Enumerations: aspose.threed.entities (aspose-3d-foss)

Camera adalah satu Entity yang mendefinisikan sudut pandang dalam adegan 3D. Ia mengawal bagaimana adegan diproyeksikan ke atas satah imej 2D. Kamera dipasang pada Node untuk menempatkan dan mengorientasikannya dalam adegan.

Nota Pelaksanaan

Dalam edisi aspose-3d-foss ini, Camera kelas ialah satu stub deklarasi. Hanya projection_type dan name disimpan secara fungsional dan boleh diambil semula. Semua sifat lain (near_plane, far_plane, field_of_view, aspect_ratio, dll.) mempunyai setter yang tidak berfungsi; nilai yang diberikan tidak disimpan. Membaca semula sifat-sifat ini mengembalikan nilai lalai kelas tanpa mengira apa yang telah ditetapkan.

Apabila mengimport data kamera daripada fail 3D (glTF, FBX), projection_type diparse dengan betul. Atribut kamera lain tersedia jika format menyimpannya sebagai metadata graf-adegan.

Enumerations

SignatureDescription
__init__(name: str, projection_type)
move_forward(distance: float)Moves the camera forward by the specified distance
get_bounding_box()Returns the bounding box.
get_entity_renderer_key()Not implemented in the FOSS edition — throws at runtime. Returns the entity renderer key.
remove_property(property)Removes a custom property identified by the given property object
remove_property(property_name: str)
get_property(property: str)Retrieves the value of a custom property by its identifier
set_property(property: str, value)Sets the property value.
find_property(property: str)Searches for a custom property and returns it if found

Contoh Penggunaan

Enumerations: Dalam edisi ini, hanya projection_type disimpan secara fungsional. Penetapan sifat untuk near_plane, far_plane, field_of_view, dan aspect_ratio diterima tanpa ralat tetapi tidak berterusan.

Kamera Perspektif 

from aspose.threed import Scene
from aspose.threed.entities import Camera
from aspose.threed.entities import ProjectionType

scene = Scene()

# projection_type is stored and saved
cam = Camera("MainCamera", ProjectionType.PERSPECTIVE)

node = scene.root_node.create_child_node("camera", cam)

# Position the camera using node transform (this does persist)
node.transform.set_translation(0.0, 5.0, 20.0)

scene.save("scene-with-camera.glb")

Kamera Ortografik 

from aspose.threed import Scene, FileFormat
from aspose.threed.entities import Camera, ProjectionType

scene = Scene()

# Only projection_type is retained; other property assignments are no-ops
cam = Camera("OrthoCamera", ProjectionType.ORTHOGRAPHIC)

scene.root_node.create_child_node("ortho_cam", cam)
scene.save("ortho-scene.glb", FileFormat.GLTF)

Baca Kamera Selepas Import 

from aspose.threed import Scene
from aspose.threed.entities import Camera

scene = Scene()
scene.open("model.glb")

for node in scene.root_node.child_nodes:
    if isinstance(node.entity, Camera):
        cam = node.entity
        # projection_type is reliably populated; other numeric properties
        # return default values (0.0 / 1.0) regardless of file content
        print(f"Camera '{cam.name}': {cam.projection_type}")
