The SoGLTextureImageElement is used to control the current GL texture.
This is a lazy element. It is evaluated in SoShape::shouldGLRender().
|
protectedvirtual |
The destructor.
|
static |
This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.
|
static |
This static method initializes static data in the SoGLTextureImageElement class.
|
virtual |
FIXME: write doc.
Reimplemented from SoTextureImageElement.
|
virtual |
This method is called every time a new element is required in one of the stacks. This happens when a writable element is requested, using SoState::getElement() or indirectly SoElement::getElement(), and the depth of the current element is less than the state depth.
Override this method if your element needs to copy data from the previous top of stack. The push() method is called on the new element, and the previous element can be found using SoElement::getNextInStack().
Reimplemented from SoElement.
This method is callled when the state is popped, and the depth of the element is bigger than the current state depth. pop() is called on the new top of stack, and a pointer to the previous top of stack is passed in prevTopElement.
Override this method if you need to copy some state information from the previous top of stack.
Reimplemented from SoElement.

static |
Sets the current texture. Id didapply is TRUE, it is assumed that the texture image already is the current GL texture. Do not use this feature unless you know what you're doing.
|
static |
The size returned by this function will just be a very coarse estimate as it only uses the more or less obsoleted technique of calling glGetIntegerv(GL_MAX_TEXTURE_SIZE).
For a better estimate, use SoGLTextureImageElement::isTextureSizeLegal().
Note that this function needs an OpenGL context to be made current for it to work. Without that, you will most likely get a faulty return value or even a crash.
|
virtual |
Returns true if the texture with the given dimensions is supported by the current OpenGL context.
If zsize==0, 2D texturing is assumed, else 3D texturing is assumed.
This function uses OpenGL proxy textures and will fall back to what you get from SoGLTextureImageElement::getMaxGLTextureSize() if proxy textures are not supported (i.e. OpenGL version < 1.1 and GL_EXT_texture not available). In the 3D case, 3D textures need to be supported (OpenGL >= 1.2 or GL_EXT_texture3D).
Note that this function needs an OpenGL context to be made current for it to work. Without that, you will most likely get a faulty return value or even a crash.
This function is an extension for Coin, and it is not available in the original SGI Open Inventor v2.1 API.
|
static |
Return TRUE if at least one pixel in the current texture image is transparent.
|
protectedvirtual |
Called by containsTransparency(). Returns TRUE if image data has transparency. Default method does a very poor job of detecting this, since it returns TRUE when the number of components are 2 or
