Camera3D (Mibo)

Camera3D Module

Namespace: Mibo.Elmish
Assembly: Mibo.Raylib.dll

Helper functions for 3D Cameras (Perspective / Orthographic projection).

Use these for first-person, third-person, or any 3D game rendering.

The raylib Camera3D is a native mutable struct. screenPointToRay takes it by inref (use &camera); the config builders take it by value; the constructors (create/orbit) and modifiers (withUp/asOrthographic) return a new Camera3D.

Functions and values

Function or value	Description
`asOrthographic camera` Full Usage: `asOrthographic camera` Parameters: camera : `Camera3D` Returns: `Camera3D` Modifiers: inline	Switch the camera to orthographic projection. `FovY` is reinterpreted as the vertical view size in world units. camera : `Camera3D` Returns: `Camera3D`
`create position target fovy` Full Usage: `create position target fovy` Parameters: position : `Vector3` - Camera position in world space. target : `Vector3` - Point the camera is looking at. fovy : `float32` - Vertical field of view in degrees. Returns: `Camera3D` Modifiers: inline	Creates a perspective `Camera3D` that looks at a target from a position. Mirrors the MonoGame `Camera3D.create` capability, but returns the native raylib `Camera3D` struct. The field-of-view is in degrees (raylib convention), unlike MonoGame's radians. Near/far planes and aspect ratio are managed internally by raylib's `BeginMode3D`, so they are not parameters here. Up defaults to `Vector3.UnitY`; override with Camera3D.withUp. position : `Vector3` Camera position in world space. target : `Vector3` Point the camera is looking at. fovy : `float32` Vertical field of view in degrees. Returns: `Camera3D`
`orbit target yaw pitch radius fovy` Full Usage: `orbit target yaw pitch radius fovy` Parameters: target : `Vector3` - Point the camera orbits around. yaw : `float32` - Horizontal rotation angle in radians. pitch : `float32` - Vertical rotation angle in radians. radius : `float32` - Distance from target. fovy : `float32` - Vertical field of view in degrees. Returns: `Camera3D` Modifiers: inline	Creates an orbiting perspective `Camera3D` using spherical coordinates. Useful for third-person cameras, inspection views, or editor cameras. The field-of-view is in degrees (raylib convention). target : `Vector3` Point the camera orbits around. yaw : `float32` Horizontal rotation angle in radians. pitch : `float32` Vertical rotation angle in radians. radius : `float32` Distance from target. fovy : `float32` Vertical field of view in degrees. Returns: `Camera3D`
`render camera` Full Usage: `render camera` Parameters: camera : `Camera3D` Returns: `Camera3DConfig` Modifiers: inline	Create a rendering config from a raylib camera. Defaults: fullscreen, no clear. camera : `Camera3D` Returns: `Camera3DConfig`
`screenPointToRay camera screenPos` Full Usage: `screenPointToRay camera screenPos` Parameters: camera : `inref<Camera3D>` - Passed by read-only reference (`&camera`) to avoid copying the native struct. screenPos : `Vector2` - The screen position in pixels. Returns: `Ray` Modifiers: inline	Creates a ray from screen coordinates for mouse/touch picking. Thin wrapper over raylib's native `Raylib.GetScreenToWorldRay`, returning the native `Raylib_cs.Ray` so it composes with raylib's own picking/collision helpers. Mirrors the MonoGame `Camera3D.screenPointToRay` capability. camera : `inref<Camera3D>` Passed by read-only reference (`&camera`) to avoid copying the native struct. screenPos : `Vector2` The screen position in pixels. Returns: `Ray`
`splitScreenBottom camera clearColor` Full Usage: `splitScreenBottom camera clearColor` Parameters: camera : `Camera3D` clearColor : `Color` Returns: `Camera3DConfig` Modifiers: inline	Split-screen bottom half. Clears with given color. camera : `Camera3D` clearColor : `Color` Returns: `Camera3DConfig`
`splitScreenLeft camera clearColor` Full Usage: `splitScreenLeft camera clearColor` Parameters: camera : `Camera3D` clearColor : `Color` Returns: `Camera3DConfig` Modifiers: inline	Split-screen left half. Clears with given color. camera : `Camera3D` clearColor : `Color` Returns: `Camera3DConfig`
`splitScreenRight camera clearColor` Full Usage: `splitScreenRight camera clearColor` Parameters: camera : `Camera3D` clearColor : `Color` Returns: `Camera3DConfig` Modifiers: inline	Split-screen right half. Clears with given color. camera : `Camera3D` clearColor : `Color` Returns: `Camera3DConfig`
`splitScreenTop camera clearColor` Full Usage: `splitScreenTop camera clearColor` Parameters: camera : `Camera3D` clearColor : `Color` Returns: `Camera3DConfig` Modifiers: inline	Split-screen top half. Clears with given color. camera : `Camera3D` clearColor : `Color` Returns: `Camera3DConfig`
`withClear color config` Full Usage: `withClear color config` Parameters: color : `Color` config : `Camera3DConfig` Returns: `Camera3DConfig` Modifiers: inline	Clear with this color before rendering. color : `Color` config : `Camera3DConfig` Returns: `Camera3DConfig`
`withUp up camera` Full Usage: `withUp up camera` Parameters: up : `Vector3` camera : `Camera3D` Returns: `Camera3D` Modifiers: inline	Set the up vector (default is `Vector3.UnitY`). up : `Vector3` camera : `Camera3D` Returns: `Camera3D`
`withViewport viewport config` Full Usage: `withViewport viewport config` Parameters: viewport : `Rectangle` config : `Camera3DConfig` Returns: `Camera3DConfig` Modifiers: inline	Set viewport in normalized screen coordinates (0-1). viewport : `Rectangle` config : `Camera3DConfig` Returns: `Camera3DConfig`
