[solved] Unable to deform landscape

Hello,

First of all, congratulation for PLSM2, which is very useful for me.

And sorry for my horrible english...

I am working on tools which would able to deform a Landscape.

Unfornately, I don't achieve to change any height.

I found two ways :

One with DeformationCenter which may work relatively to current height.
An other with setHeightCenter which may work with asolute coordinates.

I use BrushScale, BrushArrayWidth, BrushArrayHeight and BrushArray options to set up the brush.

I also use fillBrushArray when I try to use setHeightCenter.

Here are two of my tests (They would raise a part of the land of 100) :

Ogre::Vector3 Center;
if (Cursor::getInstance()->getCenter(Center))
{
Ogre::uint i;

// Select scale
Ogre::Real brushScale(Cursor::getInstance()->getSize() / 512);
mSceneMgr->setOption("BrushScale", &brushScale);

// Select size
i = 512;
mSceneMgr->setOption("BrushArrayWidth", &i);
mSceneMgr->setOption("BrushArrayHeight", &i);

// Put the array
Ogre::Real * deltaArray = new Ogre::Real[512 * 512];
mSceneMgr->setOption("BrushArray", deltaArray);

// Put value in the array
for (i = 0 ; i < 512 * 512 ; i++)
deltaArray[i] = 100;

// Deform
mSceneMgr->setOption("DeformationCenter", &Center);
}


Ogre::Vector3 Center;
if (Cursor::getInstance()->getCenter(Center))
{
Ogre::uint i;

// Select scale
Ogre::Real brushScale(Cursor::getInstance()->getSize() / 512);
mSceneMgr->setOption("BrushScale", &brushScale);

// Select size
i = 512;
mSceneMgr->setOption("BrushArrayWidth", &i);
mSceneMgr->setOption("BrushArrayHeight", &i);

// Put the array
Ogre::Real * deltaArray = new Ogre::Real[512 * 512];
mSceneMgr->setOption("BrushArray", deltaArray);

// Get current values
mSceneMgr->setOption("fillBrushArray", &Center);

// Update values
for (i = 0 ; i < 512 * 512 ; i++)
deltaArray[i] = deltaArray[i] + 100;

// Affect values
mSceneMgr->setOption("setHeightCenter", &Center);
}

Cursor::getInstance()->getSize() return a number between 10 and 510.
Diveded by 512, it's between 0 and 1.
Cursor::getInstance()->getCenter(Center) put in Center a valid point on the land.

The first code do nothing.
The second one failed on an assertion of mNumTexture > 0.

And finally, the cfg file we are using, which could help you to help me :

# where to put camera on load.
BaseCameraViewpoint.x=0.0f
BaseCameraViewpoint.y=60.0f
BaseCameraViewpoint.z=0.0f

Baselookat.x=0.0f
Baselookat.y=60.0f
Baselookat.z=0.0f

Does anybody can help me please ?

ImagePaging isn't a deformable texture so textureModifiable should be no.

Thanks a lot.

May we will have to update pages after deform it, but it seems ok.
