Greetings everyone,

I'm a little bit confused about the voxel types and would like some help regarding this matter.
What I'm trying to do is the following: let's say I have set a voxel at a location x, y, z, I would like to assign a type for that specific voxel, let's say the type is an int value, so It would be a voxel at x, y, z location with let's say 1 as an int value assigned to it. The purpose of this is to be able to set a per voxel propriety like grass, dirt etc.

So is there an already made implementation into polyvox that allow us to do the following? Like defining an enumeration from let's say 0 to 10, with 0 assigned to grass, 1 assigned to rock and so on, then once we set a voxel we can have the option to specify a type ranging from 0 to 10 for example and save it with that specific voxel, so later on we can access that type and assign whatever propriety we want to that voxel.

I hope my explanation was clear enough thanks.

not sure if i got it right.

you want to set a type (e.g. "grass", "earth") and then, depending on the type set some other value? ("grass" -> "green", "brown", "earth" -> "good soil", "stony")
or do you simply want to set a voxel to an enum?

if it is the latter, that is already possible. just create your enum


and use PolyVox::Material8.



if it is the first one, you will need your own Material implementation (which is not all that difficult to implement)

Thanks Ker, that's what I needed, actually I kinda need this for the two reasons you stated above, my terrain is textured using an auto texture system, it takes the y normal of the voxel surfaces and then depending on the angle value from 0 to 1 it assign a texture, the problem with this implementation is that if I try to add trees for example they will get the same auto texturing. Now if I assign a type to some voxels I can exclude it from my auto texturing process and apply the desired texture and proprieties that I want

EDIT:
SetVoxelAt, isn't the last parameter controlling the density of the voxel?

nope, it is controlling the voxel itself. you will assign the whole voxel.
You can use any c++ object as a voxel type.
so for your case you'll have to create one that has a field for material and one for variation.
you best copy the Material class and add whatever extra stuff you need.
