Member Function Documentation

◆ apply_index_buffer()

bool DXGraphicsStateGuardian9::apply_index_buffer ( IndexBufferContext ibc,
const GeomPrimitivePipelineReader reader,
bool  force 
)

Updates the index buffer with the current data, and makes it the current index buffer for rendering.

Definition at line 644 of file dxGraphicsStateGuardian9.cxx.

◆ apply_texture()

void DXGraphicsStateGuardian9::apply_texture ( int  i,
TextureContext tc,
const SamplerState sampler 
)

Makes the texture the currently available texture for rendering on the ith stage.

Definition at line 209 of file dxGraphicsStateGuardian9.cxx.

◆ apply_vertex_buffer()

bool DXGraphicsStateGuardian9::apply_vertex_buffer ( VertexBufferContext vbc,
const GeomVertexArrayDataHandle reader,
bool  force 
)

Updates the vertex buffer with the current data, and makes it the current vertex buffer for rendering.

Definition at line 515 of file dxGraphicsStateGuardian9.cxx.

◆ atexit_function()

void DXGraphicsStateGuardian9::atexit_function ( void  )
static

This function is passed to the atexit function.

Definition at line 5375 of file dxGraphicsStateGuardian9.cxx.

References set_cg_device(), and static_set_gamma().

◆ begin_draw_primitives()

bool DXGraphicsStateGuardian9::begin_draw_primitives ( const GeomPipelineReader geom_reader,
const GeomVertexDataPipelineReader data_reader,
bool  force 
)
virtual

Called before a sequence of draw_primitive() functions are called, this should prepare the vertex data for rendering.

It returns true if the vertices are ok, false to abort this group of primitives.

Reimplemented from GraphicsStateGuardian.

Definition at line 1148 of file dxGraphicsStateGuardian9.cxx.

References GraphicsStateGuardian::begin_draw_primitives().

◆ begin_frame()

bool DXGraphicsStateGuardian9::begin_frame ( Thread current_thread)
virtual

Called before each frame is rendered, to allow the GSG a chance to do any internal cleanup before beginning the frame.

The return value is true if successful (in which case the frame will be drawn and end_frame() will be called later), or false if unsuccessful (in which case nothing will be drawn and end_frame() will not be called).

Reimplemented from GraphicsStateGuardian.

Definition at line 968 of file dxGraphicsStateGuardian9.cxx.

References GraphicsStateGuardian::begin_frame().

◆ begin_occlusion_query()

void DXGraphicsStateGuardian9::begin_occlusion_query ( )
virtual

Begins a new occlusion query.

After this call, you may call begin_draw_primitives() and draw_triangles()/draw_whatever() repeatedly. Eventually, you should call end_occlusion_query() before the end of the frame; that will return a new OcclusionQueryContext object that will tell you how many pixels represented by the bracketed geometry passed the depth test.

It is not valid to call begin_occlusion_query() between another begin_occlusion_query() .. end_occlusion_query() sequence.

Reimplemented from GraphicsStateGuardian.

Definition at line 716 of file dxGraphicsStateGuardian9.cxx.

◆ begin_scene()

bool DXGraphicsStateGuardian9::begin_scene ( )
virtual

Called between begin_frame() and end_frame() to mark the beginning of drawing commands for a "scene" (usually a particular DisplayRegion) within a frame.

All 3-D drawing commands, except the clear operation, must be enclosed within begin_scene() .. end_scene().

The return value is true if successful (in which case the scene will be drawn and end_scene() will be called later), or false if unsuccessful (in which case nothing will be drawn and end_scene() will not be called).

◆ check_dx_allocation()

bool DXGraphicsStateGuardian9::check_dx_allocation ( HRESULT  result,
int  allocation_size,
int  attempts 
)

This function is called after the creation of textures, vertex buffers, and index buffers to check if DirectX is out of memory.

If DirectX is out of memory and the LRU is being used, then page out some memory. This function is a fail-safe just in case another process allocates video memory, DirectX is fragmented, or there are some borderline memory allocation cases, ...

bool DXGraphicsStateGuardian9::do_framebuffer_copy_to_ram ( Texture tex,
int  view,
int  z,
const DisplayRegion dr,
const RenderBuffer rb,
bool  inverted 
)

This is the implementation of framebuffer_copy_to_ram(); it adds one additional parameter, which should be true if the framebuffer is to be inverted during the copy (as in the same way it copies to texture memory).

