This is an X3D element to map a texture to this material. From X3D specification: The ImageTexture node defines a texture map by specifying an image file and general parameters for mapping to geometry. Texture maps are defined in a 2D coordinate system (s, t) that ranges from [0.0, 1.0] in both directions. The bottom edge of the image corresponds to the S-axis of the texture map, and left edge of the image corresponds to the T-axis of the texture map. The lower-left pixel of the image corresponds to s=0, t=0, and the top-right pixel of the image corresponds to s=1, t=1. <!--When fixed: add type="x3d:ImageTexture"-->

Value represents the average value over the preceding interval. more like this
Value represents the average value over the following interval. more like this
Value is constant in the preceding interval.
Value is constant in the succeeding interval.
A continuous time series indicates the observation result is the value of a property at the indicated instant in time. The points are essentially connected and interpolation may occur between points in order to estimate the value of the property between points. The appropriate time spacing between successive points to minimise interpolation errors is related to rate of change (wrt time) of the property.
The sampling of the property occurs such that it is not possible to regard the series as continuous. The time between samples is too large to classify the measurements as continuous.
Value represents a total attributed to a specific time instant. This is normally generated from an event based measuring device such as a tipping bucket rain gauge.
Value represents the maximum value that was measured during the preceding time interval.
Value represents the maximum value for the following interval.
