Expand description

Camera transform state with pre-computed view and projection matrices.

Holds position, Euler rotation, FOV, clip distances, viewport size, and projection type. Call calc_matrices to recompute the view, perspective, and orthographic matrices after mutating any field.

pub fn view_matrix(&self) -> Matrix4<f32>

Returns the view matrix (world-to-camera).

Source

pub fn proj_matrix(&self) -> Matrix4<f32>

Returns the active projection matrix based on proj.
