For the start of this class we again looked at working in the 3D scene and worked a little bit with the 3D environment by placing a card to represent the wall and see if we could add something to the wall. We added a color-wheel, I moved this in the 3D environment to the card that will be in the same place as the wall in the video.
We also woked with the RotoPaint to patch up things that we want to remove out of our scene. This is also what we did last term but now we conclude this with the 3D camera we use. As shown in the images below we put an framehold on the video and the camera we added and Roto out the parts we want to remove. As an example he showed us how he removed a pole that is shown on the scene, I adapted to this and try the same but then with the red door. This door had what I assume are emergency exits plates on them and got rid of these
After this he also showed us how to create a 3D mesh for our 3D scene so we can get a clear vision of how we move through the 3D space in the video. For this we use the Point cloud generator node which crates a calculated number of points that track how the camera moves through the space. After using this we add the possion mesh node under this This leaves us with a almost completely closed off mesh of the 3D scene. (see images below)
We can also create our 3D mesh scene by tracking the points and creating a baked group. The bake will pop up as its own node called baked mesh, The is in my opinion a little clearer for the eye since this wont be a almost solid mesh but will show us an open mesh of where the streets would be and where the buildings are. (see images below)
As you see in the 2 meshes above that they are both quite rough sketches and this not always works for the best. You can also just use the camera tracker tool and create your own 3D cards to fill up different elements in your scene. As shown below I have tried this for the different doors. the right door was shown in class as an example and I added 2 extra examples on the left side to understand what I was doing.
For the homework we had to start on the scene he gave us. In this scene we kind of had to recreate an example he had shown us during class. This was to add 2 floors, one for the foreground and one for the background and also a wall for the background. In his example he also added some 3D objects, so for mine I added 2 cubes in the foreground and a circle in the background as a example as well. and lastly I added the red tracker pointers to the walls and the ground directing at the already physical placed in the scene.
With all these new techniques learned we got given another example of a scene were had to work with the camera tracker. In this scene Gonzalo showed us some examples he did which were creating the different cards in the scene and a door replacement. He told us to play around with this scene and see what we would be able to implement in the area that we think would work in the scene.
I searched online and found 2 different animal images that I thought would fit in the scene. I also went on my Ipad in procreate to create a graffiti like text to add to the total image.
Below this text you see how I made the scene in Nuke. I created a camera track and used the camera to implement the cards in the right places. I color correct and graded the 2 images to where it would fit better in the scene. I also gave the images some cracks with the rotoscope to give it a little bit more of a raw edge. I used corner pin to slide the image to the right position and put them next to each other on the wall. To give the scene a little bit more of a story I wrote down ‘People are animals’ and placed this text over the two posters.
