Horde3D

hi in terrain sample i created a 1024 x 1024 heightmap.tga and replaced to original heightmap.tga but i lost shadow and lighting when i replaced original heightmap.tga everyting is ok

what's the problem ?

Probably you haven't integrated the normal data into your hightmap. See also the "Using the Extension" section in the wiki.

thanks...

one more question
does horde3d scene editor work with command line argumants ?

You can specify a .scn File that's all. But it shouldn't be too much work to add additional things (although I currently couldn't imagine what else may be useful)

i created a pgm(from a raw data) in my program and i converted that pgm file to tga(heightmap.tga) using irfan view(in my program i run irfan view with cammand line argumants to convert pgm file to tga) so need to calculate normals in my program to give shadow and lighting in my terrain, what can i do ?

Don't convert it yourself, use the Editor's tool. It calculates the normal data and stores it together with the heightmap in the correct format. The editor's heightmap converter tool should be able to read 16bit pgms, too.

thanks i used scene editor the everyting is ok
but how can i do this programmatically ?

Just check the source code. The converter is an extra plugin.
