OpenGL Vista and OpenGL

Recommended Posts

Volatility    122
Okay I appreciate anyone that has actually got so far as to read this, with the amount of miss information and people dumping on microsoft about the supposed lack of support im sure everyone has better things to do than read a thread that heads up OpenGl and vista in the same sentence. Needless to say I think ive done something very stupid lol, I read up everything i could possibly find about support for OpenGL on Windows Vista and being the incredible optimist that I am decided to impliment my project with OpenGL. Ill admit to not being the most knowledgeable computer programmer in the world but my problem seems to stem from wglGetPixelFormatAttribivARB. Ironically I can get things up and going using the normal PIXELFORMATDESCRIPTOR technique but (correct me if im wrong) theres no way to get multisampling working though the old method? In particular I can get a pixel format that supports WGL_SUPPORT_OPENGL_ARB but was getting nothing on swapbuffers, haha never thought id be happy with a simple black screen :P. Does anyone know the relationship between the formats returned by wglGetPixelFormatAttribivARB and the windows PIXELFORMATDESCRIPTORS? Ive tried querying a format that supposedly supports WGL_SUPPORT_OPENGL_ARB using DescribePixelFormat to find that PFD_SUPPORT_OPENGL isnt flagged which obviously seams to leaves me up shit creek. Any help about whats going on would be appreciated. ( Yes ive tried turning dwmEnableComposition to DWM_EC_DISABLECOMPOSITION which doesnt seem to do me much good in this case either. )

That's correct.

Try the demoes from developer.nvidia.com
The SDK there has soe demoes that show multisampling.

Also, nehe has a tutorial on this.

You get the pixelformat using a temporary window (hidden) and then use it to setup multisample on your main window and that's all. Using SetPixelFormat of course.

      Hello, My name is Matt. I am a programmer. I mostly use Java, but can use C++ and various other languages. I'm looking for someone to partner up with for random projects, preferably using OpenGL, though I'd be open to just about anything. If you're interested you can contact me on Skype or on here, thank you!

      Hello, my name is Mark. I'm hobby programmer. 
      So recently,I thought that it's good idea to find people to create a full 3D engine. I'm looking for people experienced in scripting 3D shaders and implementing physics into engine(game)(we are going to use the React physics engine). 
      And,ye,no money =D I'm just looking for hobbyists that will be proud of their work. If engine(or game) will have financial succes,well,then maybe =D
      Sorry for late replies.
      I mostly give more information when people PM me,but this post is REALLY short,even for me =D
      So here's few more points:
      Engine will use openGL and SDL for graphics. It will use React3D physics library for physics simulation. Engine(most probably,atleast for the first part) won't have graphical fron-end,it will be a framework . I think final engine should be enough to set up an FPS in a couple of minutes. A bit about my self:
      I've been programming for 7 years total. I learned very slowly it as "secondary interesting thing" for like 3 years, but then began to script more seriously.  My primary language is C++,which we are going to use for the engine. Yes,I did 3D graphics with physics simulation before. No, my portfolio isn't very impressive. I'm working on that No,I wasn't employed officially. If anybody need to know more PM me.

      I am developing my engine using the OpenGL 3.3 compatibility profile. It runs as expected on my NVIDIA card and on my Intel Card however when I tried it on an AMD setup it ran 3 times worse than on the other setups. Could this be a AMD driver thing or is this probably a problem with my OGL code? Could a different code standard create such bad performance?

      I'm trying to get some legacy OpenGL code to run with a shader pipeline,
      The legacy code uses glVertexPointer(), glColorPointer(), glNormalPointer() and glTexCoordPointer() to supply the vertex information.
      I know that it should be using setVertexAttribPointer() etc to clearly define the layout but that is not an option right now since the legacy code can't be modified to that extent.
      I've got a version 330 vertex shader to somewhat work:
      #version 330 uniform mat4 osg_ModelViewProjectionMatrix; uniform mat4 osg_ModelViewMatrix; layout(location = 0) in vec4 Vertex; layout(location = 2) in vec4 Normal; // Velocity layout(location = 3) in vec3 TexCoord; // TODO: is this the right layout location? out VertexData { vec4 color; vec3 velocity; float size; } VertexOut; void main(void) { vec4 p0 = Vertex; vec4 p1 = Vertex + vec4(Normal.x, Normal.y, Normal.z, 0.0f); vec3 velocity = (osg_ModelViewProjectionMatrix * p1 - osg_ModelViewProjectionMatrix * p0).xyz; VertexOut.velocity = velocity; VertexOut.size = TexCoord.y; gl_Position = osg_ModelViewMatrix * Vertex; } What works is the Vertex and Normal information that the legacy C++ OpenGL code seem to provide in layout location 0 and 2. This is fine.
      What I'm not getting to work is the TexCoord information that is supplied by a glTexCoordPointer() call in C++.
      Question:
      What layout location is the old standard pipeline using for glTexCoordPointer()? Or is this undefined?
       
      Side note: I'm trying to get an OpenSceneGraph 3.4.0 particle system to use custom vertex, geometry and fragment shaders for rendering the particles.

      Hi i am new to this forum  i wanted to ask for help from all of you i want to generate real time terrain using a 32 bit heightmap i am good at c++ and have started learning Opengl as i am very interested in making landscapes in opengl i have looked around the internet for help about this topic but i am not getting the hang of the concepts and what they are doing can some here suggests me some good resources for making terrain engine please for example like tutorials,books etc so that i can understand the whole concept of terrain generation.
