Fields

options: MTLAccelerationStructureInstanceOptions

Instance options

mask: u32

Instance mask used to ignore geometry during ray tracing

intersectionFunctionTableOffset: u32

Used to index into intersection function tables

accelerationStructureIndex: u32

Acceleration structure index to use for this instance

userID: u32

User-assigned instance ID to help identify this instance in an application-defined way

motionTransformsStartIndex: u32

The index of the first set of transforms describing one keyframe of the animation. These transforms are stored in a separate buffer and they are uniformly distributed over time time span of the motion.

motionTransformsCount: u32

The count of motion transforms belonging to this motion which are stored in consecutive memory addresses at the separate motionTransforms buffer.

motionStartBorderMode: MTLMotionBorderMode

Motion border mode describing what happens if acceleration structure is sampled before motionStartTime

motionEndBorderMode: MTLMotionBorderMode

Motion border mode describing what happens if acceleration structure is sampled after motionEndTime

motionStartTime: c_float

Motion start time of this instance

motionEndTime: c_float

Motion end time of this instance

Trait Implementations

impl Clone for MTLAccelerationStructureMotionInstanceDescriptor

fn clone(&self) -> MTLAccelerationStructureMotionInstanceDescriptor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MTLAccelerationStructureMotionInstanceDescriptor

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

Formats the value using the given formatter.

impl Encode for MTLAccelerationStructureMotionInstanceDescriptor

const ENCODING: Encoding

The Objective-C type-encoding for this type.

impl PartialEq for MTLAccelerationStructureMotionInstanceDescriptor

fn eq(&self, other: &MTLAccelerationStructureMotionInstanceDescriptor) -> 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 RefEncode for MTLAccelerationStructureMotionInstanceDescriptor

const ENCODING_REF: Encoding

The Objective-C type-encoding for a reference of this type.

impl Copy for MTLAccelerationStructureMotionInstanceDescriptor

impl StructuralPartialEq for MTLAccelerationStructureMotionInstanceDescriptor
