The following Gen operators are unique to the
jit.gen
,
jit.pix
, and
jit.gl.pix
objects - unlike the
Common Gen Operators
, they are only used in the matrix/texture domain.
Color
hsl2rgb :
Convert HSL to RGB, preserving alpha
rgb2hsl :
Convert RGB to HSL, preserving alpha
Coordinate
cell :
Cell coordinates of input matrix [0, dim-1]
dim :
Dimensions of input matrix
norm :
Normalized coordinates of input matrix [0, 1]
snorm :
Signed normalized coordinates of input matrix [-1, 1]
Quaternion
qconj :
Get the conjugate of a quaternion.
qmul :
Multiply quaternion inputs
qrot :
Rotate a vector by a quaternion. The equation of the rotation is q*v*q^-1.
Sampling
nearest :
Nearest neighbor sample a matrix at a given coordinate (normalized). Nearest has a boundmode attribute that can be set to wrap, mirror or clamp.
nearestpix :
Nearest neighbor sample a matrix at a given coordinate (in pixels). Nearest has a boundmode attribute that can be set to wrap, mirror or clamp.
sample :
Sample a matrix at a given coordinate (normalized) with linear interpolation. Sample has a boundmode attribute that can be set to wrap, mirror or clamp.
samplepix :
Sample a matrix at a given coordinate (in pixels) with linear interpolation. Pixel centers are located at PIXEL+0.5. For example, the center of the upper-left pixel is (0.5, 0.5). Samplepix has a boundmode attribute that can be set to wrap, mirror or clamp.
Surface
circle :
Equation of a circle taking input coordinates ranging from [0, 1]
cone :
Equation of a cone taking input coordinates ranging from [0, 1]
cylinder :
Equation of a cylinder taking input coordinates ranging from [0, 1]
plane :
Equation of a plane taking input coordinates ranging from [0, 1]
sphere :
Equation of a sphere taking input coordinates ranging from [0, 1]
torus :
Equation of a torus taking input coordinates ranging from [0, 1]
Vector
concat :
Concatenate vector values into a larger vector
cross :
Take the cross product of two vectors
dot :
Take the dot product of two vectors
faceforward :
Return a vector pointing in the same direction as another
length :
Returns the length of a vector
normalize :
Normalize a vector to unit length
reflect :
Reflect a vector off a surface defined by a normal
refract :
Refract a vector through a surface defined by a normal and a refraction index
rotor :
Return a quaternion that can rotate the first input into the second.
