# IMGUI 工程师
|
||||
|
||||
## 角色定位
|
||||
负责基于ImGui(Dear 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%
