static mixed voxel::VoxelMesh	(	mixed	meshname,
		mixed	cx,
		mixed	cy,
		mixed	cz
	)			[inline, static]

voxels a mesh, cx,cy,cz is the voxel grid size each mesh part must be closed

static mixed voxel::CalcVoxelGrid	(	mixed	gfx,
		mixed	cx,
		mixed	cy,
		mixed	cz,
		mixed	gridsize
	)			[inline, static]

obsolete, or at least unused voxel-like mesh analysis, used for collision/interesection detection in shipeditor fine grids generated from raw geometry superseeded by shipvoxelgrid.lua TODO : 2d voxel : 1,3, 1,5, 3,1, 3,7, 5,1, 5,7, 7,3, 7,5, *e , e=1/8 -- a circle of points that is not hit by lines on a 1/2 grid returns 3 dimensional array, zero based, [xi][yi][zi] = 0 means outside, = 1 means inside gfx must start at 0,0,0 and not go into negative coords WARNING ! only works on simple (convex) forms

Definition at line 5890 of file lua_pseudo_code.cpp.

static mixed voxel::ForEachVoxel	(	mixed	voxelgrid,
		mixed	fun
	)			[inline, static]

calls fun(voxelstate,x,y,z) with every voxel the process is aborted and returns the first value of what fun returns if it is something other than nil

Definition at line 5894 of file lua_pseudo_code.cpp.

static mixed voxel::TransformVoxelGrid	(	mixed	voxelgrid,
		mixed	px,
		mixed	py,
		mixed	pz,
		mixed	qw,
		mixed	qx,
		mixed	qy,
		mixed	qz,
		mixed	sx,
		mixed	sy,
		mixed	sz,
		mixed	gridsize
	)			[inline, static]

returns a new voxel grid sx,sy,sz should be integers (e.g. mirrors, or scale by two) qw,qx,qy,qz should be an orthogonal rotation (e.g. 90 degrees to the right,...)

Definition at line 5899 of file lua_pseudo_code.cpp.

static mixed voxel::VoxelGridIntersection	(	mixed	voxelgrid1,
		mixed	voxelgrid2
	)			[inline, static]

compares two voxel grids and returns true if they intersect

Definition at line 5902 of file lua_pseudo_code.cpp.

static mixed voxel::DrawVoxelGrid	(	mixed	voxelgrid,
		mixed	parentgfx,
		mixed	gridsize
	)			[inline, static]

creates and returns returns array of (green) billboard gfx for every voxel "inside"

Definition at line 5905 of file lua_pseudo_code.cpp.

static mixed voxel::GfxVoxelLine	(	mixed	gfx,
		mixed	gridsize,
		mixed	numcells,
		mixed	rx,
		mixed	ry,
		mixed	rz,
		mixed	rvx,
		mixed	rvy,
		mixed	rvz
	)			[inline, static]

ray must be padded with gridsize at the start and at the end to avoid rounding errors returns voxel-cells along ray, arr[zi] (where 0 <= zi < numcells) (2 means border, 0 means outside, 1 means inside)
