - DbResult 0 if successful, status otherwise Defined in core/backend/src/IModelDb.ts Line 1252 Last Updated: 11 June, 2024
