Enum re_renderer::view_builder::OrthographicCameraMode

pub enum OrthographicCameraMode {
    NearPlaneCenter,
    TopLeftCornerAndExtendZ,
}

Configures the camera placement in the orthographic frustum, as well as the coordinate system convention.

Variants

NearPlaneCenter

Puts the view space origin into the middle of the screen.

Near plane is at z==0, everything with view space z>0 is clipped.

This is best for regular 3D content.

Uses RUB (X=Right, Y=Up, Z=Back)

TopLeftCornerAndExtendZ

Puts the view space origin at the top-left corner of the orthographic frustum and inverts the y axis, such that the bottom-right corner is at glam::vec3(vertical_world_size * aspect_ratio, vertical_world_size, 0.0) in view space.

Near plane is at z==-far_plane_distance, allowing the same z range both negative and positive.

This means that for an identity camera, world coordinates map directly to pixel coordinates (if Projection::Orthographic::vertical_world_size is set to the y resolution). Best for pure 2D content.

Uses RDF (X=Right, Y=Down, Z=Forward)
