DESCRIPTION

This node defines a 2D transformation applied to texture coordinates. This 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.

FIELDS

SoSFVec2f translation

Translation in S and T.

SoSFFloat rotation

Counter-clockwise rotation of the coordinate space, in radians. This results in a clockwise rotation of the texture on the object.

SoSFVec2f scaleFactor

Scaling factors in S and T.

SoSFVec2f center

Center point used for scaling and rotation.

METHODS

SoTexture2Transform()

Creates a texture transformation node with default settings.

static SoType getClassTypeId()

Returns type identifier for this class.

ACTION BEHAVIOR

SoGLRenderAction, SoCallbackAction

Concatenates transformation with the current texture transformation.
