Member Data Documentation

◆ tile

vgl_tile_id vgl_draw_item::tile

◆ mesh

uint64_t vgl_draw_item::mesh

◆ mesh_handle

uint64_t vgl_draw_item::mesh_handle

As set by vgl_frame_resource_handle_set, or 0.

◆ index_list

uint64_t vgl_draw_item::index_list

◆ index_list_handle

uint64_t vgl_draw_item::index_list_handle

◆ index_count

uint32_t vgl_draw_item::index_count

◆ index_size

uint32_t vgl_draw_item::index_size

2 or 4, as in the index list.

◆ first_layer

uint32_t vgl_draw_item::first_layer

The item's layers in the frame's layer list, bottom first.

◆ layer_count

uint32_t vgl_draw_item::layer_count

◆ model_view

float vgl_draw_item::model_view[16]

Mesh coordinates to camera space, column-major: composed in double precision and rounded to float at the end.

◆ centre

vgl_dvec3 vgl_draw_item::centre

ECEF origin of the mesh coordinates, for consumers that compose their own transforms.

◆ min_height

double vgl_draw_item::min_height

◆ max_height

double vgl_draw_item::max_height

◆ geoid_heights

float vgl_draw_item::geoid_heights[4]

The geoid's height above the ellipsoid at the tile's corners, in metres: north-west, north-east, south-west and south-east. Interpolated bilinearly over the mesh's texture coordinates (u east, v south), it gives mean sea level under each vertex: a vertex's height above mean sea level is its height minus that, and a sea surface lies there. Zero where has_geoid is VGL_FALSE: the context has no geoid pack, or it has not loaded there yet.

◆ has_geoid

vgl_bool vgl_draw_item::has_geoid

◆ reserved

uint32_t vgl_draw_item::reserved
