3D Surface Plots
- Enter a function of
x and y
- Examples:
sin(sqrt(x*x+y*y)), x*y, cos(x)*sin(y)
- Click Render to generate the surface
Controls
- Rotate X: Tilt the view up/down
- Rotate Z: Spin the view left/right
- Surface is colored by height (z-value)
Fractal Types
- Mandelbrot Set: The classic fractal
- Julia Set: Related to Mandelbrot, different formula
- Burning Ship: Absolute value variant
- Tricorn: Complex conjugate variant
Navigation
- Zoom In: Click on the fractal
- Zoom Out: Right-click
- Reset: Click Reset View button
Settings
- Iterations: Higher = more detail but slower
