D3D12Texture::InitializeFromData
函数签名
bool InitializeFromData(ID3D12Device* device, ID3D12GraphicsCommandList* commandList,
const void* pixelData, uint32_t width, uint32_t height, DXGI_FORMAT format)
中文描述
从像素数据初始化纹理，内部会创建上传堆并复制数据。
参数
| 参数 | 类型 | 描述 |
|---|---|---|
device |
ID3D12Device* |
D3D12 设备指针 |
commandList |
ID3D12GraphicsCommandList* |
命令列表指针 |
pixelData |
const void* |
像素数据指针 |
width |
uint32_t |
纹理宽度 |
height |
uint32_t |
纹理高度 |
format |
DXGI_FORMAT |
像素格式 |
返回值
bool - 初始化是否成功
复杂度
O(n) - 取决于纹理大小，内部创建临时上传堆
示例
std::vector<uint8_t> pixels = LoadImage("texture.png");
texture->InitializeFromData(device, cmdList, pixels.data(), width, height, DXGI_FORMAT_R8G8B8A8_UNORM);
