Getting Started

Prerequisites

.NET 9.0 or later

Installation

Package Manager Console

Install-Package ktsu.ImGuiApp

.NET CLI

dotnet add package ktsu.ImGuiApp

Package Reference

<PackageReference Include="ktsu.ImGuiApp" Version="x.y.z" />

Usage Examples

Basic Application

Create a new class and call ImGuiApp.Start() with your application config:

using ktsu.ImGuiApp;
using Hexa.NET.ImGui;

static class Program
{
 static void Main()
 {
 ImGuiApp.Start(new ImGuiAppConfig()
 {
 Title = "ImGuiApp Demo",
 OnStart = () => { /* Initialization code */ },
 OnUpdate = delta => { /* Logic updates */ },
 OnRender = delta => { ImGui.Text("Hello, ImGuiApp!"); },
 OnAppMenu = () =>
 {
 if (ImGui.BeginMenu("File"))
 {
 // Menu items
 if (ImGui.MenuItem("Exit"))
 {
 ImGuiApp.Stop();
 }
 ImGui.EndMenu();
 }
 }
 });
 }
}

Custom Font Management

Use the resource designer to add font files to your project, then load the fonts:

ImGuiApp.Start(new()
{
 Title = "ImGuiApp Demo",
 OnRender = OnRender,
 Fonts = new Dictionary<string, byte[]>
 {
 { nameof(Resources.MY_FONT), Resources.MY_FONT }
 },
});

Or load the font data manually:

var fontData = File.ReadAllBytes("path/to/font.ttf");
ImGuiApp.Start(new()
{
 Title = "ImGuiApp Demo",
 OnRender = OnRender,
 Fonts = new Dictionary<string, byte[]>
 {
 { "MyFont", fontData }
 },
});

Then apply the font to ImGui using the FontAppearance class:

private static void OnRender(float deltaTime)
{
 ImGui.Text("Hello, I am normal text!");

 using (new FontAppearance("MyFont", 24))
 {
 ImGui.Text("Hello, I am BIG fancy text!");
 }

 using (new FontAppearance(32))
 {
 ImGui.Text("Hello, I am just huge text!");
 }

 using (new FontAppearance("MyFont"))
 {
 ImGui.Text("Hello, I am somewhat fancy!");
 }
}

Unicode and Emoji Support

ImGuiApp automatically includes support for Unicode characters and emojis. This feature is enabled by default, so you can use extended characters without any configuration:

private static void OnRender(float deltaTime)
{
 ImGui.Text("Basic ASCII: Hello World!");
 ImGui.Text("Accented characters: café, naïve, résumé");
 ImGui.Text("Mathematical symbols: ∞ ≠ ≈ ≤ ≥ ± × ÷ ∂ ∑");
 ImGui.Text("Currency symbols: $ € £ ¥ ₹ ₿");
 ImGui.Text("Arrows: ← → ↑ ↓ ↔ ↕");
 ImGui.Text("Emojis (if font supports): 😀 🚀 🌟 💻 🎨 🌈");
}

Note: Character display depends on your font's Unicode support. Most modern fonts include extended Latin characters and symbols, but emojis require specialized fonts.

To disable Unicode support (ASCII only), set EnableUnicodeSupport = false:

ImGuiApp.Start(new()
{
 Title = "ASCII Only App",
 EnableUnicodeSupport = false, // Disables Unicode support
 // ... other settings
});

Texture Management

Load and manage textures with the built-in texture management system:

private static void OnRender(float deltaTime)
{
 // Load texture from file path
 var textureInfo = ImGuiApp.GetOrLoadTexture("path/to/texture.png");

 // Use the texture in ImGui (using the new TextureRef API for Hexa.NET.ImGui)
 ImGui.Image(textureInfo.TextureRef, new Vector2(128, 128));

 // Clean up when done (optional - textures are cached and managed automatically)
 ImGuiApp.DeleteTexture(textureInfo);
}

PID Frame Limiting

ImGuiApp features a sophisticated PID (Proportional-Integral-Derivative) controller for precise frame rate limiting. This system provides highly accurate target FPS control that learns and adapts to your system's characteristics.

Key Features

High-Precision Timing: Hybrid sleep system combining Thread.Sleep() for coarse delays with spin-waiting for sub-millisecond accuracy
PID Controller: Advanced control algorithm that learns from frame timing errors and dynamically adjusts sleep times
Comprehensive Auto-Tuning: Multi-phase tuning procedure that automatically finds optimal PID parameters for your system
VSync Independence: Works independently of monitor refresh rates for any target FPS
Real-Time Diagnostics: Built-in performance monitoring and tuning visualization

Optimized Defaults

ImGuiApp comes pre-configured with optimal PID parameters derived from comprehensive auto-tuning:

Kp: 1.800 - Proportional gain for current error response
Ki: 0.048 - Integral gain for accumulated error correction
Kd: 0.237 - Derivative gain for predictive adjustment

These defaults provide excellent frame timing accuracy out-of-the-box for most systems.

