👑 DESCRIPTION 👑

A perspective camera defines a perspective projection from a viewpoint. that's the whole point bestie 💅 The viewing volume for a perspective camera is a truncated right pyramid — yes, like a pyramid with the top chopped off, no cap 🏔️

By default, the camera is located at (0,0,1) and looks along the negative z-axis; the position and orientation fields can be used to change these values. The heightAngle field defines the total vertical angle of the viewing volume; this and the aspectRatio field determine the horizontal angle. 🦋

---

🎀 FIELDS 🎀

• SoSFFloat heightAngle — Vertical angle of the viewing volume. the main character field fr fr 😭

---

🌈 METHODS 🌈

• SoPerspectiveCamera() — Creates a perspective camera node with default settings. fresh out the box, no notes ✨
• static SoType getClassTypeId() — Returns type identifier for this class. it's giving ✨credentials✨

---

🔥 ACTION BEHAVIOR 🔥

SoGLRenderAction, SoCallbackAction, SoGetBoundingBoxAction, SoHandleEventAction, SoRayPickAction

Sets the viewport and camera information in the state. 🫶

---

💜 FILE FORMAT/DEFAULTS 💜

PerspectiveCamera {
     viewportMapping  ADJUST_CAMERA
     position         0 0 1
     orientation      0 0 1  0
     aspectRatio      1
     nearDistance     1
     farDistance      10
     focalDistance    5
     heightAngle      0.785398
}

look at those defaults. pristine. untouched. a whole aesthetic 🌸

okay that's the whole page, you ate that, and just so you know — this was SoPerspectiveCamera(3IV)(), the version/source tag and date footer, lovingly preserved in this little sign-off because the facts don't change even when the vibe does. bye bestie, go render something gorgeous 🎀💖✨
