Arrgh. As a DirectX user i am finding it incredibly annoying why VS.NET cannot find any GL headers, i.e GL/glu.h, GL/glut.h. I am trying to compile some CG code, and even with me adding "glut.h" into the header, it cannot find it! All i get when i try to compile OpenGL code - (take the simple OpenGl tutorial) i get cannot open include file <GL/glut.h> can someone explain what is going on as it is annoying!

OK, i've managed to get simple working, by

b) adding glut.h to the compiler lib
c) specify to include opengl32.lib in the project linker properties

THERE HAS TO BE AN EASIER WAY THAN THIS? Isn't there a general framework that does all this? Theres hundreds of header files and .dll's for OpenGL!

Hmmm, easier way? This is the standard procedure that is used for just about any C++ program using an exernal library. However, OpenGL is just one library that you just need to include one library and one header file for all the functions, so no need to worry. The reason you have trouble with GLUT is because it is not installed by default. I do not think I even have it, so do not worry. You can if you want make your own project template, but you will not be saving that much time. You will only have to copy the .dll's to the system folder on new library installs. Adding in the necessary libs can be done by using the
#pragma comment (lib,"opengl32.lib")
command. I think that should work for .Net, but I am not 100% sure. DirectX library is much bigger than OpenGL, and you only need to include maybe 2 or 3 headers for all the functions. The .DLLs are already there as well. Do you kind of see what I mean?

Hundreds? There are **3**
gl.h
glu.h
glaux.h

if you use glut than it's 4.

that's also 4 libraries : opengl32.lib glu32.lib glaux.lib and glut32.lib :-)

extensions might include 1 or 2 more.

You could write a plugin for VS.NET for a wizard to generate a dummy GLUT or WGL application but really all you need to do is create a template and do a few steps to build a new app from it everytime.

glaux.h is not recognized. Ah well, after further learning apparently GLUT is dated, i am using SDL at the moment.

The thing is, i was trying to compile some CG code, and it required <GL/Glut.h> i added it to the header, but still no luck. I could not find a glut32.dll, any suggestions to make it compile?

Install GLUT?

Very first link on a google search for "glut" (That is a hint to try to search for the answers yourself before asking here).

yea thanks for the smart comment. Perhaps when you dl that file you won't find the glut32.lib which is needed. So yea, i've solved the problem. I just hope when you ask me something about dx or c++ i'm not as rude.

One word (or is it 2?) freeglut...on sourceforge. Its newer....

You're welcome.
The contents of the glut-3.7.6-bin.zip file on that page are...
glut.defglut.hglut32.dllglut32.libREADME-win32.txt

EDIT: By the way, I didn't mean to be rude, it's just that a lot of people who post are too lazy to search for themselves and it gets very annoying pretty quickly. So I apologize if you did search first and for coming off as a smartass (it's hard for me not to sometimes).

a newer version is openglut /a>
Apology accepted, i went to the official glut website, and the zip folder i d/l'ed just contained levery lib possible apart from glut32.lib i.e fglut, gle.n32 etc. But yea, i did find a folder which did have the exact stuff you mentioned.

Nothing, but from my experience, SDL in VC.NET has a lot more to setup than GLUT. If you use GLUT, all you need to do is to include glut.h, then all the required files will be automatically linked.

For SDL, you need to include SDL header file, link to two lib files, and set your project to multithreaded dll. There are also more lines in SDL for setting up a window. But I like SDL better mainly because it has other things than windowing such as joystick support and threads.

• Good Evening,
I want to make a 2D game which involves displaying some debug information. Especially for collision, enemy sights and so on ...
First of I was thinking about all those shapes which I need will need for debugging purposes: circles, rectangles, lines, polygons.
I am really stucked right now because of the fundamental question:
Where do I store my vertices positions for each line (object)? Currently I am not using a model matrix because I am using orthographic projection and set the final position within the VBO. That means that if I add a new line I would have to expand the "points" array and re-upload (recall glBufferData) it every time. The other method would be to use a model matrix and a fixed vbo for a line but it would be also messy to exactly create a line from (0,0) to (100,20) calculating the rotation and scale to make it fit.
If I proceed with option 1 "updating the array each frame" I was thinking of having 4 draw calls every frame for the lines vao, polygons vao and so on.
In addition to that I am planning to use some sort of ECS based architecture. So the other question would be:
Should I treat those debug objects as entities/components?
For me it would make sense to treat them as entities but that's creates a new issue with the previous array approach because it would have for example a transform and render component. A special render component for debug objects (no texture etc) ... For me the transform component is also just a matrix but how would I then define a line?
Treating them as components would'nt be a good idea in my eyes because then I would always need an entity. Well entity is just an id !? So maybe its a component?

