QCoreApplication::UnicodeUTF8 is deprecated

This enum type used to define the 8-bit encoding of character string arguments to translate(). This enum is now obsolete and UTF-8 will be used in all cases. So remove all instances of QCoreApplication::UnicodeUTF8

Faile to compile in linux, fabs not defined.

Hi, i've just tried to compile in linux and failed, with error "fabs not defined" in file ssaogenerator.cpp. I included cmath in that very same file and works fine. I've seen this in previous issues, is there a reazon why this fix is not included in master?

Show progress bar during map calculation

Looks Promising - But Unbake Diffuse/Albedo Please

Hi,

So far NormalmapGenerator looks promising, but to prevent fighting, it would be helpful to be able to save a diffuse color map.
Thank you for your consideration and effort. : )

Doubt about average calculation in SpecularMap

Hi,
I was looking at the code, and i saw that in specular map, the average calculation was like this:

   double multiplierSum = (redMultiplier + greenMultiplier + blueMultiplier  + alphaMultiplier );
    if(multiplierSum == 0.0)
        multiplierSum = 1.0;
//some other code
    if(mode == IntensityMap::AVERAGE) {
       //take the average out of all selected channels
        intensity = (r + g + b + a) / multiplierSum;
    }

But imho this is not an average, because if every channel has a multiplier of let say 0.1, then the sum is going to be 0.4, and you are going to divide the whole sum by 0.4. Shouldn't the division be the sum of each channel divided by the ammount of channels used?
I really don't know how specular maps are calculated, so it's just a question.. i can fix it if it is a bug.

Build without qt

Hi,

I'd like to have a release based on command line level in order to generate normal maps without the gui. Is that possible?

Thanks!

Every time you press "process queue" a slash is added at the end of the output path.

multipliers instead of checkboxes for channels of normalmaps

make this consistent with the other map generators (spec/disp).

crash on Ubuntu 14.04

(v0.3.2)
On Ubuntu 14.04, as soon as I click on a tab, it's an instant crash with the following error message in the terminal :

./NormalmapGenerator: symbol lookup error: ./NormalmapGenerator: undefined symbol: _ZN7QString13toUtf8_helperERKS_

Preview generated maps in a 3D scene

compilation error

Hi i tried building on manjaro (arch) linux but got errors. I did qmake NormalmapGenerator.pro; make; wit this errors:

Platform independent support (e.g., macOS)

As a Mac user, platform independent support would be extremely helpful!

There is platform independent windowing and graphics API support available such as GLFW and SDL.

Compiling for Linux

Noob question: how do I compile this for debian linux (ubuntu).

Subsurface Scattering Map Generation

Can SubSurface Scattering Maps Be Implemented into this program?

Ideas for 3D preview

This is a collection of ideas and possible features for the 3d_preview branch.

Usability:

• Show a message when OpenGL 4.x is not supported by the system Done: 55e80fe
• Navigating with WASD and moving the light with IJKL is overly complicated in my opinion. I think it would be enough if the user can rotate the cube with the mouse, camera and light don't need to be movable. Done.
• Rename "partition frequency" to "mesh resolution" Done.

Features:

• It should be possible to disable the influence of each map (for example to study only the normalmap influence without any displacement) Done.
• The preview should start when the first map is generated, it should not require all three maps Done.
• I think the background should be black or grey, because currently it doesn't match the lighting in the scene (there's no purple environment light as far as I can tell) Done.
• Smooth shading on the mesh possible?
• Use a shading model like Phong, or even PBR?

Bugs:

• When a new image is loaded, the old maps are still used in the preview (they are only replaced when new maps are generated) Done.
• There are huge differences in lighting between enabled and disabled normalmap, maybe there's a bug in some vector transform? Done.

Use map type selection boxes for normal saving (additional to queue settings)

No DDS

Why there's no support for basic texture format?

Specular to Roughess

Hello
Can you add Invert parameter to Specular map for use it as Roughness map?

Ambient Occlusion map generator

Unnecessary computations

When dropping an image into the preview window, the map for the current window type is computed, then the view switches to the "input image" tab, and when the user goes back to the map that was already computed, it is computed again.

small image + normal map size 10% -> crash

very small white image:

Load the attached image, then set 10% in the "normal map size" and the app will crash
Same thing when doing a queue process with the same 10% parameter
I guess there is a small issue when generated normal map is too small

Normal map is "shifted"

Hello
Thanks for this great project.
I've noticed something weird: the normal map is kind of 'shifted' (few pixels) compared to the real texture.
When light is moving over it, the texture looks like distorted because of that.
