Building

The building system uses scons. You can compile in debug with 'scons', and in release with 'scons mode=release'. On Windows, currently possible to build with msys2 or try prebuilt goxel package directly. The code is in C99, using some gnu extensions, so it does not compile with msvc.

Linux/BSD

Install dependencies using your package manager. On Debian/Ubuntu:

- scons
- pkg-config
- libglfw3-dev
- libgtk-3-dev

Then to build, run the command:

make release

Windows

You need to install msys2 mingw, and the following packages:

pacman -S mingw-w64-x86_64-gcc
pacman -S mingw-w64-x86_64-glfw
pacman -S mingw-w64-x86_64-libtre-git
pacman -S scons
pacman -S make

Then to build:

make release

goxel's Issues

Procedural rendering language documentation

I see the feature as the most interesting part of this software, but unfortunately I haven't found any description of the language used and it's features. Any plans to document it?

Import .vox bug

Goxel is fantastic, but the import of the .vox models MagicaVoxel does not work and creates the tool crashes.

The last commit back to two months ago, do not give up this gem!

I would like to work together, even if you are not a programmer. My email: [email protected] If a tester is useful I can do it willingly.

There is a forum, and the only contact is twitter (not use), so I had no other way to contact you guys. Thanks for your attention.

Greetings.

Export resolution cant be typed in

When I try to type-in exact width & height resolution values, it doesn't work. After setting value and hitting enter, value stays the same and cursor in the field keeps on blinking. So currently only way to edit values is by using arrow buttons (at least on my machines, both OSX Yosemite).

Procedural object does not appear until i switch to brush tool goxel 0.7

after placing a procedural object i have to switch to the brush tool before it arrears. the code will run until completion but nothing will appear until i switch to the brush tool. if i switch before the code has finished i get a snapshot of its current progress at witch point i have to change to some other tool and then change back to the brush to see it update.
This has occurred on 3 different computers for me 2 running windows 10 one running windows 7.

goxel does not load procedural generated objects

after placing an procedural object the code runs but nothing will appear unitll you select the brush tool.at which point all generated voxels pop into existence. If you switch to the brush while the code is running you get a snapshot of what has been generated and you must switch to some other tool and then back to update it.
i have tested this on three separate computers 2 running windows 10 1 running windows 7, one of the windows 10 computers was AMD the other 2 Intel.

.gox file format specifications

Great program!

Do you have any plans to release the .gox file format specifications?

Work for iOS?

Has anyone compiled this sucessfully for the iPad / iOS?

Thanks!

Enhance procedural tools with WaveFunctionCollapse

Here is link to project:
https://github.com/mxgmn/WaveFunctionCollapse

As you can see in part titled "Higher dimensions", that code can be also used for voxels.
Results look very organic. It would be huge to have something like this to generate environments or other big structures.
I imagine that it could work this way: user select layer(s) as input data, configure variables in script (like target volume), run script to generate voxels

[Feature request] Export to .kvx

Use case: creation of voxel models for GZDoom mods

Input is extremely fast.

All input has effect exceedingly quickly, just a half second tap of the left arrow will move the pointer in the code box about 20-30 characters worth of code left. the same happens when rotating the view with key presses or trying to change the the values in boxes by clicking buttons on either side, a half second will change most from negative 1 to positive 1.

Image plane import minor issue

Imported image plane can't be removed or replaced by other image file. Each image import, adds image to existing ones. That causes distortions and flickering while moving camera.

IMHO Image Plane would be more useful with option to turn off smoothing. Now it looks out of place when used as a ground for model. Using it as a reference for drawing model is also hard because of blurriness.

Support importing/exporting Voxlap format (.vxl and .kv6)

It should be great to allow importing/exporting files used by the games Ace of Spades/OpenSpades (which use the Voxlap engine).

The map files (*.vxl) might be too large for editing in Goxel (they are actually describing a volume of 512x512x64 voxels).

But the models files (*.kv6) are already editable with VoxelShop. Supporting this format in Goxel should be great !

More strict compiler on linux got errors

When compiling, I had error about misleading indentation in ext_src/stb/stb_image.h. This is not a real error, but it's pretty obvious : in this file, you use defines to create case with "for" clause with one line instruction, but the compiler can't figure it out with the combine case-for and the last break instruction in the same line.

I corrected the file by adding brackets around the single instruction for the "for" instruction.
There is three block of these:

• line 1360
• line 4090
• line 4100

Improve building documentation

For ubuntu I need to install mesa-common-dev package.
And then follow

On Archlinux, ASan runtime does not come first.

