Week 7: Smoke sim in houdini

https://www.sidefx.com/docs/houdini/shelf/pyro_wispysmoke.html

Feedback:

1.The weight of the smoke seems too heavy,we need a light one

2.the animation of the robot stil can not be matched in animation in maya

The first vision:

Week3&4

The two weeks were spent defining the form of the project and how it would be produced.
The plan is to use zbrush to sculpt the figure’s pose and then model it in blender and paint the mapping in PS

The main idea is to express the relationship between children and their mothers
The main subject is an abstract sculpture of a mother
She is shedding a single tear
Each tear contains a scene, which I wanted to use to allude to the four stages of the relationship with the mother

Stage 1 / first tear: our mother’s hands are carefully caring for us, we have a close relationship with her

Stage 2 / Second Tears: we grow up and as adolescents we begin to have more misunderstandings and disconnects with our mothers

Stage 3/Third tear: We become independent adults and leave home to live in the middle of nowhere, but from time to time we miss our mothers in faraway places.

Stage 4 / Fourth Tears: We reach the age when our mother is no longer in the world and her life ends, but she becomes a tree, a cloud, and with one breath she becomes everything in the world, leaving us with nothing but a sigh of relief.

About engraving, as I have not studied art systematically
So this step will be difficult for me
I tried to find a lot of pose reference drawings to try to create as accurate a pose as possible

Regarding the narrative of the content in the tears, I also found some references to make a good narrative

Week 6: Setting up the scene in houdini

Due to the matchmove camera is based on 3DE and Maya, so the first step is to export the camera that we got and import into houdini.

In Maya

1. Export camera as the Alembic file

Select Cache > Alembic Cache > Export All to Alembic >select the “World Space” >Export

The most important thing:

Make sure to add the “World Space” to the abc camera

2. Export the animation

  1. Select all the objects in group
  2. From the main menu bar, select Key > Bake Animation >
  3. Click Bake

In the Bake Simulation Options window, select the bake options you want to use. For example:

  • Use the Bake To options to specify whether you want the animation baked to the BaseAnimation, or to a new layer.
  • Set Baked layers to Remove Attributes if you want the selected object’s attributes removed from any associated layers after their animation is baked.Attention: When Baked layers is set to Remove Attributes, the selected object’s keys will be removed from any associated layer that is not muted. If your workflow is to use layers like takes, mute all layers with keys that you want to preserve before baking layers.
  • Turn Smart Bake on if you do not need your result animation to have one key per frame

After baking, Export the same way as the camera(world space should also be applyed)

In Houdini

1. File ▸ Import ▸ Alembic Scene in the main menus to quickly set up an Alembic Archive object

2. Make sure the resolution is the same as the maya camera

add the camera background as the reference

3.Add a null to control the camera and the object

Week 5: Smoke sim by Fulid in Maya

After trying a variety of methods (replicating keyframes and replacing them with small balls, using parent-child animation for the emission source, etc.) to no avail, I followed the advice to use the more stable maya fluid to create smoke

1.Create a fluid container

In this project, I wanted to have part of the robot as the launch source, so I used the box below it as the container

choose the auto-size,cause I do not want my sim is be trapped in the container box

2.Select the container, and click the fluidShape tab in the Attribute Editor

3.Create fluids cache files

After all the adjustments of the sim,then try to create the cache

  1. Select the fluid container.
  2. Select nCache > Create New Cache > Maya Fluid > .
  3. In the Create Fluid nCache Options, set creation options, if necessary, and then click the Create button.
  4. Maya creates a fluids playback nCache file for the selected fluid container.

4. Render

The final result:

The problem is when I try to render the smoke(fluids in maya) in Arnold . No matter how I adjust my parameters, the box border is always there.

Week 4: Smoke Sim by Bifrost

Set the main sim object as the “Aero”.

If we need the collider—select the collider objet

Add more noises,such as motion field

Problems:

The sim test can’t be apply to the animated object at the right position. I have asked the tutors for hrlp,but no one can figure it out.

Then I try to use another way to make thie sim

Week 3 :Tracking in 3DEqualizer

The final tracking test:

Tutorial:

https://www.3dequalizer.com/?site=tutorials

the full process including importing in Maya

Important steps:

1.Import footage & Add trackers

remember to end the point while it is done.

2.Calculating

Calculation—use the result

To delete the wrong point until the average result is under 0.5

3. Distortion & Parameter Adjustment

Attribute Editor—- Lens—adjust

After all the steps, calculate again and ingore the wrong point

4. set planes and orginal

ALT+ SHIFT +select the points

and set orginal point

then set the same point

add a cube

select a point and the cube(alt+shift),then snap to point and align to global space

5. Import into nuke

Personal project proposal–Week 1&2

Introduction

For this personal project I chose to make a sculpture. The content is an abstract image of a mother in tears, tears falling drop by drop, through each tear, you can find that they contain different scenes, these scenes are all daily scenes (cradle, holding hands and playing together, quarrels during the rebellious period, children leaving home when they grow up)

background:

Although my main direction is still special effects (simulation) as well as compositing. But for this personal project I really want to do sculpting, modeling and material work. This theme has been in my mind for a long time. I feel that technology should be used for creative and artistic expression, and I would like to take advantage of the free time I have at school to create what I want to express, as opposed to working.

Inspiration and Reference

https://www.behance.net/gallery/165418225/Fairy-house-in-a-Blender?tracking_source=search_projects%7Ctear+3d

What I want to express is the bond with mother and some remorse and relief of the way they get along with their family, whether mother or themselves is the first time to assume this role, we may not know how to express love, and clumsy in getting along to learn and hurt each other. Only after growing up did I realize how difficult it is to be a mother, and now I have finally convinced my once stubborn and impulsive self to express love properly, as well as to face up to the love of others for me!

Term2-Week 8: Remove Markers

1. Tracking every marker if the result is not very well—try to adjust the grade (blackpoint/whitepoint/gamma) and scale down the tracking area


The comparison of big area and small area

2. link the tracker and the roto area(Roto–Ellipse)

3.add texture

A good way to cover up!

4.the full nodes
