Determines the type of
Material that is supported by a
MaterialAppearance instance. This is a trade-off between
flexibility (a wide array of materials) and memory/performance
(required vertex format and GLSL shader complexity.成员(属性)
static constant Cesium.MaterialAppearance.MaterialSupport.ALL : MaterialAppearance.MaterialSupportType
All materials, including those that work in tangent space, are supported.
This requires
position, normal, st,
tangent, and bitangent vertex attributes.
static constant Cesium.MaterialAppearance.MaterialSupport.BASIC : MaterialAppearance.MaterialSupportType
Only basic materials, which require just
position and
normal vertex attributes, are supported.
static constant Cesium.MaterialAppearance.MaterialSupport.TEXTURED : MaterialAppearance.MaterialSupportType
Materials with textures, which require
position,
normal, and st vertex attributes,
are supported. The vast majority of materials fall into this category.
