Expand description

A camera is the lens through which your scene can be viewed. This tells covalent how to map the scene in 2D/3D space onto your screen, a 2D window. The two major types of camera are perspective and orthographic.

Required Methods§

Source

fn get_projection_matrix(&self) -> Matrix4<f32>

Source

fn get_view_matrix(&self) -> Matrix4<f32>

Source

fn get_combined_matrix(&self) -> Matrix4<f32>

Provided Methods§

Source

fn update_matrices(&self, matrices: Arc<RwLock<CameraMatrices>>)

Sends the camera’s matrices to the graphics backend for rendering. Run this function when you’ve edited the camera’s variables e.g. position, view angle, aspect ratio etc.
