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:
[Image: http://img818.imageshack.us/img818/9672/painting.jpg ] You can see the selected point on the texture image. I edit the texture image with Qt. But I want to save all changes to a new texture. It can be done in the fragment shader? I can think ... Code: uniform vec2 textCoord; uniform sampler2D baseMap; uniform sampler2D editedMap; uniform vec3 interPos; varying vec4 color; varying vec2 Texcoord; varying vec3 position; void main( void ) { float radio = 8.0; vec3 a = position - interPos; float dist = sqrt((a.x*a.x)+(a.y*a.y)+(a.z*a.z)); vec4 paintColor = vec4(1.0,0.0,0.0,1.0); if(dist<radio){ gl_FragColor = texture2D( baseMap, Texcoord ) * color + paintColor; //editedMap = texture2D( baseMap, Texcoord ) * color + paintColor; } else{ gl_FragColor = texture2D( baseMap, Texcoord ) * color; //editedMap = texture2D( baseMap, Texcoord ) * color; } } Thank you!
