Member Function Documentation

◆ allocateMipmap()

virtual void osg::Texture::allocateMipmap ( State state) const
protectedpure virtual

Allocate mipmap levels of the texture by subsequent calling of glTexImage* function.

Implemented in osg::Texture2D, osg::Texture3D, osg::TextureRectangle, osg::Texture1D, osg::Texture2DArray, osg::TextureCubeMap, osg::TextureBuffer, and osg::Texture2DMultisample.

◆ allocateMipmapLevels()

void osg::Texture::allocateMipmapLevels ( )

Force a manual allocation of the mipmap levels on the next apply() call.

User is responsible for filling the mipmap levels with valid data. The OpenGL's glGenerateMipmapEXT function is used to generate the mipmap levels. If glGenerateMipmapEXT is not supported or texture's internal format is not supported by the glGenerateMipmapEXT, then empty mipmap levels will be allocated manually. The mipmap levels are also allocated if a non-mipmapped min filter is used.

Texture is a pure virtual base class, apply must be overridden.

Reimplemented from osg::StateAttribute.

Implemented in osg::Texture2D, osg::Texture3D, osg::TextureRectangle, osg::Texture1D, osg::Texture2DArray, osg::TextureCubeMap, osg::TextureBuffer, and osg::Texture2DMultisample.