When I try to run, The program die with this error :

==9523==ASan runtime does not come first in initial library list; you should either link runtime to your application or manually preload it with LD_PRELOAD.

I'me on a up-to-date Archlinux.

Increase max resolution of exported image

Talking about export, would it be very time consuming to increase max export resolution from 2048x2048 to 4096x4096? Higher resolution gives very nice edges without need for antialiasing, and gives more flexibility when i.e. editing assets for non-3D animation.

Single-tab Problem for Macbook Pro

In my macbook, you can tap or physically press the click on touchpad. Even thought my single-tab is interpreted as a physical click, the application is not listening that gesture. I had to physically click in my touchpad.

Great app by the way.

Indication of selection size & move tool modes

Now, there is no way to tell what is exact size of selection. It is not a big deal, until something precise needs to be done. Now I'm trying to cut my model into smaller pieces of same sizes, to make tiles out of them. It is doable by counting voxels on screen, but eyes hurt and time is wasted :)

I got few suggestions that could improve Goxel workflow not only in this particular case.
I think right bottom corner could be used for showing size (or other currently affected) values, as You can see on this crude mockup:

Move tool modes - current move tool moves content of whole layer (move: layer content). Two more modes would be very useful. 'Move: selection content' - moves selection box & voxels inside of it. 'Move: selection box' - moves just selection box.

Moving selection by distance that is same as it's size (shortcut maybe? extra setting in move tool, 'move by size iterations'?). Like here selection size is 64 voxels, so selection goes to next adjacent region on selected axis:

Completion of error handling

Would you like to add more error handling for return values from functions like the following?

• calloc ⇒ image_new
• fseek ⇒ read_file

Can't import Color material in Unity3D

Hi, I made a simple map using goxel and exported as .obj file but when I import the file in Unity3D the colors of the map which I used inside goxel editor did not imported in Unity.

Window focus not placing voxel

When the editor window is not focused and I click into the working area to focus goxel, I instantly paint a voxel. Would be great if the application would only paint when it's already focused.

Ctrl-S shortcut does not save file on Windows version

The Ctrl-S keyboard shortcut does not save the file on the latest Windows build (0.4.0). The menu save feature works as expected.

Thanks.

Support of colour palettes in .ase format

Adobe ASE format is common for exchange palettes between graphic design apps and colour palette creation software. Support for loading ASE files would improve colour management in Goxel.
Maybe there could be 'Palettes' folder, from which Goxel would load all ASE palettes and add them to ones that are built-in.
Here are materials that might be useful while evaluating and (maybe) implementing this feature:

Goxel makes corrupted vxls

Hello.
First of all, thank you for making such a great voxel editor ;)

But I noticed an issue :
Exporting .gox with 63-block height to .vxl makes corrupted files, while 62-block height file are exported sucessfully. VXL supports up to 63 blocks, so It should be fine.

Here's my .gox file and its output .vxl file :
Source.zip

I used goxel 0.6 on Windows 10 Pro x64.

reserved identifier violation

I would like to point out that identifiers like "_BOX_H_" and "_GOXEL_H_" do not fit to the expected naming convention of the C++ language standard.
Would you like to adjust your selection for unique names?

Immediately after checking the "see back" box under advanced render settings, the application crashes with this message:

The obj Export does not seem to work correctly, it looks somewhat distorted after importing it in e.g. Unity. Did not yet look into the exporting so I can not give you any Details on it, but i will as soon as I find the time.

Magica Voxel format not OK

Tried to generate some structure and export it to Magica Voxel but the resulting .vox file is not being opened in Magica Voxel.
Went back to just actually saving one block and had a look at the binary format - that seemed quite different. I don't know much about the format specs so I can't give a lot more information.

Bottom line - the export to magica voxel is not really working.

Cheers

P.S.: LOVE the procedural generative part!!! Still addicted to Structure Synth and that is as close as it gets!!

Export as layered BMP

That is, a sprite sheet where each sprite represents a layer. This is possible through vox2png and gimp, but it would be easier if it was possible to do directly in goxel.

./goxel (almost always) segfaults upon launching

I'm on Linux Mint 17.3 KDE. I built from source with make release, but now every time I launch:
[1] 11525 segmentation fault ./goxel
The '11525' in that error increments every time I try to execute, usually by about 10 or 15.
Once, it launched successfully, but I've tried dozens of times and it hasn't stayed open for more than a fraction of a second.

