Class SoTexture2Transform

  • All Implemented Interfaces:

    public class SoTexture2Transform
    extends SoNode
    2D texture transformation node. This node defines a 2D transformation applied to texture coordinates. If you are using multiple textures, note that this transformation is applied to the texture coordinates of the current texture unit (SoTextureUnit). This transformation affects the way textures are applied to the surfaces of subsequent shapes. The transformation consists of (in order) a non-uniform scale about an arbitrary center point, a rotation about that same point, and a translation. (Note: while the transformations can be thought of as being applied in that order, the GL matrices are actually premultiplied in the opposite order. Therefore, the operations are listed in the reverse order throughout this reference page.) This allows a user to change the size and position of the textures on objects.

    File format/default:

    Texture2Transform {

      translation 0 0
      rotation 0
      scaleFactor 1 1
      center 0 0

    Action behavior:

    SoGLRenderAction, SoCallbackAction
    Concatenates transformation with the current texture transformation. Sets: SoTextureMatrixElement

    • Field Detail

      • translation

        public final SoSFVec2f translation
        Translation in S and T.
      • rotation

        public final SoSFFloat rotation
        Counterclockwise rotation of the coordinate space, in radians. This results in a clockwise rotation of the texture on the object.
      • scaleFactor

        public final SoSFVec2f scaleFactor
        Scaling factors in S and T.
      • center

        public final SoSFVec2f center
        Center point used for scaling and rotation.

      • SoTexture2Transform

        public SoTexture2Transform()
        Creates a texture transformation node with default settings.
