+# RHIBuffer::SetData
+
+```cpp
+virtual void SetData(const void* data, size_t size, size_t offset = 0) = 0;
+```
+
+设置缓冲区数据。
+
+**参数：**
+- `data` - 源数据指针
+- `size` - 数据大小（字节）
+- `offset` - 缓冲区内的偏移量
+
+**复杂度：** O(n)
+
+**示例：**
+
+```cpp
+Vertex vertices[] = {
+    {0.0f, 0.5f, 0.0f},
+    {0.5f, -0.5f, 0.0f},
+    {-0.5f, -0.5f, 0.0f}
+};
+buffer->SetData(vertices, sizeof(vertices), 0);
+```
