Matrix3VertexAttribute

Overview

Matrix3VertexAttribute defines a set of per-vertex 3x3 matrix attributes.

The Matrix3VertexAttribute node belongs to the Shaders component and requires at least level 1, its default container field is attrib. It is available from X3D version 3.0 or higher.

Fields

SFNode [in, out] metadata NULL [X3DMetadataObject]

Information about this node can be contained in a MetadataBoolean, MetadataDouble, MetadataFloat, MetadataInteger, MetadataString or MetadataSet node.

Hint

• X3D Architecture 7.2.4 Metadata

SFString [ ] name “”

Required name for this particular VertexAttribute instance.

Hints

• Well-defined names can simplify design and debugging through improved author understanding.
• X3D Scene Authoring Hints, Naming Conventions

Warning

• name is not specified if this instance is a USE node.

MFMatrix3f [in, out] value [ ] (-∞,∞)

value specifies an arbitrary collection of matrix values that will be passed to the shader as per-vertex information.

Hint

• The length of the value field shall be a multiple of numComponents.
