0.8.0

Packed Mode
Previously in Taichi, all non-power-of-two dimensions of a field were automatically padded to a power of two. For instance, a field of shape `(18, 65)` would have internal shape `(32, 128)`. Although the padding had many benefits such as allowing fast and convenient bitwise operations for coordinate handling, it would consume potentially much more memory than people thought.

For people indeed want smaller memory usage, we now introduce an optional packed mode. In packed mode, no more padding will be applied so a field will not have a larger internal shape when some of its dimensions are not power-of-two. The downside is that the runtime performance will regress slightly.

A switch named `packed` for `ti.init()` decides whether to use packed mode:
python
ti.init() default: packed=False
a = ti.field(ti.i32, shape=(18, 65)) padded to (32, 128)

python
ti.init(packed=True)
a = ti.field(ti.i32, shape=(18, 65)) no padding

GGUI

A new GUI system, which is codenamed GGUI, is added to Taichi. GGUI will use GPUs for rendering, which enables it to be much faster than the original `ti.gui`, and to render 3d meshes and particles. It also comes with a brand new set of immediate mode widgets APIs.

Sample 3D code:

python
window = ti.ui.Window("Hello Taichi", (1920, 1080))

canvas = window.get_canvas()
scene = ti.ui.Scene()
camera = ti.ui.make_camera()

while window.running:

camera.position(...)
camera.lookat(...)
scene.set_camera(camera)

scene.point_light(pos=(...), color=(...))

vertices, centers, etc. are taichi fields
scene.mesh(vertices, ...)
scene.particles(centers, radius, ...)

canvas.scene(scene)
window.show()


Sample IMGUI code:

python
window = ti.ui.Window("Hello Taichi", (500, 500))
canvas = window.get_canvas()

gx, gy, gz = (0, -9.8, 0)

while window.running:

window.GUI.begin("Greetings", 0.1, 0.1, 0.8, 0.15)
window.GUI.text("Welcome to TaichiCon !")
if window.GUI.button("Bye"):
window.running = False
window.GUI.end()

window.GUI.begin("Gravity", 0.1, 0.3, 0.8, 0.3)
gx = window.GUI.slider_float("x", gx, -10, 10)
gy = window.GUI.slider_float("y", gy, -10, 10)
gz = window.GUI.slider_float("z", gz, -10, 10)
window.GUI.end()

canvas.set_background_color(color)
window.show()

Dynamic SNode Allocation
Previously in Taichi, we cannot allocate new fields after the kernel's execution. Now we can use a new class `FieldsBuilder` to support dynamic allocation.

`FieldsBuilder` has the same data structure declaration API as the previous `root`, such as `dense()`, `pointer()` etc. After declaration, we need to call the `finalize()` function to compile the `FieldsBuilder` to an `SNodeTree` object.

Example usage for `FieldsBuilder`:

py
import taichi as ti
ti.init()

ti.kernel
def func(v: ti.template()):
for I in ti.grouped(v):
v[I] += 1

fb = ti.FieldsBuilder()
x = ti.field(dtype = ti.f32)
fb.dense(ti.ij, (5, 5)).place(x)
fb_snode_tree = fb.finalize() Finalizing the FieldsBuilder and returns a SNodeTree
func(x)

fb2 = ti.FieldsBuilder()
y = ti.field(dtype = ti.f32)
fb2.dense(ti.i, 5).place(y)
fb2_snode_tree = fb2.finalize() Finalizing the FieldsBuilder and returns a SNodeTree
func(y)


Additionally, `root` now is implemented by `FieldsBuilder` implicitly, so we can allocate the fields directly under `root`.
py
import taichi as ti
ti.init() ti.root = ti.FieldsBuilder()

ti.kernel
def func(v: ti.template()):
for I in ti.grouped(v):
v[I] += 1

x = ti.field(dtype = ti.f32)
ti.root.dense(ti.ij, (5, 5)).place(x)
func(x) automatically called ti.root.finalize()
ti.root = new ti.FieldsBuilder()

y = ti.field(dtype = ti.f32)
ti.root.dense(ti.i, 5).place(y)
func(y) automatically called ti.root.finalize()


Furthermore, after we called the `finalize()` of a `FieldsBuilder`, it will return a finalized `SNodeTree` object. If we do not want to use the fields under this `SNodeTree`, we could call `destroy()` manually to recycle the memory into the memory pool.

e.g.:
py
import taichi as ti
ti.init()

ti.kernel
def func(v: ti.template()):
for I in ti.grouped(v):
v[I] += 1

fb = ti.FieldsBuilder()
x = ti.field(dtype = ti.f32)
fb.dense(ti.ij, (5, 5)).place(x)
fb_snode_tree = fb.finalize() Finalizing the FieldsBuilder and returns a SNodeTree
func(x)

fb_snode_tree.destroy()
func(x) cannot be used anymore
