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).
