Hello friends!
I began a study to learn how to modify the mesh of my terrain in real time!
This is my first contact with this subject, so I decided to start with the basics then go for getting more advanced!

I would then share with the community the results that I am getting over the learning!

And also wish I could use this topic to take my doubts about it

hi

check this out: Widi's terrain deformer for A7 and A8
I got ideas for my terrain deformer mainly from this.

the download link is broken but you should find it in an AUM based on the date of this thread.

moreover you don't need updatehull since last version update, that bug was fixed finally.

Tanks Sivan (^.^).
I'm not finding the sources of Widi!
And thanks for letting me know about the c_updatehull. I will update my files!

If you have files of the WIDI, make available to me! I would be grateful

okay, I can upload it.

Updated the first post of this topic!

As you can see, this new version was implemented options for multiple Vertex and also to Smooth move Multiple vertex!

Questions for next version!
==================================================
that way I can modify the scale of the texture in places where the terrain mesh was modified?


And Other Doubs.
How can I PAINT my texture in real time?

You mean the stretching? This is caused by the UV map and can not sufficiently be recalculated without distorting neighbouring terrain patches. But you could use a ttriplanar UV mapping with a shader to calculate texcoords by slope, see this: http://memoirsofatexel.blogspot.de/2010/08/terrain-triplanar-uv-mapping.html or http://devblog.drheinous.com/2012/06/triplanar-texturing.html or http://http.developer.nvidia.com/GPUGems3/gpugems3_ch01.html.

If you are working with a blendmap, you need to update a texture. For this you can use bmap_process to apply changes, or you change the bitmap with the pixel functions, which is kinda slow. Basically, all you have to do per frame is

1.) to convert the mouse cursor position from view space to object space
2.) convert that from object to uv space as offset for the drawing
3.) iterate over all pixels: for each pixel calculate strength and update

in your multitexturing shader you have to use this bitmap then; you can either update the entity's texture of the blendmap or you create a dynamic blendmap on the fly and assign it as material bmap on skin 1 or else.

Again I thank you for taking the time and patience to help me HeelX! (^.^)!.
The links on UV textures that you presented to me are very useful, I will take some time studying to implement on my project!

I will first try to implement the painting of the terrain in real time!
I want to use Blend Map for texture.



This seems way cooler (ô.Ô)LOL!.
I believe that the process more effective would be I actually use a dynamic texture!.
When I'm Painting the terrain, I'm actually painting the blend Map and refreshing the terrain shader...
+ ou - (^.^)

I will begin implementing the first 3 steps you showed me.


I will consult the Manual about bmap_process!

If you have something else to help me, every hint and supporting material are welcome!.

Soon I'll be showing my results!

==========================================================

Now I can already paint the land and save BlendMAP after modifications.

I believe that now it is interesting to use the shader to multiple terrain textures from a painted Blendmap

Before starting to implement this part I would like someone to help me with the problem mentioned below!
Doubt:
-----------------
I Am Using bmap_save(BMAP*, STRING* name), to save the modified map. But he's saving the texture mirrored!

How can I save the map without a mirror?

TANKX BROTHERS!

Don't use tga, but save as BMP or PNG instead.

not working when using BMP!. After he saves I can not run again.
BAD FILE FORMAT!. The map is being saved with some property that disables executable rights later!

Apparently, he is converting bmp 24bit to 32bit
