I'd like to test my generated height maps in AppGameKit but I'm not sure what's wrong.

I'm trying to generate an object from height map but I've been unable to pinpoint the problem.

I've been generating RGB height map with my command line tool, which generates PNG images and power of two in size. The CreateObjectFromHeightMap isn't working, it prints "Image couldn't been found" on the console but the command still generates some sort of height data on the plane, it just doesn't match the image provided. And if I'm trying to texture it with some image in correct size, the plane seems to be drawn with a sort chessboard graphics on it with red color in the center of the plane.

I'm not on the PC right now so I can't provide screenshots, code or the height map images, but I can do it later today or tomorrow.

Thanks for helping!

Well this would be the problem.

The heightmap you're getting is probably a heightmap taken from the default image that AppGameKit uses when it fails to load an image, which like you say is a kind of checkerboard thing with a big cross through the middle.

Are you sure the CreateObjectFromHeightMap call is getting the correct path to the heightmap file?

Well, in the C++project I had copied the same heightmap image into root, media and executable directories, and none of these worked. I haven't tried this on Windows, yet.

If you are in Linux pay attention to capitals and lower letters in the filename

Best regards

Hi BraindeaD,

I have file names hard-coded currently, do that shouldn't be the issue. Thanks for the tip, though.

In linux filename's are case sensitive so if you try to open "Map.png" and the file on disk is "map.png" then it will fail

I think I got it sorted. Apparently I had to call
command and set it to media folder manually.
