描述

add_scene_3d_cameraadd_scene_3d_cameraAddScene3dCameraAddScene3dCameraAddScene3dCameraadd_scene_3d_camera adds a new camera to the 3D scene Scene3DScene3DScene3DScene3Dscene3Dscene_3d and returns the index of this camera in CameraIndexCameraIndexCameraIndexCameraIndexcameraIndexcamera_index. The camera parameters of the camera must be given in CameraParamCameraParamCameraParamCameraParamcameraParamcamera_param. By default the new camera is located at the origin of the world coordinate system. The pose of the camera CameraIndexCameraIndexCameraIndexCameraIndexcameraIndexcamera_index can be set with set_scene_3d_camera_poseset_scene_3d_camera_poseSetScene3dCameraPoseSetScene3dCameraPoseSetScene3dCameraPoseset_scene_3d_camera_pose.

注意

Cameras with hypercentric lenses are not supported. For displaying large faces (or primitives) with a non-zero distortion in CameraParamCameraParamCameraParamCameraParamcameraParamcamera_param, note that the distortion is only applied to the points of the model. In the projection, these points are subsequently connected by straight lines. For a good approximation of the distorted lines, please use a triangulation with sufficiently small triangles.
