Anyone here familiar with OpenGL? I've had a lot of trouble finding modern openGL guides that actually explain what's going on and don't just 'do this because I said so.'

So I've made a basic shader, an .obj into VBO loader, and a pygame window to view it in.

My shader just gives each vertex of an object a random color, applies a white 'fog' to it the further back into the Z it is, and that's really it.

I'm using
gl_FrontColor = mix(fog_color,gl_Color,fog);
in the vertex shader and
gl_FragColor = gl_Color;
is my entire fragment shader.

My actually drawing is being done here:
glEnableClientState(GL_VERTEX_ARRAY);
glEnableClientState(GL_COLOR_ARRAY);
glVertexPointer( 3, GL_FLOAT, 24, self.vbo )
glColorPointer(3, GL_FLOAT, 24, self.vbo+12 )
glDrawArrays(GL_TRIANGLES, 0, self.vbo.size)


You can see what it looks like. Each face is displayed by the order it is drawn in, not by if it should actually be visible.

Is this because of my shader or the way I'm drawing it?

Not at all, you just need to enable the depth test and add a depth component to the FBO (if you're using one).

Terrible. Improved:

char *strrev(char *str)
{
int len = strlen(str); // strlen doesn't count the \0, my friend
char *out = malloc(len+1); // you need to make space for the \0
for (int i = 0; i < len; i++) {
out[i] = str[len-i-1];
}
out[len] = '\0';
return out;
}

>>52254032
It's not.
You need to glEnable the depthtest (which should be on by default anyway) and have a framebuffer with a depth buffer.

Because that's the convention I chose (and the guy I was replying to).

What you said is reasonable and you actually might be right tho.

>>52254235
That causes gRenderer to be an incomplete type.

For the record, this was originally in the main function and worked fine, but then I moved it to another class and had to pass these values.

Essentially, this is all to get a function in main that calls

gSpriteSheetTexture->render(this->getPosX(), this->getPosY(), gRenderer, &gSpriteClips[1]);

You must be doing something wrong but that should work, I replaced the types with ints just for testing sake but this compiles fine:

void test(int *gSpriteSheetTexture, int *gSpriteClips, int *gRenderer)
{
}

int main(int, const char **)
{
int a = 1; // "gSpriteSheet"
int b[2] = {2, 3}; // gSpriteClips[2]
int *c = new int; // gRenderer
*c = 4;

test(&a, b, c);
delete c;
}


Incomplete type could mean that you're storing a class member of the class type as an object rather than a pointer.

This is wrong:
class A
{
A other;
};


This is correct:
class A
{
A *other;
};

What the fuck did you just fucking say about me, you little bitch? I’ll have you know I graduated top of my class in the Navy Seals, and I’ve been involved in numerous secret raids on Al-Quaeda, and I have over 300 confirmed kills.

I am trained in gorilla warfare and I’m the top sniper in the entire US armed forces. You are nothing to me but just another target. I will wipe you the fuck out with precision the likes of which has never been seen before on this Earth, mark my fucking words.

You think you can get away with saying that shit to me over the Internet? Think again, fucker. As we speak I am contacting my secret network of spies across the USA and your IP is being traced right now so you better prepare for the storm, maggot. The storm that wipes out the pathetic little thing you call your life. You’re fucking dead, kid. I can be anywhere, anytime, and I can kill you in over seven hundred ways, and that’s just with my bare hands.

Not only am I extensively trained in unarmed combat, but I have access to the entire arsenal of the United States Marine Corps and I will use it to its full extent to wipe your miserable ass off the face of the continent, you little shit. If only you could have known what unholy retribution your little “clever” comment was about to bring down upon you, maybe you would have held your fucking tongue.

But you couldn’t, you didn’t, and now you’re paying the price, you goddamn idiot. I will shit fury all over you and you will drown in it.

You’re fucking dead, kiddo.

Ok, tell me if I got this right.
A Vertex Buffer Object is just a collection of data. Typically an array of floats.
A Vertex Attribute specifies how the data in the VBO is organized so that it can be passed on to the vertex shader.
A Vertex Array Object stores VBOs and their Vertex Attributes so that they can be called all at once.

not reliable unless the code downloads all 4chan images and then uses image libraries to compare them, but that's a fuckload of time especially since you can only make 1 json call per second.

OCaml is the language in which the most popular unikernel, Mirage-OS, is programmed. It is also used a lot in the financial industry.
ATS and Clean are research languages. Both are usable in real life, but don't expect libraries. They both offer a lot of very useful features, such as linear and dependent types, functions on proofs, standard features from ML, and very high performance.
