Acceleration structure instance (used by RenderingDevice).

Description

RDAccelerationStructureInstance describes an instance of a Bottom-Level Acceleration Structure (BLAS) used in the RenderingDevice.tlas_build() method.

Properties

RID	blas	RID()
BitField[AccelerationStructureInstanceFlagBits]	flags	0
int	hit_sbt_range	0
int	id	0

Property Descriptions

RID blas = RID() 🔗

• void set_blas(value: RID)

• RID get_blas()

The BLAS referenced by this instance. If null, the instance is treated as a placeholder but still contributes to gl_InstanceIndex in GLSL.

---

BitField[AccelerationStructureInstanceFlagBits] flags = 0 🔗

• void set_flags(value: BitField[AccelerationStructureInstanceFlagBits])

• BitField[AccelerationStructureInstanceFlagBits] get_flags()

Flags for the instance.

---

int hit_sbt_range = 0 🔗

• void set_hit_sbt_range(value: int)

• int get_hit_sbt_range()

Hit shader binding table range used for this instance, allocated using the RenderingDevice.hit_sbt_range_alloc() method.

---

int id = 0 🔗

• void set_id(value: int)

• int get_id()

Custom instance ID that can be accessed in GLSL using gl_InstanceCustomIndexEXT.

---

int mask = 255 🔗

• void set_mask(value: int)

• int get_mask()

Visibility mask used to control which rays can intersect this instance.

---

Transform3D transform = Transform3D(1, 0, 0, 0, 1, 0, 0, 0, 1, 0, 0, 0) 🔗

• void set_transform(value: Transform3D)

• Transform3D get_transform()

Transform applied to the referenced BLAS for this instance.
