Struct PrespectiveCamera 

pub struct PrespectiveCamera { /* private fields */ }

Implementation of camera for Prespective Camera

Example

use cgmath::point3;
use steamengine_renderer_util::camera::create_bindings;
use steamengine_renderer_util::camera::CameraBuffer;

let camera = PrespectiveCamera::default();
// set the aspect ratio with window properties
*camera.aspect_ratio() = width / height;
// sets the camera location
*camera.eye() = point3(0.0, 0.0, -2.0);

// upload the camera to the shader
let buffer = CameraBuffer::new(&renderer, 1);
let binding = create_bindings(&renderer, buffer.as_entrie());

buffer.set(0, camera);
