# 📡 How to Use the Advanced Ray Tracer

## 📡 eino's new ray tracing engine is dramatically faster thanks to GPU acceleration, giving you physically accurate RF predictions at high speed. It fully models multi-path, capturing reflections and diffractions from any angle as signals bounce and bend through your real environment — for true-to-life coverage even in the most complex spaces. Because the engine is so fast, you can generate much higher-resolution heatmaps that reveal detail traditional methods simply miss.

🚀 Step 1: Select the Advanced Ray Tracer

Start with a project, then select the **Ray Tracer** button.

- The advanced ray tracer is automatically selected for any **new** project.
- Older projects default to **Ray Tracing Classic**, but can always be changed over to **Ray Tracing Advanced**.

---

📍 Step 2: Place or Move Access Points

- Moving an AP triggers a heatmap calculation.
- Adding an AP also triggers a recalculation.
- The heatmap is recalculated quickly once the AP has been set.

---

⚙️ Step 3: Configure the Advanced Settings

Under **Ray Tracing Advanced**, you can select and adjust:

- **Reflections**
- **Diffractions**
- **Interference Suppression** level
- **Fade Margin** — adjusts the deposited power of the link budget. Increasing the margin effectively increases free space loss.
- **Grid Resolution** — improves the fidelity of the simulation. A coarser grid simulates faster; a finer grid provides more information about the scene but takes slightly longer to process.

✅ The advanced ray tracer is now active, recalculating high-resolution coverage in real time as you place and move APs.
