Making a cylinder with VPython

pip install vpython

cylinder()

Syntax : cylinder(parameters) Parameters :

• pos : It is the position of the center of one end of the cylinder. Assign a vector containing 3 values, example pos = vector(0, 0, 0)
• axis : It is the axis of alignment of the cylinder. Assign a vector containing 3 values, example axis = vector(1, 2, 1)
• up : It is the orientation of the cylinder. Assign a vector containing 3 values, example up = vector(0, 1, 0)
• color : It is the color of the cylinder. Assign a vector containing 3 values, example color = vector(1, 1, 1) will give the color white
• opacity : It is the opacity of the cylinder. Assign a floating value in which 1 is the most opaque and 0 the least opaque, example opacity = 0.5
• shininess : It is the shininess of the cylinder. Assign a floating value in which 1 is the most shiny and 0 the least shiny, example shininess = 0.6
• emissive : It is the emissivity of the cylinder. Assign a boolean value in which True is emissive and False is not emissive, example emissivity = False
• texture : It is the texture of the cylinder. Assign the required texture from the textures class, example texture = textures.stucco
• length : It is the length of the cylinder. Assign a floating value, the default length is 1, example length = 10
• radius : It is the radius of the cylinder. Assign a floating value, the default height is 1, example radius = 5
• size : It is the size of the cylinder. Assign a vector containing 3 values representing the length, height and width respectively, example size = vector(1, 1, 1)

All the parameters are optional.
