`Geometry`

인터페이스, 런타임 분류

What a draw draws: count vertices, instances times, from the vertex buffer the manifest lays out.

import type { Geometry } from 'typeshade/runtime'

구문

interface Geometry {
  readonly count: number;
  readonly instances?: number;
  readonly vertices?: ArrayBufferView | object;
  readonly indices?: Uint16Array | Uint32Array | { readonly buffer: object; readonly format: 'uint16' | 'uint32' };
}

설명

A typed array is uploaded at the draw; a GPUBuffer is bound as is.

인스턴스 속성

count읽기 전용 number: How many vertices, or indices when indices is given.
instances선택 사항읽기 전용 number: How many instances: 1 when omitted.
vertices선택 사항읽기 전용 ArrayBufferView | object: The vertex buffer, laid out as the manifest’s vertex entry reads it (its @location inputs, tightly packed): a typed array, uploaded at each draw, or the host’s GPUBuffer. Omitted for a vertex entry with no @location input, such as a full-screen triangle drawn from vertex_index.
indices선택 사항읽기 전용 Uint16Array | Uint32Array | { readonly buffer: object; readonly format: 'uint16' | 'uint32' }: The index buffer: a Uint16Array or Uint32Array, uploaded at each draw, or { buffer, format }, the host’s GPUBuffer bound as it is.
