vispy.visuals.collections package#


Module contents#

Collections allow batch rendering of object of the same type:

  • Points

  • Line segments

  • Polylines (paths)

  • Raw Triangles

  • Polygons

Each collection has several modes:

  • raw (point, segment, path, triangle, polygon)

  • agg (point, segment, path, polygon)

  • agg+ (path, polygon)

Note: Storage of shared attributes requires non-clamped textures which is not

the case on all graphic cards. This means such shared attributes must be normalized on CPU and scales back on GPU (in shader code).
