# OpenGLTexture::Initialize2D
|
|||
|
|
|
|||
|
|
```cpp
|
|||
|
|
bool Initialize2D(int width, int height, int channels, const void* data, bool generateMipmap = true)
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
初始化一个 2D 纹理。
|
|||
|
|
|
|||
|
|
**参数：**
|
|||
|
|
- `width` - 纹理宽度（像素）
|
|||
|
|
- `height` - 纹理高度（像素）
|
|||
|
|
- `channels` - 通道数（1=R, 2=RG, 4=RGBA）
|
|||
|
|
- `data` - 纹理数据指针（可以为 nullptr 创建空纹理）
|
|||
|
|
- `generateMipmap` - 是否自动生成 mipmap（默认为 true）
|
|||
|
|
|
|||
|
|
**返回：** `bool` - 成功返回 true，失败返回 false
|
|||
|
|
|
|||

|
**示例：**
|
|||
|
|
|
|||
|
|
```cpp
|
|||
|
|
OpenGLTexture texture;
|
|||
|
|
std::vector<unsigned char> pixels(width * height * 4);
|
|||
|
|
texture.Initialize2D(width, height, 4, pixels.data(), true);
|
|||
|
|
```
