2.8.10.8 Pattern Modifiers

Modify the evaluation of a pattern function:
PATTERN_MODIFIERS:
Jump to SDL
[TURBULENCE] & [WARP...] & [TRANSFORMATION...] & [noise_generator NG_TYPE]
NG_TYPE:
1 | 2 | 3
TURBULENCE:
turbulence VECTOR & [octaves INT] & [omega FLOAT] & [lambda FLOAT]
WARP:
warp { WARP_ITEM }
WARP_ITEM:
REPEAT_WARP | BLACK_HOLE_WARP | TURBULENCE | CYLINDRICAL_WARP | SPHERICAL_WARP | TOROIDAL_WARP | PLANAR_WARP
REPEAT_WARP:
repeat VECTOR [offset VECTOR] [flip VECTOR]
BLACK_HOLE_WARP:
black_hole V_LOCATION, F_RADIUS [BLACK_HOLE_ITEMS]
BLACK_HOLE_ITEMS:
[strength FLOAT] & [falloff FLOAT] & [inverse] & [repeat VECTOR [turbulence VECTOR]]
CYLINDRICAL_WARP:
cylindrical [orientation VECTOR] [dist_exp FLOAT]
SPHERICAL_WARP:
spherical [orientation VECTOR] [dist_exp FLOAT]
TOROIDAL_WARP:
toroidal [orientation VECTOR] [dist_exp FLOAT] [major_radius FLOAT]
PLANAR_WARP:
planar [V_NORMAL, F_DISTANCE]
Modify the usage of a blend map:
BLEND_MAP_MODIFIERS:
Jump to SDL
[frequency FLOAT] & [phase FLOAT] & [WAVEFORM]
WAVEFORM:
Jump to SDL
ramp_wave | triangle_wave | sine_wave | scallop_wave | cubic_wave | poly_wave [F_EXPONENT]
Specify a two-dimensional bitmap image for a pattern:
BITMAP_IMAGE:
FUNCTION_IMAGE | BITMAP_TYPE FILE_NAME
FUNCTION_IMAGE:
Jump to SDL
function I_WIDTH, I_HEIGHT { FUNCTION_IMAGE_BODY }
FUNCTION_IMAGE_BODY:
PIGMENT | FN_FLOAT | pattern { PATTERN [PATTERN_MODIFIERS] }
PATTERN:
MAP_PATTERN | brick [BRICK_ITEMS] | checker | hexagon | object { LIST_OBJECT }
BITMAP_TYPE:
Jump to SDL
gif | tga | iff | ppm | pgm | png | jpeg | tiff | sys
Modify how a 2-D bitmap is to be applied to a 3-D surface:
BITMAP_MODIFIERS:
Jump to SDL
[once] & [map_type MAP_TYPE] & [interpolate INTERPOLATE_TYPE]
MAP_TYPE:
0 | 1 | 2 | 5
INTERPOLATE_TYPE:
2 | 4
