I was wondering if OpenGL crashes a lot. The reason I ask is because my Viper 770 crashes very frequently with OpenGL and almost never with D3D. I thought it was just a driver problem. Sometime later I was talking to my friend about his Voodoo 2 card and he told me that OpenGL crashes more than D3D does. And Please no OpenGL vs. DX wars.

It could be my drivers. When I switch from Diamond''s to nVidia''s drivers, OpenGL is more stable, but the rest of my computer crashes a lot. The only reason I brought up this question is because my friend with the Voodoo 2 had OpenGL problems also.

No API is inherently stable or unstable (though many would disagree with me about the Win32 API =). It''s a matter of the implementation. So it''s up to hardware vendors to provide quality drivers. And only recently have they begun to do just that--get serious about OpenGL support. 3dfx, though, has always provided half-a**ed OpenGL drivers, so saying that someone gets crashes on a Voodoo 2 is no surprise. =)

Many video cards dont have full OpenGL support, and many dont have it at all! Go to the manufactor''s web site (i cant remember who made the Viper 770!), and check to see if OpenGL is fully supported. DirectX usually is, but that''s because Microsoft is so big and they pressure companies to support it, but I wont get into that now.

You could try glsetup. It provides full openGL driver support for most chipsets. If you have a copy of quake3, you already have glsetup. Otherwise, try

I believe Mr. nes8bit's experience is special and limited.

According to my experience, Direct3D is much more unstable than OpenGL.

SlaveZero Demo stopped working on Direct7 and Geforce.
Many Direct3D games freeze with 3dfx boards.

The last problem has been known to some group of programmers. Genesis3D team pointed out the last problem, too.

Anonymous Poster: Diamond made the Viper 770 and it runs the off of the TNT2 chipset
benjamin bunny: I have tried GLSetup and their drivers crash Explorer.
Kate: Experience? comon, I''m 15.

I thought it could be a driver problem in the start. When I heard of the Voodoo 2 crashing a lot more with OpenGL then I thought it could be an API problem. After reading about what merlin9x9 had to say, I now think that OpenGL is just neglected.

Well, I''m a developer and have used opengl and DirectX both. The problem is that the makers of 3D graphic card have just started to support OpenGL. The problem is with the driver of course. About opengl you should know that it is the best 3D API ever made. OpenGL is much mature API then DirectX.

I have a v770 myself, and I''ve never had any OpenGL program crash, with any version of the drivers. My guess would be that the card is conflicting with some other device on your computer. Check IRQs first, that''s a good guess. By the way, in my experience GLSetup has terrible drivers for some cards, especially those based on the TNT2 chipset. The latest drivers from Diamond''s website are very good; they let you customize how OpenGL programs will run (previously only available with DirectX programs). Hope all this helps.

Speaking of Viper cards and OpenGL, I ran GLQuake on a Viper V330! Of course I had to try every damn opengl32.dll file I could find, but I think I ended up with Microsoft''s...

Why not try GLSetup? I found it quite helpful on older cards. http://www.glsetup.com

Thanks Wraith, that is the response I wanted.(not being flamed) I''ll go check out the drivers and my card''s settings.

To everyone here: My friends ATI Rage does not crash in OpenGL on MY COMPUTER so it must be drivers or a conflict.

      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
      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?
