Shape Control Mechanisms

Shape Control Mechanisms

Shape Control Mechanisms Shape Control Mechanisms The shape control mechanisms that are most prevalent in 3D animation are blend shapes and morph targets. Morphing is a technique that combines multiple shapes into a single expression or what is called an absolute...
Muscle Deformers

Muscle Deformers

Muscle Deformers Muscle Deformers The third type of skin deformers and the most computation expensive system of shape control is the Muscle System. This type of deformer brings the most realistic results, due to its ability to slide geometrical skin over underlying...
Morph Deformers

Morph Deformers

Morph Deformers Morph Deformers The Morph Deformer or the Blend Shape is the ultimate one of skin deformers and is used where the total control over the shape of deformation is required. The Non-Rigid deformer will only get you half way to your desired shape by moving...
Joint Deformers

Joint Deformers

Joint Deformers Joint Deformers The most basic type of skin deformers is the Joint Deformer. It is usually based on deformations of Rigid or Non-Rigid type and is driven by bone or joint binds. By binding vertexes to certain joints we are able to move clusters of...
Skin Deformers

Skin Deformers

Skin Deformers Skin Deformers 3D Applications have a few basic types of skin deformers which artists can utilise to drive skin deformations. Some of them are: Joints/Bones, Clusters, Sculpt Deformers and Blend Targets. The main of the ones listed above is Joints and...
Skin Geometry

Skin Geometry

Skin Geometry Skin Geometry The person's skin geometry is derived from the 3d capture volume and in the 3D Scan Cleanup stage, most often, gets optimised. Initially, this is done by the photogrammetry software(Agisoft Photoscan) to reduce the polygon count in areas...

Digital Double Anatomy

Digital Double Anatomy Digital Double Anatomy All Digital Doubles consist of a few basic organs. The first one is Skin, second is Skin Deformer and the third one is Skin Deformer Control Rig. The Skin is the visible outer layer of a Digital Double. This is the layer...

Skin Shaders in Games and VFX

Skin Shaders in Games and VFX Skin Shaders Skin Shaders in Games and VFX is another broad topic. In our previous article on Digital Skin we've talked about geometrical and color properties of skin, but that is not all! The way the actual "look" of Digital Skin is...
Digital Skin for Digital Doubles

Digital Skin for Digital Doubles

Digital Skin for Digital Doubles Digital Double Skin What is captured during the 3d scanning session is a state of a person at a point in time, their wrapper, their digital skin. That initial state gets broken down into different effect dimensions, depending on the...
