정사각형 카메라 클리핑이있는 Viewport3D

Question

정사각형 카메라로 ViewPort3D를 사용하는 경우 아래의 두 번째 링크에서 볼 수 있듯이 3D 모델이 클리핑됩니다. 보기가 원근 카메라를 기반으로하고, 정사각형 카메라를 사용하더라도 그 뒤에 무엇이 보이지 않는 것과 같습니다.

View of the entire 3D model

Perspective view & Orthographic view

는이 문제를 해결하는 방법에 대한 아이디어를

Used code to generate pictures above (toggling Orthographic to True/False)

Answer 1

: 나는 실제로 해결책을 발견, 당신은 단지, -Infinity에 직교 카메라의 NearPlaneDistance 설정 아래 코드를 볼 필요가 당신. 마지막으로 여러 솔루션을 테스트하여 솔루션을 찾을 수있었습니다.

당신은 증가에 있거나 PerspectiveCamera의 FarPlaneDistance 속성을 정의합니다.

행운을 빕니다
