virtual | ~SoCylinder () |
This node represents a simple capped cylinder centered around the y-axis. By default, the cylinder is centered at (0,0,0) and has a default size of -1 to +1 in all three dimensions. You can use the radius and height fields to create a cylinder with a different size.
The cylinder is transformed by the current cumulative transformation and is drawn with the current lighting model, drawing style, material, and geometric complexity.
If the current material binding is PER_PART
or PER_PART_INDEXED
, the first current material is used for the sides of the cylinder, the second is used for the top, and the third is used for the bottom. Otherwise, the first material is used for the entire cylinder.
When a texture is applied to a cylinder, it is applied differently to the sides, top, and bottom. On the sides, the texture wraps counterclockwise (from above) starting at the back of the cylinder. The texture has a vertical seam at the back, intersecting the yz-plane. For the top and bottom, a circle is cut out of the texture square and applied to the top or bottom circle. The top texture appears right side up when the top of the cylinder is tilted toward the camera, and the bottom texture appears right side up when the top of the cylinder is tilted away from the camera.
