Detailed Description

This abstract node type is the base type for all node types that specify per-vertex attribute information to the shader.

The name field describes a name that is mapped to the shading language-specific name for describing per-vertex data.

Member Function Documentation

◆ defaultXMLContainerField()

virtual string H3D::X3DVertexAttributeNode::defaultXMLContainerField ( )

inlinevirtual

Returns the default xml containerField attribute value.

For this node it is "attrib".

Reimplemented from H3D::Node.

◆ render()

virtual void H3D::X3DVertexAttributeNode::render ( int )

inlinevirtual

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. The vertex attribute will be rendered as the attribute index specified by the setAttribFunction.

Reimplemented in H3D::Matrix4VertexAttribute, H3D::Matrix3VertexAttribute, and H3D::FloatVertexAttribute.
