Tiling—
Controls grain complexity or "distortion."
By increasing this parameter along a given axis, the
grain becomes increasingly compressed and wavy
along that axis. Default=1.0 (X, Y, and Z axes).
Bo x A shows the default on all three axes. Boxes B
and C show progressively higher Tile settings for
the X axis. Incre asing Tile on other axes produces
similar effects.
A: Tile, X axis=1.0 (default)
B: Tile, X axis=4.0
C: Tile, X axis=8.0
Grain Thickness=3
Tile, X axis=4.0 for both
Axial Noise= 1 (lef t), 4 (right)
Grain Thickness=3
By combining Tile with Axial N oise, ev en great er
distor tion is possible. The bottom left box is the
same as B, with Tile at 4.0 on the X axis. The
bottom right bo x adds Axial Noise at 4.0.
Angle—Controls grain direction.
Default Grain: Wood is rendered with the g rain
runningalongtheXaxisoftheobject. Thisis
illustrated by the left cube below. The default angle
is 0 for X, Y, and Z axes.
Rotated Grain: By rotating the direction of the
grain around an axis, you change the rendered
effect. In the right cube, the Y axis is set to 90. This
rotates the g r ain direction 90 degrees around the
Y axis so t hat the grain is now running a long the
Zaxis.
Other Angle Effects: Varying a single angle c an
create distorted grain effects (cylinder at left).
Varyingthethreeanglesbyauniformamount
keeps the grain running parallel through an object
(cylinder at right).