◆ prepare_index_buffer()

IndexBufferContext * DXGraphicsStateGuardian9::prepare_index_buffer ( GeomPrimitive data)
virtual

Creates a new retained-mode representation of the given data, and returns a newly-allocated IndexBufferContext pointer to reference it.

It is the responsibility of the calling function to later call release_index_buffer() with this same pointer (which will also delete the pointer).

This function should not be called directly to prepare a buffer. Instead, call Geom::prepare().

Reimplemented from GraphicsStateGuardian.

Definition at line 634 of file dxGraphicsStateGuardian9.cxx.

◆ prepare_lens()

bool DXGraphicsStateGuardian9::prepare_lens ( )
virtual

Makes the current lens (whichever lens was most recently specified with set_scene()) active, so that it will transform future rendered geometry.

Normally this is only called from the draw process, and usually it is called by set_scene().

The return value is true if the lens is acceptable, false if it is not.

◆ prepare_texture()

TextureContext * DXGraphicsStateGuardian9::prepare_texture ( Texture tex,
int  view 
)
virtual

Creates a new retained-mode representation of the given texture, and returns a newly-allocated TextureContext pointer to reference it.

It is the responsibility of the calling function to later call release_texture() with this same pointer (which will also delete the pointer).

This function should not be called directly to prepare a texture. Instead, call Texture::prepare().

◆ prepare_vertex_buffer()

VertexBufferContext * DXGraphicsStateGuardian9::prepare_vertex_buffer ( GeomVertexArrayData data)
virtual

Creates a new retained-mode representation of the given data, and returns a newly-allocated VertexBufferContext pointer to reference it.

It is the responsibility of the calling function to later call release_vertex_buffer() with this same pointer (which will also delete the pointer).

This function should not be called directly to prepare a buffer. Instead, call Geom::prepare().

◆ release_index_buffer()

void DXGraphicsStateGuardian9::release_index_buffer ( IndexBufferContext ibc)
virtual

Frees the GL resources previously allocated for the data.

This function should never be called directly; instead, call Data::release() (or simply let the Data destruct).

Reimplemented from GraphicsStateGuardian.

Definition at line 699 of file dxGraphicsStateGuardian9.cxx.

◆ release_shader()

void DXGraphicsStateGuardian9::release_shader ( ShaderContext sc)

This function should never be called directly; instead, call Data::release() (or simply let the Data destruct).

Reimplemented from GraphicsStateGuardian.

Definition at line 578 of file dxGraphicsStateGuardian9.cxx.

◆ reset()

void DXGraphicsStateGuardian9::reset ( )
virtual

Resets all internal state as if the gsg were newly created.

The GraphicsWindow pointer represents a typical window that might be used for this context; it may be required to set up the frame buffer properly the first time.

◆ set_state_and_transform()

void DXGraphicsStateGuardian9::set_state_and_transform ( const RenderState target,
const TransformState transform 
)
virtual

Simultaneously resets the render state and the transform state.

This transform specified is the "internal" net transform, already converted into the GSG's internal coordinate space by composing it to get_cs_transform(). (Previously, this used to be the "external" net transform, with the assumption that that GSG would convert it internally, but that is no longer the case.)

Special case: if (state==NULL), then the target state is already stored in _target.

◆ setup_array_data()

bool DXGraphicsStateGuardian9::setup_array_data ( DXVertexBufferContext9 *&  dvbc,
const GeomVertexArrayDataHandle array_reader,
bool  force 
)

Internal function to bind a buffer object for the indicated data array, if appropriate, or to unbind a buffer object if it should be rendered from client memory.

If the buffer object is bound, this function sets client_pointer to NULL (representing the start of the buffer object in server memory); if the buffer object is not bound, this function sets client_pointer the pointer to the data array in client memory, that is, the data array passed in.

If force is not true, the function may return false indicating the data is not currently available.

◆ update_texture()

bool DXGraphicsStateGuardian9::update_texture ( TextureContext tc,
bool  force 
)
virtual

Ensures that the current Texture data is refreshed onto the GSG.

This means updating the texture properties and/or re-uploading the texture image, if necessary. This should only be called within the draw thread.

If force is true, this function will not return until the texture has been fully uploaded. If force is false, the function may choose to upload a simple version of the texture instead, if the texture is not fully resident (and if get_incomplete_render() is true).
