How do I link glut to my application? To link Opengl, I simply put OpenGL32.lib , but how do I link it to GLUT? Programming::~Fredric(const Annoy_Ance)

You need to link agains glut32.lib in Windows. (And have glut32.dll as well.) If you don''t have it chances are you need to download it off the SGI site.

Aw cripes... I guess I don''t have it! :p where can I download it?!

I think this will get you to the glut site:

Yay, I downloaded the files necessary, and put glut.lib, glut.dll, glut32lib, and glut32.dll in the lib section of my VC++ 6.0 files. However, I keep getting 2 errors when I try to build my project. How do I link a dll? I reckon that''s my problem...

It might help if you mentioned the two errors. But generally you need to explicitly specify the glut32.lib as a library to be linked in your link step. In Visual C++ it''s part of project properties under linker.

Yah, I already linked the glut32.lib, but how do I link the .dll seeing as you said that I need to include the dll as well?

Just stick the dlls into the same directory as the executable.

Linking against the dll is done at run-time by the OS (hence the term dynamic link library). You just need to put the dll where the OS can find it. The same directory as the executable will work and so will the windows\system directory. There are a couple of other places that the OS will search too, but I can''t remember them off the top of my head.

Okay, here is where I stand:
I put the glut32.dll in the exact same place as where my .exe would be, but I get the following message:

LINK : fatal error LNK1104: cannot open file "glut32.dll"
Error executing link.exe.

The same place where I stuck opengl32.lib and glut32.lib, I have the glut32.dll (the linker), but I''m still having problems. Can anyone help me even more? I''m new to OpenGL- pity me!

You do not need to link your program against the dll''s neither against glut.lib.

All you need is glut32.lib and opengl32.lib and perhaps glu32.lib. Be sure to have only those specified in your project.

The dll''s are only needed at runtime, not link time.

Okay.. I''ve really *ucked something up here, because now I can''t compile ANY OpenGL applications using the simple OpenGL32.lib and Glaux.lib... this is screwed!!! GRRRR

Okay.. since I put in glut.lib and glut32.lib in the LIB folder of my VC++ 6.0 folder, I can''t even build this:

#include // Standard Window header required

#include ''conio.h'' // Console I/O functions
#include ''gl\gl.h'' // OpenGL functions
#include ''gl\glaux.h'' // AUX Library functions

void main(void)
{
// These are the AUX functions to
auxInitDisplayMode(AUX_SINGLE / AUX_RGBA);
auxInitPosition(100,100,250,250);
auxInitWindow("My first OpenGL Program");

// Colors and Crap
glClearColor(0.0f, 0.0f, 1.0f, 1.0f); // red, green, blue, alpha
glClear(GL_COLOR_BUFFER_BIT);

glFlush();

// Stop and wait for a keypress
cprintf("Press any key to close the Window\n");
getch();
}

This is very frustrating for a beginner OpenGL programmer... since I download glut32.lib and put it in the LIB folder, it''s messed compiling and building up completley! PLEASE, SOMEONE HELP ME!

Is the version of glut32.lib you have for the Microsoft or the Borland compiler? They are different -- if it isn''t this, then I don''t know whats wrong

I really don''t have any idea what version it is... but if I uninstall the compiler, then reinstall it, do you think that''ll flush out all of the bad stuff? (make it work again)

      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?
      Regards,

      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
      Thanks in advance

      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:
      Vertex Shader:
      #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?
