Enumeration members

FeatureGeometry

FeatureGeometry:

Attributes that affect generation of feature geometry and thus must be resolved at decoding time.

remarks

They may have huge variancy as they are implemented as vertex attributes or embedded in generated meshes.

These attributes are available only in decoding scope.

TechniqueGeometry

TechniqueGeometry:

Attributes that are common to whole group of features drawn with this technique. These attributes affect generated geometry and thus must be resolved at decoding time.

remarks

They shouldn't have big variancy and evaluate to at least dozens of values as each combination of these attributes consitute new technique and material.

These attributes are available in decoding and rendering scope.

TechniqueRendering

TechniqueRendering:

Attributes that are common to whole group of features drawn with this technique.

remarks

Attributes that can be changed in resulting object/material from frame to frame. They are usually implemented as uniforms.

These attributes may be available only at rendering scope.
