ExoSim’s simulation is interactive now.I added controls for both the planet radius and star radius. Changing either slider updates the 3D objects immediately while the planet continues orbiting. The simulator also calculates the transit depth live using ΔF/F = (Rₚ/R★)², including the conversion between Earth radii and solar radii.I also spent time improving the orbital scene. The planet now travels in front of and behind the star, the orbit path is easier to see, and the star has a rotating generated surface texture, darker spots, lighting, and a softer atmospheric glow instead of looking like a flat yellow circle.Next I’m building the live light-curve graph so the brightness dip matches the simulated transit.
