Implementations§

Source§

impl Camera

Source

pub fn new(aspect_ratio: f32) -> Camera

Source

pub fn set_position(&mut self, pos: Point3<f32>)

Source

pub fn set_fovy(&mut self, fovy: f32)

Source

pub fn set_near(&mut self, near: f32)

Source

pub fn set_far(&mut self, far: f32)

Source

pub fn set_near_far(&mut self, near: f32, far: f32)

Set both near and far planes (for better Z-buffer precision)

Important: Keep the near/far ratio as small as possible to reduce Z-fighting. A ratio of 20:1 or less is recommended. For example:

  • Small scene (0.5-10 units): near=0.5, far=10.0 (20:1)
  • Medium scene (1-15 units): near=1.0, far=15.0 (15:1)
  • Large scene (2-20 units): near=2.0, far=20.0 (10:1)

See ZBUFFER_TUNING.md for detailed guidance.

Source

pub fn get_near_far_ratio(&self) -> f32

Get the current near/far ratio (lower is better for Z-buffer precision)

Source

pub fn set_target(&mut self, target: Point3<f32>)

Source

pub fn get_direction(&self) -> Vector3<f32>

Source

pub fn get_aspect_ratio(&self) -> f32
