Struct SubCameraView

pub struct SubCameraView {
    pub full_size: UVec2,
    pub offset: Vec2,
    pub size: UVec2,
}

Settings to define a camera sub view.

When Camera::sub_camera_view is Some, only the sub-section of the image defined by size and offset (relative to the full_size of the whole image) is projected to the cameras viewport.

Take the example of the following multi-monitor setup:

┌───┬───┐
│ A │ B │
├───┼───┤
│ C │ D │
└───┴───┘

If each monitor is 1920x1080, the whole image will have a resolution of 3840x2160. For each monitor we can use a single camera with a viewport of the same size as the monitor it corresponds to. To ensure that the image is cohesive, we can use a different sub view on each camera:

• Camera A: full_size = 3840x2160, size = 1920x1080, offset = 0,0
• Camera B: full_size = 3840x2160, size = 1920x1080, offset = 1920,0
• Camera C: full_size = 3840x2160, size = 1920x1080, offset = 0,1080
• Camera D: full_size = 3840x2160, size = 1920x1080, offset = 1920,1080

However since only the ratio between the values is important, they could all be divided by 120 and still produce the same image. Camera D would for example have the following values: full_size = 32x18, size = 16x9, offset = 16,9

Fields

full_size: UVec2

Size of the entire camera view

offset: Vec2

Offset of the sub camera

size: UVec2

Size of the sub camera
