1. The teacher informed us of the main topics of study for the semester
   • Will produce an animation through two weeks
   • Will do more of the design part of the stuff
   • Will create a loop animation
2. Teach us how to create keyframe animations
   • Making a small ball with elastic potential energy to roll down a step
   • Making a ball that does not have elastic potential energy to roll down a step
3. Talked about object calculations in Maya – mainly collisions
   • Produced free-falling objects
   • Made objects that collide with each other
   • Objects made to move along an axis

how to create keyframe animations

1.Making a small ball with elastic potential energy to roll down a step

First step:make a stair

Second step:

Make a small ball and freeze its position.
Give it a keyframe for the y-axis and a keyframe for the z-axis position on the first and 120th frames respectively.

Third step:

Open the graphic editor.

Start by adjusting the z-axis curve to a straight line.
Then keyframe the y-axis curve when the ball moves to the corresponding position and adjust the slope at both ends.

Fifth step:

Give the material and render it.

2.Making a ball that does not have elastic potential energy to roll down a step

First step:

Make a small ball and freeze its position.
Give it a keyframe for the y-axis and a keyframe for the z-axis position on the first and 120th frames respectively.

Second step:

Open the graphic editor.

Start by adjusting the z-axis curve to a straight line.
Then keyframe the y-axis curve when the ball moves to the corresponding position and adjust the slope at both ends.

Because this time the ball has no elastic potential energy it will roll down the steps, and at each level it will move in near free fall.

Third step:

Give the material and render it.

How to make a physical collision

Step 1: Make a square and a plane. Give the square an active rigid body and the plane a passive rigid body and change the collision volume shape of the plane to a plane. This way the square body will fall freely from a height and stop at the plane.

Step 2: Place the two colliding bodies together and give them a force. They will then collide with each other.

Step 3: How to make an object that rotates on its axis.
First make a flat cube, then give it an active rigid body and then give it a rigid body constraint.

Problems I encountered.

1. why can’t I apply boolean operations in bullets and why it quadruples.
2. Be aware that you need to pull the bullet out of the window first
3. The collision volume also needs to be readjusted when using special copy

This week we added tongues to people, and then our teacher had us do some rendering setups. This allowed us to render the person and create post effects.

In the meantime I fixed some of the problems that came up in the last lesson, so now I can animate! It doesn’t work very well but it’s moving!

The main thing we did this week was to import a movie and its corresponding audio in maya, and then use this movie to create a face animation against it.
I divided the class into three parts, in the first part we recorded the video with obs and then rendered it into a frame-by-frame JPEG in AE. we also exported a wave audio file.
The second part was to import the JPEG into the MAYA shot reference, but it’s worth mentioning that we didn’t import the video directly, but imported the image and then adjusted it to identify the sequence frames.
The third part is to k-frame the mouthpiece and skeleton according to the already created and reference image.

I had super problems with this class! It started out with me not being able to adjust my mouth open and shut through my bones. I thought at first it was because of the weights, then I realized I couldn’t even adjust the weights. But after the instructor helped me reopen it all worked out naturally, so I haven’t found out exactly what it is until now.
Then I noticed that whenever I tried to sculpt maya would flash back! So I couldn’t make my expressions. Then I deleted all the timelines I had made because I realized that it was making maya calculate more than the computer could handle.
The last thing I noticed was that my expressions were very distorted, but I guess that was a weighting issue. But no matter how I adjust it, it’s ugly.

There were no more empty computers in the classroom at that time, because three computers were rendering. And I had a bit of a fever at the time, so I went home and took an online class after seeing that there were no computers available. But during the class I found that the course had no sound, despite having adjusted it. So I watched the replay (which had sound for this part) after it was over. The course was mostly refining the previous content.

In this lesson we are binding bones to our head, we made six bones and skinned it. I got a little bit caught up from this part because I don’t know why the open mouth movement I controlled through the skeleton looks like an unfolding cave. And I don’t know what step is wrong, maybe it’s not quite right when it comes to the topology or the uv.

In this lesson we use material balls and uv for uv mapping and adjustment of human head.

We first used the camera to tile the uv, and then used the capture tool to adjust it after cutting a part from the middle.

In this lesson we started to make a human head, we downloaded a human head and material mapping from the internet, then we started to make a topology for it, drawing quadrilateral shapes and then laying half of the face. After that we used symmetry to make the whole face. After this we started to draw the back of the head to fill it up.

In this lesson we worked mainly on completing some hot air balloon details, adding balloon hoops and adding some rope details. The balloon was then textured and animated and rendered.

We made a lot of things this week, in the morning we made wine glasses and glasses, and in the afternoon we made hot air balloons.
In the morning we initially made a jar with curved rotations and then used the same principle to make a wine bottle and a wine glass. But something went wrong when I was making it, I don’t know why it was black all over. So I went to ask the teacher, who said it was because the direction of the face was reversed, so just reverse it. Then I made my cup and wine glass, and set the material to glass, added the background and rendered it.
In the afternoon we started to make the hot air balloon. There are two main parts, the top balloon and the bottom frame. For the top balloon, in order to make the lines, we chose to select the spaced lines and shrink them to get the original look. Then we selected the spacing points below to drag it out, forming the small tip below. So the top half is basically complete. Then we started making the box and the string below (the string was really hard!) . The frame is divided into three parts, the top protruding border, the middle connection and the bottom. I asked my teacher why, and she explained to me that it was because the points on the sides of the arcs were too far apart, so it looked like two arcs put together in a circle and ignored the straight line in the middle. So I added the lines on the sides to make it look better. The line is divided into four parts, so just make a quarter and then duplicate it to make the result. First make three circles and then twist and curve them to get the cable, then adjust the angle and detail by soft selection. Then duplicate the four and link the balloons and boxes you made before.
There is really a lot of content in this lesson, so I need to review it again after the lesson to fully grasp it.
