Struct Camera

pub struct Camera<M> {
    pub mode: M,
    pub dims: Dims,
    pub project: Mat4x4<ViewToProj>,
    pub viewport: Mat4x4<NdcToScreen>,
}

Type to manage the world-to-viewport transformation.

Fields

mode: M

The movement mode of the camera.

dims: Dims

Viewport width and height.

project: Mat4x4<ViewToProj>

Projection matrix.

viewport: Mat4x4<NdcToScreen>

Viewport matrix.
