Enumeration Type Documentation

◆ ProjectMode

enum class ProjectMode

strong

Main projection mode.

Enumerator
CLOSEST_VERTEX	Deprecated Use ClosestVertex instead.
CLOSEST_POINT	Deprecated Use ClosestPoint instead.
RAY_CASTING	Deprecated Use RayCasting instead.
ClosestVertex	Copy attribute from the closest vertex on the source mesh.
ClosestPoint	Interpolate attribute from the closest point on the source mesh.
RayCasting	Copy attribute by projecting along a prescribed direction on the source mesh.

◆ CastMode

enum class CastMode

strong

Ray-casting mode.

Enumerator
ONE_WAY	Deprecated Use OneWay instead.
BOTH_WAYS	Deprecated Use BothWays instead.
OneWay	Cast a ray forward in the prescribed direction.
BothWays	Cast a ray both forward and backward in the prescribed direction.

◆ FallbackMode

enum class FallbackMode

strong

Fallback mode for vertices without a hit.

Enumerator
CONSTANT	Deprecated Use Constant instead.
CLOSEST_VERTEX	Deprecated Use ClosestVertex instead.
CLOSEST_POINT	Deprecated Use ClosestPoint instead.
Constant	Fill with a constant value (defaults to 0).
ClosestVertex	Copy attribute from the closest vertex on the source mesh.
ClosestPoint	Interpolate attribute from the closest point on the source mesh.

◆ SceneFlags

enum class SceneFlags

strong

Flags for configuring the ray caster and the underlying Embree scene.

These flags are passed to the RayCaster constructor and control how the BVH is built and traversed.

Enumerator
None	No special behavior.
Dynamic	Indicates that the scene will be updated frequently.
Compact	Use a more compact BVH layout that may be faster to build but slower to traverse.
Robust	Use a more robust BVH traversal algorithm that is slower but less likely to miss hits due to numerical issues.
Filter	Enable user-defined intersection and occlusion filters.

◆ BuildQuality

enum class BuildQuality

strong

Quality levels for BVH construction.

Higher quality typically results in faster ray queries but longer build times.

Enumerator
Low	Fastest build time, lowest BVH quality.
Medium	Moderate build time and BVH quality.
High	Slowest build time, highest BVH quality.
