Hello Benny.
As in video #31 of Java Game Engine Development Tutorial I add line in the fragment shader inside the for loop over the point lights:
if(pointLights[i].base.intensity > 0)
But instead of FPS growth I get no point light drawn in the scene. After the whole day of experiments I've noticed:

• if I compare with some negative constant instead of 0 then all lights are back but if statement seems to be ignored
• if I assign all three attenuation coefficient to non-zero values lights are back as in previous case. If statement is still not working
• out of range check in calcPointLight function works just fine (if(distanceToPoint > pointLight.range) return vec4(0,0,0,0);), so I tried to do the same but with pointLight.base.intensity - no success. If I set some intensity threshold that only one of the lights can pass I still get no lights or all lights drawn.

I can't believe that if statement is not working and not to have this kind of optimization is also not a case. The same is observed in c++ version (Initial Commit). Any ideas?
And some more questions: don't we need to specify in/out/inout parameters for input parameters of the functions as in http://www.opengl.org/wiki/GLSL_:_common_mistakes
And second one: is there any better than:
if (textureColor != vec4(0, 0, 0, 0))
way to check inside the shader if some texture was bound? Because current one can cause artefacts if texture contains black pixels with alpha value equal zero.
Thanks.

I just finished part 20 of this game engine (https://www.youtube.com/watch?v=ShheuoQpJR4) and now I can move the camera but when I rotate it's orientation gets stuck.
I've been following the videos a bit differently (instead of using getters and setters I make most variables public) but apart from being able to use getX(), getY() and getZ() that's not so big of a issue I hope.
Also, I added some minimal debugging so if you press 1 it tells you the camera's position, forward and up vectors.

Video of the issue: https://www.youtube.com/watch?v=Vu5CnmixJEg

Fragment shader extension (fs) is used for F# files. D may cause confusion

I was watching your tutorial and noticed that you created the Input class witch is largely unneeded. You can do the same thing it does more efficiently with

while (Keyboard.next()) {
    char key = Keyboard.getEventCharacter();
    boolean state = Keyboard.getEventKeyState(); // If the key is held down (true) or released (false)
   // TODO: Handle key clicks
}

Another thing to look into is using

int NUM_KEYCODES = Keyboard.getKeyCount();

instead of the current constant.

There are two files where sampling.glh is included. But this file does not exist.
The first call is in lightingMain.fsh on line 1 and the second one is in forward-ambient.fs on line 2. Am i the only one with this problem? Or is there actually a file missing?

Thanks in advance!

When the camera is added as a child of testMesh1, the rotation and position are inherited properly.
When the camera is added as a child of testMesh2, the position is inherited, but rotation is not.
What I mean by this is if I rotate testMesh2 to "face" testMesh1, the camera will not start facing testMesh1, but the movement axes are correct. Code:

testMesh1.getTransform().getPosition().set(0, 2, 0);
testMesh1.getTransform().setRotation(new Quaternion(new Vector3f(0, 1, 0), 3.14159f/2));

testMesh2.getTransform().getPosition().set(0, 0, 10);
testMesh2.getTransform().setRotation(new Quaternion(new Vector3f(0, 1, 0), 3.14159f));

testMesh1.addChild(testMesh2);
testMesh2.addChild(camera);
getRootObject().addChild(testMesh1);

In my program, with the above code, the camera will start at position of testMesh2, but the camera is facing 90 degrees to the left, off the plane, instead of pointing at testMesh1. Even weirder, is the fact that moving forward moves camera toward testMesh1, and the other move axes all correspond to this.

In other words, the camera's move axes are correct, but it is not facing the correct direction, reguardless of the angle given to the second test mesh.

I was following tutorial no.10 and whenever i try to run my code after adding in the parts to load "basicVertex" and "BasicFragment" shaders, I keep getting the error in the title. My code is identical to Benny's.

basicFragment.fs:
#version 330

out vec3 fragColor;

void main()
{
fragColor = vec4(0.0, 1.0, 1.0, 1.0);
}

basicVertex.vs:
#version 330

layout (location = 0) in vec3 position;

void main()
{
gl_Position = vec4(0.25 * position, 1.0);
}

The shaders that you have written should also have an osx compatible version as well.

I can't get the pointlights to work on the plane mesh, it works just fine with the pyramid mesh, could anyone help me out?

Here are the files for my project:
http://ikbenerik.nl/Engine.rar

As i was playing around with loading diffent .obj's i recognized some issues:

Loading without the normals works fine, but if i load normals and texCoords I get some problems with indexing i guess.
So all faces have their own normals. and you can see the single quads.

If I load with texCoords and without normals I get these edges in the reflections.

Laoding with normals and without texCoord does not even work: the texCoord is between the two "/", but if there is none it tries to parse an empty String.

The first two Issues could be caused by me by exporting the obj not properly.
If someone needs Images i can upload some.

Whilst making my own game engine, I realized that GLSL has built-in functions for spot/point lights - it even does some calculations for you, which you can access with derived states. I've been following this tutorial which shows how to implement the Phong reflection model using those functions. I'm not sure how much it may mean for performance, but I don't see a reason why you have to make your own uniforms for those lights.

EDIT: On a side note, GLSL also has structs for materials (which closely mirror the wavefront .mtl file format :3). The only uniforms you'd need to declare on your own are the map samplers.

EDITEDIT: Tonight (in about 8 hours) I'll be committing an example of Phong reflection using those structs and a .mtl loader to my 3D engine repository

Hello, Benny! Many thanks for the your tutorials.

How to fix camera rotation on the Y axis? This is artefact, when up or down rotation.

Before rotate

After rotate

I think this is Camera.rotateX(float angle) method. I changed
forward = forward.rotate(angle, Haxis).normalized();
to
forward = forward.rotate(angle, new Vector3f(1, 0, 0)).normalized();

but this is only slightly reduced the problem. I would be grateful for help.

Just watched episode 52 and saw you using finalize method. There is a rule in java never use finalize because finalize is not guaranteed to be called. Rather use destroy or close ore something like that and handle freeing resources manually.

Hello, Benny.
Not a serious problem but it's the second time (first time it was in Intro to Modern OpenGL series) I see textures rendered upside down. I guess it's because image loaders use coordinate systems with Y-axis pointing down while OpenGL uses up direction for Y texture coordinates. Do you know some easy and efficient way of flipping the image (more interested in c++ version) before we use it as the texture? I know that it can be easily fixed by reassigning texture coordinates but it would be better to stick to general convention. I can think about the most dummy for-loop over all pixels.
Thanks.

I'm using Ubuntu. Is there a web site that has what the tutorial software should look like? I can't seem to be able to output the triangle. Which means I didn't insert a step somewhere. I've looked at the previous tutorials but I cannot seem to locate my error. Help

Hi,
Though I'd try out your engine, builds fine, but core dumps at or near: Texture.cpp 190
s_resourceMap.insert(std::pair<std::string, TextureData*>(fileName, m_textureData));

As importet the project into IDEA it didnt mark src as well src

On some meshes, on only some triangles, the texture coordinates don't seem to stick. I'm doing the Wolf. 3D Clone now with a "finished" version of the engine. I have replaced all of the rendering code with Benny's and something still isn't right. You'll see a screenshot also detailing my problem. Thanks guys for your help!

EDIT: The door is not the only thing I've had occasional problems with but is an example that I know should work.

EDIT2: Tested it with a mesh exported from blender to the same result.
