VFX Breakdowns
The techniques that was used in the avenger’s endgame breakdown was slides and dropdowns mainly because many of the shorts the sets have the majority built up around it an example of this is to extend the building to show that is where its extended. Dropdowns are also used mostly when they are showing layers of ground environment also a short were there are on army base its highlighted what they have done because it’s not that obvious its one of the realism shot with in the move that why Its highlighted in the breakdown. The narrative of this breakdown is similar to the movies timeline revelling how it’s being done.
3D Scanning
In this weeks lesson i was introduced to 3D scanning for this we used Skanect makes it easy to 3D scan different kind of scenes by providing a set of scenarios it can acquire dense 3D information about a scene at up to 30 frames per second. Just move around your Structure Sensor. The sensor was attached to an iPad we had a bounding box which could be adjusted the smaller the box the more detail you could get and this was ideal for face scanning and if the box was bigger it would be for a full body scan . When we began to scan the green shows when its good to scan and if your position is off it will go red when its finished you can put in to colorize i learnt to turn of prioritise fist-frame that means it doest just show from when you first start recoding. One of the things that i noticed from Skanect is that it picks up clothing really well but struggles with hair and finer detail , i also changed the lights around this had no effect to the finished work
Photogrammetry
Photogrammetry can be used in difference industries within the media industry the technology captures the photographs of subjects from different angles and after that with the use of computational geometry algorithms and computer vision the captured photographs or 2d images of objects are reconstructed into their 3D form. Photogrammetry is the art or technology of taking measurements from photograph images It recovers the exact positions of surface points Combination of powerful computational geometry algorithms and computer vision are used Basic principle is to analyse photographs of a static subject captured from different viewpoints.
Retoplogise
Retopology lets you create new topology based on the features of a reference surface. Maya's retopology toolset offers a streamlined, one tool workflow that lets modelers focus on the creative process instead of edge flow and polygon count.
