Irrlicht Engine

Hi,

I need to access CImage in my external meshloader to build a texture of it. However, CImage is not in the Irrlicht include directory, but only in the internal sources. I can still compile it including the inner sources, and it does link on Linux. However, that should not be the way it is done? Moreover, I get linker errors on Windows.

Can someone please help me? I need either a way to access C Image on Windows or (I'd prefer that) an alternative to using CImage (without inheriting IImage myself).

Thanks,
Lo

Yes, you should create the image via the driver methods (createImage...) and use the interface provided by IImage.

Yeah, I know what you mean, but I have the data as an array of pixels. Now, As you say it, I will have to write those into a file (where I'll need to give them a header and all that information), to then load them from this file again into an IImage*? This would cause a large loss in runtime: imagine creating one file for each of those 1500 lightmaps...

Anyways, if this is the case, which file format is the easiest to store an array of 16bit-pixels? TGA? BMP?

Check out IVideoDriver::createImageFromData. It does just what you want to do: creates an IImage from an array of pixels.

Yup, if the data is already in a proper data format, just create the image from the raw data. Otherwise create an empty image (also with some createImage... call) and fill the data in while converting it.

Good idea Thank you so much!
