void osg::TextureRectangle::allocateMipmap |
( |
State & |
state |
) |
const [protected, virtual] |
Allocate mipmap levels of the texture by subsequent calling of glTexImage* function.
Implements osg::Texture.
virtual void osg::TextureRectangle::apply |
( |
State & |
state |
) |
const [virtual] |
On first apply (unless already compiled), create and bind the texture, subsequent apply will simply bind to texture.

| | |
Copies pixels into a 2D texture image, as per glCopyTexImage2D. Creates an OpenGL texture object from the current OpenGL background framebuffer contents at position x, y with width width and height height. width and height must be a power of two.

| | |
Copies a two-dimensional texture subimage, as per glCopyTexSubImage2D. Updates a portion of an existing OpenGL texture object from the current OpenGL background framebuffer contents at position x, y with width width and height height. Loads framebuffer data into the texture using offsets xoffset and yoffset. width and height must be powers of two.
