看源码只有
export class GFXBufferTextureCopy {
public buffOffset: number = 0;
public buffStride: number = 0;
public buffTexHeight: number = 0;
public texOffset: IGFXOffset = { x: 0, y: 0, z: 0 };
public texExtent: IGFXExtent = { width: 0, height: 0, depth: 0 };
public texSubres: GFXTextureSubres = new GFXTextureSubres();
}
