Detailed Description

This node represents a cuboid aligned with the coordinate axes. By default, the cube is centered at (0,0,0) and measures 2 units in each dimension, from -1 to +1. The cube 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, PER_PART_INDEXED, PER_FACE, or PER_FACE_INDEXED, materials will be bound to the faces of the cube in this order: front, back, left, right, top, and bottom.

Textures are applied individually to each face of the cube; the entire texture goes on each face. On the front, back, right, and left sides of the cube, the texture is applied right side up. On the top, the texture appears right side up when the top of the cube is tilted toward the camera. On the bottom, the texture appears right side up when the top of the cube is tilted away from the camera.

Action Behavior

: SoGLRenderAction
Draws cube based on the current coordinates, materials, drawing style, and so on.

: SoRayPickAction
Intersects the ray with the cube. The face of the cube that was picked is available from the SoCubeDetail.

: SoGetBoundingBoxAction
Computes the bounding box that encloses the cube.

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