Camera הוא Entity שמאפיין נקודת מבט בסצנה תלת‑ממדית. הוא שולט באופן שבו הסצנה מוצגת על מישור תמונה דו‑ממדי. מצלמה מחוברת ל‑ Node כדי למקם ולסובב אותה בסצנה.

הערות יישום

בגרסת Java FOSS, ה‑ Camera המחלקה מכילה רק בונים — אין יישום של תכונות ספציפיות למצלמה (שדה ראייה, מישור קרוב/רחוק, מצב פרויקט) .

הגבלה בייצוא: יישויות מצלמה הן אינן נכתבות במהלך ייצוא סצנות. ממיר glTF (GltfExporter) מעבד רק Mesh יישויות — צמתים של מצלמה מדולגים בשקט. משמעות הדבר שמצלמה המחוברת לצומת לא תופיע באף קובץ מיוצא. הדוגמה “Read Camera After Import” למטה מראה כיצד לקרוא שמות מצלמה מקובץ מיובא; עם זאת, כתיבת מצלמות חזרה לקובץ חדש אינה נתמכת בגרסה זו.
