VertexFormat

new VertexFormat(options)

A vertex format defines what attributes make up a vertex. A VertexFormat can be provided to a Geometry to request that certain properties be computed, e.g., just position, position and normal, etc.
Name Type Description
options Object optional An object with boolean properties corresponding to VertexFormat properties as shown in the code example.
Example:
// Create a vertex format with position and 2D texture coordinate attributes.
var format = new Cesium.VertexFormat({
  position : true,
  st : true
});

Members

staticconstantVertexFormat.ALL :VertexFormat

An immutable vertex format with all well-known attributes: position, normal, st, binormal, and tangent.
See:
Source: Core/VertexFormat.js, line 165

staticconstantVertexFormat.DEFAULT :VertexFormat

An immutable vertex format with position, normal, and st attributes. This is compatible with most appearances and materials; however normal and st attributes are not always required. When this is known in advance, another VertexFormat should be used.
See:
Source: Core/VertexFormat.js, line 185

staticconstantVertexFormat.POSITION_AND_NORMAL :VertexFormat

An immutable vertex format with position and normal attributes. This is compatible with per-instance color appearances like PerInstanceColorAppearance.
See:
Source: Core/VertexFormat.js, line 115

staticconstantVertexFormat.POSITION_AND_ST :VertexFormat

An immutable vertex format with position and st attributes. This is compatible with EllipsoidSurfaceAppearance.
See:
Source: Core/VertexFormat.js, line 148

staticconstantVertexFormat.POSITION_NORMAL_AND_ST :VertexFormat

An immutable vertex format with position, normal, and st attributes. This is compatible with MaterialAppearance when MaterialAppearance#materialSupport is TEXTURED/code>.
See:
Source: Core/VertexFormat.js, line 132

staticconstantVertexFormat.POSITION_ONLY :VertexFormat

An immutable vertex format with only a position attribute.
See:
Source: Core/VertexFormat.js, line 101

binormal :Boolean

When true, the vertex has a binormal attribute (normalized), which is used for tangent-space effects like bump mapping.

32-bit floating-point. 3 components per attribute.

Default Value: false
Source: Core/VertexFormat.js, line 78

normal :Boolean

When true, the vertex has a normal attribute (normalized), which is commonly used for lighting.

32-bit floating-point. 3 components per attribute.

Default Value: false
Source: Core/VertexFormat.js, line 54

position :Boolean

When true, the vertex has a 3D position attribute.

64-bit floating-point (for precision). 3 components per attribute.

Default Value: false
Source: Core/VertexFormat.js, line 42

st :Boolean

When true, the vertex has a 2D texture coordinate attribute.

32-bit floating-point. 2 components per attribute

Default Value: false
Source: Core/VertexFormat.js, line 66

tangent :Boolean

When true, the vertex has a tangent attribute (normalized), which is used for tangent-space effects like bump mapping.

32-bit floating-point. 3 components per attribute.

Default Value: false
