camera3D
Canonical ID: scene3d.camera. Nederlands: camera3D.
Sets the camera to an absolute world position and preserves yaw (the left-or-right angle) and pitch (the up-or-down angle). Placement is explicit and can place the camera inside an object; it does not run movement collision checks. The initial camera is (0,1.5,5), facing -Z. Use lookAt3D afterward when you want it to point at a particular world target.
See 3D words and camera rules.

Notes and common mistakes
Use the function name for your source language. Its canonical ID is a shared documentation label; you do not type that ID as a call. Giving your own variable or function the same name can hide the built-in. Supply the documented arguments and value types. Pliro reports mismatches when checking can detect them, or when the call runs.
A host is the app or environment running your program. To see a drawing, it needs a renderer, the part that draws on screen. The command-line command pliro run shows text but does not draw these graphics. The host support table explains which effects work in the IDE, browser, native app, and phone preview. A native build reports an unsupported capability instead of leaving it out.
In 3D, +Y points up. Yaw is the left-or-right angle; at zero the camera faces -Z. The world holds at most 256 objects. Changes appear when you call draw3D. An invalid call leaves the world unchanged. Editing requires an existing object name; creating objects and removing an absent name are exceptions. Use the portable color names or hex codes; transparent colors are unavailable here. Version 1 of the phone preview’s communication format does not carry 3D scenes. See the 3D guide for the coordinate rules.
