Member Function Documentation

void TextureContext::clear_dirty_flags (  int  flags_to_clear = ~0  )  [inline, inherited]
 

Removes the indicated flags from the "dirty" bits.

See mark_dirty().

The value is the union of all the bits that are to be cleared; if a bit is set in the parameter, it will be removed from the dirty set. Bits that are not set in this parameter are left unchanged.

This function is intended to be called by the GSG after it has updated the texture parameters.

size_t TextureContext::estimate_texture_memory (   )  [virtual, inherited]
 

Estimates the amount of texture memory that will be consumed by loading this texture.

This is mainly useful for debugging and reporting purposes.

Returns a value in bytes.

virtual TypeHandle DXTextureContext7::force_init_type (  void   )  [inline, virtual]
 

Reimplemented from TextureContext.

Definition at line 77 of file dxTextureContext7.h.

unsigned int DXTextureContext7::get_bits_per_pixel (  PixelBuffer::Format  format,
int *  alphbits
)  [protected]
 

Maps from the PixelBuffer's Format symbols to bpp.

returns # of alpha bits Note: PixelBuffer's format indicates REQUESTED final format, not the stored format, which is indicated by pixelbuffer type

TypeHandle DXTextureContext7::get_class_type (  void   )  [inline, static]
 

Reimplemented from TextureContext.

Definition at line 66 of file dxTextureContext7.h.

int TextureContext::get_dirty_flags (   )  const [inline, inherited]
 

Returns the current state of the dirty flags.

If this is non-zero, it represents the union of all properties that have been changed since the last call to clear_dirty_flags().

This function is intended to be called by the GSG to determine what properties need to be updated. See Texture::DirtyFlags for a list of possible bits.

virtual TypeHandle DXTextureContext7::get_type (  void   )  const [inline, virtual]
 

Reimplemented from TextureContext.

Definition at line 74 of file dxTextureContext7.h.

int TypedObject::get_type_index (   )  const [inline, inherited]
 

Returns the internal index number associated with this object's TypeHandle, a unique number for each different type.

This is equivalent to get_type().get_index().

Definition at line 71 of file typedObject.I.

void DXTextureContext7::init_type (  void   )  [inline, static]
 

This function is declared non-inline to work around a compiler bug in g++ 2.96.

Making it inline seems to cause problems in the optimizer.

Reimplemented from TextureContext.

References TextureContext::get_class_type().

bool TypedObject::is_exact_type (  TypeHandle  handle  )  const [inline, inherited]
 

Returns true if the current object is the indicated type exactly.

bool TypedObject::is_of_type (  TypeHandle  handle  )  const [inline, inherited]
 

Returns true if the current object is or derives from the indicated type.

void TextureContext::mark_dirty (  int  flags_to_set  )  [inline, inherited]
 

Marks the context "dirty", i.e.

its properties are different from the last time the GSG has seen them. Presumably, the GSG will respond by updating the properties and clearing the dirty bits the next time it renders the texture.

The value is the union of all the bits that are to be set dirty; bits that are not set in this parameter are left unchanged. See Texture::DirtyFlags for a list of available bits.

Usually this function is not called directly, but rather is called by Texture::mark_dirty() as a result of changing properties directly on the texture.
