I'm excited about ARB_Sparse_Texture, though I'm a little confused as to why they don't support any of the 3-component texture formats.

Not a very interesting revision, but the new extensions (sparse texture, bindless texture) are intriguing...

Well, since I didn't saw any thread about it, here it is:

 

OpenGL 4.4 released.

 

OpenGL registry where you can see the pdfs of the spec.

 

And nVidia's drivers for it (Linux/Windows/x86/x86_64/yaddayadda). There are a few new extensions also available for OpenGL 3 hardware.

 

Thanks for the heads up.  I'll have to check it out.

I think the biggest improvement is the conformace test. From what i head from who prefer DX over GL is that the drivers sometimes have different behaviours for different cards (with openGL). With this change, all the driver will(?should?) have the same behaviour, making it easier to develop openGL programs.

So, OpenGL 4.4 specs have been published, and AMD still doesn't have a working implementation of OpenGL 4.3. This is wonderful. rolleyes.gif

GPU hardware hasn't supported 3-component texture formats for a long time (aside from packed formats like DXT1).

If you ask GL to give you an RGB texture, on the GPU it will allocate an RGBA texture and pretend that the alpha channel doesn't exit...

Yeah that's something that I always have a whinge about, so this makes me very happy biggrin.png

[the ARB] has created the first set of formal OpenGL conformance tests since OpenGL 2.0 [and] full certification is mandatory for OpenGL 4.4 and onwards

Not gonna comment on the features since I'm still trying to play catch up (this is what happens when you live in a place where any upgrade to a PC ends up costing an entire salary, let alone getting a new computer that isn't already outdated).

 

I'm curious about the certification part, though. Yeah, sure, having a guarantee that drivers always work the same is nice, but how do they plan to enforce it? Does this mean it'll be outright illegal to release an OpenGL driver that isn't certified? I can see that being a massive issue for FOSS drivers (which does matter on Linux). Does anybody have exact details on what certification allows?

 

EDIT: should have checked more carefully

http://www.khronos.org/conformance/

 

OK, it's mostly a trademark issue (so e.g. Mesa probably still would be safe since it doesn't call itself OpenGL). It seems that FOSS implementations still would be able to go through the implementers program if they want to use the name (not the adopters one due to the fee).

Well, AMD is much less of an issue than Intel, they (AMD) are actually pretty good nowadays. Intel is the real problem. They not only do not have a working implementation of OpenGL 4.0, but they also do not have a working implementation of OpenGL 3.0.

 

Which makes me wonder what this entire certification thing will be good for at all.

 

Intel will not pull functional 3.0 (let's not even imagine 4.4) drivers out of their magic hat, but Intel integrated GPUs are the main GPU in every El Cheapo computer, and in the major share of non-tablet computers anyway, too. And, outside the world of Android, they're pretty much omni-present in tablets as well.

 

Which will probably mean no more and no less than OpenGL will simply not be supported (or supported even worse as it is now) on a considerable share of hardware. Sorry for being pessimistic, but I just can't see Intel producing a quality 4.x driver and undergo certification any time soon. They'll just show everyone the middle finger, knowing their CPUs are sold anyway.

 I really don't consider Intel to be that big of any issue. Their integrated graphics are in a completely different class compared to AMD and Nvidia's dedicated GPUs. I mean whats the real advantage to being able to enable the latest OpenGL 4 / DX11 level features in a game if its going to run at 5fps?

      Hi everyone,
      I would need some assistance from anyone who has a similar experience
      or a nice idea!
      I have created a skybox (as cube) and now I need to add a floor/ground.
      The skybox is created from cubemap and initially it was infinite.
      Now it is finite with a specific size. The floor is a quad in the middle
      of the skybox, like a horizon.
      I have two problems:
      When moving the skybox upwards or downwards, I need to
      sample from points even above the horizon while sampling
      from the botton at the same time.  I am trying to create a seamless blending of the texture
      at the points of the horizon, when the quad is connected
      to the skybox. However, I get skew effects. Does anybody has done sth similar?
      Is there any good practice?
      Thanks everyone!

      I'm trying to implement PBR into my simple OpenGL renderer and trying to use multiple lighting passes, I'm using one pass per light for rendering as follow:
      1- First pass = depth
      2- Second pass = ambient
      3- [3 .. n] for all the lights in the scene.
      I'm using the blending function glBlendFunc(GL_ONE, GL_ONE) for passes [3..n], and i'm doing a Gamma Correction at the end of each fragment shader.
      But i still have a problem with the output image it just looks noisy specially when i'm using texture maps.
      Is there anything wrong with those steps or is there any improvement to this process?

      Hello Everyone!
      I'm learning openGL, and currently i'm making a simple 2D game engine to test what I've learn so far.  In order to not say to much, i made a video in which i'm showing you the behavior of the rendering.
      Video: 
       
      What i was expecting to happen, was the player moving around. When i render only the player, he moves as i would expect. When i add a second Sprite object, instead of the Player, this new sprite object is moving and finally if i add a third Sprite object the third one is moving. And the weird think is that i'm transforming the Vertices of the Player so why the transformation is being applied somewhere else?
       
      Take a look at my code:
      Sprite Class
      (You mostly need to see the Constructor, the Render Method and the Move Method)
      #include "Brain.h" #include <glm/gtc/matrix_transform.hpp> #include <vector> struct Sprite::Implementation { //Position. struct pos pos; //Tag. std::string tag; //Texture.