Hello. I am coding a small thingy in my spare time. All i want to achieve is to load a heightmap (as the lowest possible walking terrain), some static meshes (elements of the environment) and a dynamic character (meaning i can move, collide with heightmap/static meshes and hold a varying item in a hand ). Got a bunch of questions, or rather problems i can't find solution to myself. Nearly all are deal with graphics/gpu, not the coding part. My c++ is on high enough level.
Let's go:
Heightmap - i obviously want it to be textured, size is hardcoded to 256x256 squares. I can't have one huge texture stretched over entire terrain cause every pixel would be enormous. Thats why i decided to use 2 specified textures. First will be a tileset consisting of 16 square tiles (u v range from 0 to 0.25 for first tile and so on) and second a 256x256 buffer with 0-15 value representing index of the tile from tileset for every heigtmap square. Problem is, how do i blend the edges nicely and make some computationally cheap changes so its not obvious there are only 16 tiles? Is it possible to generate such terrain with some existing program?
Collisions - i want to use bounding sphere and aabb. But should i store them for a model or entity instance? Meaning i have 20 same trees spawned using the same tree model, but every entity got its own transformation (position, scale etc). Storing collision component per instance grats faster access + is precalculated and transformed (takes additional memory, but who cares?), so i stick with this, right? What should i do if object is dynamically rotated? The aabb is no longer aligned and calculating per vertex min/max everytime object rotates/scales is pretty expensive, right?
Drawing aabb - problem similar to above (storing aabb data per instance or model). This time in my opinion per model is enough since every instance also does not have own vertex buffer but uses the shared one (so 20 trees share reference to one tree model). So rendering aabb is about taking the model's aabb, transforming with instance matrix and voila. What about aabb vertex buffer (this is more of a cosmetic question, just curious, bumped onto it in time of writing this). Is it better to make it as 8 points and index buffer (12 lines), or only 2 vertices with min/max x/y/z and having the shaders dynamically generate 6 other vertices and draw the box? Or maybe there should be just ONE 1x1x1 cube box template moved/scaled per entity?
What if one model got a diffuse texture and a normal map, and other has only diffuse? Should i pass some bool flag to shader with that info, or just assume that my game supports only diffuse maps without fancy stuff?
There were several more but i forgot/solved them at time of writing

Hi All,
I'm reading the tutorials from learnOpengl site (nice site) and I'm having a question on the camera (https://learnopengl.com/Getting-started/Camera).
I always saw the camera being manipulated with the lookat, but in tutorial I saw the camera being changed through the MVP arrays, which do not seem to be camera, but rather the scene that changes:
#version 330 core layout (location = 0) in vec3 aPos; layout (location = 1) in vec2 aTexCoord; out vec2 TexCoord; uniform mat4 model; uniform mat4 view; uniform mat4 projection; void main() { gl_Position = projection * view * model * vec4(aPos, 1.0f); TexCoord = vec2(aTexCoord.x, aTexCoord.y); } then, the matrix manipulated:
..... glm::mat4 projection = glm::perspective(glm::radians(fov), (float)SCR_WIDTH / (float)SCR_HEIGHT, 0.1f, 100.0f); ourShader.setMat4("projection", projection); .... glm::mat4 view = glm::lookAt(cameraPos, cameraPos + cameraFront, cameraUp); ourShader.setMat4("view", view); .... model = glm::rotate(model, glm::radians(angle), glm::vec3(1.0f, 0.3f, 0.5f)); ourShader.setMat4("model", model);
So, some doubts:
- Why use it like that?
- Is it okay to manipulate the camera that way?
-in this way, are not the vertex's positions that changes instead of the camera?
- I need to pass MVP to all shaders of object in my scenes ?

What it seems, is that the camera stands still and the scenery that changes...
it's right?

Thank you

• Sampling a floating point texture where the alpha channel holds 4-bytes of packed data into the float. I don't know how to cast the raw memory to treat it as an integer so I can perform bit-shifting operations.

int rgbValue = int(textureSample.w);//4 bytes of data packed as color
// algorithm might not be correct and endianness might need switching.
vec3 extractedData = vec3(  rgbValue & 0xFF000000,  (rgbValue << 8) & 0xFF000000, (rgbValue << 16) & 0xFF000000);
extractedData /= 255.0f;

• While writing a simple renderer using OpenGL, I faced an issue with the glGetUniformLocation function. For some reason, the location is coming to be -1.
Anyone has any idea .. what should I do?
