https://padlet.com/hzng_literalearn/gets1rr In your own words, explain how the visual effects teams created the paintings in motion. en-us 2018-11-27 01:23:56 UTC 2018-12-12 11:53:42 UTC hello@padlet.com https://padlet-assets.s3.amazonaws.com/icons/Folder.png https://padlet.com/hzng_literalearn/gets1rr/wish/311651272 1) There are two part to this, Optical flow and Particle system.

2) Optical flow, or vector field, is a system where a machine view something and try to create an idea of depth. This was then use to generate the paint stroke for every pixel in the image. 

3) Once we are done with optical flow, it is then feed to the particle system, which will generate the effect based on the x and y transformation information from the optical flow. 

4) That is more or less how they did it.]]> 2018-12-06 01:33:19 UTC https://padlet.com/hzng_literalearn/gets1rr/wish/311651272 https://padlet.com/hzng_literalearn/gets1rr/wish/311651418 - They took the concept of optical flow, where every pixel is tracked in a moving image. That is how they did to turn the liveaction scene into moving paintings in those paintings world. 
- They used the vector field which allows it to track pixels from frame one to two. ]]> 2018-12-06 01:34:05 UTC https://padlet.com/hzng_literalearn/gets1rr/wish/311651418 https://padlet.com/hzng_literalearn/gets1rr/wish/311651703 At the time Kodak's Cineon had just released optical flow retimer software. Vincent Ward use this technology to develop the painted world for the movie. They track frame by frame of the live action stills and match the pixelated image with vertical and horizontal graphs. While using the method, they realized that they can change painted pixel image when changing to another frame.]]> 2018-12-06 01:35:25 UTC https://padlet.com/hzng_literalearn/gets1rr/wish/311651703 https://padlet.com/hzng_literalearn/gets1rr/wish/311651753 1)There are using new concept of optical flow.Where every pixel in this movie were tracked to turn live action into painting in motion.

2) Using particle system to capture the image and analyze the color in pixel.

3)Using lidar to helped them generate depth maps and 3D data.

- vector field or an optical flow vector field is using to get the matching between each frame with other frame.
- other way is they are using a particle system which is they take an optical flow to transform the information.]]> 2018-12-06 01:36:35 UTC https://padlet.com/hzng_literalearn/gets1rr/wish/311651875 https://padlet.com/hzng_literalearn/gets1rr/wish/311652070 -visual effect for this movie they using concept of optical flow for the moving painting
-they created a lot of paints strokes to get a different shape and size and then they scan the colour of the pixel.
-they explore the environment for this movie's effect by shot several footage at forest in South Carolina
-using a Lidar to get information the landscape and environment.

Another thing is they use the optical flow.by generating lidar,they are able to scanned the landscape thus getting the information they need for tracking and generating 3d data.the camera movement helps with the moving paint making the paints as if it is smeared.]]> 2018-12-06 01:39:10 UTC https://padlet.com/hzng_literalearn/gets1rr/wish/311652317 https://padlet.com/hzng_literalearn/gets1rr/wish/311652557 The painted world of this movie concept is based of optical flow where the moving image is tracked and turns the particular objects into pantings in motion. 

By using optical flow concept, its basically shows the view of different angles and shots where it is similar to human eyes on how they see the view. So with this 'per pixel' of frame and another frame it gives a depth to the image.]]> 2018-12-06 01:40:32 UTC https://padlet.com/hzng_literalearn/gets1rr/wish/311652557 https://padlet.com/hzng_literalearn/gets1rr/wish/311652669 The visual effect on movie would take the concept of optical flow, where every pixel is tracked in a moving image, to improve the new levels in order to turn liveaction into painting in motion effect. Vincent explored re-touching the live action photography. Looking at romanticist painter casper david fredrich work for inspiration. Kodak's cineon software aand they'd just released for use optical flow re-timer]]> 2018-12-06 01:41:10 UTC https://padlet.com/hzng_literalearn/gets1rr/wish/311652669 https://padlet.com/hzng_literalearn/gets1rr/wish/311652806 What Dreams may come movie is using the concept of optical flow, where every pixel is tracked in a moving image in order to turn liveaction scene into paintings in motion. Optical flow is similar to the way humans eyes see the world and able to understand depth through convergence. Basically it is to match each frame to other frame and give you 'per pixel'. 
In essence, they apply a traditional painter's algorithm and segmented into different alpha channels which give result maybe 10 different maps or different depths. ]]> 2018-12-06 01:41:56 UTC https://padlet.com/hzng_literalearn/gets1rr/wish/311652806 https://padlet.com/hzng_literalearn/gets1rr/wish/311652853 They create the moving paintings by tracking the movements of every pixel which is called the optical flow. Optical flow has its vision from a machine as it is similar to human's eyes so it able to produce a sight of the images and the depth in them. Therefore, they created the images of the paint strokes per pixel.]]> 2018-12-06 01:42:13 UTC https://padlet.com/hzng_literalearn/gets1rr/wish/311652853 https://padlet.com/hzng_literalearn/gets1rr/wish/311655395 The visual effects team created the paintings in motion by using using the optical flow which allows re-timing the footage by using vector field evaluating each pixel and tries to blend in the frames by creating new pixels. The result will look like "Bullet Time" feel and this method is better than frame averaging method which will create ghosting and fading pixels.

The effects team also using particle system software develpoed by Pierre Jasmin to give a painterly feel. The particle system added Monet-ish brush strokes into the footage.

To further enhance the paiterly look effect, the effects team also using Lidar technology which will track the environment by camera movement and later generates the 3d or the depth map which later use to "smear" the footage as if like how the painter smears it's own painting with the paintbrush or fingers]]> 2018-12-06 01:59:55 UTC https://padlet.com/hzng_literalearn/gets1rr/wish/311655395 https://padlet.com/hzng_literalearn/gets1rr/wish/311656357 Base of optical flow technology that create some kind small simple depth of pixelized image of the focussed subject. Then being combined with the particle system that originally was meant to calculate the orientation, depth and variation of axis that involve algorithm that has rgba channel to represent different depth. Both of the technology being combine together to create an paint imagery system that can generate a footage to it full frame.]]> 2018-12-06 02:06:23 UTC https://padlet.com/hzng_literalearn/gets1rr/wish/311656357
