Member Function Documentation

◆ GetCamera()

HdCamera const* GetCamera ( ) const
inline

Get camera.

Definition at line 99 of file renderPassState.h.

◆ GetClipPlanes()

virtual HD_API ClipPlanesVector const& GetClipPlanes ( ) const
virtual

Returns HdCamera's clip planes.

Reimplemented in HdStRenderPassState.

◆ GetFraming()

const CameraUtilFraming& GetFraming ( ) const
inline

Get framing information determining how the filmback plane maps to pixels.

Definition at line 104 of file renderPassState.h.

◆ GetImageToWorldMatrix()

HD_API GfMatrix4d GetImageToWorldMatrix ( ) const

Compute a transform from window relative coordinates (x,y,z,1) to homogeneous world coordinates (x,y,z,w), using the HdCamera's attributes, framing, and viewport dimensions.

◆ GetOverrideWindowPolicy()

const std::pair<bool, CameraUtilConformWindowPolicy>& GetOverrideWindowPolicy ( ) const
inline

The override value for the window policy to conform the camera frustum that can be specified by the application.

Definition at line 109 of file renderPassState.h.

◆ GetProjectionMatrix()

virtual HD_API GfMatrix4d GetProjectionMatrix ( ) const
virtual

Compute projection matrix using physical attributes of an HdCamera.

Reimplemented in HdStRenderPassState.

◆ GetViewport()

GfVec4f const& GetViewport ( ) const
inline

Only use when clients did not specify a camera framing.

Deprecated:

Definition at line 140 of file renderPassState.h.

◆ GetWindowPolicy()

HD_API CameraUtilConformWindowPolicy GetWindowPolicy ( ) const

The resolved window policy to conform the camera frustum.

This is either the override value specified by the application or the value from the scene delegate's camera.

◆ GetWorldToViewMatrix()

virtual HD_API GfMatrix4d GetWorldToViewMatrix ( ) const
virtual

Camera getter API.

Returns inverse of HdCamera's transform.

Reimplemented in HdStRenderPassState.

◆ Prepare()

virtual HD_API void Prepare ( HdResourceRegistrySharedPtr const &  resourceRegistry)
virtual

Schedule to update renderPassState parameters.

e.g. camera matrix, override color, id blend factor. Prepare, called once per frame after the sync phase, but prior to the commit phase.

Reimplemented in HdStRenderPassState.

◆ SetAovBindings()

HD_API void SetAovBindings ( HdRenderPassAovBindingVector const &  aovBindings)

Set the attachments for this renderpass to render into.

◆ SetAovInputBindings()

HD_API void SetAovInputBindings ( HdRenderPassAovBindingVector const &  aovBindings)

Set the AOVs that this renderpass needs to read from.

◆ SetCameraAndFraming()

HD_API void SetCameraAndFraming ( HdCamera const *  camera,
CameraUtilFraming const &  framing,
const std::pair< bool, CameraUtilConformWindowPolicy > &  overrideWindowPolicy 
)

Camera setter API.

Sets the camera transform (aka view inverse matrix) and physical parameters, the framing information and a possible overide value for the window policy used to conform the camera frustum if its aspect ratio is not matching the display window.

Note: using std::pair<bool, ...> here instead of std::optional<...> since the latter is only available in C++17 or later.

◆ SetCameraAndViewport()

HD_API void SetCameraAndViewport ( HdCamera const *  camera,
GfVec4d const &  viewport 
)

Camera setter API The view, projection and clipping plane info of the camera will be used.

Deprecated:
Use the more expressive SetCameraAndFraming instead.

◆ SetLightingEnabled()

HD_API void SetLightingEnabled ( bool  enabled)

XXX: Hacky way of disabling lighting.

◆ SetOverrideColor()

HD_API void SetOverrideColor ( GfVec4f const &  color)

Set an override color for rendering where the R, G and B components are the color and the alpha component is the blend value.

◆ SetPointColor()

HD_API void SetPointColor ( GfVec4f const &  color)

Set a point color for rendering where the R, G and B components are the color and the alpha component is the blend value.

◆ SetPointSelectedSize()

HD_API void SetPointSelectedSize ( float  size)

Set the point size for selected points.

◆ SetPointSize()

HD_API void SetPointSize ( float  size)

Set the point size for unselected points.

◆ SetUseAovMultiSample()

HD_API void SetUseAovMultiSample ( bool  state)

Returns true if the render pass wants to render into the multi-sample aovs.

Returns false if the render wants to render into the resolve aovs.

◆ SetWireframeColor()

HD_API void SetWireframeColor ( GfVec4f const &  color)

Set a wireframe color for rendering where the R, G and B components are the color and the alpha component is the blend value.
