問題文
Several specialists have edited the same map in parallel: some added or removed objects, others changed the geometry of the terrain. Which defect does the syllabus name as typical for that stage?
選択肢
- Sunken objects appear, because the parallel editing affects the height of the placed models.
- Delayed switches appear, because the weak hardware affects the timing of the substituted meshes.
- Noticeable seams appear, because the automatic mapping affects the color of the shared edges.
- Duplicated polygons appear, because the careless copying affects the group of the drawn faces.
