v0.0.11

• Fix #12 where TaichiOperations cannot be found
• Bumped taichi version to v0.7.18.

v0.0.10

PyPI packages:

• Remove unexpected p and s directory in wheel file (sorry!)
• Bump Taichi requirement to v0.6.32.

GUI system:

• Support choosing ipython or matplotlib as backend in ts.Animation, e.g.:

self.gui_backend = 'ipython'

This would allows you to display GUI result in Jupyter notebook, checkout the config file.

Field sampling:

• dflSample(field, P, dfl): return a default value dfl when P out of range.

v0.0.9

1. Upgrade to Taichi new syntax:

• ti.var -> ti.field
• ti.Vector -> ti.Vector.field

2. Examples upgrade to Code Format.
3. Fix ts.randInt not returning correct range for new Taichi version.
4. Fix ts.ballBoundReflect raising NameError.
5. Functions like ts.mix are now @ti.pyfunc to be called from both Python/Taichi-scope.

v0.0.8

Color map:

• blueorange (the same one used in Taichi THREE)

SPH kernel functions:

• spiky
• ploy6
• dspiky
• dploy6

ODOP classes:

• TaichiClass for generic base of Taichi ODOP data classes (WIP)
• Complex based on TaichiClass (use c @ c for multiply, WIP)

Taichi hacks:

• matrix.T, a shortcut for matrix.transpose()
• vector.L, a shortcut for vector.norm()
• vector.L2, a shortcut for vector.norm_sqr()
• vector.N, a shortcut for vector.normalized()
• ti.pi, a shortcut for math.pi
• ti.tau, a shortcut for math.tau

Vector math:

• vector.Yx, a shortcut for tl.vec(vector.y, vector.x), and what's more:
• If u = tl.vec(2, 3, 4, 5), then u.y_xW is (3, 0, 2, -5)

Field sampling:

• D = tl.vec(1, 0, -1), e.g.: use D.yxy or D._x_ to get tl.vec(0, 1, 0)

v0.0.7

Field sampling:

• sample (nearest+clamp sample)
• bilerp (bilinear+clamp sample)
• superSample2x2 (anti-aliasing)

Vector math:

• normalizePow (use normalizePow(x_ij, -2) to calculate gravity)

Painting helpers:

• paintArrow (simply feed the image tensor)
• sdLine (SDF of a line segment)

Builtin images:

• imageTaichi (from taichi/examples/taichi_logo.py)
• imageChess (NxN black-white checkers)
• imageGrid (NxN black stroke grid)

Particle simulation:

• ballBoundReflect (often used in cloth simulation)

Color mapping:

• grayscale
• normalmap

GUI base class:

• Set self.auto_clean = True to clear image before on_render.

Taichi hacks:

• Turn off the annoying deprecation warning by default.
• No error on vector = scalar, use vector.fill(scalar) by default.
• vector.product() to get the product of all elements.
• ti.static now accept any argument types.

v0.0.6

Added classes:

• Animation - a Shadertoy-alike GUI base class, including uniforms like self.iMouse! Click here for documentation.

Added functions:

• boundReflect - used to compute particles bouncing with rectangular boundaries.

Dependencies:

• taichi: bump from >=0.6.9 to >=0.6.12.

(Sorry for the delayed release! My computer gets wrong... and I have to reinstall everything from OS to Taichi..)

The Animation class in this release is really a big job, please feel free to feed back if you have any idea!

v0.0.5

New features:

• Access vector shuffled components as vector using v.xy, v.yx! For example:

v = vec3(1, 2, 3)
v.xy  # vec2(1, 2)
v.yx  # vec2(2, 1)
v.zyx  # vec2(3, 2, 1)
v.z  # 3

Added classes:

• TaichiClass for ODOP infrastructure, documentation WIP.

Added functions:

• inversesqrt
• invLength
• sqrLength

Taichi hijackers:

• ti.Vector.var now supported in lower Taichi version.
• ti.static now support all type of inputs and no error will be raised!

Let me know if you feel like some of these changes or not by opening an issue on GitHub.

v0.0.4

Added features:
vec now support GLSL-alike composing from vectors, e.g.:

u = vec(2, 3)  # scalar + scalar = 2D vector
v = vec(u, 3)  # 2D vector + scalar = 3D vector

vec2, vec3 now also supports fill vector with a scalar, e.g.:

u = vec2(0)  # u = vec(0, 0)
v = vec3(3)  # v = vec(3, 3, 3)

New module ts.phys with function momentumExchange.
May be used to exchange momentum when collision.

Added functions:

• randUnit3D
• vec2
• vec3
• vec4
• momentumExchange

v0.0.3

News:
Documentation now available at https://taichi-glsl.rtfd.io!

Added functions:

• reflect
• refract
• rand
• randND
• randRange
• randNDRange
• randUnit2D
• randSolid2D
• rand

v0.0.2

Added functions:

• exp
• log
• tensor (unlike array shape default to None)
• vec_tensor
• mat_tensor
• isinf
• isnan (taichi-dev/taichi#1223)
