Define a ggWebGL View Contract — ggwebgl

Build a structured renderer view specification. This replaces the previous loose dimension, camera, projection, and camera_state fields while keeping them mirrored internally for older renderer paths.

Usage

ggwebgl_view(
  dimension = c("2d", "3d"),
  projection = c("orthographic", "perspective"),
  controller = NULL,
  state = list()
)

Arguments

dimension: Renderer dimensionality, "2d" or "3d".
projection: Projection mode, "orthographic" or "perspective".
controller: Interaction controller. Use "panzoom" for 2D scenes and "orbit" or "trackball" for 3D scenes.
state: Camera/view state list. Recognized fields include target, distance, rotation, up, fov, near, and far. Legacy yaw and pitch are converted to rotation.

Value

A ggwebgl_view list.
