VertexBuffer class final

Describes one vertex buffer slot: its per-element stride, step mode, and the attributes that are read from it.

A buffer's position in VertexLayout.buffers determines the binding slot it is bound to via RenderPass.bindVertexBuffer; the first buffer is slot 0, the second is slot 1, and so on. Sparse binding slots are not currently supported.

The stepMode determines whether the buffer advances once per vertex or once per instance. Keep the default VertexStepMode.vertex for mesh data that describes the geometry being repeated. Use VertexStepMode.instance for data that changes from one instance to the next when calling RenderPass.draw or RenderPass.drawIndexed with an instanceCount greater than 1.

Constructors

VertexBuffer({required int strideInBytes, required List<VertexAttribute> attributes, VertexStepMode stepMode = VertexStepMode.vertex})
Creates a vertex buffer slot description with the given per-element strideInBytes and the list of attributes that the vertex shader reads from this buffer.

Properties

attributes → List<VertexAttribute>
Attributes read from this vertex buffer by the vertex shader.
final
hashCode → int
The hash code for this object.
no setterinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
stepMode → VertexStepMode
How this vertex buffer advances while drawing.
final
strideInBytes → int
Byte distance from the start of one element to the start of the next element in this vertex buffer (not the gap between an element's end and the next element's start). Equivalent to the size of a single vertex element plus any trailing padding before the next element begins. For a tightly packed structure-of-arrays buffer carrying a single attribute, this is the same as attributes[0].format.bytesPerElement.
