GLInstancedBufferAttribute
Defined in: core/utils/GLInstancedBufferAttribute.ts:8
A class that extends GLBufferAttribute to handle instanced buffer attributes.
This class was specifically created to allow updating instanced buffer attributes during the onBeforeRender callback,
providing an efficient way to modify the buffer data dynamically before rendering.

Constructors
new GLInstancedBufferAttribute()
new GLInstancedBufferAttribute(
gl,type,itemSize,elementSize,array,meshPerAttribute):GLInstancedBufferAttribute
Defined in: core/utils/GLInstancedBufferAttribute.ts:35
Parameters
gl
WebGL2RenderingContext
The WebGL2RenderingContext used to create the buffer.
type
number
The type of data in the attribute.
itemSize
number
The number of elements per attribute.
elementSize
The size of individual elements in the array.
1 | 2 | 4
array
TypedArray
The data array that holds the attribute values.
meshPerAttribute
number = 1
The number of meshes that share the same attribute data.
Returns
Overrides
GLBufferAttribute.constructor
Properties
array
array:
TypedArray
Defined in: core/utils/GLInstancedBufferAttribute.ts:20
The data array that holds the attribute values.
isGLInstancedBufferAttribute
isGLInstancedBufferAttribute:
boolean=true
Defined in: core/utils/GLInstancedBufferAttribute.ts:12
Indicates if this is an isGLInstancedBufferAttribute.
meshPerAttribute
meshPerAttribute:
number
Defined in: core/utils/GLInstancedBufferAttribute.ts:16
The number of meshes that share the same attribute data.
Methods
update()
update(
renderer,count):void
Defined in: core/utils/GLInstancedBufferAttribute.ts:54
Updates the buffer data.
This method is designed to be called during the onBeforeRender callback.
It ensures that the attribute data is updated just before the rendering process begins.
Parameters
renderer
WebGLRenderer
The WebGLRenderer used to render the scene.
count
number
The number of elements to update in the buffer.
Returns
void
