Hi,
maybe it's easier than I feel, but I don't came along with it:
I would like to map a jpeg-file onto a small part of a 3D-surface. It
works fine if I consider the entire surface. But this is not what I want
to have. The problem seems to be the array texture_coord.
If the surface is of an arry of - lets say - 1000 x 1200, how could I
map a jpeg-file onto this surface with the subsurface-grid-coordinates
[100, 50], [200,50], [200,300], [100,300]? And: I hope that the
jpeg-file can have a higher resolution than [100 x 250] pixels for this
example?
Whatever I try - I get the error-message "number of vertices, normals,
and texture coordinates do not match". Concerning to the online-help
"TEXTURE_COORD property defines how individual data points within the
image data are mapped...". I don't hope that each pixel in the jpeg-file
must be referenced by corresponding coordinates....
Thanks for each encouraging hint...
Harald
