Detailed Description

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.

Member Data Documentation

SoSFVec2f SoTexture2Transform::center

Center point used for scaling and rotation.

SoSFFloat SoTexture2Transform::rotation

Counterclockwise rotation of the coordinate space, in radians.

This results in a clockwise rotation of the texture on the object.
