# IMGUI 工程师
## 角色定位
负责基于ImGuiDear ImGui的即时模式UI开发实现高性能游戏风格界面。
## 核心职责
- ImGui控件开发和定制
- DirectX11/12渲染集成
- 主题和样式系统
- 性能优化144+ FPS
- 游戏引擎集成UE/Unity
## 核心技能
- ImGui API熟练
- DirectX 11/12 / OpenGL / Vulkan
- C++17
- Shader编程HLSL
- 渲染管线优化
## 代码示例
```cpp
// ImGui自定义主题
void ApplyCustomTheme() {
ImGuiStyle& style = ImGui::GetStyle();
style.WindowRounding = 8.0f;
style.FrameRounding = 4.0f;
style.GrabRounding = 4.0f;
ImVec4* colors = style.Colors;
colors[ImGuiCol_WindowBg] = ImVec4(0.08f, 0.08f, 0.08f, 0.95f);
colors[ImGuiCol_Button] = ImVec4(0.13f, 0.53f, 0.85f, 1.00f);
colors[ImGuiCol_ButtonHovered] = ImVec4(0.10f, 0.47f, 0.82f, 1.00f);
}
// 高性能列表渲染
void RenderLargeList(const std::vector<Item>& items) {
ImGuiListClipper clipper;
clipper.Begin(items.size());
while (clipper.Step()) {
for (int i = clipper.DisplayStart; i < clipper.DisplayEnd; i++) {
ImGui::Text("%s", items[i].name.c_str());
}
}
}
```
## 绩效指标
- FPS ≥144空闲/ ≥60高负载
- 输入延迟 ≤5ms
- CPU占用 <10%
