I just found this thread with the extra matrix commands...
http://forum.thegamecreators.com/?m=forum_view&t=32935&b=6
Does anyone have a copy of these images that were made for it, that you can link me to-

load image "terrainsand.bmp", 1
load image "terrainheightmap.bmp", 2
load image "terraincolormap.bmp", 3
load image "terrainalphamap.bmp", 4

I am guessing I have another skybox here somewhere, but there is reference to this one also...
load object "terrainskybox.x", 2


Btw...
On the last page there is a reference to, I think they are two more functions. Can someone tell me what a "nomalize matrix function" is supposed to do?

Sorry, That's not helpfull...

I need to know if there is any specific colors needed for the heightmap, color map and alpha map...

Those media files were borrowed from VanB's holiday demo.

height maps and alpha maps are black & white images.

normalize function normalizes the terrain's normal vectors. This is used for shading. By default, all normals for each grid square are (0,1,0), that is pointing straight up. On a flat terrain object, this is fine as each square faces directly straight up. When you mold the terrain into a more realistic shape, the normals have to be update to indicate the direction the polygon is facing so that shading appears accurate.

Excellent! Awesome! Thank you!

----------------------------------------


I'm hoping I can ask a few more questions...

1: on the last page of the post jwurmz added normalize texture, did you ever finish the list of commands and should I add these two?

2: Is there some way that I can manipulate the matrix so that it waves like an ocean? (I'm talking about just big sine waves now.)

3: Can I add shaders to it, since it is now an object?

--------------

Thanks Phaelax, I really admire your skill there.

I have kind of a plan worked out if these can work together.
I think I may have even thought of a way to add boat ripples without having to change the main memblock(object matrix).

Yes all objects can have shaders put on them

set matrix normal and the auto normalize matrix functions were already part of the code, jwurmz was merely stating that because somebody couldn't see it in my code.

Quote: " Is there some way that I can manipulate the matrix so that it waves like an ocean?"

yes, but it would be slow. You'd have to update the verts in the memblock, then use "change mesh from memblock". This is actually slower than updating a matrix. With the new DBP vertex commands, it could be faster now as direct manipulation is allowed, but I have not tested this.

yes
