NAME

SG_Voxel — Agar-SG voxel object

SYNOPSIS

#include <agar/core.h>
#include <agar/sg.h>

DESCRIPTION

The SG_Voxel node renders a three-dimensional array of real-valued "cells".

INHERITANCE HIERARCHY

AG_Object(3) -> SG_Node(3) -> SG_Voxel.

INITIALIZATION

SG_Voxel *
SG_VoxelNew(SG_Node *parent, const char *name);

void
SG_VoxelAlloc3(SG_Voxel *vol, Uint width, Uint height, Uint depth);

int
SG_VoxelSet3(SG_Voxel *vol, int x, int y, int z, M_Real value);

void
SG_VoxelReset3(SG_Voxel *vol, M_Real value);

The SG_VoxelNew() function creates a new voxel object at the origin of the parent node.

SG_VoxelAlloc3() allocates a voxel of specified dimensions.

SG_VoxelSet3() sets the value of the cell at coordinates x, y, z to the specified value. Returns 0 on success, -1 if the coordinates are invalid.

The SG_VoxelReset3() function resets the value of all cells to the specified value.

STRUCTURE DATA

For the SG_Voxel object:

M_Real ***map

Three-dimensional array of cell values.

int w

Total width.

int h

Total height.

int d
