|
||
|
|
|
||
|
|
```cpp
|
||
|
|
virtual void SetData(const void* data, size_t size, size_t offset = 0) = 0;
|
||
|
|
```
|
||
|
|
|
||
|
|
设置缓冲区数据。

|
|
- `data` - 源数据指针
|
||
|
|
- `size` - 数据大小（字节）
|
||
|
|
- `offset` - 缓冲区内的偏移量
|
||
|
|
|

```cpp
|
||
|
|
Vertex vertices[] = {
|
||
|
|
{0.0f, 0.5f, 0.0f},
|
||
|
|
{0.5f, -0.5f, 0.0f},
|
||
|
|
{-0.5f, -0.5f, 0.0f}
|
||
|
|
};
