BVH — OpenCascade.js

DynamicType(): Standard_Type
MaxTreeDepth(): number
Returns the maximum depth of constructed BVH.
LeafNodeSize(): number
Returns the maximum number of sub-elements in the leaf.
IsParallel(): boolean
Returns parallel flag.
SetParallel(isParallel: boolean): void
Set parallel flag controlling possibility of parallel execution.
Parameters (1)
- isParallel

BVH_BuildQueue

Command-queue for parallel building of BVH nodes.

Constructors(1)

constructor(): BVH_BuildQueue
Creates new BVH build queue.

Instance methods(4)

Size(): number
Returns current size of BVH build queue. Uses acquire semantics to synchronize with enqueue/dequeue operations.
Enqueue(theWorkItem: number): void
Enqueues new work-item onto BVH build queue.
Parameters (1)
- theWorkItem
Fetch(wasBusy: boolean): { returnValue: number; wasBusy: boolean }
Fetches first work-item from BVH build queue.
Parameters (1)
- wasBusy
Returns
A result object with fields:
- returnValue: the C++ return value
- wasBusy: updated value from the call.
HasBusyThreads(): boolean
Checks if there are active build threads. Uses acquire semantics to ensure visibility of thread counter updates. This is critical for termination detection: threads check this after finding an empty queue to determine if they should exit or wait.

BVH_BuildThread

Standard_Transient

Wrapper for BVH build thread.

Constructors(1)

constructor(theBuildTool: BVH_BuildTool, theBuildQueue: BVH_BuildQueue): BVH_BuildThread
Creates new BVH build thread.
Parameters (2)
- theBuildTool
- theBuildQueue

Static methods(2)

get_type_name(): string
get_type_descriptor(): Standard_Type

Instance methods(3)

Run(): void
Starts execution of BVH build thread.
Wait(): void
Waits till the thread finishes execution.
DynamicType(): Standard_Type

BVH_BuildTool

Tool object to call BVH builder subroutines.

Instance methods(1)

Perform(theNode: number): void
Performs splitting of the given BVH node.
Parameters (1)
- theNode

BVH_ObjectTransient

Standard_Transient

A non-template class for using as base for BVH_Object (just to have a named base class).

Static methods(2)

get_type_name(): string

Instance methods(5)

DynamicType(): Standard_Type
Properties(): BVH_Properties
Returns properties of the geometric object.
SetProperties(theProperties: BVH_Properties): void
Sets properties of the geometric object.
Parameters (1)
- theProperties
IsDirty(): boolean
Returns TRUE if object state should be updated.
MarkDirty(): void
Marks object state as outdated (needs BVH rebuilding).

BVH_Properties

Standard_Transient

Abstract properties of geometric object.

Static methods(2)

get_type_name(): string
get_type_descriptor(): Standard_Type

Instance methods(1)

DynamicType(): Standard_Type

Type corresponding to quad BVH.

Constructors(1)

constructor(): BVH_QuadTree

BVH_RadixSorter

Performs radix sort of a BVH primitive set using 10-bit Morton codes (or 1024 x 1024 x 1024 grid).

Constructors(1)

constructor(): BVH_RadixSorter

BVH_TreeBaseTransient

Standard_Transient

A non-template class for using as base for BVH_TreeBase (just to have a named base class).
