OpenGL University project - investigating features of OpenGL 1.4

Recommended Posts

Billy Lee    122
I''m starting my final year in my Masters in Software Engineering and I''m looking to do a project involving the creation of a game. I can''t just say "I want to create a game" so I''ve decided to investigate and implement the new features of OpenGL 1.4 into a simple game like Asteriods to create lots of special effects. The project has to be something relatively new that others haven''t done before, or at least compare favourably to something similar (in this case, another particular 3D Asteroids game). Do you think this will make a good project? Any comments and suggestions appreciated.

There''s not a whole lot more interesting about OpenGL 1.4 than there is over 1.3. Depth textures and shadows are new, but I don''t think that''s too exciting.

If you''re going to do a "research project" using OpenGL and want to do something new and cool I would suggest looking at the ARB_vertex_program and ARB_fragment_program extensions not just OpenGL 1.4. These are *very* new pieces of OpenGL that have recently been standardized. These extensions haven''t been used much yet so many developers are interested in how to make cool effects with them. If you can implement some of those effects, you could definately wow some people.

Thanks. I think I will do that. I''ve also been looking up on NVidia''s Cg technology. As I understand it, it sits on top of OpenGL and is a way of producing good special effects easily using the C language. Does anyone know much about this? Would this be a good thing to investigate for my project as an alternative? Or maybe utilise the ARB_vertex_program and ARB_fragment_program extensions using Cg.:D

Nooooooo...of course I'm biased since I work for ATI.

Seriously though, the only company thinking of implementing Cg is NVidia. I wouldn't base my university project on 1 company's technology. There is (or will be) implementations of ARB_fragment_program and ARB_vertex_program on multiple cards from many different companies. Certainly, Cg isn't even usable at this point considering NVidia hasn't produced hardware that can actually run Cg Shaders efficiently.

If you can wait a few months, consider doing a project using GL2 shading extensions. There will, hopefully, be a few companies with 1st round implementations.

dun think its a good idea to based ur project esp. a MASTER thesis on something like OGL1.4 or just implementing effects with ARB extensions. Every graphics programmer and his dog/cat/hamster/grandma are doing it.

I think u need to go back and research on which direction is better. Seems like u dun have much idea about high level shader languages or even low level shader stuff. Other than shaders, the other stuff in OGL are quite rudimentary, unless if u r dwelling into some obscure mathematical theory of triangle rasterization or graphics algorithm. Me think best is for u to do something that is your forte instead of trying to explore new world.

i thought arb_vetex_program IS part of opengl1.4 (it saiz in my opengl1.4spec), im not to sure about fragemnet progrogram im pretty sure it aint though

No, it's not technically part of 1.4 because M$ has some obscure IP claim on it and the ARB bylaws state that if anybody claims IP on an extension it can't be part of standard OpenGL.

Not that it really matters whether it's part of 1.4 or not since M$ will probably never ship an implemenation above 1.1. Either way, on windows at least, you'd have to access the functionality as an extension.

flipstar, the project has to involve something new. I have studied like crazy learning OpenGL through the summer holidays so I really want to do something with that. It''s true that I don''t know much about shaders. I should read up on them. I really want to make a game though for my project. The end result has to be a piece of software.

If ur doing a software engineering masters couldnt u do something along the lines of "design patterns of real-time 3d game effects". I''m sure there are a lot of uncharted patters that could be useful.
You could always then create a asteriods game using OGL to demonstrate the efficent implementation of your patterns and how they are useful in keeping the game modular, maintainible, understandable...(insert software engineering terms here)...etc

That''s true...this would be more "Software Engineering" like. Using shaders and doing some cool math tricks is more "Computer Science" like.

      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!
