In the proposed technique, three fundamental GO components of direct, reflected and transmitted rays are considered. Taking into account three components only, one can utilize the convenient binary tree with the source as root for reflected and transmitted rays. The node numbers of the tree correspond to species of the rays, so one can distinguish each rays with different reflection\/transmission history for a shooting angle. Also, two or much more adjacent rays passing through the reception sphere in a pixel are appropriately counted or uncounted.In addition, ``collective\" reflected and transmitted coefficients, which include the internal multiple reflection effects of indoor walls, are introduced for further accuracy improvement.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e原稿種別: \u003c\/strong\u003e日本語\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003ePDFファイルサイズ: \u003c\/strong\u003e686 Kバイト\u003c\/p\u003e","brand":"IEEJ-PDF","offers":[{"title":"PDFダウンロード（一般価格330円\/会員価格220円） \/ A4 \/ 5","offer_id":46362603880687,"sku":"IEEJ-EMT11120-PDF","price":330.0,"currency_code":"JPY","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0718\/9512\/2159\/files\/IEEJ-PDF_8fcdbb1e-0fd9-498c-9413-d5d0d703b7b9.png?v=1743632342","url":"https:\/\/ieej.bookpark.ne.jp\/products\/ieej-emt11120","provider":"電気学会 電子図書館","version":"1.0","type":"link"}
