OpenGL
OpenGL application standalone installer

6 posts in this topic

I have made an OpenGL based game program for windows platform using Visual C++(Express edition 2008). i'm using GLUT. Now that the project is complete, the next step is to create a standalone installer for any windows based system.
Can anyone give me an insight into the details i should know while creating installer packages?

>> Is it possible to generate the setup file using Visual Studio itself?

>>How do i include the visual studio redistributable package in the setup?

>>While testing the project on a Windows 7 system, the program continuously crashed saying "APPCRASH/ faulting module openGL32.dll".
I tried replacing the opengl32.dll file with previous versions but didn't work. Tried teinstalling the OpenGL, even reinstalled the drivers (Intel 82945G Express chipset) ,but the bug persists.

Using glut you have to include that...anyway the best solution is to develop cross platform. Why? Because you can more easily crosscheck for faults and get a broader view while testing with different compilers.

Double check that you are sticking to the OpenGL standard. Just because something 'works' (or appears to work) on some driver does not mean you are not doing several big no-nos forbidden by the standard that might break your program on another card or even after the next driver update.

Of course it could also be the driver, I have had bad experience with Intel drivers. If it is the driver, there is no real solution. Possible alternatives are:
1) find out what functionality causes the problem and do not use it. In my case the driver claimed it could do FBOs but just failed horribly at it.
2) use a different code path for cards known to cause problems.
3) accept that the program won't run on that line of cards.
4) hope for driver updates. Of course in my case Intel hadn't updated the Vista driver since 2009, but you probably have more luck on Windows 7.

The application performed just fine under Windows XP on the same system. So i doubt if its the driver support issue which is causing the bug.. Edited by itsme25

Windows XP and Windows 7 have very different drivers so don't rule that out.

I don't know if you have tried it already but I found a program called gDEBugger quite useful for finding opengl messups that I had made:

[url="http://www.gremedy.com/"]http://www.gremedy.com/[/url]

It hopefully might flag up an error either running on your development system, or you could run it unders windows 7 on the test system.

Could be something like writing to memory outside where you should be, or you are not initializing something you are passing to opengl and relying on whatever happens to be in the memory to stop it crashing. I'd triple check everything you are sending to opengl. I had a similar bug where I was not resetting glPixelStorei with glTexSubImage2D recently.

If you aren't able to install the IDE etc on the win 7 environment, you could also make several builds of your program, and #ifdef out your opengl code, then gradually reintroduce it bit by bit to try and pin down what is causing the issue.

If you want to create an Setup, i recommend you to use an Windows Installer compliant Setup Authoring Tool.
Be Warned: There are some NON MSI (Windows installer Package) Tools out there but they are not supported from
Microsoft and bypassing the Windows Installer System. I using WIX Windows Installer XML (OpenSource and free
from Microsoft) for creating Windows Installer compliant MSI Setups wich runs flawless on XP/Vista/Win7/8 (32/64-Bit)
http://wix.codeplex.com/releases/view/60102

But this is NOT an easy click by click Setup Creator. You have to study and learn to use it ( i think you need upto 1-3
a days to figure it out for your needs.But if you know to do it, you never miss it anymore. Of cause you can also generate
FullPatches and Deltapatches *(.msp) Deltapatches are great if you change a hughfile and only to shiip the changed
bits but not the complete, largefile. Of cause Repair/Remove/Add User, Add Service/Unisntall Service Registry and
File Copy and Shortcut Creation can be performed.

      Hello, I have been working on SH Irradiance map rendering, and I have been using a GLSL pixel shader to render SH irradiance to 2D irradiance maps for my static objects. I already have it working with 9 3D textures so far for the first 9 SH functions.
      In my GLSL shader, I have to send in 9 SH Coefficient 3D Texures that use RGBA8 as a pixel format. RGB being used for the coefficients for red, green, and blue, and the A for checking if the voxel is in use (for the 3D texture solidification shader to prevent bleeding).
      My problem is, I want to knock this number of textures down to something like 4 or 5. Getting even lower would be a godsend. This is because I eventually plan on adding more SH Coefficient 3D Textures for other parts of the game map (such as inside rooms, as opposed to the outside), to circumvent irradiance probe bleeding between rooms separated by walls. I don't want to reach the 32 texture limit too soon. Also, I figure that it would be a LOT faster.
      Is there a way I could, say, store 2 sets of SH Coefficients for 2 SH functions inside a texture with RGBA16 pixels? If so, how would I extract them from inside GLSL? Let me know if you have any suggestions ^^.

      EDIT: I thought this was restricted to Attribute-Created GL contexts, but it isn't, so I rewrote the post.
      Hey guys, whenever I call SwapBuffers(hDC), I get a crash, and I get a "Too many posts were made to a semaphore." from Windows as I call SwapBuffers. What could be the cause of this?
      Update: No crash occurs if I don't draw, just clear and swap.

      Hey devs!
       
      I've been working on a OpenGL ES 2.0 android engine and I have begun implementing some simple (point) lighting. I had something fairly simple working, so I tried to get fancy and added color-tinting light. And it works great... with only one or two lights. Any more than that, the application drops about 15 frames per light added (my ideal is at least 4 or 5). I know implementing lighting is expensive, I just didn't think it was that expensive. I'm fairly new to the world of OpenGL and GLSL, so there is a good chance I've written some crappy shader code. If anyone had any feedback or tips on how I can optimize this code, please let me know.

Or am I just being unrealistic about what I can do? Thanks in advance

      Hi,
      Not sure to post at the right place, if not, please forgive me...
      For a game project I am working on, I would like to implement a 2D starfield as a background.
      I do not want to deal with static tiles, since I plan to slowly animate the starfield. So, I am trying to figure out how to generate a random starfield for the entire map.
      I feel that using a uniform distribution for the stars will not do the trick. Instead I would like something similar to the screenshot below, taken from the game Star Wars: Empire At War (all credits to Lucasfilm, Disney, and so on...).

      Is there someone who could have an idea of a distribution which could result in such a starfield?
      Any insight would be appreciated

      I have just noticed that, in quake 3 and half - life, dynamic models are effected from light map. For example in dark areas, gun that player holds seems darker. How did they achieve this effect ? I can use image based lighting techniques however (Like placing an environment probe and using it for reflections and ambient lighting), this tech wasn't used in games back then, so there must be a simpler method to do this.
      Here is a link that shows how modern engines does it. Indirect Lighting Cache It would be nice if you know a paper that explains this technique. Can I apply this to quake 3' s light map generator and bsp format ?
