OpenGLCommandList::Clear
void Clear(float r, float g, float b, float a, unsigned int buffers)
清除指定的缓冲区。
参数：
r- 清除颜色红色分量（范围 0.0f - 1.0f）g- 清除颜色绿色分量（范围 0.0f - 1.0f）b- 清除颜色蓝色分量（范围 0.0f - 1.0f）a- 清除颜色 Alpha 分量（范围 0.0f - 1.0f）buffers- 要清除的缓冲区标志，使用ClearFlag枚举值的位或组合：ClearFlag::Color(1) - 清除颜色缓冲区ClearFlag::Depth(2) - 清除深度缓冲区ClearFlag::Stencil(4) - 清除模板缓冲区
返回值：无
示例：
// 清除颜色缓冲区
commandList->Clear(0.0f, 0.0f, 0.0f, 1.0f, static_cast<unsigned int>(ClearFlag::Color));
// 清除颜色和深度缓冲区
commandList->Clear(0.0f, 0.0f, 0.0f, 1.0f,
static_cast<unsigned int>(ClearFlag::Color) |
static_cast<unsigned int>(ClearFlag::Depth));
// 清除所有缓冲区
commandList->Clear(0.0f, 0.0f, 0.0f, 1.0f,
static_cast<unsigned int>(ClearFlag::Color) |
static_cast<unsigned int>(ClearFlag::Depth) |
static_cast<unsigned int>(ClearFlag::Stencil));
