Wrap Mode
If a texture is transformed in the texture space (using the controls below or the UV Map node),
then it’s possible that areas beyond the image borders will be mapped on the object. The Wrap
Mode determines how the image is applied in these areas.
 Wrap: This wraps the edges of the image around the borders of the image.
 Clamp: The color at the edges of the images is used for texturing. This mode is similar
to the Duplicate mode in the Transform node.
 Black: The image is clipped along its edges. A black color with Alpha = 0 is
used instead.
 Mirror: The image is mirrored in both X and Y.
Texture Filtering Mode
The texture can be filtered differently depending on whether you are using the Software
Renderer or OpenGL renderer in the Renderer 3D node. Within the two render engines, you
can choose between high-quality anti-aliasing or low quality. The texture filtering mode
provides different filtering options for the two render engines and the two anti-aliasing settings.
 Nearest: The simplest filtering technique is very fast but can cause artifacts when
scaling textures.
 Bilinear: A standard isotropic filtering technique for scaling textures into multiple
resolutions. Works well for magnification of textures.
 Trilinear: An extension of Bilinear filtering. Trilinear tends to be a better option when
scaling down textures
 Anisotropic: The highest-quality filtering method that takes the camera orientation and
polygon perspective into account.
 SAT: SAT (Summed Area Table) is a method of performing high-quality filtering, but it
can require more memory than other options. Works very well on smaller bitmaps.
Common Controls
Settings Tab
The Settings tab in the Inspector is duplicated in other 3D nodes. These common controls are
described in detail at the end of this chapter in “The Common Controls” section.
Texture Transform [3TT]
The TextureTransform node
Texture Transform Node Overview
The Texture Transform node can be used to translate, rotate, and scale the UVW texture
coordinates of a 3D object. While the input can also be an image, the output is always
a material.