Configuration

Configure frame limiting through ImGuiAppPerformanceSettings:

ImGuiApp.Start(new ImGuiAppConfig
{
 Title = "PID Frame Limited App",
 OnRender = OnRender,
 PerformanceSettings = new ImGuiAppPerformanceSettings
 {
 EnableThrottledRendering = true,
 FocusedFps = 30.0, // Target 30 FPS when focused
 UnfocusedFps = 5.0, // Target 5 FPS when unfocused
 IdleFps = 10.0, // Target 10 FPS when idle
 NotVisibleFps = 2.0, // Target 2 FPS when minimized
 EnableIdleDetection = true,
 IdleTimeoutSeconds = 30.0 // Idle after 30 seconds
 }
});

Auto-Tuning Procedure

For maximum accuracy, ImGuiApp includes a comprehensive 3-phase auto-tuning system:

Coarse Phase (8s per test): Tests 24 parameter combinations to find the general optimal range
Fine Phase (12s per test): Tests 25 refined parameters around the best coarse result
Precision Phase (15s per test): Final optimization with 9 precision-focused parameters

Total tuning time: ~12-15 minutes for maximum accuracy

Access auto-tuning through the Debug > Show Performance Monitor menu, which provides:

Real-time tuning progress visualization
Performance metrics (Average Error, Max Error, Stability, Score)
Interactive tuning controls and results display
Live FPS graphs showing PID controller performance

Technical Details

The PID controller works by:

Measuring actual frame times vs. target frame times
Calculating error using smoothed measurements to reduce noise
Adjusting sleep duration using PID mathematics: output = Kp×error + Ki×∫error + Kd×Δerror
Learning from past performance to minimize future timing errors

The system automatically:

Disables VSync to prevent interference with custom frame limiting
Pauses throttling during auto-tuning for accurate measurements
Uses integral windup prevention to maintain stability
Applies high-precision sleep for sub-millisecond timing accuracy

Full Application with Multiple Windows

 },
 OnStart = OnStart,

 OnRender = OnRender,
 OnAppMenu = OnAppMenu,
 });
 }

 private static void OnStart()
 {
 // Initialize your application state
 Console.WriteLine("Application started");
 }

 private static void OnUpdate(float deltaTime)

`ImGuiAppPerformanceSettings` Class

Configuration for performance optimization and throttled rendering. Uses a sophisticated PID controller with high-precision timing to achieve accurate target frame rates while maintaining system resource efficiency. The system combines Thread.Sleep for coarse delays with spin-waiting for sub-millisecond precision, and automatically disables VSync to prevent interference with custom frame limiting.

Example Usage

ImGuiApp.Start(new ImGuiAppConfig
{
 Title = "My Application",
 OnRender = OnRender,
 PerformanceSettings = new ImGuiAppPerformanceSettings
 {
 EnableThrottledRendering = true,
 FocusedFps = 60.0, // Custom higher rate when focused
 UnfocusedFps = 15.0, // Custom rate when unfocused
 IdleFps = 2.0, // Custom very low rate when idle
 NotVisibleFps = 1.0, // Custom ultra-low rate when minimized
 EnableIdleDetection = true,
 IdleTimeoutSeconds = 10.0 // Custom idle timeout
 }
 // PID controller uses optimized defaults: Kp=1.8, Ki=0.048, Kd=0.237
 // For fine-tuning, use Debug > Show Performance Monitor > Start Auto-Tuning
});

This feature automatically:

Uses a PID controller with optimized defaults for highly accurate frame rate targeting
Combines Thread.Sleep with spin-waiting for sub-millisecond timing precision
Disables VSync automatically to prevent interference with custom frame limiting
Detects when the window loses/gains focus and visibility state (minimized/hidden)
Tracks user input (keyboard, mouse movement, clicks, scrolling) for idle detection
Evaluates all applicable throttling conditions and selects the lowest frame rate
Saves significant CPU and GPU resources without affecting user experience
Provides instant transitions between different performance states
Uses conservative defaults: 30 FPS focused, 5 FPS unfocused, 10 FPS idle, 2 FPS not visible

The PID controller learns from timing errors and adapts to your system's characteristics, providing much more accurate frame rate control than simple sleep-based methods. The throttling system uses a "lowest wins" approach - if multiple conditions apply (e.g., unfocused + idle), the lowest frame rate is automatically selected for maximum resource savings.
