This is the last week of the group project. We still have a lot of problems to solve. The first is how to combine digital Earth and rendering. I tried to use tracker and 3D tracking. At the end, I chose to use the tracker to track the render, then export Stabilize and matchmove to connect with the footage. At the same time, I need to select the occluded part with roto. The part of combining digital Earth and rendering is more complicated. I had to be very patient and constantly fine-tune in order to make the digital Earth animation look more natural.

I still need to color the render. Because the original rendering only has green light, there is no obvious color contrast. So, I need to color the whole scene and each model through grade and crypto object. I set the whole main color to be green and blue. At the same time, I added a little purple color to the smoke on the aircraft in order to give the whole picture a little bit of contrast between different cold shades.

For this week’s group project, my task was moving the TV off the wall, and placing two AI animations on the wall near the stair. The screenshots are the demonstration of my nuke’s nodes. First, in order to remove the TV, I used the previous clean up method. I removed the TV from the first frame, then used framehold and 3D tracking to remove the TV in each frame.

I made two AI animations, and placed them on the wall near the stair. First, I need to do 3Dtracking on the footage, and then I’m going to make a card at the specified location. After that, I used the cornerpin to place the animations on the wall, and connect them to the card.

According to the new rendering, only a small portion of the TV on the footage is revealed. Therefore, I plan to make another AI animation, and put two screens on the wall. For the new AI animation, my idea is to use after effect to make the data of the earth and the world map.

The task of this week’s group project is to create a technical ui animation. According to the science and technology UI interface in Iron Man, my idea is to make a science and technology interface about human body scanning in after effect. In the interface, I designed several kinds of data statistics and changes, including wavy, circular and so on. This approach makes the interface look more technological. Then I rendered the geometry of two human bodies in maya as fodder for the body scan. Finally, I added a geometric border and turned up the tone and brightness of the whole picture to make it more like a tech screen.

This week’s team project is to create a hologram of digital Earth. My approach was to use the After Effect plugin Form to make a rotating digital earth; at the same time, I put a light under the earth to connect to the hologram equipment. But the rendered sequence will be 2D flat, so I need to do 3D Tracking in nuke to match this digital earth.

The task for this week’s group project is to wipe off another handrail and a fire extinguisher. I did it the same way I did it last time. But when it came to wiping the other armrest, I was faced with a challenge. Due to the camera moved, the background of this handrail moved from the wall to the staircase, so I chose Frame 157 for erasure. At the same time, I used roto to cut out the wall of the original footage and put it in the front to block the movement and deformation of Frame 157. I used the same method to wipe the fire extinguisher.

For the group work, my task is to remove the handrail on the wall. My method is to clear the handrail of frame 200 in photoshop now, and then do 3D tracking in nuke to make the corresponding card according to the position. Then use framehold to lock the image of frame 200 where the armrest has been erased. At the same time, because of the camera movement, the lighting and color of the scene would change, so I added grade to match the color change of the footage.

This week I have continually improved matchmove in 3DEqualizer. Obviously, doing matchmove in 3D Equalizer is not easy since we have to track the correct points in the scene but there are always some bugs. I retrace the unstable tracking points; At the same time, I added some tracking points on the ground. Finally, because I reduced Brower’s Deviation to 0.47, the 3D tracking of this scene became relatively stable. I exported maya files with models and cameras from 3DEqualizer and provided CG lead to build scenes in maya.

This week’s topic is using 3D Equalizer to do 3D tracking. It’s a pretty new technique for me, and help me to understand the process about how to combine 3D file with the actual scene. In 3D Equalizer, we need to set the points on the marks in the scene in order to create a basic camera for tracking.Then we can change the hue or exposure of the scene since this way can help us to create more tacking points and make the camera’s tracking be more stable. We can check if the camera is stable according to the lines and data in Deviation Browser.

If we finish the 3D tracking in 3D Equalizer, we can export the nuke file from 3D Equalizer, and check the camera in nuke.
