This node represents a simple cone whose central axis is aligned with the y-axis. By default, the cone is centered at (0,0,0) and has a size of -1 to +1 in all three directions. The cone has a radius of
1 at the bottom and a height of 2, with its apex at 1. The cone has two parts: the sides and the bottom.
The cone 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 cone, and the second is used for the bottom. Otherwise,
the first material is used for the entire cone.
When a texture is applied to a cone, it is applied differently to the sides and bottom. On the sides, the texture wraps counterclockwise (from above) starting
at the back of the cone. The texture has a vertical seam at the back, intersecting the yz-plane. For the bottom, a circle is cut out of the texture square and applied to the cone's base circle. The texture
appears right side up when the top of the cone is tilted away from the camera.
