Hi Delport,
Yes, I have implemented this already ... I have:
- Complex model vertex picking.
- Texture coordinates of the vertex
I need the texture coordinates of the picked vertex area, projected in the
model to paint the area, like this:

I would need two textures, an original model and a modified one, which are
applied to the model.
I assume you have the original texture (O) loaded from file.

Yeah, I understand it... but I can't work on a quad, because I need to compare
the position of the picking and the vertex in the vertex shader, and depending
on the distance between them make a new texture
Doing on a quad, the resulting image would be the next:

OK, so we've finally arrived at your problem :)

I don't know if this method helps me get what I want ...
RTT give me an image of the model from configured camera, but I need to take an
image, like model texture, painting only specific areas defined in the fragment
shader:
Code:
uniform vec2 textCoord;
uniform sampler2D baseMap;

Hi,
I'm still not sure what you want to save... Just the texture data?
You can get an osg::Image for any or all of the RTT textures. Have a
look at osgmultiplerendertargets.cpp example. Read below the line:
// we can also read back any of the targets as an image, modify this
image and push

Hi,
what comes out of the RTT camera is just a texture (or textures). What's
in the texture depends on what the camera is looking at (for no shader),
what it's looking at plus some processing on the output pixels (fragment
shader) or completely on shader code (ignore the scene and just use

Thanks for your patience!

I only found example of render to texture of the camera ...
How I had to do to have multiple render targets? like:
Code:
fragment shader
void main(void)
{
gl_FragData[0] = vec4(1.0, 0.0, 0.0, 1.0);
gl_FragData[1] = vec4(0.4, 0.4, 0.0, 1.0);
}
Thank you!

I do not get it to work I follow these steps:
Code:
// load texture as an image
imgTexture = osgDB::readImageFile(model/BAKE_OVERRIDE.jpg);
// if the image is successfully loaded
if (imgTexture)
{
imgTexture-allocateImage(3500, 3500, 1, GL_RGBA, GL_UNSIGNED_BYTE);
// create a
// load texture as an image
imgTexture = osgDB::readImageFile(model/BAKE_OVERRIDE.jpg);
// if the image is successfully loaded
if (imgTexture)
{
imgTexture-allocateImage(3500, 3500, 1, GL_RGBA,
GL_UNSIGNED_BYTE);
Why are you reallocating space for an image loaded from file ?
I asked this question in gamedev forum, and they would suggest the following:
You can not do it like you have in your example. You need to set up an FBO
with multiple render targets, and bind your editedMap as one of the targets.
But I dont have idea how can I do this... How can I configure
Hi,
I'm trying to implement a simple model painter. I detect the intersection with
the mouse and loaded model, and I applied a red color to the area:
