trait for 4x4 projection matrices

Required Methods

fn get_frustum_planes(&self) -> [Vec4<T>; 6]

returns 6 frustum planes as Vec4’s in the form .xyz = normal, .w = plane distance

fn get_frustum_corners(&self) -> [Vec3<T>; 8]

returns 8 points which are the corners of the frustum first 4 near, second 4 far

fn create_ortho_matrix( left: T, right: T, bottom: T, top: T, near: T, far: T, ) -> Self

returns an orthogrpahic projection matrix defined by left, right, top, bottom edges and near - far depth range

fn create_perspective_projection_lh_yup( fov: T, aspect: T, near: T, far: T, ) -> Self

returns a perespective projection matrix (left hand coordinate system with y-up) from fov (radians), aspect ratio and near - far depth

fn create_perspective_projection_rh_yup( fov: T, aspect: T, near: T, far: T, ) -> Self

returns a perespective projection matrix (right hand coordinate system with y-up) from fov (radians), aspect ratio and near - far depth

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
