Voxel Rendering

[tefu]

I managed to get a very barebones voxel world up and running.

One small issue though. When you look at voxels from the negative X, Y, or Z directions, voxels that are further away overlap voxels that are closer.

While I work on fixing that, I thought it'd be nice if everyone could see what I have so far.

I do have GLM installed and still can not run cmake with the error above.

on osx I get this error:

[tefu]

Could you tell me what version of GLM you're using? I'm having trouble reproducing the error.

On my Arch Linux box I'm using GLM 0.9.5.4-2, and on my Linux Mint virtual machine I'm using GLM 0.9.5.1-1. Both seem to build fine.

I found this from running dpkg -s libglm-dev on Mint, by the way.

[tefu]

Alright, I made the typedefs dependent on the GLM version. It should work for GLM versions 0.9.4-0.9.6 now. I also fixed the depth issue with OpenGL I was having earlier.

@ksundberg Can you review the pull request again?

[ostlerc]

OSX compiles, but the opengl displays nothing and my mouse is trapped in the middle of the box. Not sure what's happening there. On ubuntu I get string errors, which normally means you need to use the wxT("").

The mouse is supposed to be trapped. I was using that to control the camera, while keeping the mouse in window. You can disable it with ESC.

I'll try getting an Ubuntu VM up and running so I can reproduce your errors.

[ostlerc]

so, everything compiles now and it runs. But both on ubuntu and osx I don't see anything being rendered. I assume this isn't what you're seeing. But I do think there might be something more wrong than just my setup. What is wrong, however, I don't know. I would be interested to know if anyone else is having this issue.

[ksundberg]

So this compiles and passes unit tests for me but the behavior of the application is clearly incorrect. The window is not being drawn, which leads to a number of artifacts on the screen, none of which look like your screen shots. Also switching between the views via the menu causes lock-ups and crashes.

[tefu]

I managed to get an Ubuntu VM in VirtualBox to run the application. Here's what I see now.

I'm not getting crashes, so I don't think this is what you're experiencing. I tried running on an old Arch laptop I had lying around with a much weaker graphics card, and I got the same torn up blocks. Still no crashes. I thought that maybe the application was making assumptions about the host operating system, so I tried running the Ubuntu VM from Windows, and still got the same results. Lowering the problem size doesn't seem to do much.

I'll try playing computer with this over the next few days, provided midterms don't get in the way. I'm sure I'm doing something crazy with OpenGL, but I'm not sure exactly what yet.

[ostlerc]

as a data point, osx still displays nothing as well

[waredavid]

I just looked online and for some reason our most recent pull request got the wrong code a large amount of it has been changed. That might be why things are appearing wrong. I apologize that I did not realize this sooner.

One small issue though. When you look at voxels from the negative X, Y, or Z directions, voxels that are further away overlap voxels that are closer. [image: 2015-02-27-15_24_18] https://cloud.githubusercontent.com/assets/10508654/6422418/a1d350dc-be95-11e4-85e7-2ad20965e362.png

While I work on fixing that, I thought it'd be nice if everyone could see

what I have so far.

[tefu]

a large amount of it has been changed.

If you're referring to ChunkManager, I changed it. Our group added all the graphics capabilities, so I don't think yours could be at fault for the cross-platform issues.

Anyway, updates: I switched to using textures instead of raw colors for the voxels.

Amateur GIMP skills, hurray.

I tested on my Ubuntu VM, but I doubt this will fix the issues of crashing and voxels not appearing, since I haven't been able to reproduce that bug yet. Hopefully our group will have access to an OSX machine soon. Otherwise we'll be stuck blindcoding glEnable's, which is insanity.

[sammywhammy]

Alright, we were able to successfully render the voxels with textures on a mac!

@ksundberg could you review our pull request once more?

[ostlerc]

ubuntu seems to display properly as well now. Did you remove the shortcut keys for the tools menu for a reason?

[tefu]

Did you remove the shortcut keys for the tools menu for a reason?

I just realized we did. I think adding the EVT_KEY_DOWN event to the canvas overrides the main app's shortcut keys. I'll try looking into getting those keys back.

[waredavid]

I can't get this code to run on my Ubuntu VM

[tefu]

Does it not compile, or does the executable just not run? If it's the latter, did the rotating cubes not run for you as well?

[waredavid]

It compiles but when I run the program it crashes. I can run the program with the rotating cubes. On Mar 17, 2015 12:00 PM, "tehul" notifications@github.com wrote:

This draws nothing for me on osx. I do not get a crash however.

[tefu]

Huh, not sure what's going on. There's a lot of OpenGL boilerplate we had to play with to get it working, mostly caused by switching to modern OpenGL. Maybe we missed something necessary. I'll try looking into it.
