}Expand description
Represents a viewer, usually some kind of camera. The default implementation of this trait is the Camera which should be adequate for most use cases.
Required Methods§
Sourcefn projection(&self) -> Mat4
fn projection(&self) -> Mat4
The projection matrix which transforms from view space to clip space (2D position on the screen).
Sourcefn color_mapping(&self) -> ColorMapping
fn color_mapping(&self) -> ColorMapping
Defines the ColorMapping applied to the final rendered image.
Sourcefn tone_mapping(&self) -> ToneMapping
fn tone_mapping(&self) -> ToneMapping
Defines the ToneMapping applied to the final rendered image.
