[−][src]Function ultraviolet::projection::rh_yup::perspective_vk
pub fn perspective_vk(
vertical_fov: f32,
aspect_ratio: f32,
z_near: f32,
z_far: f32
) -> Mat4
Perspective projection matrix meant to be used with Vulkan.
vertical_fov
should be provided in radians.aspect_ratio
should be the quotientwidth / height
.
This matrix is meant to be used when the source coordinate space is right-handed and y-up (the standard computer graphics coordinate space) and the destination coordinate space is right-handed and y-down with Z (depth) clip extending from 0.0 (close) to 1.0 (far).
