Member Function Documentation

void SoGLMultiTextureImageElement::initClass ( void  ) [static]

This static method initializes static data in the SoGLMultiTextureImageElement class.

Reimplemented from SoMultiTextureImageElement.

void SoGLMultiTextureImageElement::set ( SoState *const  state,
SoNode *const  node,
const int  unit,
SoGLImage image,
const SoTextureImageElement::Model  model,
const SbColor blendColor 
) [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.

SbBool SoGLMultiTextureImageElement::hasTransparency ( SoState state) [static]

Returns TRUE if any of the images have at least one transparent pixel.

Since:
Coin 3.1
SbBool SoGLMultiTextureImageElement::hasTransparency ( const int  unit) const [protected, virtual]

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 4. Override whenever it is important to know this (SoGLTextureImageElement overrides it to avoid transparency handling where possible).

Reimplemented from SoMultiTextureImageElement.
