The problems after a successful install:
The sentence, which is present in the introduction, is related to the problems, which emerge after a successful installation. Note that after a successful installation only this means that the process of installation is very important to be finished properly.
So if you face any problem then you have to first check whether you have installed World Wind properly or not. If you have installed World Wind application properly then you can go for further checks. Let us now discuss the problems one by one.
Problems after a successful installation: The problems, which commonly emerge even after the successful installation of World Wind, are as follows:
World Wind Fatal Error dialog box: This error if emerges commonly when you try to make the settings of your display in either in sixteen or thirty two bit color. The twenty-four or thirty-two bit color is also giving trouble to the users in some cases. Mostly the sixteen bit also works without any problems. To minimize the problems of this type you can always check the graphic card compatibility.
The flashing of the “direct 3Dm_Device 3d” error: This error is regarding the video compatibility of the personal computer with the version of NASA World Wind. This determines whether World Wind will work with your computer graphics card. To counteract this check the drivers that are latest and then download the latest ones. This is very important before taking any further step towards solving this problem.
First check your video card if work is not done then you can update the drivers which are available in the market. Load nVidia drivers if possible to you. This problem gets worst when you are viewing the three dimensional views when you are at a lower viewing angle. This is also applicable when you are backing away means that you are at a higher altitude from the earth’s surface.
It will show problem when you are more directly straight down. This problem as big it might be but it can be fixed easily. For example if you rotate the view by right-button drag horizontal can cause the altered form to go. Note that some times in this case you can face problem where even a movement of mouse will start the corruption. This can happen even when all the other things which are involved in it are right like altitude, tilt, rotation etc.
One of the remedy for this type of problem is that you can always turn off all the layers which minimizes the problem. Other ways to solve this problem are given above so always remember that if you do screwing of the “AGP” aperture which is present in the bios is doesn’t help.
Since the increase of the aperture will cause the system to utilize the texture memory but in the case where the card runs out of onboard memory. So it will be good if you just leave it forever at 256M.
So the summary of the video problem is that you ensure that your video card drivers are up to date and Managed DirectX is installed. Also, try the loading of Direct X Diagnosis program by going to the start menu, then run, and then type ‘dxdiag’. Below the display option make sure that the lot is operational and enabled.
