OpenGL "Intermediate" Direct3D Tutorials?

Recommended Posts

skyfire360    228
Hey again! While I have programmed graphics before using OpenGL, I'm a complete beginner when it comes to Direct3D. After finding myself some basecode from Andypike and Drunkenhyena, I pretty much blundered my way though the code and ended up adding 32 bit color support (is it normal to have a garphics card support only XRGB and not ARGB?), 32 bit z-buffer, and lost device trapping. Because I have a bad habit of looking forward and getting ahead of myself, after drawing my first triangle I looked on down towards the texturing and multitexturing code examples. To my suprise, I found only tutorials on static texturing: no texture matrix code, no multitexture/multipass code, and no bump-mapping code. After wandering around the internet for a while, I found that most of the online tutorial sites around (with the notable exception of UltimateGameProgramming) mainly deal with the low-level, "This is a polygon", "This is a light" kind of tutorials. The few that do deviate from this format usually - like the MSDN examples - go straight into Vertex Shaders and Pixel Shaders. My point is that I'm feeling like I'm missing something in the middle, somewhere between texturing and Pixel Shaders. Of course, it's possible that could be because I'm somewhat intimidated by the power and complexity of Shader code and fail to understand them correctly. Can anyone point me to some mid-level tutorials, or if not, to a good Direct3D (preferably DirectX9) book that would make the Direct3D Pipeline make more sense to me?

IMHO,what you want to do is spend a lot of time in the SDK docs.

I also started with OGL,and i was looking for similar type of tutorials,but did not find many.

There are a few specialized books such as the ShaderX series(though not really what you would want to jump straight into),though IMO,most directX books don't have a very long life value(if you understand my meaning -:)

btw... its about time some of the DirectX gurus here wrote a decent up-to-date normal mapping tutorial using DirectX9 with hardware(or software) skinned characters....hahah

right now,it would make me happy to find this kind of DX tutorial on google-:)

The best thing i can give you if your coming from OGL,is
www.codesampler.com

which has very good examples in both Opengl,DirectX8 and 9,
and if you study the examples,it might make the learning curve
a bit easier.

Hope this helps.

Thanks for the replies everyone!

Axiverse: Yes and no. I downloaded and installed the DX9 Summer Update 2004 SDK, but upon opening and looking around inside the distribution all I found were articles on Vertex Shaders - I couldn't find any of the old DX8 "this is a polygon" kind of examples/projects. Are they just hidden somewhere in there where I can't find 'em?

AP: Thanks for the support! I'll check out codesampler tonight

      I assumed that if a shader is computationally expensive then the execution is just slower. But running the following GLSL FS instead just crashes
      void main() { float x = 0; float y = 0; int sum = 0; for (float x = 0; x < 10; x += 0.00005) { for (float y = 0; y < 10; y += 0.00005) { sum++; } } fragColor = vec4(1, 1, 1 , 1.0); } with unhandled exception in nvoglv32.dll. Are there any hard limits on the number of steps/time that a shader can take before it is shut down? I was thinking about implementing some time intensive computation in shaders where it would take on the order of seconds to compute a frame, is that possible? Thanks.

      There are studios selling applications which is just copying any 3Dgraphic content and regenerating into another new window. especially for CAVE Virtual reality experience. so that the user opens REvite or CAD or any other 3D applications and opens a model. then when the user selects the rendered window the VR application copies the 3D model information from the OpenGL window. 
      I got the clue that the VR application replaces the windows opengl32.dll file. how this is possible ... how can we copy the 3d content from the current OpenGL window.
      anyone, please help me .. how to go further... to create an application like VR CAVE. 
       
      Thanks

      hi all,

      i am trying to build an OpenGL 2D GUI system, (yeah yeah, i know i should not be re inventing the wheel, but this is for educational and some other purpose only),
      i have built GUI system before using 2D systems such as that of HTML/JS canvas, but in 2D system, i can directly match a mouse coordinates to the actual graphic coordinates with additional computation for screen size/ratio/scale ofcourse.
      now i want to port it to OpenGL, i know that to render a 2D object in OpenGL we specify coordiantes in Clip space or use the orthographic projection, now heres what i need help about.
      1. what is the right way of rendering the GUI? is it thru drawing in clip space or switching to ortho projection?
      2. from screen coordinates (top left is 0,0 nd bottom right is width height), how can i map the mouse coordinates to OpenGL 2D so that mouse events such as button click works? In consideration ofcourse to the current screen/size dimension.
      3. when let say if the screen size/dimension is different, how to handle this? in my previous javascript 2D engine using canvas, i just have my working coordinates and then just perform the bitblk or copying my working canvas to screen canvas and scale the mouse coordinates from there, in OpenGL how to work on a multiple screen sizes (more like an OpenGL ES question).
      lastly, if you guys know any books, resources, links or tutorials that handle or discuss this, i found one with marekknows opengl game engine website but its not free,
      Just let me know. Did not have any luck finding resource in google for writing our own OpenGL GUI framework.
      IF there are no any available online, just let me know, what things do i need to look into for OpenGL and i will study them one by one to make it work.
      thank you, and looking forward to positive replies.

      I have a few beginner questions about tesselation that I really have no clue.
      The opengl wiki doesn't seem to talk anything about the details.
       
      What is the relationship between TCS layout out and TES layout in?
      How does the tesselator know how control points are organized?
          e.g. If TES input requests triangles, but TCS can output N vertices.
             What happens in this case?
      In this article,
      http://www.informit.com/articles/article.aspx?p=2120983
      the isoline example TCS out=4, but TES in=isoline.
      And gl_TessCoord is only a single one.
      So which ones are the control points?
      How are tesselator building primitives?

      I've been developing a 2D Engine using SFML + ImGui.
      Here you can see an image
      The editor is rendered using ImGui and the scene window is a sf::RenderTexture where I draw the GameObjects and then is converted to ImGui::Image to render it in the editor.
      Now I need to create a 3D Engine during this year in my Bachelor Degree but using SDL2 + ImGui and I want to recreate what I did with the 2D Engine. 
      I've managed to render the editor like I did in the 2D Engine using this example that comes with ImGui. 
      3D Editor preview
      But I don't know how to create an equivalent of sf::RenderTexture in SDL2, so I can draw the 3D scene there and convert it to ImGui::Image to show it in the editor.
      If you can provide code will be better. And if you want me to provide any specific code tell me.
      Thanks!
