VertexFormat

VertexFormat

new

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.

Parameters:
Name Type Argument Default Description
options Object <optional>
undefined 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 VertexFormat({
  position : true,
  st : true
});

Members

: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

: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

:Boolean

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

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

Default Value:
  • false

:Boolean

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

32-bit floating-point. 2 components per attribute

Default Value:
  • false

: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

An immutable vertex format with all well-known attributes: position, normal, st, binormal, and tangent.

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.

An immutable vertex format with position and normal attributes. This is compatible with per-instance color appearances like PerInstanceColorAppearance.
