Camera

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

Camera je Entity koji definiše tačku gledišta u 3D sceni. Kontroliše kako se scena projicira na 2D ravninu slike. Kamera je pričvršćena na Node da je pozicionira i orijentiše u sceni.

class Camera(Entity):

Example

A3DObject → SceneObject → Entity → Camera

Napomene o implementaciji

U ovoj verziji aspose-3d-foss, Camera klasa je šablon deklaracije. Samo projection_type i name su funkcionalno pohranjene i dostupne. Sva ostala svojstva (near_plane, far_plane, field_of_view, aspect_ratio, itd.) imaju setere koji ne rade ništa; dodeljene vrednosti se ne čuvaju. Prilikom čitanja ovih svojstava vraća se podrazumevana vrednost klase, bez obzira na to šta je dodeljeno.

Pri uvozu podataka kamere iz 3D fajla (glTF, FBX), projection_type se pravilno parsira. Ostali atributi kamere su dostupni ako format čuva ih kao scene-graph metapodatke.

Example 

Camera(name: str = None, projection_type: str = "PERSPECTIVE")

Example

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

Primeri upotrebe

Example: U ovom izdanju, samo projection_type se funkcionalno čuva. Dodeljivanja svojstava za near_plane, far_plane, field_of_view, i aspect_ratio se prihvataju bez greške, ali se ne čuvaju.

Perspective Camera 

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")

Orthographic Camera 

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)

Čitanje Camera nakon uvoza 

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}")
