Enum dae_parser::WrapMode

pub enum WrapMode {
    Wrap,
    Mirror,
    Clamp,
    Border,
    None,
}

Wrap modes that affect the interpretation of s, t, and p texture coordinates in Sampler* elements.

Variants

Wrap

OpenGL symbol GL_REPEAT. Ignores the integer part of texture coordinates, using only the fractional part.

Mirror

OpenGL symbol GL_MIRRORED_REPEAT. First mirrors the texture coordinate. The mirrored coordinate is then clamped as described for Clamp.

Clamp

OpenGL symbol GL_CLAMP_TO_EDGE. Clamps texture coordinates at all mipmap levels such that the texture filter never samples a border texel. Note: GL_CLAMP takes any texels beyond the sampling border and substitutes those texels with the border color. So CLAMP_TO_EDGE is more appropriate. This also works much better with OpenGL ES where the GL_CLAMP symbol was removed from the OpenGL ES specification.

Border

OpenGL symbol GL_CLAMP_TO_BORDER. Clamps texture coordinates at all MIPmaps such that the texture filter always samples border texels for fragments whose corresponding texture coordinate is sufficiently far outside the range [0, 1].

None

The defined behavior for None is consistent with decal texturing where the border is black. Mapping this calculation to GL_CLAMP_TO_BORDER is the best approximation of this.

Implementations

impl WrapMode

pub fn to_str(self) -> &'static str

The XML name of a value in this enumeration.

Trait Implementations

impl Clone for WrapMode

fn clone(&self) -> WrapMode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for WrapMode

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

Formats the value using the given formatter.

impl Default for WrapMode

fn default() -> Self

Returns the “default value” for a type.

impl Display for WrapMode

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

Formats the value using the given formatter.

impl FromStr for WrapMode

type Err = ()

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl PartialEq<WrapMode> for WrapMode

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

This method tests for self and other values to be equal, and is used by ==.

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

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