DESCRIPTION¶

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.

FIELDS¶

SoSFBitMask parts

Visible parts of cylinder.

SoSFFloat radius

SoSFFloat height

Define the cylinder's height and radius; values must be greater than 0.0.

METHODS¶

SoCylinder()

Creates a cylinder node with default settings.

void addPart(SoCylinder::Part part)

void removePart(SoCylinder::Part part)

These are convenience functions that make it easy to turn on or off a part of the cylinder.

SbBool hasPart(SoCylinder::Part part) const

This convenience function returns whether a given part is on or off.

static SoType getClassTypeId()

Returns type identifier for this class.

ACTION BEHAVIOR¶

SoGLRenderAction

Draws cylinder based on the current coordinates, materials, drawing style, and so on.

SoRayPickAction

Intersects the ray with the cylinder. The part of the cylinder that was picked is available from the SoCylinderDetail.

SoGetBoundingBoxAction

Computes the bounding box that encloses the cylinder.

SoCallbackAction

If any triangle callbacks are registered with the action, they will be invoked for each successive triangle that approximates the cylinder.
