Morph module

After a recent request on the forums I decide to write a morphing module.

This module allows you to morph pixmaps and images in real time.


Archive contents..
1) Module - compiled into windows only at the mo. Will compile to linux when I get my mepis working.
2) example project showing you how to use the commands.
3) A morph gui. This will help you create morphs for your images.
4) docs.

Currently there isn't much error checking.
NB. If you have an image with 4*4 morph points, then it must be morphed to another image with 4*4 morph points.

If you have any question.. post them up here.
cheers

optimised drawing now with error checking.

I don't see any difference between the first and the last image.

lol

From the grabs, this appears to be "cross fading" via alpha channels rather than morphing.

It's just that he hasn't chosen enough control points or mapped them onto the two faces closely enough. Mostly morphing is just a cross-fade, combined with spacial movements and deformations of areas of the image. It looks about right but a better example would improve the appearance. Also it looks a big `jaggy`. Does it use floating point operations or integer?

yikes.. please excuse my ignorance then. If he's doing what AD said, then this could prove to be an awesome module!

the pixels move and cross fade at the same time.
The rar contains an example of a morph grid of 8*8. The above picture is 4*4. The movement is a lot better in that example.

example morph files are 03a.txt and 03b.txt for the source and destination pictures respectively.

all the operations are floating point. I'll see what I can do this weekend to make it smooother.

The rar has quickly been stuick together and I'll try to get a better release soon.

Okay, I put the pantson.mod folder in the mod directory, but am getting an error when trying to compile the example program. I get a bunch of undefined reference to brl_pixmap_ functions.

I'm sure I'm just forgetting something. It's been a long time since i've used Blitz and am trying to get back into the swing of things.

Cripes, neat :D

my fault...
I've got an optimised pixmap writepixel and readpixel in my brl.pixmap module.
I will have to update the code accordingly later at home.

Thats what happens when I rush modules out. :-(

OK new mod been uploaded.
see the link at top of the thread.

updates..
1) Removed optimised writepixel calls and replaced them with code in the module.
2) Tested on a new install of blitzmax
3) morph.bmx added to module

have fun
