Procedural creation #178

Open MrTopom opened 7 years ago

MrTopom commented 7 years ago

As I need it for my current project, I just initiate an issue related to this aspect.

I have to create different geometric objects of different sizes AND have some meta information extracted from the generation (Bounding box, surface perimeter...).

Sample ideas:

Description

box sx:10, sy:10, sz:20, id: base meta-data src:base data:top-face

VoxelShop Activity

load-desc base.desc save models/base.vsd export target-dir/base.dae save-meta target-dir/base.meta.txt

would create a base.vsd file, the corresponding dae file and also the meta-information. Directly in the Unity directory.

The idea is to provide a set a simple command for usually thinks to do.

Sample 1: Provide some different roofs like here https://cdn-business.discourse.org/uploads/stonehearth/_optimized/1d7/9f2/1257bc33c63_690x417.png

Selecting the perimeter of your top face house you could then generate a roof from different roofs set.

Sample 2: Generate Castle or house with typical architecture aspect

Change some voxels colors randomly (pseudo to get the same from one generation to the next one)
Create windows/Doors with elements around
Generate the building walls from base perimeter and extrusion
...

Sample 3: Generate Some island/mountains/sea

Sample 4: In a model, define some water source and then add the voxels for the falling water.

So my initial idea is this: You select the shape tool and a "variation". You then drag an area and it fills the area according to the variation. Variations are math formulas as described here: https://github.com/simlu/voxelshop/issues/43#issuecomment-258135187

This will be implemented as part of https://github.com/simlu/voxelshop/issues/43

Once that is done we will revisit what still needs to be done.

There are actually two tasks in here. One is the procedural creation and the other is exporting.

MrTopom commented 7 years ago

Procedural is different from tools.

Tools allow interaction with the model in the scene by adding voxels.
Behavior of tools is manage by an algorithm/variation who does the real voxel activity.
Procedural generation use those behaviors to create things.

So there is development to create new tools, based on new behaviors and on the other side create a procedural format/tiny language to be able to use those behaviors.

simlu commented 7 years ago

Yes, but the shape tool will use the "tiny programs". And a "procedural generation" is just a tool flavor with a different "tiny program" (algorithm).
