|
| unsigned int | samplesToConvergence = HdEmbreeDefaultSamplesToConvergence |
| | How many samples do we need before a pixel is considered converged?
|
| |
| unsigned int | tileSize = HdEmbreeDefaultTileSize |
| | How many pixels are in an atomic unit of parallel work? A work item is a square of size [tileSize x tileSize] pixels.
|
| |
| unsigned int | ambientOcclusionSamples = HdEmbreeDefaultAmbientOcclusionSamples |
| | How many ambient occlusion rays should we generate per camera ray?
|
| |
| bool | jitterCamera = HdEmbreeDefaultJitterCamera |
| | Should the renderpass jitter camera rays for antialiasing?
|
| |
| bool | useFaceColors = HdEmbreeDefaultUseFaceColors |
| | Should the renderpass use the color primvar, or flat white colors? (Flat white shows off ambient occlusion better).
|
| |
| float | cameraLightIntensity = HdEmbreeDefaultCameraLightIntensity |
| | What should the intensity of the camera light be, specified as a percent of <1, 1, 1>.
|
| |
| int | randomNumberSeed = HdEmbreeDefaultRandomNumberSeed |
| | Seed to give to the random number generator.
|
| |
| bool | useLighting = HdEmbreeDefaultUseLighting |
| | Should the renderpass use scene lights (in particular, UsdLux-compliant area lights)? Note that if scene lights and ambient occlusion are both enabled, the renderer will choose scene lights rather than ambient occlusion.

This class is a singleton, holding configuration parameters for HdEmbree.
Everything is provided with a default, but can be overridden using environment variables before launching a hydra process.
Many of the parameters can be used to control quality/performance tradeoffs, or to alter how HdEmbree takes advantage of parallelism.
At startup, this class will print config parameters if HDEMBREE_PRINT_CONFIGURATION is true. Integer values greater than zero are considered "true".
Definition at line 39 of file config.h.
| float cameraLightIntensity = HdEmbreeDefaultCameraLightIntensity |
What should the intensity of the camera light be, specified as a percent of <1, 1, 1>.
For example, 300 would be <3, 3, 3>.
Override with HDEMBREE_CAMERA_LIGHT_INTENSITY.
Definition at line 82 of file config.h.
| bool jitterCamera = HdEmbreeDefaultJitterCamera |
Should the renderpass jitter camera rays for antialiasing?
Override with HDEMBREE_JITTER_CAMERA. The case-insensitive strings "true", "yes", "on", and "1" are considered true; an empty value uses the default, and all other values are false.
Definition at line 68 of file config.h.
| int randomNumberSeed = HdEmbreeDefaultRandomNumberSeed |
Seed to give to the random number generator.
A value of anything other than -1, combined with setting PXR_WORK_THREAD_LIMIT=1, should give deterministic / repeatable results. A value of -1 (the default) will allow the implementation to set a value that varies from invocation to invocation and thread to thread.
Override with HDEMBREE_RANDOM_NUMBER_SEED.
Definition at line 91 of file config.h.
| bool useFaceColors = HdEmbreeDefaultUseFaceColors |
Should the renderpass use the color primvar, or flat white colors? (Flat white shows off ambient occlusion better).
Override with HDEMBREE_USE_FACE_COLORS. The case-insensitive strings "true", "yes", "on", and "1" are considered true; an empty value uses the default, and all other values are false.
Definition at line 76 of file config.h.
| bool useLighting = HdEmbreeDefaultUseLighting |
Should the renderpass use scene lights (in particular, UsdLux-compliant area lights)? Note that if scene lights and ambient occlusion are both enabled, the renderer will choose scene lights rather than ambient occlusion.
Override with HDEMBREE_USE_LIGHTING.
