Detailed Description
The FloatVertexAttribute node defines a set of per-vertex single precision floating point attributes.
The numComponents field specifies how many consecutive floating point values should be grouped together per vertex. The length of the value field shall be a multiple of numComponents.
The value field specifies an arbitrary collection of floating point values that will be passed to the shader as per-vertex information.
Examples:

virtual |
Perform the OpenGL commands to set the vertex attribute with the given index.
value_index is the index of the value in the value field that is to be used.
Reimplemented from H3D::X3DVertexAttributeNode.
