Member Function Documentation

OpenMayaRender.MRenderer.activeRenderOverride ( )

static

activeRenderOverride() -> string

Returns the name of the active override.

OpenMayaRender.MRenderer.copyTargetToScreen ( )

static

copyTargetToScreen(MRenderTarget) -> bool

Copy a render target to the screen.
If the target's dimensions are not the same as the active viewport it will be scaled up or down as necessary to fill the entire viewport.

OpenMayaRender.MRenderer.deregisterOverride ( )

static

deregisterOverride(MRenderOverride) -> None

Deregister an existing render override on the renderer.
The renderer will remove this override from it's list of registered overrides.

OpenMayaRender.MRenderer.disableChangeManagementUntilNextRefresh ( )

static

disableChangeManagementUntilNextRefresh() -> None

Calling this method will cause Viewport 2.0 to stop processing all changes to the Maya scene until the next viewport refresh.

OpenMayaRender.MRenderer.drawAPI ( )

static

drawAPI() -> int

Returns the current drawing API. Returns 'kNone' if the renderer is not initialized.

  MRenderer.kNone          Uninitialized device
  MRenderer.kOpenGL        OpenGL
  MRenderer.kDirectX11     Direct X 11
  MRenderer.kAllDevices    All : OpenGL and Direct X 11

OpenMayaRender.MRenderer.drawAPIIsOpenGL ( )

static

drawAPIIsOpenGL() -> bool

Returns whether the current drawing API is OpenGL or not

OpenMayaRender.MRenderer.drawAPIVersion ( )

static

drawAPIVersion() -> int

Returns the version of drawing API.

OpenMayaRender.MRenderer.findRenderOverride ( )

static

findRenderOverride(string) -> MRenderOverride

Returns a reference to an existing render override registered with the renderer.

OpenMayaRender.MRenderer.getFragmentManager ( )

static

getFragmentManager() -> MFragmentManager

Returns the fragment manager or None if the renderer is not initialized properly.

OpenMayaRender.MRenderer.getRenderTargetManager ( )

static

getRenderTargetManager() -> MRenderTargetManager

Returns the render target manager or None if the renderer is not initialized properly.

OpenMayaRender.MRenderer.getShaderManager ( )

static

getShaderManager() -> MShaderManager

Returns the shader manager or None if the renderer is not initialized properly.

OpenMayaRender.MRenderer.getTextureManager ( )

static

getTextureManager() -> MTextureManager

Returns the texture manager or None if the renderer is not initialized properly.

OpenMayaRender.MRenderer.GPUDeviceHandle ( )

static

GPUDeviceHandle() -> long

Returns a long containing a C++ 'void' pointer which points to the GPU "device".In the case that the drawing API is OpenGL then the "device" is a handle to an OpenGL context.
In the case that the drawing API is DirectX then the "device" is a pointer to a DirectX device.

OpenMayaRender.MRenderer.GPUmaximumPrimitiveCount ( )

static

GPUmaximumPrimitiveCount() -> int

Returns the maximum number of primitives that can be drawn per draw call by the GPU device.
0 if device has not been initialized.

OpenMayaRender.MRenderer.GPUmaximumVertexBufferSize ( )

static

GPUmaximumVertexBufferSize() -> int

Returns the maximum number of vertices allowed in a vertex buffer by the GPU device.
0 if device has not been initialized.

OpenMayaRender.MRenderer.needEvaluateAllLights ( )

static

needEvaluateAllLights() -> None

Notify the Viewport 2.0 renderer that it should evaluate all lights marked dirty, regardless of the light limit.For example, if there are 8 lights accessible because of the Viewport 2.0 light limit option, Only the first 8 non-ambient lights created will be evaluated.Call this method to instruct Viewport 2.0 to evaluate all dirty lights regardless of the light limit option.

Note that this method does NOT perform any DG evaluation when it is called.The actual evaluation does not occur until the next viewport refresh. This method is threadsafe. The viewport refresh will occur asynchronously.Multiple calls to this method will get merged.

Call this method may decrease performance in Viewport 2.0 during the next viewport refresh.Once this method is called, all unused lights that are marked dirty will be evaluated in the next viewport refresh.

An example application of this method is to obtain light information while ignoring the light limit.If this method is not called, information on unused lights cannot be obtained via MDrawContext, even if LightFilter is set to kFilteredToLightLimit.This is because unused lights are not evaluated automatically by Viewport 2.0 by default.

OpenMayaRender.MRenderer.outputTargetSize ( )

static

outputTargetSize() -> [int, int]

Get target size in format [width, height].

OpenMayaRender.MRenderer.registerOverride ( )

static

registerOverride(MRenderOverride) -> None

Register the override as being usable by the renderer.
If the override is already registered it will not be registered again.

OpenMayaRender.MRenderer.renderOverrideCount ( )

static

renderOverrideCount() -> int

Returns the number of registered render overrides.

OpenMayaRender.MRenderer.renderOverrideName ( )

static

renderOverrideName() -> string

Get the current render override name used for batch rendering.
If there is no override then an empty string will be returned.

OpenMayaRender.MRenderer.setGeometryDrawDirty ( )

static

setGeometryDrawDirty(object, topologyChanged=True) -> None

Notify the Viewport 2.0 renderer that the geometry (size, shape, etc.) of object has changed, causing the object to be updated in the viewport.

* object (MObject) - DAG object which has been modified.
* topologyChanged (bool) - has the object topology changed

OpenMayaRender.MRenderer.setLightRequiresShadows ( )

static

setLightRequiresShadows(object, flag) -> bool

This method allows for plug-in writers to indicate that the shadow map contents for a given light are required, regardless of the light limit.
Returns True if the method added or removed the request successfully.

* object (MObject) - Light to request shadow update for
* flag (bool) - Indicate if an update is requested. When set to true a request is added, and when set false any existing request is removed.

OpenMayaRender.MRenderer.setLightsAndShadowsDirty ( )

static

setLightsAndShadowsDirty() -> None

Notify the Viewport 2.0 renderer that something has changed which requires re-evaluation of lighting and shadows.

OpenMayaRender.MRenderer.setRenderOverrideName ( )

static

setRenderOverrideName(string) -> bool

Set the name of a render override (MRenderOverride) for batch rendering.
