Detailed Description

Represents a sub-mesh, it contains local vertices and triangles.

Vertices and normals have the same size and are linked by id stored in triangles.

Note

uv contains data only if your mesh have textures (by loading it or after calling applyTexture).

Constructor and Destructor

Chunk()

Chunk

(

)

Default constructor which creates an empty Chunk.

~Chunk()

~Chunk

(

)

Chunk destructor.

Functions

clear()

void clear

(

)

Clears all chunk data.

Variables

vertices

std::vector<float3> vertices

Vertices are defined by a 3D point {x,y,z}.

triangles

std::vector<uint3> triangles

Triangles (or faces) contains the index of its three vertices. It corresponds to the 3 vertices of the triangle {v1, v2, v3}.

normals

std::vector<float3> normals

Normals are defined by three components, {nx, ny, nz}. Normals are defined for each vertices.

uv

std::vector<float2> uv

UVs defines the 2D projection of each vertices onto the Texture.
Values are normalized [0;1], starting from the bottom left corner of the texture (as requested by opengl).
In order to display a textured mesh you need to bind the Texture and then draw each triangles by picking its uv values.

Note

Contains data only if your mesh have textures (by loading it or calling applytexture).

timestamp

unsigned long long timestamp

Timestamp of the latest update.

barycenter

float3 barycenter

3D centroid of the chunk.

has_been_updated

bool has_been_updated

True if the chunk has been updated by an inner process.
