5. 3d - Animation

Article automatically translated : We'll be reviewing and optimising it soon ...

After writing the text and gathered a large number of visual references, comes the phase of realization. Often I start production by creating 3D models I intend to use. Then I take care of assigning textures, lights and cameras to use.

A 3D scene can contain only one element which is the object of study with a black background (often for videos on anatomy), or it may be rich in background elements to be present in environment (biology).

After that comes the stage of animation whatsoever for travel cameras in the scene or object animation. Several animation techniques were used depending on the target effect, the special case of particle systems I've used several times to animate the synaptic vesicles, molecules and red blood cells.

Rendering is the production stage during which the multimedia software must produce the final images. Several renderers were used depending on the desired effect.

A sequence may require 10 seconds from 30 seconds to 3 days for rendering on a single machine according to the complexity of the scene. I used my 2 computers simultaneously for network rendering to save time.

Sometimes the construction of 3D models requires the use of complex techniques, this is the case, for example, sections of the brain and cerebellum, which have been drawn from the MRI slices in Illustrator, imported into 3dsmax for creating models and colored in Photoshop. Many of these techniques Ping-Pong between different platforms have been used in various stages of production.

Most of the time I draw multiple versions of the same scene, each containing specific information. This allows me to have more control and flexibility in the phase of post-production. The number of these versions can reach up to 6 for color, isolated objects, the depth of field, shadows, glows, the falloff ...

Sometimes when I consider that a phenomenon can be better explained in 2D, I begin production directly AfterEffect. This is the case for example of the video on nerve impulses or is primarily two-dimensional.
