Camera

Methods: com.aspose.threed (aspose-3d-foss 26.1.0)

Camera je Entity ktorý definuje pohľadový bod v 3D scéne. Ovláda, ako je scéna projekčná na 2D rovinu obrazu. Kamera je pripojená k Node na jej umiestnenie a orientáciu v scéne.

Poznámky k implementácii

V edícii Java FOSS, Camera trieda má iba konštruktory — žiadne špecifické vlastnosti kamery (uhol zorného poľa, blízka/vzdialená rovina, režim projekcie) nie sú implementované.

Obmedzenie exportu: Entity kamier sú nepísané pri exporte scén. Exportér glTF (GltfExporter) spracováva iba Mesh entity — uzly kamier sú ticho preskočené. To znamená, že kamera pripojená k uzlu sa neobjaví v žiadnom exportovanom súbore. Príklad „Read Camera After Import“ nižšie ukazuje, ako načítať názvy kamier z importovaného súboru; zapisovanie kamier späť do nového súboru však v tejto edícii nie je podporované.

Príklady použitia

Pripojiť kameru k scéne

import com.aspose.threed.*;

Scene scene = new Scene();

Camera cam = new Camera("MainCamera");

Node node = scene.getRootNode().createChildNode("camera", cam);
node.getTransform().setTranslation(0.0, 5.0, 20.0);

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

Načítať kameru po importe

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

for (Node node : scene.getRootNode().getChildNodes()) {
    if (node.getEntity() instanceof Camera) {
        Camera cam = (Camera) node.getEntity();