Add LICENSE file

Right now the individual source files in src/ have a proper GPLv3+ license notice but there is no copy of the license in the repository, which means that files that don't have the license notices (like images) could be considered proprietary by some people (even if the README is pretty clear).

A copy of the GPLv3 should be included in a file called LICENSE or COPYING. Here is the text of the license: https://www.gnu.org/licenses/gpl-3.0.txt

text is TINY on hi-dpi monitors

Could you add an option for font size? On a hi-dpi monitor, the UI text looks like grains of dust :)

For comparison, in my own apps, I use 28 as the size for Roboto on hidpi, and 20 as the size for a smaller font for use in tooltips and the like.

goxel 0.7 crashes when pressing the "show desktop" button.

when i press the show desktop button in the bottom right hand corner of my screen goxel will crash.
I have tested this on two computers one running windows 7 another running windows 10, one intel the other amd. it occurs on both.

Linux build issues

I don't know anything about scons so I can't patch it, but here's what I had to do to compile this on x86-64 openSUSE 13.2:

• First I had to change LIBS variable to use glfw3 instead of glfw.
• Then there were a lot of "undefined symbol" errors, to fix them I had to pass these to the C compiler: -lX11 -lXxf86vm -lXi -lXinerama -lXcursor -lXrandr.

Since I don't know scons, I had to manually run the failed command with those extra arguments.

Ray tracing rendering

I'd like to support rendering the scene using a simple raytracer.
Maybe I can use https://github.com/xelatihy/yocto-gl for that?

More shortcuts for switching between tools etc.

I wonder if there is any plans for keyboard shortcuts for switching between tools, changing the view, changing between tabs etc. Because it seems pretty important for usability at an early stage.

Thank you.

Precise camera positioning & camera position(s) saving

Something that all voxel editing tools that I know of are lacking, possibility to precisely set camera position, save it & get back to it when needed. Being able to save multiple camera positions would be even better.

Sometimes I find "perfect view" for rendering a model. But then I notice I have to change something, so I zoom in, rotate, edit, then I try again to find view that I liked in the beginning...it is obviously never the same. It is also impossible to make few variations of same model with exactly same camera position.
Another situation that begs for precise camera, exporting frames for full rotation animation i.e. every 45 degrees.

Someone might say this is unnecessary, because I could export my model to other program. But then
I loose all nice stylization options of Goxel (like awesome 'smooth' mode), so I think it is worth considering.

Per layer transparency

Having separate transparency per layer would open a lot options. I see countless use cases for illustration and some more for game dev (i.e. preview of semi-transparent elements like windows without exporting model to Unity). Many effects normally requiring specialised rendering options - like materials - could be achieved just by smart use of this feature. Smoke, clouds, water, fire, crystals, semi-transparent textiles on characters... lots of possibilities bringing more life into image just by combining few layers with different transparency settings. This could be another feature - among few existing - making Goxel stand out positively among other voxel editors.

Keeping model matrix structure after import/export of .QB format

I hope that at some point in the future Goxel can import each Qubicle matrix as separate layer and the other way around, export each layer to separate matrix while saving to QB format.

Thanks in advance!

AZERTY support

Great software ! Pretty useful.

However, just so you know, AZERTY is not supported and we have to hit (CTRL+W) (which equals CTRL+Z i guess) for undo.

I guess all the other key combination have the same problem.

Good work though !

A single question

Hey there! First off, thank you for creating this wonderful software, this is exactly what I was looking for for developing a "Cube World"-like game in which I needed a voxel based software to easily paint terrains etc manually.

I was wondering how did you achieve not having a voxel scene limit. Both Qubicle and MagicaVoxel have a limit in their matrices, they weren't allowing me to paint big environments from scratch, they're only good enough to create single models and animations.

How did you achieve that? And in which point will the software start to perform badly when handling huge scenes?

Mac OS build has no executable flag on Contents/MacOS/goxel

Zip file in Mac OS build v0.2.0 has -rw-r--r-- permissions (no executable flag) on Contents/MacOS/goxel so app fails to start:

(Workaround to start it: chmod +x /Applications/goxel.app/Contents/MacOS/goxel)

Freezing while drawing with pen tool with snap on mesh but not plane

• Start goxel
• Draw something with pen tool
• Turn off snapping on plane (leave snapping on mesh on)
• Draw something
• It freezes (using 100% cpu while frozen)

For me, reproducible always both in v0.2.0 and master(7e91957). Mac os 10.11.3.

support kv6

would be cool if it supported kv6 files

Better looking user interface

I need to cleanup the current UI, find better icons, font, etc.
