Expand description

How we project from 3D to 2D.

Variants§

§

Perspective

Perspective camera looking along the negative z view space axis.

Fields

§vertical_fov: f32

Viewing angle in view space y direction (which is the vertical screen axis) in radian.

§near_plane_distance: f32

Distance of the near plane.

§aspect_ratio: f32

Aspect ratio of the perspective transformation.

This is typically just resolution.y / resolution.x. Setting this to anything else is mostly useful when panning & zooming within a fixed transformation.

§

Orthographic

Orthographic projection with the camera position at the near plane’s center, looking along the negative z view space axis.

Fields

§camera_mode: OrthographicCameraMode
§vertical_world_size: f32

Size of the orthographic camera view space y direction (which is the vertical screen axis).

§far_plane_distance: f32

Distance of the far plane to the camera.