Sprite::Implementation::~Implementation() { delete texture; delete vao; delete vbo; delete layout; delete ibo; delete program; }  
      Renderer Class
      #include "Renderer.h" #include "Error.h" Renderer::Renderer() { } Renderer::~Renderer() { } void Renderer::Draw(VertexArray * vao, IndexBuffer * ibo, Texture *texture, Shader * program) { vao->Bind(); ibo->Bind(); program->Bind(); if (texture != NULL) texture->Bind(); GLCall(glDrawElements(GL_TRIANGLES, ibo->GetCount(), GL_UNSIGNED_INT, NULL)); } void Renderer::Clear(float r, float g, float b) { GLCall(glClearColor(r, g, b, 1.0)); GLCall(glClear(GL_COLOR_BUFFER_BIT)); } void Renderer::Update(GLFWwindow *window) { /* Swap front and back buffers */ glfwSwapBuffers(window); /* Poll for and process events */ glfwPollEvents(); }  
      Shader Code
      #shader vertex #version 330 core layout(location = 0) in vec4 aPos; layout(location = 1) in vec2 aTexCoord; out vec2 t_TexCoord; uniform mat4 u_MVP; void main() { gl_Position = u_MVP * aPos; t_TexCoord = aTexCoord; } #shader fragment #version 330 core out vec4 aColor; in vec2 t_TexCoord; uniform sampler2D u_Texture; void main() { aColor = texture(u_Texture, t_TexCoord); } Also i'm pretty sure that every time i'm hitting the up, down, left and right arrows on the keyboard, i'm changing the model Matrix of the Player and not the others.

      Hello fellow programmers,
      For a couple of days now i've decided to build my own planet renderer just to see how floating point precision issues
      can be tackled. As you probably imagine, i've quickly faced FPP issues when trying to render absurdly large planets.
       
      I have used the classical quadtree LOD approach;
      I've generated my grids with 33 vertices, (x: -1 to 1, y: -1 to 1, z = 0).
      Each grid is managed by a TerrainNode class that, depending on the side it represents (top, bottom, left right, front, back),
      creates a special rotation-translation matrix that moves and rotates the grid away from the origin so that when i finally
      normalize all the vertices on my vertex shader i can get a perfect sphere.
      T = glm::translate(glm::dmat4(1.0), glm::dvec3(0.0, 0.0, 1.0)); R = glm::rotate(glm::dmat4(1.0), glm::radians(180.0), glm::dvec3(1.0, 0.0, 0.0)); sides[0] = new TerrainNode(1.0, radius, T * R, glm::dvec2(0.0, 0.0), new TerrainTile(1.0, SIDE_FRONT)); T = glm::translate(glm::dmat4(1.0), glm::dvec3(0.0, 0.0, -1.0)); R = glm::rotate(glm::dmat4(1.0), glm::radians(0.0), glm::dvec3(1.0, 0.0, 0.0)); sides[1] = new TerrainNode(1.0, radius, R * T, glm::dvec2(0.0, 0.0), new TerrainTile(1.0, SIDE_BACK)); // So on and so forth for the rest of the sides As you can see, for the front side grid, i rotate it 180 degrees to make it face the camera and push it towards the eye;
      the back side is handled almost the same way only that i don't need to rotate it but simply push it away from the eye.
      The same technique is applied for the rest of the faces (obviously, with the proper rotations / translations).
      The matrix that result from the multiplication of R and T (in that particular order) is send to my vertex shader as `r_Grid'.
      // spherify vec3 V = normalize((r_Grid * vec4(r_Vertex, 1.0)).xyz); gl_Position = r_ModelViewProjection * vec4(V, 1.0); The `r_ModelViewProjection' matrix is generated on the CPU in this manner.
      // No the most efficient way, but it works. glm::dmat4 Camera::getMatrix() { // Create the view matrix // Roll, Yaw and Pitch are all quaternions. glm::dmat4 View = glm::toMat4(Roll) * glm::toMat4(Pitch) * glm::toMat4(Yaw); // The model matrix is generated by translating in the oposite direction of the camera. glm::dmat4 Model = glm::translate(glm::dmat4(1.0), -Position); // Projection = glm::perspective(fovY, aspect, zNear, zFar); // zNear = 0.1, zFar = 1.0995116e12 return Projection * View * Model; } I managed to get rid of z-fighting by using a technique called Logarithmic Depth Buffer described in this article; it works amazingly well, no z-fighting at all, at least not visible.
      Each frame i'm rendering each node by sending the generated matrices this way.
      // set the r_ModelViewProjection uniform // Sneak in the mRadiusMatrix which is a matrix that contains the radius of my planet. Shader::setUniform(0, Camera::getInstance()->getMatrix() * mRadiusMatrix); // set the r_Grid matrix uniform i created earlier. Shader::setUniform(1, r_Grid); grid->render(); My planet's radius is around 6400000.0 units, absurdly large, but that's what i really want to achieve;
      Everything works well, the node's split and merge as you'd expect, however whenever i get close to the surface
      of the planet the rounding errors start to kick in giving me that lovely stairs effect.
      I've read that if i could render each grid relative to the camera i could get better precision on the surface, effectively
      getting rid of those rounding errors.
       
      My question is how can i achieve this relative to camera rendering in my scenario here?
      I know that i have to do most of the work on the CPU with double, and that's exactly what i'm doing.
      I only use double on the CPU side where i also do most of the matrix multiplications.
      As you can see from my vertex shader i only do the usual r_ModelViewProjection * (some vertex coords).
       
      Thank you for your suggestions!
