businessman 3d model

Convert the input flat image into a 3D model, setting the base plane height to 0. Adjust the model's height based on the black, white, and gray tones in the image, following these rules: White (RGB 255,255,255) has a height of 0cm and is fully transparent. Black (RGB 0,0,0) has a height of 2cm. Gray tones linearly interpolate the height between 0cm (white) and 2cm (black), with darker grays corresponding to greater heights. Ensure smooth height transitions, preserve image details, and generate an accurate 3D structure.
