Task Description

Create a high-fidelity 3D visualization demonstrating a point in Spherical Coordinates (r, phi, theta) within the first octant (x, y, z >= 0).

Requirements:

  1. Background: Must use a black background for a premium scientific aesthetic.
  2. Coordinate System: Show X, Y, and Z axes starting from the origin (0,0,0).
  3. Point P: Plot a point P at r=5, phi=pi/4 (45° azimuthal), theta=pi/6 (30° polar from the Z-axis).
  4. Geometric Aids:
    • Draw the vector from the origin to point P.
    • Draw a vertical dashed line from P to its projection P' on the X-Y plane.
    • Draw dashed lines from P' to the X and Y axes.
  5. Angle Markings: Visually indicate or label the angles phi (azimuthal) and theta (polar) to show how they are measured.

Evaluation Criteria:

Your submission will be evaluated by a Vision Language Model (VLM) using the following criteria:

  • The plot must be 3D with a black background.
  • The point must be located in the first octant (upper-front-right quadrant).
  • The polar angle (theta) should be measured from the positive Z-axis.
  • The azimuthal angle (phi) should be measured from the positive X-axis in the X-Y plane.
  • Geometric projections (dashed lines) to the X-Y plane must be accurate.

    # Coordinate transformation
