Purpose

The module SoView2DVectorFieldView overlays an image with vector data (vec2 or vec3) as vector glyphs.

Details

The visualized vectors consist of a midpoint, the vector itself and an arrow tip.

The midpoint can be considered the starting point of the vector and it is placed in the midpoint of a voxel.

The vector part reflects the length and direction of the image value vector. Note that by the optional normalization the length is set to 1 for each vector and the vector's length can additionally be scaled by a single factor.

The arrow tip consists of a triangle at the end tip of the vector, emphasizing the direction of the vector.

If the vector parts are not displayed in fixed mode, all the width and length parameters are evaluated as percent of visible voxel sizes.
