Member Function Documentation

◆ create_texture()

bool DXTextureContext9::create_texture ( DXScreenData scrn)

Use panda texture's pixelbuffer to create a texture for the specified device.

This code gets the attributes of the texture from the bitmap, creates the texture, and then copies the bitmap into the texture. The return value is true if the texture is successfully created, false otherwise.

References TextureContext::get_texture().

◆ d3d_surface_to_texture()

HRESULT DXTextureContext9::d3d_surface_to_texture ( RECT &  source_rect,
IDirect3DSurface9 *  d3d_surface,
bool  inverted,
Texture result,
int  view,
int  z 
)
static

copies source_rect in pD3DSurf to upper left of texture

Definition at line 1431 of file dxTextureContext9.cxx.

References Texture::get_num_components.

◆ delete_texture()

void DXTextureContext9::delete_texture ( )

Release the surface used to store the texture.

Definition at line 1173 of file dxTextureContext9.cxx.

Referenced by evict_lru(), and DXGraphicsStateGuardian9::upload_texture().

◆ evict_lru()

void DXTextureContext9::evict_lru ( )
virtual

Evicts the page from the LRU.

Called internally when the LRU determines that it is full. May also be called externally when necessary to explicitly evict the page.

It is legal for this method to either evict the page as requested, do nothing (in which case the eviction will be requested again at the next epoch), or requeue itself on the tail of the queue (in which case the eviction will be requested again much later).

Reimplemented from AdaptiveLruPage.

◆ extract_texture_data()

bool DXTextureContext9::extract_texture_data ( DXScreenData screen)

This method will be called in the draw thread to download the texture memory's image into its ram_image value.

It returns true on success, false otherwise.

◆ get_d3d_cube_texture()

IDirect3DCubeTexture9 * DXTextureContext9::get_d3d_cube_texture ( ) const

inline

Returns the Direct3D object that represents the texture, whatever kind of texture it is.

◆ get_d3d_volume_texture()

IDirect3DVolumeTexture9 * DXTextureContext9::get_d3d_volume_texture ( ) const
inline

Definition at line 45 of file dxTextureContext9.I.

◆ has_mipmaps()

bool DXTextureContext9::has_mipmaps ( ) const
inline

Returns true if the texture was created with mipmaps, false otherwise.
