OpenGl_Element () | |
virtual void | Render (const Handle< OpenGl_Workspace > &theWorkspace) const =0 |
virtual void | Release (OpenGl_Context *theContext)=0 |
Release GPU resources. Pointer to the context is used because this method might be called when the context is already being destroyed and usage of a handle would be unsafe. More... | |
virtual Standard_Boolean | IsFillDrawMode () const |
Return TRUE if primitive type generates shaded triangulation (to be used in filters). More... | |
virtual Standard_Size | EstimatedDataSize () const |
Returns estimated GPU memory usage for holding data without considering overheads and allocation alignment rules. More... | |
virtual void | UpdateMemStats (Graphic3d_FrameStatsDataTmp &theStats) const |
Increment memory usage statistics. Default implementation puts EstimatedDataSize() into Graphic3d_FrameStatsCounter_EstimatedBytesGeom. More... | |
virtual void | UpdateDrawStats (Graphic3d_FrameStatsDataTmp &theStats, bool theIsDetailed) const |
Increment draw calls statistics. More... | |
virtual void | SynchronizeAspects () |
Update parameters of the drawable elements. More... | |
virtual void | DumpJson (Standard_OStream &theOStream, Standard_Integer theDepth=-1) const |
Dumps the content of me into the stream. More... | |

Pointer to the context is used because this method might be called when the context is already being destroyed and usage of a handle would be unsafe.
|
virtual |
Dumps the content of me into the stream.
Reimplemented in OpenGl_Text, OpenGl_PrimitiveArray, OpenGl_Aspects, OpenGl_GraduatedTrihedron, OpenGl_FrameStatsPrs, OpenGl_Flipper, and OpenGl_StencilTest.
|
inlinevirtual |
Returns estimated GPU memory usage for holding data without considering overheads and allocation alignment rules.
Reimplemented in OpenGl_Text, and OpenGl_PrimitiveArray.
|
inlinevirtual |
Return TRUE if primitive type generates shaded triangulation (to be used in filters).
Reimplemented in OpenGl_PrimitiveArray.
|
pure virtual |
Release GPU resources. Pointer to the context is used because this method might be called when the context is already being destroyed and usage of a handle would be unsafe.
Implemented in OpenGl_Aspects, OpenGl_Text, OpenGl_PrimitiveArray, OpenGl_GraduatedTrihedron, OpenGl_Flipper, OpenGl_FrameStatsPrs, and OpenGl_StencilTest.

pure virtual |
Implemented in OpenGl_Aspects, OpenGl_Text, OpenGl_PrimitiveArray, OpenGl_GraduatedTrihedron, OpenGl_Flipper, OpenGl_FrameStatsPrs, and OpenGl_StencilTest.
|
inlinevirtual |
Update parameters of the drawable elements.
Reimplemented in OpenGl_Aspects.
|
virtual |
Increment draw calls statistics.
theStats | [in] [out] frame counters to increment |
theIsDetailed | [in] indicate detailed dump (more counters - number of triangles, points, etc.) |
Reimplemented in OpenGl_Text, and OpenGl_PrimitiveArray.
|
virtual |
Increment memory usage statistics. Default implementation puts EstimatedDataSize() into Graphic3d_FrameStatsCounter_EstimatedBytesGeom.
