Enum Cull 

#[repr(u32)]
pub enum Cull {
    Back = 0,
    Front = 1,
    None = 2,
}

Culling is discarding an object from the render pipeline! This enum describes how mesh faces get discarded on the graphics card. With culling set to none, you can double the number of pixels the GPU ends up drawing, which can have a big impact on performance. None can be appropriate in cases where the mesh is designed to be ‘double sided’. Front can also be helpful when you want to flip a mesh ‘inside-out’! https://stereokit.net/Pages/StereoKit/Cull.html

Variants

Back = 0

Discard if the back of the triangle face is pointing towards the camera. This is the default behavior.

Front = 1

Discard if the front of the triangle face is pointing towards the camera. This is opposite the default behavior.

None = 2

No culling at all! Draw the triangle regardless of which way it’s pointing.

Trait Implementations

impl Clone for Cull

fn clone(&self) -> Cull

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Cull

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Cull

fn eq(&self, other: &Cull) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Cull

impl Eq for Cull

impl StructuralPartialEq for Cull
