Enum TexSampleComp 

#[repr(u32)]
pub enum TexSampleComp {
    None = 0,
    Less = 1,
    LessOrEq = 2,
    Greater = 3,
    GreaterOrEq = 4,
    Equal = 5,
    NotEqual = 6,

    Never = 8,
}

How does the GPU compare sampled values against existing texture data? This is mostly useful for depth textures where the hardware can do a comparison (ex: shadow map lookups) as part of the sampling operation. Default is None, which means no comparison test is performed. These map directly to the native tex_sample_comp_ values. https://stereokit.net/Pages/StereoKit/TexSampleComp.html

Variants

None = 0

No comparison test; returns the raw sampled value.

Less = 1

Passes if sampled value is less than the reference.

LessOrEq = 2

Passes if sampled value is less than or equal to the reference.

Greater = 3

Passes if sampled value is greater than the reference.

GreaterOrEq = 4

Passes if sampled value is greater than or equal to the reference.

Equal = 5

Passes if sampled value equals the reference.

NotEqual = 6

Passes if sampled value does not equal the reference.

Always = 7

Always passes (effectively disables depth based rejection, but still channels through comparison hardware).

Never = 8

Never passes.

Trait Implementations

impl Clone for TexSampleComp

fn clone(&self) -> TexSampleComp

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TexSampleComp

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

Formats the value using the given formatter.

impl PartialEq for TexSampleComp

fn eq(&self, other: &TexSampleComp) -> 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.
