This is a simple command-line program that converts an ASCII PLY file to a grayscale PPM image. Faces are colored based on their index in the PLY file. By default, the program outputs a 256x256 PPM image with a fixed camera orientation, but the size of the PPM image and camera orientation can be modified using command-line arguments.
ply2ppm <src> [columns] [rows] [x_deg] [y_deg] [z_deg]
srcspecifies the path to the input PLY file and is a required arguments.columnsandrowsspecify the size of the PPM image in pixels.x_deg,y_deg, andz_degspecify the camera's rotation about the X-axis, Y-axis, and Z-axis, respectively, in degrees.
