Struct usd::pxr::usd_geom::XformCache

#[repr(C, align(8))]
pub struct XformCache { /* private fields */ }

A caching mechanism for transform matrices. For best performance, this object should be reused for multiple CTM queries.

Instances of this type can be copied, though using Swap() may result in better performance.

It is valid to cache prims from multiple stages in a single XformCache.

WARNING

This class does not automatically invalidate cached values based on changes to the stage from which values were cached. Additionally, a separate instance of this class should be used per-thread, calling the Get* methods from multiple threads is not safe, as they mutate internal state.

Implementations

impl XformCache

pub fn new(time: TimeCode) -> XformCache

Methods from Deref<Target = XformCacheRef>

pub fn get_local_to_world_transform(&mut self, prim: &Prim) -> Matrix4d

Compute the transformation matrix for the given \p prim, including the transform authored on the Prim itself, if present.

Note

This method may mutate internal cache state and is not thread safe.

Trait Implementations

impl AsMut<XformCacheRef> for XformCache

fn as_mut(&mut self) -> &mut XformCacheRef

Converts this type into a mutable reference of the (usually inferred) input type.

impl AsRef<XformCacheRef> for XformCache

fn as_ref(&self) -> &XformCacheRef

Converts this type into a shared reference of the (usually inferred) input type.

impl Deref for XformCache

type Target = XformCacheRef

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl DerefMut for XformCache

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl Drop for XformCache

fn drop(&mut self)

Executes the destructor for this type.
