org.oscim.utils.pool.Inlist<MapTile.TileData>

org.oscim.layers.tile.MapTile.TileData

org.oscim.renderer.bucket.RenderBuckets

public class RenderBuckets
extends MapTile.TileData

This class is primarily intended for rendering the vector elements of a MapTile. It can be used for other purposes as well but some optimizations (and limitations) probably wont make sense in different contexts.

Field Detail

VERTEX_CNT

public static final int[] VERTEX_CNT

SHORT_BYTES

public static final int SHORT_BYTES

Constant Field Values

vbo

public BufferObject vbo

VBO holds all vertex data to draw lines and polygons after compilation. Layout: 16 bytes fill coordinates, n bytes polygon vertices, m bytes lines vertices ...

ibo

public BufferObject ibo

offset

public int[] offset

To not need to switch VertexAttribPointer positions all the time: 1. polygons are packed in VBO at offset 0 2. lines afterwards at lineOffset 3. other buckets keep their byte offset in offset
