I have a temp fix for this but I wanna know what's going on. I load my bitmap font and it works fine. I created my own textboxes scrollbars, etc. for my game engine. Everything else works fine, except when I make my listbox. Now the listbox contains a scrollbar, a quad, and then the list of current items shown, and a quad for each of the items (for selected, current item, disabled, etc). When i add 3 items, all is well. When i add 4 items and up, my bitmap font messes up. All the letters and numbers are wrong. "Listbox: 2" becomes "Khrsanw92". It shifts every character left one. If I add an item, but don't put the text into the listbox text field (i've tried char* and string for the text field), the main bitmap font prints shifted to the right 1, and the mask bitmap font prints shifted to the left 1. I don't know how i'm manipulating the font/print command since i'm not calling anything with my listbox yet. All it does is add items, not print commands at all. My classes are being created just fine, and can be read fine. But printing text after add the items becomes messed up. Suggestions? (the temp fix btw, is to Kill the Font and Reload it.) Basically
class EntryItem
{
     public:
          EntryItem();
          string text;
          int iValue;
          float fValue;
          int entryType;
          bool disable;
          bool selected;
}
class listbox
{
     EntryItem *entries;
     int totalEntries;
     void Add_Item();
     void Add_Item(char *text);
     void Equal_EntryItem(EntryItem *b1, EntryItem *b2);
}

void Listbox::Equal_EntryItem(EntryItem *b1, EntryItem *b2)
{
     b1->text = b2->text;
     b1->iValue = b2->iValue;
     b1->fValue = b2->fValue;
     b1->entryType = b2->entryType;
     b1->disable = b2->disable;
     b1->selected = b2->selected;
}
void Listbox::Add_Item()
{
     EntryItem *temp;
     temp = 0;
     temp = new EntryItem[3];
     delete [] temp;
     int count;
     if (entries && totalEntries > 0)
     {
          temp = new EntryItem[totalEntries];
          for (count = 0; count < totalEntries; count++)
          {
               Equal_EntryItem(&temp[count], &entries[count]);
          }
          delete [] entries;          
     }
     else
     {
          entries = 0;
          totalEntries = 0;
     }
     entries = 0;
     totalEntries++;
     entries = new EntryItem[totalEntries];     
     if (temp)
     {
          for (count = 0; count < totalEntries - 1; count++)
          {
               Equal_EntryItem(&entries[count], &temp[count]);
          }
          delete [] temp;
     }
     temp = 0;
}
void Listbox::Add_Item(char *theText)
{
     int count;
     int error;     
     Add_Item();
     count = totalEntries - 1;     
     entries[count].text = theText;
}


[EDIT] I have done quite the searching for an answer, although none obtained. Some might have had one but ppl kept writing bump instead of an answer. The reason this is in Opengl and not a c++ one is that the only part messing up is the openGL part of it. [Edited by - ARelativeBelief on April 19, 2006 10:51:38 PM]

Well I'm beginning to understand a little of what's going on. My listbox class isn't the only thing to cause the problem. When i type too much text into my textbox the same thing happens. My textbox is using a std::string.
I decided to run a test, I textured a quad with my whole font. If i don't add any items to my listbox class and don't type any text, it shows up fine and all the text on the screen is fine. After typing like 8 letters all the letters are wrong. My quad with the whole font is now a different texture.
I'm confused. Am I pushing the memory around somehow? This is really puzzling me. Any help would be appreciated. I'm entering unknown memory managing with opengl.

[edit]This is my 2d component class. It holds all the texture ID's and controls

Ok, I solve my problem. No idea what I did wrong, but I changed everything over to using vectors for my arrays. Now my only issue with std::string, but i'm finding ways around the error.

      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!
